Answer:

The estimated number of children who attended the parade is 6,336.

Step-by-step explanation:

Since the route for Millburn's Fourth of July parade stretches 2 miles (10,560 feet), and spectators are usually evenly distributed along both sides of the route, and along one side of 50 feet of the route, you count 15 children, to estimate the number of children who attended the parade, the following calculation must be performed:

(10,560 / 50) = 211.2

211.2 x 15 x 2 = X

211.2 x 30 = X

6.336 = X

Therefore, the estimated number of children who attended the parade is 6,336.

Answer:

You are right. It's 56

Step-by-step explanation:

You do half of the solid (4*7) with is 28. Then because it is only half you would double your answer to get 56.

V = L * W

V = 4 * 7

V = 28

Then double it.  28 * 2 = 56

Answer:

301.4 ft.

Step-by-step explanation:

The radius of this circle is 4; the height of this circle is 6.

Using the formula, πr²h, we can plug-in the unknown values.

In the formula, 'r' means radius, 'h' means height, 'π' means pi. 3.14 is often a substitute for pi.

πr²h - π4² · 6 = 301.44.

301.44 rounded to the nearest tenth is 301.4.

Therefore, the volume of this cylinder is 301.4 ft.

Step-by-step explanation:

Answer:

R = 12

L = 84

Step-by-step explanation:

R + L =96

L = 7R

R = 1R

L = 7R

1 R + 7R = 8R

R = 12

L = 84

Answer:

so the answer is about 8.40

Steps

--------------------------------------------------------------------------------------------------------------

find the number in the tenth place and look one place to the right for the rounding digit. Round up if the number is greater than or equal to 5 but since 2 is less than 5, stays the same

16.820⇒16.82

--------------------------------------------------------------------------------------------------------------

8.264⇒8.364

Remember round up if the number is greater than or equal to 5 and round down if the number is less than 5.

--------------------------------------------------------------------------------------------------------------

now that we have rounded everything. It is time to estimate 16.82-8.364.

16.82 is close to 16.80 and 8.364 is close to 8.40.

16.80-8.40=8.40

Answer:

D. 116 square cm

Step-by-step explanation:

This is because the formula to find the area of a triangle is h(b/2). 15 divided by 2 is 7.5 and 7.5 multiplied by 4 is 30. The square's area is 16 and the parallelogram  70. 70 + 30 + 16 = 116.

Answer:

176 i think seeing as area is multiplication

Step-by-step explanation:

Answer:

Solution given;

AB=16ft

AD=11ft

Area of triangle=½(11*16)=88ft²

Since it is pentagon

it has 5similar triangle

Area of pentagon=5×88ft²=440ft²

440ft² is a required area.

Answer:

1. x = 67.5

2. x = 2.5

3. x = 35.2

4. x = 2.0

5. x = 17.0

Step-by-step explanation:

Question 1

The proportion is set up in the form x/9 = 15/2. Multiply both sides by two to get rid of the two in the denominator on the right side. After doing so, multiply by 9 on both sides to get rid of the 9 in the denominator on the left:

2x/9 = 15

2x = 9(15)

Next solve for x:

2x = 135

x = 67.5

Question 2

The proportion is set up in the form 20/8.7 = 5.8/x. Multiply both sides by the second denominator, x, and then both sides by the first, 8.7. This will leave you with the work below:

20x/8.7 = 5.8

20x = 8.7(5.8)

Next, solve for x:

20x = 50.46

x = 2.523

Round to the nearest tenth:

x = 2.5

Question 3

The proportion is set up in the form 5/16 = 11/x. Multiply both sides by the second denominator, x, and then both sides by the first, 16. This will leave you with the work below:

5x/16 = 11

5x = 11(16)

Next, solve for x:

5x = 176

x = 35.2

Question 4

The proportion is set up in the form x/0.06 = 17/0.5. Multiply both sides by the second denominator, 0.5, and then both sides by the first, 0.06. This will leave you with the work below:

0.5x/0.06 = 17

0.5x = 17(0.06)

Next, solve for x:

0.5x = 1.02

x = 2.04

Round to the nearest tenth:

x = 2.0

Question 5

The proportion is set up in the form 29/x = 75/44. Multiply both sides by the second denominator, 44, and then both sides by the first, x. This will leave you with the work below:

29(44)/x = 75

29(44) = 75x

Next, solve for x:

1276 = 75x

x = 17.0133

Round to the nearest tenth:

x = 17.0

Answer:

1/ 112

Step-by-step explanation:

1-½ = ½ ( Mr. Daniel's leftover)

½×½= ¼ ( Mr. Richie)

½×¼= 1/8 ( Ms Laura)

½×1/8 = 1/16 ( Ms. Kimberly)

1/7 × 1/16 = 1/ 112 (the last turn)

so, Ms. Sarah eats 1/ 112 of a piece.

Answer:

50 percent

Step-by-step explanation:

Answer:

x= -1 y= -5

There for: (x, y). (-1,-5).

Step-by-step explanation:

Step one:

y=y

5x=9x+4

5x-9x=4

-4x=4

x= -1

Step two:

y=5x

y= 5(-1)

y= -5

Hope u find this helpful

Step-by-step explanation:

y=5x

y=9x+4

Substituting value of x in equation 2

y=9x+4

5x=9x+4

5x-9x=4

-4x=4

so x = -1

again

y=5x

y=5 * (-1)

so y = -5.

Answer:

61%

Step-by-step explanation:

1) We are changing the percent from 56 down to 22

2) This means that there will be a negative change in percent

3) This is because the new value (22) is smaller than the old value (56)

4) We must find the change from 56 to 22 in a percent

1) Find the difference between 56 and 22 as a number.

The difference between 56 and 22 is 34

2) Divide the result from Step 1 by the starting number 56.

34 ÷ 56 = 0.60714285714

3) Multiply the result from Step 2 by 100 to get it in terms of percent.

0.60714285714 x 100 = 60.71

4) Round the result from step 3 to the nearest percent.

60.71 ≈ 61%

Make sure you round to the nearest whole percent. In this case it would be 61%
