Find the radius. Round to the nearest tenth.
Arlecino [84]

Answer:

Step-by-step explanation:

V = 1/3 * pi * r^2 * h

r = ?

pi = 3.14

h = 17 cm

3*V = pi * r^2 h = r^2    Divide by pi

3*V/pi = r^2 h  = r^2     Divide by h

3*V/(pi*h)         =r^2      Take the square root of the left to get just  r

sqrt(3*V/(pi*h))  = r         Now solve the equation.

sqrt(3*538.25 /(3.14*17)) = r

sqrt(1614 / 53.38) =

r = sqrt(30.24)

r = 5.493

A chef plans to mix 100% vinegar with Italian dressing. The Italian dressing contains 12%
Hitman42 [59]

Answer:

Amount of  vinegar. 100% : 20 milliliters

Amount of  Italian dressing: 140 milliliters

Step-by-step explanation:

Let's call A the amount of  vinegar. 100%

Let's call B the amount of  Italian dressing . 12% vinegar

The resulting mixture should have 23%  vinegar, and 160 milliliters.

Then we know that the total amount of mixture will be:

A + B = 160

Then the total amount of pure antifreeze in the mixture will be:

A + 0.12B = 0.23 * 160

A + 0.12B = 36.8

Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -1 and add it to the second equation:

-A -B = -160

-A -B = -160

               +

A + 0.12B = 36.8

--------------------------------------

-0.88B = -123.2

B = \frac{-123.2}{-0.88}

B = 140\ milliliters

We substitute the value of B into one of the two equations and solve for A.

A + 140 = 160

A = 20\ milliliters
