miskamm [114]

Answer:

The answer to your question is r = 4 in

Step-by-step explanation:

Data

Volume = 4000 π in³

height = 250 in

radius = ?

Process

1.- Look the formula to calculate the volume of a cylinder

        Volume = πr²h

2.- Solve for r²

         r² = Volume / πh

3.- Substitution

         r² = 4000π / π(250)

4.- Simplification

         r² = 16

         r = √16

5.- Result

         r = 4 in

Find the solution to the following system using substitution or elimination: y = 3x + 2 y = -2x - 8 O A. (-5,-) OB. (-2,-4) O C.
mr Goodwill [35]

Answer:

B. (-2,-4)

Explanation

Given equations:

   y = 3x + 2

   y = -2x - 8

Solving both equations will yield the values of x and y;

Solution:

   y = 3x + 2    ----- (i)

   y = -2x - 8   ------ (ii)

Using substitution method, input equation i, into ii

    3x + 2 = -2x - 8

Collect like terms and solve;

     3x + 2x = -8 -2

         5x  = -10

            x  = -2

Then put x = -2 into i, to find y

      y = (-2 x 3) + 2

       y = -6 + 2 = -4

So, the solution of the equation is B. (-2,-4)

What is this ?????? plz helpppp
gogolik [260]

Answer:

The baker uses 15 cups of cereal for 10 cups of marshmallows

Step-by-step explanation:

The proportion 6:4 has to stay true in the answer, so both numbers have to be multiplied by the same number

6 x 2.5 = 15

4 x 2.5 = 15

both numbers were multiplied by the same number in this answer and it is the only answer that stays true to the ratio

Solve the proportion. Show your work.
Oxana [17]
3/x+1=5/11 first cross multiply 
3*11=33 and 5*x+1= 5x+5          5x+5=33 
then subtract 5 on both sides 5x+5-5=33-5 
5x=28 so divide 5 on both sides 
5x/5=28/5 
x= 5.6
Hope I Helped
