Answer:
A) 14
Step-by-step explanation:
When a small is gear connected to a larger gear, the smaller gear makes more revolutions than the larger gear. Use the ratio of the numbers of teeth to find the ratio of the numbers of revolution.
1 gear has 9 teeth
1 gear has 27 teeth
27/9 = 3
The ratio is 3:1.
The small gear makes 3 revolutions for each revolutuion of the large gear.
The large gear makes 1/3 revolution for each revolution of the small gear.
Here, the small gear makes 42 revolutions.
42/3 = 14
The large gear makes 14 revolutions.
Answer: A) 14
The larger gear has made 14 revolutions when the smaller gear has made 42 revolutions. This is because the ratio of the teeth on the gears is 1:3, which is also the ratio of their revolutions.
Explanation:The ratio of the number of teeth on the two gears is also the ratio of the number of rotations they make. In this case, the smaller gear has 9 teeth and the larger gear has 27 teeth. So, the ratio is 9:27, which simplifies to 1:3.
This means that for every one rotation of the larger gear, the smaller gear will make three rotations.
Since the smaller gear has made 42 rotations, to figure out the number of rotations the larger gear has made, you would divide 42 by 3. (because of the 1:3 ratio). The answer is 14.
Therefore, the larger gear has made 14 revolutions when the smaller gear has made 42 revolutions. So, the correct answer is A) 14.

a librarian has weekends off and has 10 paid vacation days per year, including holidays that fall on weekends. If his salary is 32,500 per year, what is his pay per workday?
his pay per workday will be $127.45.
How to calculate interest?Thus, the formula for calculating simple interest is J = C i t, where J is interest, C is principal, i is interest rate, and t is time. That is, J represents the amount added to the initial value, the capital is the calculation basis, the interest rate is the percentage applied on the capital and time is the capitalization period.
Knowing that:
10 paid vacation days per yearsalary is 32,500 per yearThe total weekends in a year:
52 * 2 = 104 weekend days.
Total paid vacation days, including holidays that fall on weekends:
10 - 4 = 6 paid vacation days.
Total non-working days:
104 + 6 = 110 non-working days.
Total working days in a year:
365 - 110 = 255 working days.
Pay per workday = Annual salary / Total working days
= $32,500 / 255= $127.45
Therefore, the librarian's pay per workday is approximately $127.45.

The difference in height is 400 metres.
What is the difference in height of Mount St. Helens?Height refers to vertical distance from the top to the object's base. Occasionally, it is also labeled as an altitude which measures from down to top of a surface.
To get difference in height, we will subtract the height after the eruption from the height before the eruption:
Given:
Height before eruption = 2.95 kilometers
Height after eruption = 2.55 kilometers
Difference in height = Height before eruption - Height after eruption
Difference in height = 2.95 km - 2.55 km
Difference in height = 0.4 kilometers
0.4 kilometers to metres will be:
= 0.4 * 1000 metres
= 400 metres.

face pard He then decides to push the brick like a loy car 311 Mention the transformation of the brick when it is flipped or turned sideways $72 When the key is pushing the brick, without using or flipping the brick, what * What are the two differences between a rectangle and a paralelogram?
1. All angles of a rectangle are right angles (90 degrees), while the angles of a parallelogram can be any angle other than 90 degrees.
2. The opposite sides of a rectangle are equal in length, whereas in a parallelogram, opposite sides are of equal length as well, but they may not be perpendicular to each other.
The questions are a bit unclear and have some spelling errors, but I will try my best to provide an answer:
- Mention the transformation of the brick when it is flipped or turned sideways:
If the brick is flipped over, the transformation it undergoes is called a reflection. This can also be thought of as a mirror image of the original brick. If the brick is turned sideways, the transformation it undergoes is called a rotation. In a rotation, the object is turned about a point, and the image of the object appears to have been rotated around that point.

In summary, the transformation of a flipped brick is a reflection, while a turned sideways brick undergoes a rotation. The differences between a rectangle and a parallelogram include the angles (all right angles for a rectangle and any angle other than 90 degrees for a parallelogram) and the opposite sides (equal length and perpendicular for a rectangle, equal length but not necessarily perpendicular for a parallelogram).

Line r is steeper than line
Line s
has a negative slope.
Line s has a negative slope.
Line s
is steeper than line r.
Line s is steeper than line
Line r
has a negative slope.
Answer: To determine which statement is true about lines r and s, we need to compare their slopes.
The slope of a line can be calculated using the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
For line r, using the points (-5, 2) and (-3, 8):
slope_r = (8 - 2) / (-3 - (-5))
= 6 / 2
= 3
For line s, using the points (-6, 4) and (2, 12):
slope_s = (12 - 4) / (2 - (-6))
= 8 / 8
= 1
Now, let's analyze the statements:
Line r is steeper than line s. (False)
Since the slope of line r (3) is greater than the slope of line s (1), this statement is true.
Line r is steeper than line (Incomplete statement)
This statement is incomplete.
Line s has a negative slope. (False)
The slope of line s (1) is positive, not negative. So, this statement is false.
Line s is steeper than line r. (False)
Since the slope of line s (1) is less than the slope of line r (3), this statement is false.
Line r has a negative slope. (False)
The slope of line r (3) is positive, not negative. So, this statement is false.
Based on the analysis, the true statement about lines r and s is:
Line r is steeper than line s.

how do you find out the area of a tent, floor included
To find the area of a tent, including the floor, we need to measure or determine the dimensions of both the tent's floor and any additional areas such as vestibules or extensions.
Floor Area: Measure the length and width of the tent's floor in the same unit of measurement (e.g., feet or meters). Multiply the length by the width to calculate the floor area. For example, if the length is 8 feet and the width is 6 feet, the floor area would be 8 feet * 6 feet = 48 square feet.Additional Areas: If the tent has vestibules, extensions, or any other separate areas, measure each area's dimensions and calculate their individual areas separately.Total Area: Once you have calculated the individual areas of the floor and any additional areas, simply add them together to find the total area of the tent, including the floor. For example, if the floor area is 48 square feet and there is an additional vestibule area of 10 square feet, the total area would be 48 square feet + 10 square feet = 58 square feet.Learn more about the area of the tent here:

A rectangle has 2 sides that are each 6 centimeters lo[ng. The perimeter is 22 centimeters. How long are the other sides?
Answer:
The other sides = 5 centimeters.
Step-by-step explanation:
Let's assume the length of the other two sides of the rectangle is "x" centimeters.
A rectangle has two pairs of equal sides. Therefore, we can set up the equation for the perimeter of the rectangle:
Perimeter = 2(length + width)
Given:
Length = 6 centimeters
Perimeter = 22 centimeters
Using the equation, we can substitute the given values:
22 = 2(6 + x)
Simplifying further:
22 = 12 + 2x
Subtracting 12 from both sides:
10 = 2x
Dividing both sides by 2:
5 = x
Therefore, the length of the other two sides of the rectangle is 5 centimeters.

To find the measure of angle AB, we can use the fact that the sum of the angles in a triangle is 180 degrees.
Given:
Angle A = 65 degrees
Angle B = 91 degrees
We can subtract the sum of these two angles from 180 degrees to find angle AB:
Angle AB = 180 - (Angle A + Angle B)
Angle AB = 180 - (65 + 91)
Angle AB = 180 - 156
Angle AB = 24 degrees
Therefore, the measure of angle AB is 24 degrees.

If D = 2w? - w - 7 and C = 3w - 6, find an expression that equals D + 3C in
standard form.
The expression that equals D + 3C in standard form is 2w² + 8w - 25.
To find an expression that equals D + 3C in standard form, we first need to simplify D and C.
Starting with D = 2w² - w - 7, we can rearrange the terms to put it in standard form:
D = 2w² - w - 7
D = 2w² - 2w + w - 7
D = 2w(w - 1) + (w - 7)
Next, simplifying C = 3w - 6:
C = 3w - 6
Now, we can substitute these expressions into D + 3C:
D + 3C = (2w² - w - 7) + 3(3w - 6)
Expanding and simplifying:
D + 3C = 2w² - w - 7 + 9w - 18
D + 3C = 2w² + 8w - 25

Answer: 59,048
Step-by-step explanation:
To find the sum of the given finite series:
Σ2· (3)n-1
n=1
where n ranges from 1 to 10, we can use the formula for the sum of a geometric series.
The formula for the sum of a geometric series is:
S = a * (r^n - 1) / (r - 1)
In this case, a = 2 (the first term of the series) and r = 3 (the common ratio).
Using the formula, we can calculate the sum:
S = 2 * (3^10 - 1) / (3 - 1)
= 2 * (59049 - 1) / 2
= (118098 - 2) / 2
= 118096 / 2
= 59048
Therefore, the sum of the given finite series is 59,048.
Work out the integer values
Please help, I attached a photo.
Step by step explanation if possible :)))
The integers that satisfy the inequality are -1, 0, 1, and 2.
To find the integer values that satisfy the inequality x < 6/(x - 1), we can start by analyzing the domain of the expression.
First, note that the denominator (x - 1) cannot be equal to zero since division by zero is undefined. Therefore, we must exclude x = 1 from the domain.
Next, consider the sign of the expression 6/(x - 1). When the denominator (x - 1) is positive, the expression will be positive. Similarly, when the denominator is negative, the expression will be negative.
Considering the inequality x < 6/(x - 1), we can divide the problem into two cases based on the sign of (x - 1):
Case 1: (x - 1) > 0
In this case, the expression 6/(x - 1) is positive. To satisfy the inequality x < 6/(x - 1), x must be less than the positive value of 6/(x - 1). Since the denominator is positive, we can drop the absolute value sign. Therefore, the inequality becomes:
x < 6/(x - 1)
Case 2: (x - 1) < 0
In this case, the expression 6/(x - 1) is negative. To satisfy the inequality x < 6/(x - 1), x must be greater than the negative value of 6/(x - 1). Since the denominator is negative, we need to flip the inequality sign and change the direction. Therefore, the inequality becomes:
x > 6/(x - 1)
Now, let's solve each case separately:
Case 1: (x - 1) > 0
Since the denominator (x - 1) is positive, we can multiply both sides of the inequality by (x - 1) without changing the direction of the inequality. This gives:
x(x - 1) < 6
Expanding the left side:
x² - x < 6
Rearranging the inequality:
x² - x - 6 < 0
Now we can factorize the quadratic:
(x - 3)(x + 2) < 0
To determine the solution, we need to consider the sign of the expression for different intervals:
When x < -2, both factors are negative, so the expression is positive.
When -2 < x < 3, the first factor (x - 3) is negative, and the second factor (x + 2) is positive, so the expression is negative.
When x > 3, both factors are positive, so the expression is positive.
Therefore, the solution to Case 1 is:
-2 < x < 3
Case 2: (x - 1) < 0
Since the denominator (x - 1) is negative, we need to flip the inequality sign. Multiplying both sides of the inequality by (x - 1) changes the direction of the inequality. This gives:
x(x - 1) > 6
Expanding the left side:
x² - x > 6
Rearranging the inequality:
x² - x - 6 > 0
Factoring the quadratic:
(x - 3)(x + 2) > 0
Considering the sign of the expression for different intervals:
When x < -2, both factors are negative, so the expression is positive.
When -2 < x < 3, the first factor (x - 3) is negative, and the second factor (x + 2) is positive, so the expression is negative.
When x > 3, both factors are positive, so the expression is positive.
Therefore, there are no solutions in Case 2.
Combining the solutions from both cases, we find that the integer values satisfying the inequality x < 6/(x - 1) are:
-2 < x < 3
In other words, the integers that satisfy the inequality are -1, 0, 1, and 2.

What is the unit rate if you drove a go-kart 9 miles in 36 minutes?
Answer:
Step-by-step explanation:
To find the unit rate, we need to divide the distance traveled by the time taken.
In this case, the distance traveled is 9 miles, and the time taken is 36 minutes.
Unit rate = distance/time
Unit rate = 9 miles / 36 minutes
Simplifying the above expression by dividing both numerator and denominator by 9, we get:
Unit rate = 1 mile / 4 minutes
Therefore, the unit rate at which the go-kart is traveling is 1 mile per 4 minutes.
1. ¬{[Q → (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) ∴ ¬(Q ∧ P) ∨ (T ∧ R)
2. [(T ∨ Q) → (T ∨ S)] ∨ [(T ∨ Q) → (T ∨ S)]
Given statement solution is :- Regardless of the values of T, Q, and S, the whole Valid Statements & Implications is always true.
Let's analyze the two given statements:
¬{[Q → (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) ∴ ¬(Q ∧ P) ∨ (T ∧ R)
To prove this statement, we can use logical equivalences and deductions:
¬{[Q → (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) (Given)
¬{[¬Q ∨ (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) (Implication equivalence)
¬{[(¬Q ∨ ¬S) ∧ (¬Q ∨ R)] ∨ ¬P} → (¬P ↔ P) (Implication equivalence)
¬{(¬Q ∨ ¬S ∨ ¬P) ∧ (¬Q ∨ R ∨ ¬P)} → (¬P ↔ P) (De Morgan's Law)
(Q ∧ S ∧ P) ∨ (¬Q ∧ P) → (¬P ↔ P) (De Morgan's Law)
At this point, the formula ¬P ↔ P is a contradiction. The left side (¬P) states that P is false, while the right side (P) states that P is true. Therefore, the whole statement is always true, regardless of the values of Q, S, and P.
Since the statement is always true, we can conclude ¬(Q ∧ P) ∨ (T ∧ R) is true as well, making the second part of the question valid.
[(T ∨ Q) → (T ∨ S)] ∨ [(T ∨ Q) → (T ∨ S)]
In this statement, we have two identical sub-statements connected by a logical OR operator.
If we assume that (T ∨ Q) → (T ∨ S) is true, then the whole statement is true, regardless of the values of T, Q, and S.
If we assume that (T ∨ Q) → (T ∨ S) is false, then we need to check the other part of the statement.
Assuming (T ∨ Q) → (T ∨ S) is false means that (T ∨ Q) is true, but (T ∨ S) is false. In this case, the second part of the statement [(T ∨ Q) → (T ∨ S)] is true.
Therefore, regardless of the values of T, Q, and S, the whole Valid Statements & Implications is always true.
