Remember to follow PEMDAS, and to only combine terms with like variables.

First, distribute the 2 to all terms within the parenthesis:

2(2p + 4t) = 2(2p) + 2(4t) = 4p + 8t

3 + 4p + 8t, or (D), is your answer choice, for it cannot be simplified anymore.

J.K. Rowling and R.L. Stine are both reading the hunger games. J.K. reads 35 pages every 2 hours and R.L. reads 45 pages every 3

Attention:THIS IS PART B ONLY!

First,find the unit rate.

35/2 and x/1

35 divided by 2 = 17.5 so the unit rate for J.K. is 17.5 pages per hour.

now,R.L.

45/3 and x/1

45 divided by 3 = 15 so the unit rate for R.L. is 15 pages per hour

now we need to divide 355 by 17.5 and divide it by 15.Whichever quotient is smaller,finishes the book first

355 divided by 17.5 = about 20 hrs----J.K.

355 divided by 15 = about 24 hrs-----R.L.

So,who read faster?

If the radius of the base of the cone is 8/3 units and the height is 12 units, what is the volume?

Verdich [7]

Answer:

256/9 * pi units ^3

or approximately

89.3608577021096743 units^3

Step-by-step explanation:

V = 1/3 pi r^2 h

where r is the radius and h is the height

V = 1/3 * pi * (8/3) ^2 * 12

= 1/3 * pi * 64/9 * 12

256/9 * pi units ^3

or approximately

89.3608577021096743 units^3
