Answer:
The amount it will cost to paint both containers is $240
Step-by-step explanation:
The dimensions of the containers are
Length, L = 40 ft
Width, W = 8 ft and
Height, H = 9 ft
Therefore, the surface area, SA of the containers is given by
SA = 2·L·W + 2·L·H + 2·W·H
40 × 8 × 2 + 40 × 9 × 2 + 2 × 9 × 8 = 1,504 ft²
Therefore, the number of cans of paints required is given by;
= 8 Cans
One can of paint costs $15, therefore, 8 cans costs ;
$15 × 8 = $120.
Since there are two storage containers, the total cost of painting is given by;
Total cost to paint both containers = 2 × $120 = $240.
Answer:
Minimum number of pennies = 10
Step-by-step explanation:
Given:
Maximum number of coins Hannah have = 25
Total number of of nickels (coins) she has = 11
Total value of the combined coins = $ 0.65
We have to find the minimum number of pennies.
Let the number of pennies be "p" and no. of nickels be "n".
Note:
Value of 1 penny = $ 0.01
Value of 1 nickel = $ 0.05
Arranging the above situation in terms of equations:
According to their quantities.
⇒ and
so
According to their values.

⇒
Minimum number of pennies :
⇒ which also satisfies
Therefore :
⇒
Plugging p= 10 we can verify the values.
⇒
⇒
⇒
So,
Minimum number of pennies Hannah have = 10
