The volume of the rectangular prism can be found with the formula
v= length × width × height
V = 10×10×30 = 3000
the volume of the triangular prism can be found with
v = 1/2(base×width×height)
v=1/2×30×9×10 = 1/2×2700
v = 1350
Now add the two volumes together for the total volume...
3000+1350 = 4,350 in^3

Answer:
$504
Step-by-step explanation:
since there is 12 months in a year , the family would pay 12$ a year.
12x12= 144
then since they paid a down payment of $360
360+144=504
so they would have paid $504
Answer:
![y(x) = 0.0732x + 17.32](https://tex.z-dn.net/?f=y%28x%29%20%3D%200.0732x%20%2B%2017.32)
Step-by-step explanation:
The equation for the monthly charge has the following format
![y(x) = ax + b](https://tex.z-dn.net/?f=y%28x%29%20%3D%20ax%20%2B%20b)
In which y(x) is the cost in function of the number of kilowatt-hours used(x), a is the price of each killowatt hour and b is the fixed(base) charge.
Base charge of $17.32 per month.
This means that ![b = 17.32](https://tex.z-dn.net/?f=b%20%3D%2017.32)
charge of 7.32 cents per kilowatt-hour
Our answer is in dollars. Each dollar is 100 cents. So 7.32 cents is ![a = 0.0732](https://tex.z-dn.net/?f=a%20%3D%200.0732)
Write an equation for the monthly charge y in terms of x, the number of kilowatt-hours used.
![y(x) = ax + b](https://tex.z-dn.net/?f=y%28x%29%20%3D%20ax%20%2B%20b)
![y(x) = 0.0732x + 17.32](https://tex.z-dn.net/?f=y%28x%29%20%3D%200.0732x%20%2B%2017.32)
