170 out of 300 students in the school own a dog.

A word problem is a short passage presenting a "real-life" situation where an issue has to be solved using math.

Word problems are seen as an essential component of learning in the elementary curriculum because they require students to apply their understanding of various concepts to situations that are representative of "real-life" situations.

Given that,

Total number of students surveyed = 30

Total number of students that own a dog = 17

Total number of students in the school = 300

In order to find the equivalent of 17/30 with the bottom number 300

we get, 10 times of 30 is equal to 300 so based on this,

17/30 times 10/10 = 170/300

Thus, 170 out of 300 students in the school own a dog.

Correct question: Out of 30 students surveyed, 17 have a dog. Based on these results, predict how many of the 300 students in the school have a dog.

The angle that the golfer has between the spectator and the hole is cos^-1((a^2 + b^2 - c^2)/(2ab))

The angle that the golfer has between the spectator and the hole can be found using the Law of Cosines. The Law of Cosines states that for a triangle with sides a, b, and c and angle C opposite side c, the following equation holds:

c^2 = a^2 + b^2 - 2ab * cos(C)

In this case, we know that a = 140 (the distance from the golfer to the spectator), b = 200 (the distance from the golfer to the hole), and C = 120 (the angle between the golfer and the spectator).

We can use these values to solve for c, which is the distance from the spectator to the hole. Once we have this value, we can use the Law of Cosines again to find the angle between the golfer and the hole.

c^2 = 140^2 + 200^2 - 2 * 140 * 200 * cos(120)

c = sqrt(140^2 + 200^2 - 2 * 140 * 200 * cos(120))

Now we can use this value of c to find angle A:

A = cos^-1((a^2 + b^2 - c^2)/(2ab))

Note that the angle A is what we're looking for, the angle between the golfer and the hole.

Therefore ,when the problem of expression is solved, we may state that the necessary inequality statement is 4.50x+1.75y 50.

An expression in mathematics consists of a statement, two or more variables or integers, but one or more mathematical functions. Numbers can be multiplied, divided, added, or subtracted using this mathematical operation. The construction of an expression is as follows: Expression: Math operator, variable or number, and math operator.

In mathematics, an inequality is a linear connection or a collection of numbers even when there is no equal sign. Equity always comes after equilibrium. When two numbers are not equal, inequality exists. Between equality and inequality, there exist differences. The most common symbol was chosen because when parameters aren't the same or comparable (). Values can be compared using a variety of disparities, no matter how few or numerous they are. Many fundamental inequality problems can be addressed by flipping the two aspects until only the variables are left

Is the relation a function: C. No, because for each input there is not exactly one output.

In Mathematics, a function is typically used for uniquely mapping an independent value (input variable or domain) to a dependent value (range or output variable).

This ultimately implies that, an independent value represents the value on the x-axis of a cartesian coordinate while a dependent value represents the value on the y-axis of a cartesian coordinate.

Since the independent value (12) is mapped to multiple dependent values (-4 and -2), we can logically deduce that the relation does not represent a function.

plug the two points [tex](x_{1},y_{1} )=(-6,-4) and (x_{2} ,y_{2} )=(-5,-4)[/tex] into the equation.

[tex]y-y_{1}=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}*(x-x_{1} )\\y+4=\frac{-4-(-4)}{-5-(-6)} *(x+6)[/tex]

[tex]y-y_{1}=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}*(x-x_{1} )\\y+4=\frac{-4-(-4)}{-5-(-6)} *(x+6)\\y+4=0\\y=-4[/tex]

The equation of line that runs through the points (-6, -4) and (-5, -4) is y = -4.

The slope-intercept form is expresses as;

y = mx + b

Where m is slope and b is y-intercept.

Given that the line that passes through the points (-6, -4) and (-5, -4).

First, we find the slope.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( -4 - (-4) )/( -5 - (-6) )

Slope m = ( -4 + 4 )/( -5 + 6 )

Slope m = ( 0 )/( 1 )

Slope m = 0

Next, find the y-intercept b.

y = mx + b

Plug in slope m = = and point 1( -6, -4 )

-4 = 0(-6) + b

Solve for b

-4 =  b

b = -4

Now, plug slope m = 0 and y-intercept b = -4 into the slope intercept form to determine the equation of the line.

y = mx + b

y = 0(x) + -4

y = -4

Therefore, the equation of line is y = -4.

The x-value of where the beam should be placed is X = (x1+x2)/2.

Given: the distance between the two trusses is 2 feet and the reinforcement beam will extend from one truss to the other.

We can set up an equation using the distance formula to determine the x-value of where the beam should be placed.

The distance formula is: d = √((x2 - x1)² + (y2 - y1)²)

Let's assume that the trusses are located at point (x1, y1) and (x2, y2) and the beam is located at point (x, y).

We know that the distance between the trusses is 2 feet, so we can set d = 2.

We can use the coordinates of the trusses and the point where the beam is located to set up the equation:

d = √((x2 - x1)² + (y2 - y1)²) = 2

Since the trusses are located on the same line and only the x-coordinate changes, we can assume that y1=y2

Therefore the equation can be simplified to √((x2 - x1)²) = 2

Square both sides: (x2 - x1)² = 4

x2 - x1 = 2

Now we know that the difference between the x-coordinates of the two trusses is 2 feet.

So, to find the x-value of the point where the reinforcement beam should be placed, we can take the average of the x-coordinates of the two trusses.

x = (x1+x2)/2

We don't know the values of x1 and x2, so we can't solve for x. But we know that the reinforcement beam should be placed exactly in the middle of the trusses.

Thus, The x-value of where the beam should be placed is X = (x1+x2)/2.

Answer:

the reduced price must be increased by 32% to have a 12% higher price than the original price

The percentage that must the reduced in the reduced price so that the new price is 12% higher than the original price is 40%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Let the price of the suit = 100

Reduced = 20%

Now,

The reduced price of the suit.

= 100 - (20% of 100)

= 100 - (20/100 x 100)

= 100 - 20

= 80 _____(1)

Now,

New price.

= 100 + (12% of 100)

= 100 + 12

= 112

Now,

From (1)

100% = 80

Multiply 112/80 on both sides.

112/80 x 100% = 112

140% = 112

This means,

40% increased

The measure of angle S = 29 degrees, angle T= 29 degrees, and angle U = 122 degrees.

A triangle is a straightforward closed curve made up of three-line segments. An angle inside the form is known as an interior angle. The inner angles add up to a constant 180 degrees.

The sum of internal angle of the triangle is 180 degrees.

(x + 4) + (x + 4) + (5x - 3) = 180

7x + 5 = 180

7x = 175

x = 25

Substitute the value of x in each of the angle to find the measure of each angle as follows:

The value of angle S = x + 4 = 25 + 4 = 29 degrees.

The value of angle T = x + 4 = 25 + 4 = 29 degrees.

The value of angle U = 5x - 3 = 125 - 3= 122 degrees.

Hence, the measure of angle S = 29 degrees, angle T= 29 degrees, and angle U = 122 degrees.

For the number -(4 / 7), the additive inverse would be (4 / 7).

The additive inverse of a number is the number that when added to the original number, the result is 0. In other words, it is the opposite of the original number.

To see this, let's add -(4 / 7) and (4 / 7) together:

-(4 / 7) + (4 / 7) = 0

This is because the negative sign in front of the fraction indicates that the fraction is the opposite of (4 / 7). So adding the two fractions together cancels out the opposite and results in 0.
