1.) 7+7/9x=−42 2.) 4x+1=−15 3.)−4(x−3)=−40

Answers

Answer 1

Answer:

1) x= -1/27

2) x=-4

3) x=13

Step-by-step explanation:

1) 7+7/9x= = -42

   14/9x= = -42

  14/9x X 9x= -42 X 9x

    14= -378x

    -378x= 14

   -378x/-378= 14/-378

      x= -1/27

2) 4x+1=−15

 4x+1-1=-15-1

    4x=-16

   4x/4= -16/4

      x=-4

3) −4(x−3)=−40

 -4(x-3)/-4= -40/4

     x-3=10

   x-3+3=10+3

        x=13

Step-by-step explanation:

There are many cones with a height of 12 inches. Let r represent the radius and V
represent the volume of these cones.

Plot points that show the volume when r=1, r=2, r=3, and .r=4.

HELP!

Answers

Answer:

If R = 1, ~12.57 is the y. (r is the x.)

If R = 2, ~50.27

If r = 3, ~113.1

If r = 4, ~201.06

Step-by-step explanation:

The formula of a cone is pi * r^2 * h/3

If r = 1, we have pi * 1^2 * 12/3

12/3 = 4

and 1^2 = 1

pi * 1 * 4

4 * pi = ~12.57

if r  = 2, we have an imrpoved formula,

pi*2^2 * 4  (h/3 became 4 since 12/3 = 4)

2^2 = 4

4*4 = 16

pi * 16 = ~50.27

If r = 3

our formula is pi*3^2*4

3^2 = 9

pi*9*4

9*4 = 36

36* pi = ~113.1

If r = 4,

our formula is

pi*4^2*4

4^2 = 16 and 16*4 = 64

pi*64 = ~201.06.

Answer:

If R = 1, ~12.57 is the y. (r is the x.)

If R = 2, ~50.27

If r = 3, ~113.1

If r = 4, ~201.06

find surface area of the prism pls!!!!! explain too. I really need help!!!

Answers

i believe you have to multiply meaning 6x5x2 it’s 60.

Answer: 104 square inches

Step-by-step explanation:

The surface area of a prism is the sum of the surface are of all of it's faces.

We can turn that into this equation SA =  2(w x l) + 2(l x h) + 2(w x h) where w is width, l is length, h is height, and 2(w x l) is the top and the bottom surface areas, 2(l x h) is the left and right sides, and 2(w x h) is the front and back.

Substitute to get this:  SA =  2(6 x 2) + 2(2 x 5) + 2(6 x 5)

Simplify with multiplication to get this: SA = 24 + 20 + 60

Simplify with addition to get this: SA = 104

Add the unit label and you get 104 square inches.
