10 meters, because 25 percent of 8 is 2, 2 plus 8 is 10.
If each face has an area of 4 than the side lengths are 2, because area is b•h and 2•2 is 4. Now, volume is length•width•height. All of these will be two because sides are the same in a cube. 2•2•2 is 8, which is your answer
Answer:
&
Step-by-step explanation:
Column 1:
500 x 5% = 250
$250 in interest each year
Column 2:
500 + 250 = 750
<em>$750 at the end.</em>
Answer:
2^60.
Step-by-step explanation:
You can do this using deMoivres theorem.
First convert to Polar form:
(-1+i(root 3))^60
r = √((-1)^2 + (√3)^2)
= √(1 + 3)
= 2.
So sin Ф = √3/2
Ф = 2π/3 - as the angle is in the second quadrant ( real part is -1)
So in polar form we have:
[2(cos2π/3 + i sin2π/3 )]^60
Bu de Moivres theorem this is
2^60(cos2π/3* 60 + i sin2π/3* 60)
= 2^60(cos(120π/3) + i sin(120π/3)
= 2^60(cos40π + i sin 40π)
= 2^60(1 + i*0)
= 2^60.
Answer:
x=6
Step-by-step explanation:
First, combine like terms. 3x + 2x = 5x. Now, your equation should look like this: 5x -5 = 25. Next, add 5 to both sides to get this: 5x = 30. Finally, divide both sides by 5 to get x=6. So, 6 equals 6
