Answer:$9.16

Step-by-step explanation:

What I did was 20% of $45.80!  If you have a tip or a percent problem you can think of it as that percent of the certain number.  In math "of" means mupltiply.

Punch in your calculator .2 which is 20% times 45.8 and you get your answer $9.16.  

Hope this helps bwo

Kruka [31]

Answer:

67 square units

Step-by-step explanation:

Circumference/pi = diameter

29/3.14 = 9.24

Radius = 9.24/2 = 4.62

A = pi * r^2

A = 3.14 * 4.62^2 = 67 square units

HI! I HAVE A TEST ON MONDAY AND IM TRYING TO STUDY, IM KINDA STUCK ON HOW TO DO THIS PROBLEM..
sergij07 [2.7K]

Answer: See below

Step-by-step explanation:

number of yellow pieces/number of blue pieces

= 14/24

= 7/12 --> 7 to 12 --> 7:12

The ratio that represents the number of yellow pieces to the total number of pieces is part-to-whole

number of yellow pieces/total number of pieces

= 14/100

= 7/50 --> 7 to 50 --> 7:50

The ratio that represents the number of blue pieces to the total number of pieces is part-to-whole

= 24/100

= 6/25 --> 6 to 25 --> 6:25

HELP ME PLESA IM DESPO PAKJDCD PLS HELP
WARRIOR [948]

Answer:

144 cm²

Step-by-step explanation:

A prism's surface has 2 triangles & 3 rectangles.

In both the triangles , length of :

Perpendicular = 4 cm

Base = 6 cm

So , Area of both triangles = 2(\frac{1}{2} * Base * Perpendicular) = 2(\frac{1}{2}* 6 * 4) = 24 cm^2

In the 3 rectangles ,

Length = 8 cm

Width = 5 cm

So , Area of the rectangles = 3( Length * Width) = 3(8 * 5) = 120 cm^2

Hence the total surface area of the prism is = 120 + 24 =144 cm²

Answer:

2.  92 ounces of Sprite

3.  1/6 do not want mustard on their ham sandwiches

4.  6 hours playing volleyball

5. 32 portions

Step-by-step explanation:

2.  Sam has 8 cans of Sprite.  Each can is 11 2/4 ounces

We can simplify 2/4 to 1/2

Multiply the number of cans by  the ounces per can

8 * 11  1/2

8 * 11.5

92 ounces

3.  1/2 of the students want ham.  1/3 of those do not want mustard

We multiply 1/2*1/3 = 1/6

1/6 of the students do not want mustard on their ham sandwiches

4.  8 hours at the beach.  3/4 of the time was spent playing volleyball

Multiply this together

8*3/4 = 8/4*3 = 2*3 = 6 hours

5.  We have 4 lbs of wings.  We divide it into 1/8 lbs parts

4 ÷ 1/8

Copy dot flip

4 * 8/1

32 portions
