Part 1: The Easter Bunny wanted the children to have an Easter egg hunt on a soccer field,

which has dimensions of 75 yards by 120 yards. To honor the social distancing restrictions,

each egg must be placed 6 feet apart. What is the maximum number of eggs which can be

placed on the field? Hint: Did you notice the measurement units?

Answers

Answer:

13500

Step-by-step explanation:

to answer this question

convert the dimensions of the field to foot find the area of the fielddivide the area by the space of each egg

1 yard = 3 foot

75 yards = 75 x 3 = 225

120 yards = 120 x 3 = 360 ft

Area of a rectangle = length x width

225 x 360 = 81,000 ft^2

Maximum number of eggs = Area of the field / space the eggs must be apart

81,000 / 6 = 13,500

12. Find the height of the cone shown below if the volume is 3.6 cubic inches. Round your answer to the nearest tenth.

Answers

Answer:

h = 1.34 inches

Step-by-step explanation:

Given that,

The volume of cone, V = 3.6 cubic inches

Let the radius of cone is, r = 1.6 inches

We need to find the height of the cone. The formula for the volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h\\\\h=\dfrac{3V}{\pi r^2}\\\\h=\dfrac{3\times 3.6}{\pi \times 1.6^2}[/tex]

h = 1.34 inches

So, the height of the cone is equal to 1.34 inches.

The diameter of a circle is 14 ft. Find its area to the nearest tenth.

Answers

Answer:

The answer is 153.9

Step-by-step explanation:

To get the answer we will first divide 14 by 2 because we are trying to find the area.  14 ÷ 2 = 7.  Now multiply 7 x 7 x π, which equals 154.9 rounded to the nearest tenth.

Answer:

153.9 ft.²

Step-by-step explanation:

[tex]A=\pi r^2[/tex] where r is the radius of the circle

The radius is equal to half the diameter, so to find r, divide 14 ft. by 2:

14÷2=7

Plug 7 into the equation as r

[tex]A=\pi (7)^2\\A=\pi (49)\\A=153.9[/tex]

Therefore, the area of the circle is 153.9 ft.² when rounded to the nearest tenth.

Answers

Answer:

2x

Step-by-step explanation:

Given the expression  10x^3 + 16x^2 - 18x, we are to find the GCF

First find the factors

10x^3 = 2 * 5 * x * x^2

16x^2 = 2 * 8 * x * x

18x = 2 * 9 * x

From the factors shown, you will see that 2 and x are the common factors. Hence the GCF of the expression is 2x

A rectangle has perimeter 20 m . Express the area of the rectangle as a function of the length of ones its side.

Answers

Answer:

A = 10W - W²

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

Area of a rectangle =LW

L is the length

W is the width

Given

Perimeter = 20m

20 = 2 (L+W)

10 = L+W

L = 10 - W ....2

Substitute equation 2 into the formula for calculating the area

Recall that A = LW

A = (10-W)W

A = 10W - W²

Hence the area of the rectangle as a function of the length of ones its side is expressed as A = 10W - W²
