The perimeter of a rectangle is 82 meters. If the length of the rectangle is 20 meters more than the width
of the rectangle, find its length and width.

Answers

Answer 1

Answer:

30.5 meters

10.5 meters

Step-by-step explanation:

x = length

y = width

x = y + 20

2x + 2y = 82 (the perimeter of a rectangle)

using the first equation as substitute in the second equation we get

2×(y + 20) + 2y = 82

2y + 40 + 2y = 82

4y = 42

y = 42/4 = 21/2 = 10.5 meters

x = y + 20 = 21/2 + 20 = 21/2 + 40/2 = 61/2 = 30.5 meters

Find the total surface area of this cone leave your answer in terms of pi. 12in 15in

Answers

Total surface area of a cone is given by,

Surface area of the cone = πrl + B

Here, l = Slant height of the cone, r = radius of the circular base and B = Area of the base

   Total surface area of the cone will be 324π in².

From the picture attached,

Slant height 'l' = 15 in.Radius of the circular base 'r' = 12 in.

Substitute these values in the formula of the surface area,

Area of the circular base = πr²

                                          = π(12)²

                                          = 144π in²

Total surface area of the cone = π(12)(15) + 144π

                                                   = 180π + 144π

                                                   = 324π in²  

             Therefore, total surface area of the cone is 324π in².

Miriam is buying popsicles for the after school reading program at the public library. 3 out of 12 popsicles in a carton are red. If Miriam bought 84 popsicles, how many of them are NOT red?


A- 7
B- 21
C- 28
D- 63

Answers

Answer:

D-63

Step-by-step explanation:

This is because we can find the percentage rate for Miriam orignal sales which is 3 poposical out of 12 which are red which means you can put it as 3/12 which is also 0.25 percent if you divide it. Meaning if you times 25% by 84 you will get 21 WHICH IS how much red popsicles there are then you have to subtract cuz they want NOT red.

Which equation represents a line that passes through the points (5,-2) and (8,4)?
A. y= -2x*8

B. y= 1/2x-9/2

C. y=x-6

D. y=2x-12

Answers

Answer:

The correct choice is option D. y = 2x -12

Step-by-step explanation:

slope of the points (5,-2) and (8,4) is m = 2

y — intercept of the points (5,-2) and (8,4) is b = -12

Now, put it all together, and you'll get :  y = 2x -12
