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

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?
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 egg1 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.
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.
Find the volume of the cone in terms of pi.

Amount of gas used to cut one lawn (on an average) = 3/4 of a tak
Given ,
In a week , ten such lawns are cut
Hence, Total amount of gas used
= 3/4* 10
= 7.5 tank
APR of 0.995%. How much money would a $1000 investment be worth at the end of 5 years
Answer:
The amount in 5 years will be $1,050.75
Step-by-step explanation:
Here, we want to calculate the worth of the given amount of money in the next 5 years
We use the compound interest formula here;
A = P(1 + r/n)^nt
A is the amount after the given number of years
P is the amount invested which is $1,000
r is the rate which is 0.995% which is 0.995/100 = 0.00995
n is the number of times per year interest is compounded and that is 1
t is the number of years which is 5
substituting these values, we have
A = 1000( 1 + 0.00995/1)^5
A = 1000(1.00995)^5
A = $1,050.75

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