Answer:
A. see below
B. 500 yearbooks
C. 1562 yearbooks
D. $13,100
Step-by-step explanation:
A. The first term (7500) is probably a flat fee for the production of yearbooks. No matter how many yearbooks you will always have to pay that amount. The second term (8n) is the cost of each individual yearbook.
B. For this problem you need to use the equation. Since the number given to us is an amount of money, it will go into the variable C. Solve for n.
C = 7500 + 8n
11,500 = 7500 + 8n
4,000 = 8n
500 = n
You can purchase 500 yearbooks.
C. For this problem, the amount is again in dollars so it will go into the variable C. Solve for n.
C = 7500 + 8n
20,000 = 7500 + 8n
12,500 = 8n
n = 1,562.5
Since the number is not a whole number, round down. You can purchase 1562 yearbooks.
D. For this problem, the given value is not in dollars so the value will go into n. Solve for C.
C = 7500 + 8n
C = 7500 + 8(700)
C = 7500 + 5600
C = 13,100
The cost of 700 yearbooks would be $13,100.
Answer:
No
Step-by-step explanation: By dividing 12/98 you would get a decimal(0.12244897959) by this not being a whole number it can not be a perfect square.
Answer:
y = 3
Step-by-step explanation:
y = k/x
xy = k
3 × 8 = k
k = 24
x = 8
y = 24/x
y = 24/8
y = 3
The volume of the rectangular prism can be express in standard polynomial as follows:
x³ + 12x² + 35x
<h3>How to find the volume of a rectangular prism?</h3>
volume of a rectangular prism = lwh
where
- l = length
- w = width
- h = height
Therefore,
let
height = x
width = x + 5
length = x + 5 + 2 = x + 7
Therefore,
volume = x(x + 5)(x + 7)
volume = x(x² + 7x + 5x + 35)
volume = x(x² + 12x + 35)
volume = x³ + 12x² + 35x
