Answer:It will be 80 cubic centimeters

Step-by-step explanation:The coin is in a shape of a cylinder and the formula for the shape of a cylinder is volume=radius^2 times height, you can enter your values of radius=1 because radius is half of the diameter and height=0.5. Thus your answer for 1 coin is 1.571 and you multiply that times 50 because you want to make 50 coins and you get 78.55 cubic centimeters. Then you need it to be a multiple of 10 so 78.55 is closer  to 80 than 70.

Solve the following system of equations using Substitution: Submit your answer as an ordered pair. 2x−3y=32x-3y=32x−3y=3 x=y+2x=
exis [7]

9514 1404 393

Answer:

  (3, 1)

Step-by-step explanation:

We assume you want the solution to the system ...

  • 2x−3y=3
  • x=y+2

The second equation gives a nice expression for x, so we can use that in the first equation.

  2(y+2) -3y = 3 . . . . substitute for x in the first equation

  2y +4 -3y = 3 . . . . . eliminate parentheses

  -y = -1 . . . . . . . . . . . collect terms, subtract 4

  y = 1 . . . . . . . . . . . . multiply by -1

  x = 1 +2 = 3 . . . . . . substitute for y in the second equation

The solution is (x, y) = (3, 1).

Yolanda made $192 for 12 hours of work. At the same rate, how many hours would she have to work to make $272?​
denpristay [2]

Answer:

17 hours

take $192 and divide it by 12 so you know how much they make per hour

$192 / 12 = 16

then you're going to take $272 and divide it by what you know now - how much they make per hour (this will get you how many hours they worked)

$272 / 16 = 17
