Answer:

1.62 yards

Step-by-step explanation:

\(\frac{65}{3} =21.666666\)

\(\frac{100}{21.6} = roughly 4.62\)

This means that there are 4.62 yards in the final product.

The pink fabric is \(4.62-3=1.62\) yards.

Answer: Yes

Step-by-step explanation:

Since she wants to run the route 40 times we have to multiply the 220 yd route with how many times she wants to run it

40 x 220 = 8800 which is 5 miles

She reaches her goal and beyond that

Step-by-step explanation:

Answer:

216π cubic units

Step-by-step explanation:

volume of a cone = πr²h/3

r = radius = 1/2 of diameter = 1/2 of 18 = 9

volume = π*9²*8/3 = 216π

The volume of the cone with a diameter of 18 units and a height of 8 units is

216π cubic units.

Option B is the correct answer.

It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.

The volume of a cone is 1/3πr²h.

We have,

Diameter = 18 units

Radius = 9 units

Height = 8 units

The volume of a cone.

= 1/3 π r² h

= 1/3 x π x 9² x 8

= 1/3 x π x 81 x 8

= 27 x π x 8

= 216π cubic units.

Thus,

The volume of the cone is 216π cubic units.

Answer:

A.

To express 1/2% as a decimal, you divide 1/2 by 100. You can use a fraction bar or a slash to indicate division. Like this:

1/2 ÷ 100 = 0.005

or

1/2 / 100 = 0.005

B.

To find the length that the planks are allowed to vary, you multiply the decimal value of 1/2% by the intended length of 8 feet. Like this:

0.005 · 8 = 0.04 foot

C.

To find the shortest and longest allowable planks, you subtract and add the variation length from and to the intended length of 8 feet. Like this:

Shortest: 8 - 0.04 = 7.96 feet

Longest: 8 + 0.04 = 8.04 feet

If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Step-by-step explanation:

ist you have to lind the lcd of each fraction. that would be 10.

1/2x5/5=5/10 of the boys have brown eyes

1/5x2/2=2/10 of the boys have blue eyes

3/10=3/10 of the boys have hazel eyes

The question is asking to see how many more boys have brown eyes than hazel eyes.

Subtract 3/10 from 5/10

and that gives you 2/10

The answer is 1/5.

We know that half of the boys in Jason's class has brown eyes, while three-tenths of the boys in his class have hazel eyes. Therefore, if we subtract the two values, you should get your answer.

\(\frac{1}{2} -\frac{3}{10} =\frac{2}{10}\)

1/5 is the simplified version of 2/10. Therefore, 1/5 is your answer.

The percentage change from 0.79 to 1.00 is 26.58 % increase

Step-by-step explanation:

((1.00 - 0.79) / 0.79) * 100 = 26.58%

Answer:

26.58% Increase

Step-by-step explanation:

Using the formula %Increase=100×final-initial/initial

%Increase=100×1-0.79/0.79=26.58%

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

⬇️—Answer—⬇️

60 flowers in Chef Morgan’s Restaurant.

⬇️—Solutions (with-steps)—⬇️

We are given the following information :

1) The restaurant has 24 tables.

2) 15 of those tables have 1 flower in each vase.

3) The remaining have 5 flowers

15 of her tables + her remaining tables = 24 of her total tables.

This means, 15 of her tables have one flower in each vase while she has 9 tables which are remaining containing 5 flowers in their vases.

In mathematics each usually means to multiply something. So,

15 x 1 = 15

9 x 5 = 45

15 + 45 = 60

So, there are 60 flowers in total.

To check our answer:

(15 x 1) + (9x5) = 60

Answer:

  1108 in²

Step-by-step explanation:

You want the total surface area of the pentagonal prism shown.

The area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...

  A = LW +1/2bh

  A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches

The lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.

  LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches

The total surface area of the figure is the sum of the two base areas and the lateral area:

  SA = 2(114 in²) +880 in² = 1108 in²

The surface area of the composite figure is 1108 in².
