Answer:
The formula to get the rate R would be:
principal x (1+R)^time = (principle + interest)
=> 3890 x (1 + R)^4 = 5908
=> (1 + R)^4 = 5908/3890
=> (1 + R)^4 = 1.5188
=> 1 + R = 1.11
=> R = 1.11 - 1 = 0.11 = 11%
Hope this helps!

Answer:
x=8
Step-by-step explanation:
Because you are solving for x, you want to cancel out the y terms. You can do this by multiplying the entire equations by numbers that will make the y terms have equal numbers but opposite signs.
2(2x-5y=1)
5(-3x+2y=-18)
This turns into
4x-10y=2
-15x+10y=-90
The y terms cancel out, and the other terms can be added together.
-11x=-88
x=8
To find the volume of any cube you need to know the length, width and height. The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times.
About 27.5 percent so B is the correct answer
