Answer:
28.26m^2 (aka. 28.26 meters squared)
Step-by-step explanation:
The area of a circle is A=pi*r^2 where r is the radius of the circle.
Since r=3, then A=pi*3^2=9pi=28.26
Therefore, the area of the merry-go-round is 28.26 square meters
Answer: 10 meters
Explanation:
29 cm : blank meters
So how do we get from 348 cm to 29 cm?
To figure this out we divide.
348 divided by 28 = 12
we divided by 12 so we do the same with 120
120 divided by 12 = 10
So that’s the answer.
I hope this makes sense and helps you :)
If an number is an absolute value, it means that the number will be positive. You would plug and check the same way you would for any other equation and it a solution is considered extraneous if the equation is not equal
Answer:
Mean, μ = 200
Standard deviation, σ = 10
Step-by-step explanation:
Data provided:
a) true percentage of graduates who stay at their first job less than two years
p = 50% = 0.5
q = 1 - p = 1 - 0.5 = 0.5
Number of graduates selected in a group, n = 400
Now,
The mean is calculated as:
Mean, μ = p × n
or
μ = 0.5 × 400 = 200
and,
standard deviation, σ = 
or
σ = 
or
σ = √100
or
σ = 10
Answer:
<u>The rectangular parking lot has a width of 76 feet and a length of 40 feet</u>
Step-by-step explanation:
Let's find the length and the width of the rectangular parking lot, this way:
Perimeter = 232 feet
Perimeter = 2 Length + 2 Width
Length = Width - 36 feet
Now, substituting, we have:
2 (Width - 36) + 2 Width = 232
2 Width - 72 + 2 Width = 232
4 Width = 232 + 72
4 Width = 304
Width = 304/4 = 76 feet
Length = 76 - 36 = 40 feet
<u>The rectangular parking lot has a width of 76 feet and a length of 40 feet</u>
