Answer:
2388.16 cubic inches
Step-by-step explanation:
Cylinder: 452.16
Rectangular prism: 1936
Answer:
Step-by-step explanation:
56/4=16
P=16+16+12+12=56
A=16*12=192 ft^2
12x+4y=60
3x+y=15. Then y=15-3x
12x+4(15-3x)=60
12x+60-12x=60
0x=0
Then every x and every y is solution.
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
x = −3/2
Decimal Form:
x = −1.5
Mixed Number Form:
x = −1/1/2
Answer:
Option B. ![15/8](https://tex.z-dn.net/?f=15%2F8)
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or ![y=k/x](https://tex.z-dn.net/?f=y%3Dk%2Fx)
step 1
Find the value of k
we have
For ![x=5, y=12](https://tex.z-dn.net/?f=x%3D5%2C%20y%3D12)
substitute
![k=y*x](https://tex.z-dn.net/?f=k%3Dy%2Ax)
![k=12*5=60](https://tex.z-dn.net/?f=k%3D12%2A5%3D60)
The equation is
![y*x=60](https://tex.z-dn.net/?f=y%2Ax%3D60)
step 2
Find the value of x when y=32
substitute the value of y in the equation and solve for x
![y*x=60](https://tex.z-dn.net/?f=y%2Ax%3D60)
![32x=60](https://tex.z-dn.net/?f=32x%3D60)
![x=60/32](https://tex.z-dn.net/?f=x%3D60%2F32)
Simplify
![x=15/8](https://tex.z-dn.net/?f=x%3D15%2F8)
