There are three 'x's on the 3/4 spot, so you know that there are three 3/4 inch buttons.

To find how long they are lined up, you add them.

3/4 + 3/4 + 3/4 = 9/4

9/4
as a mixed number is 2 1/4.

Good luck!

This pencil cup is made out of plastic. It is 5 inches tall and has a radius of 1.75 inches. How many square inches of plastic w
Dmitry [639]

Answer:

To make the cup 64.57 square inches of plastic were used.

Step-by-step explanation:

A cup has the format of a cylinder with a open top. The surface area of the cup is given by the area of it's base (a circle) and the area of it's walls, wich can be seen as rectangle where the width is the length of the circle at the base and the height is the height of the cylinder. So we have:

area of the base = pi*r^2 = 3.14*(1.75)^2 = 3.14*3.0625 = 9.616 square inches

area of the walls = 2*pi*r*h = 2*3.14*(1.75)*5 = 54.95 square inches

surface area of the cup = area of the base + area of the walls = 9.616 + 54.95

surface area of the cup = 64.57 square inches

To make the cup 64.57 square inches of plastic were used.

Please answer this math question.
Elenna [48]

Answer:

C

Step-by-step explanation:

The technical probability of rolling any number on a standard die is 1/6 because there's six numbers. Based on that, since he rolled a "4" on 5 tosses, it seems likely that it's 30 times, because 1/6 of 30 is 5. I haven't done probability in awhile but if I remember correctly that should be right

HELP ASAP
Mamont248 [21]

Answer:

m = 0

Step-by-step explanation:

distribute

7 + 35m + 2m = 7 +2m

add 35m + 2m

7 + 37m = 7 + 2m

subtract 2 from 37m

7 + 35m = 7

subtract 7 from 7

35m = 0

0 ÷ 35 = 0

so technically the answer is 0

I'm not 100% sure but I do believe this is right
