Amy and her fiends have $12. 50 to spend on lunch they agree to share a large fry and buy hamburgers with the rest of the money they use the following inequality to determine how many burgers b they can buy
0. 89b+1. 82<12. 50
Answers
The values of b for which the given inequality will be satisfied are: b = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9 , 10, 11, 12}
The given inequality which shows the status of the purchase by Amy and her friends is,
0.89 b + 1.82 ≤ 12.50
where b is the number of burgers they can purchase.
Solving the given inequality we get,
0.89 b + 1.82 - 1.82 ≤ 12.50 - 1.82 [Subtracting 1.82 from both sides]
0.89 b ≤ 10.68
(0.89 b)/0.89 ≤ 10.68/0.89 [Dividing 0.89 with both sides]
b ≤ 12
since b represents the number of burgers so it cannot be negative or fraction.
So the values for which the inequality will be satisfied are: b = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9 , 10, 11, 12}.

Each pair of polygons is similar. Find each missing side measure. two polygons 12 on top 5 on bottom second polygon 48 on top x on bottom
Answers
Answer:
[tex]x = 20[/tex]
Step-by-step explanation:
Given
First Polygon:
[tex]Top = 12[/tex]
[tex]Bottom =5[/tex]
Second Polygon
[tex]Top = 48[/tex]
[tex]Bottom =x[/tex]
Required
Find x
Since both polygons are similar, then:
[tex]Ratio = Top:Bottom[/tex]
For the first:
[tex]Ratio = 12:5[/tex]
For the second
[tex]Ratio = 48:x[/tex]
Equate both ratios
[tex]12:5 = 48:x[/tex]
Express as fraction
[tex]\frac{12}{5} = \frac{48}{x}[/tex]
Cross Multiply
[tex]12 * x = 48 * 5[/tex]
Solve for x
[tex]x = \frac{48 * 5}{12}[/tex]
[tex]x = \frac{240}{12}[/tex]
[tex]x = 20[/tex]

B. 13 n < 1
C. 3n + 1 >7
D. 3n > 9.5
E. n-2<5
Answers
Answer:
Its just E
I'm sorry if I'm wrong
Answer: A, C, E
Solve for all the inequalitites.
n + 5 < 9
n < 9 - 5
n < 4
∴ n = 3 is a part of the solution set.
13n < 1
n < 1/13
∴ This definitely doesn't include n = 3.
3n + 1 > 7
3n > 6
n > 2
∴ n = 3 is part of the solution because n is larger than 2.
3n > 9.5
n > 9.5 ÷ 3
n > 3.16666666
∴ n = 3 is not part of the solution set.
n - 2 < 5
n < 5 + 2
n < 7
∴ n = 3 is a part of the solution set.

A cell phone costs $750 and loses 28% of its value each year. Write an exponential decay function to represent this situation.
1. f(x)= 750 • 0.72^x
2. f(x)= 0.72 • 750^x
3. f(x)= 750 • 0.28^x
4. f(x)= 0.28 • 750^x
Answers
Answer:
1. [tex]f(x) = 750\cdot 0.72^{x}[/tex]
Step-by-step explanation:
The cell phone experiments an exponential depreciation, which is defined by the following formula:
[tex]f(x) = C_{o}\cdot (1-r)^{x}[/tex], for [tex]0<r< 1[/tex]. (1)
Where:
[tex]C_{o}[/tex] - Initial cost, measured in monetary units.
[tex]r[/tex] - Depreciation rate, no unit.
[tex]x[/tex] - Time, measured in years.
[tex]f(x)[/tex] - Current value of the cell phone, measured in monetary units.
If we know that [tex]C_{o} = \$\,750[/tex] and [tex]r = 0.28[/tex], then the exponential decay function that represents the situation is:
[tex]f(x) = 750\cdot 0.72^{x}[/tex]
Which means that correct answer is 1.

Which statement(s) about the line
below are true? Select all that apply.
A The x-intercept is -8.
B The line has a positive slope.
C The y-intercept is 4.
D The line has a negative slope.
Answers
Answer: A, B, and C.
Step-by-step explanation: The answers you have selected in the picture are correct.
These are the actual claims made regarding the line:
The x-intercept is at - 8 because y = 0 when x = -8.
The line is growing and has a positive slope.
As soon as x = 0 and y = 4, the y-intercept is at 4.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
The true statements about the line are,
The x-intercept is at - 8, as when x = - 8 y = 0.
The line has a positive slope as it is increasing.
The y-intercept is at 4 as when x = 0 y = 4.

which of the given values will make the inequality n-93>175 true?
n=82
n=105
n=268
n=300
n=312
Answers
Answer:
n = 300 and n = 312
Step-by-step explanation:
n - 93 > 175
n > 175 + 93
n > 268
Therefore only the two last answers are are possible n values (n has to be more than 268, not equal)
The two numbers 300 and 312 will make the inequality n-93>175 true which are correct option (D)300 and (E)312.
What is inequality?Inequality is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is not equal.
Given inequality as:
n - 93 > 175
n > 175 + 93
n > 268
Therefore, n must be greater than 268 and not equal.
Hence, the two numbers 300 and 312 will make the inequality n-93>175 true.

Steve studies math for 7/8 of an hour and history for 2/3 of an hour. How many hours did he study?
Answers
Answer:
The answer is 1 13/24 hours or 1 hour, 32.5 minutes
Step-by-step explanation:
Find a common multiple of the denominators 3 and 8, which would be 24. Convert the fractions:
7/8 x 3/3 = 21/24.
2/3 x 8/8 = 16/24
Add the two numerators = 37/24 or 1 13/24.
1/24 of an hour is 2.5 minutes, so 13/24 is 32.5 minutes.
The answer is 1 13/24 hours or 1 hour, 32.5 minutes

the sum of the three terms consecutive terms of an ap is -6 and the product is 64, find the terms. using a, a + d, a + 2d
Answers
Answer:
-8, -2 and 4
Step-by-step explanation:
Let the terms of the AP be a-d, a and a+d
If the sum is 6, then;
a-d+a+a+d = -6
3a = -6
a = -6/3
a = -2
Hence the first term is 6
If the product is 64
(a-d)(a)(a+d) = 64
-2(a²-d²) = 64
-2(4-d²) = 64
4-d² = -64/2
4-d² = -32
-d² = -32-4
-d² = -36
d² = 36
d = 6 or -6
The first term is a-d = -2-6 = -8
second term is a = -2
third term is a+d = -2+6 = 4
Hence the required AP is -8, -2 and 4

x² + 8x + 16 - x² = 6²
