Sara had 88 dollars to spend on 8 books. After buying them she had 16 dollars. How much did each book cost?
Answer
$9
first take $88 and subtract what you have left which is $16,
88-16 = 72
Now take 72 and divide by number of books bought which was 8
72/8 = 9
So each book cost $9

Answer:
a) f(2) = 4
b) g(3) = 3
c) g(1/3) = -1
d) f(3) = 1/2
e) g(-2) = 2
f) f(π) = 3
Step-by-step explanation:
We are given:
f={(2,4),(-4,3),(3,1/2),(π,3)} and g={(3,3),(-2,2),(1/3,-1)}
We need to find the following values of f and g
a) f(2)
f(2) means when x=2, we need to find the value of y.
Looking at the given f={(2,4),(-4,3),(3,1/2),(π,3)} , when x =2 then y=4
So, f(2) = 4
b) g(3)
g(3) means when x=3, we need to find the value of y.
Looking at the given g={(3,3),(-2,2),(1/3,-1)}, when x =3 then y=3
So, g(3) = 3
c) g(1/3)
g(1/3) means when x=1/3, we need to find the value of y.
Looking at the given g={(3,3),(-2,2),(1/3,-1)}, when x =1/3 then y=-1
So, g(3) = -1
d) f(3)
f(3) means when x=3, we need to find the value of y.
Looking at the given f={(2,4),(-4,3),(3,1/2),(π,3)} , when x =3 then y=1/2
So, f(3) = 1/2
e) g(-2)
g(-2) means when x=-2, we need to find the value of y.
Looking at the given g={(3,3),(-2,2),(1/3,-1)}, when x =-2 then y=2
So, g(-2) = 2
f) f(π)
f(π) means when x=π, we need to find the value of y.
Looking at the given f={(2,4),(-4,3),(3,1/2),(π,3)} , when x =π then y=3
So, f(π) = 3

John plays basketball and makes about 60% of the shots he attempts, and misses about 40% of the
shots he makes. Based on this information, if John attempts 150 shots, about how many will he make
in the basket?
The answer is 20%
John make 60% and misses 40%
subtract 60 and 40 and its going to be 20 so 20% of the 150 shots your going to make in the basket.

Apply the distributive property to create an equivalent expression. 6(5x minus 3)
Answer:
30x - 18
Step-by-step explanation:
6(5x - 3)
To distribute, multiply the outside number by everything inside the parentheses.
6 x 5x = 30x
6 x -3 = -18
30x - 18

Translate and solve: Eighty-Two less than r is less than −164.
Give your answer in interval notation.
Answer:
(−∞,−82)
Step-by-step explanation:
Eighty-two less than r, r−82 is less than <−164.
Now we can solve the inequality by adding 82 to each side.
r−82r−82+82r<−164<−164+82<−82
In interval notation, we write this as (−∞,−82).
The value of r in the statement eighty-Two less than r is less than −164
is r < - 82.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
The given statement is Eighty-Two less than r is less than −164 which can be numerically expressed as,
r - 82 < - 164.
r < - 82.

What expressions represent 1/3 times the sum of 8 and 4
Answer:
1/3 * (8 + 4)
Step-by-step explanation:
Expression which represents 1/3 tines the sum of 8 and 4
Expressing mathematically,
Sum of 8 and 4 is written as (8 + 4)
1/3 of the sum is expressed as ; 1/3 x (8 + 4)
Hence,
1/3 * (8 + 4)
1/3 * 12
= 4
Expression is 1/3 * (8 + 4)

A car travels 5/16 of a mile in 1/4 of a minute. How many miles will the car travel in 2 1/4 minutes?
Answer: 2 13/16 miles
Step-by-step explanation:
From the question, we are informed that a car travels 5/16 of a mile in 1/4 of a minute. The number of miles that the car will travel in 2 1/4 minute will be calculated as:
= 5/16 ÷ ( 1/4 / 2 1/4)
= 5/16 × 2 1/4 / 1/4
= 5/16 × (9/4 ÷ 1/4)
= 5/16 × 9
= 45/16
= 2 13/16 miles
The car will travel 2 13/16 miles in 2 1/4 minutes.

9.) In a state with a sales tax of 7%, Hernando
spends a total of $73.98. What is the final price
after tax that Hernando has to pay? Show work.
Answer:
Final price = $79.16
Step-by-step explanation:
Given that:
Sales tax in the state = 7%
Amount spent by Hernando = $73.98
Amount of sales tax = 7% of 73.98
Amount of sales tax = [tex]\frac{7}{100}*73.98[/tex]
Amount of sales tax = 0.07 * 73.98
Amount of sales tax = $5.18
Final price = 73.98 + 5.18 = $79.16
Hence,
Final price = $79.16

If the volume of a box if found by calculating the product of its length, height and width, then which of
the following statements below explain the volume of a box represented by function V(x) = x* (10 -
4x) and correctly interpreted V (2)?
A
Given the length, the height, and the width of the box, it was a perfect cube. V(x) is a cubic
function for volume of the box with sides measuring 2 units, where V(2) = 8.
B
Given the length of x, the height of 2x, and the width of 10 - 4x of the box, V(x) is a cubic
function for the volume of the box, where V (2) = 16.
C Given the length, the height, and the width of the box, 2 of the dimensions were the same. V(2)
is a cubic function for the volume of the box with 2 sides measuring 2 units, where V (2) = 8.

The cycle time for trucks hauling concrete to a highway construction site is uniformly distributed over the interval 40 to 75 minutes. What is the probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes
Answer:
0.8333 = 83.33% probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
Uniformly distributed over the interval 40 to 75 minutes.
This means that [tex]a = 40, b = 75[/tex]
It is known that the cycle time exceeds 45 minutes
This means that we can use [tex]a = 45[/tex]
What is the probability that the cycle time exceeds 50 minutes?
[tex]P(X > 50) = \frac{75 - 50}{75 - 45} = 0.8333[/tex]
0.8333 = 83.33% probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes
