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.

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.

Find x+y

Answers

Answer:

62

Step-by-step explanation:

2y-5 and 95 are vertical angles so they are equal

[tex]2y - 5 = 95[/tex]

[tex]2y = 100[/tex]

[tex]y = 50[/tex]

3x and 144 form a linear pair angle so

[tex]3x + 144 = 180[/tex]

[tex]3x = 36[/tex]

[tex]x = 12[/tex]

x=12 and y=50 so

[tex]12 + 50 = 62[/tex]

Answer:

x + y = 62

Step-by-step explanation:

To find x + y we first need to find the value of x and y separately

first to find x

3x + 144 = 180 (linear pair property used)

3x = 180 -144

3x = 36

x = 36/3

x = 12

Now we need to find the value of y

2y - 5 = 95 (vertically opposite angles are equal)

2y = 95 +5

2y = 100

y = 100/2

y = 50

Now they are asking to add

x + y = ?

12 + 50

= 62

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
