The denominator of a fractional exponent represents the degree of root.

For example

x^{\frac{1}{3}} = \sqrt[3]{x}\\x^{\frac{1}{4}} = \sqrt[4]{x}\\x^{\frac{1}{5}} = \sqrt[5]{x}

Find the missing height
Eva8 [605]

Answer:

h = 39.8 inches

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2h

We know the diameter d = 32 so the radius is 1/2 of the diameter

r = d/2=32/2 = 16

32000 = pi (16)^2 h

32000 = 256 ( pi) h

Divide each side by 256 pi

32000 / 256 pi = h

125/pi = h

Using 3.14 for pi

39.8089172 = h

Rounding to the nearest tenth

h = 39.8 inches

Solve this system for brainliest answer!!!<br><br> 3.75x+4y=2,160<br> x+y=550
djyliett [7]
First solve the second equation to equal x.

x + y = 550

Subtract y from both sides.

x = 550 - y

Put this into the first equation in place of x.

3.75 (550 - y) + 4y = 2160

Multiply everything in the parenthesis by 3.75

2062.5 - 3.75y + 4y = 2160

Combine like terms.

2062.5 + 0.25y = 2160

Subtract 2062.5 from both sides.

0.25y = 97.5

Divide 0.25 on both sides.

y = 390

Put this into the second equation in place of y.

x + 390 = 550

Subtract 390 from both sides.

x = 160

So x = 160 and y = 390

Hope this helps!
