Answer:
first blank: c(x) = 45x + 14
second blank: 7
Step-by-step explanation:
explanation for second blank:
set up the equation equal to 329:
45x + 14 = 329
subtract 14 from both sides:
45x = 315
divide by 45 to leave x alone:
x = 7

Answer:
The total cost of the cylindrical tank is $226.28
Step-by-step explanation:
Dimensions of the tank are: radius = 3 ft , height = 2 ft
Cost per cubic foot = $4
Now, total volume of the cylindrical tank = 
Here, take π = 22/7
So, Volume = 
So, the <u>volume of the tank = 56.57 cubic feet. </u>
Now, cost per cubic foot = $4
Hence, the total cost of the tank = Total Volume of the tank x cost per foot
= 56.57 x 4 = $226.28
So, the total cost of the cylindrical tank is $226.28
The answer is Between 12 and 26
Answer:
Length = 18 in
Width = 15 in
Step-by-step explanation:
We have that the area of a rectangle is:
A = L * W
but L = 1.2 * W
A = 1.2 * (W ^ 2)
1.2 * (W ^ 2) = 270
(W ^ 2) = 270 / 1.2
W ^ 2 = 225
Therefore, W is equal to:
W = 225 ^ (1/2)
W = +/- 15, but only +15 makes sense
W = 15
Now for L:
L = 1.2 * 15
L = 18
A = 15 * 18 = 270 in ^ 2
That would be 9/4
Or in mixed number form: 2 1/4
I hope this helps! (:
