Which expression equals 6 when a = 5 and b = 1/3?

Step-by-step explanation:

The given choices are

A) 9b^2 + 3a - 10

B) a^2 - 20 - 3b

C) 3(a - 2) - a + a 6b

D) 9b + ab

Now, we need to evaluate each expression and see which one gives 6 as result.

We know that and

A)

Choice A is part of the right answer, because is equal to 6.

B)

Choice B is not part of the right answer.

C)

Choice C is not part of the answer.

D)

Therefore, the only expression which is equal to 6 when a = 5 and b = 1/3 is choice A.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
