A circle has circumference 200 pi feet.
What is the radius of the circle?
Answer: The diameter is two times the radius, so the equation for the circumference of a circle using the radius is two times pi times the radius. If you are given the circumference but not the radius or the diameter, you can still solve for one or the other using these formulas.
Step-by-step explanation:
The radius of the circle which has a circumference of the cirlce of 200π will be 100 feet.
What is the circumference of a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. The circumference of the circle will be
C = 2πr units
The circumference of the circle is given as 200π feet. Then the radius of the circle is given as,
200π = 2πr
Simplify the equation, then the value of the variable 'r' will be given as,
200π = 2πr
r = 100 feet
The radius of the circle which has a circumference of the cirlce of 200π will be 100 feet.

Devaughn is 10 years younger than Sydney. The sum of their ages is 74. What is Sydney's age? yearsold
Step-by-step explanation:
x = devaughn age
y = sydney age
x = y - 9
x + y = 61
y-9 + y = 61
2y= 61+9
2y = 70
y = 35
x = 35 - 9 = 26
check
35 + 26 = 61
35- 26 = 9

Three friends bought 4, 6, and 8 books.
This table shows the cost of the books.
Number of Books 4 6 8
Cost ($) 30 45 60
What is the constant of proportionality?
A. 2
B. 7.5
C. 15
D. 30
Answer:
B:7.5
Step-by-step explanation:
since 4 goes with 30, 6 goes with 45, and 8 goes with 60, you can see that 60-45 is 15 and 45-30 is 15 as well so the constant is 15, but the number of books is going up by two so the constant there is 2. So divide 15 by 2 and the answer would be C: 7.5.
Answer:
B. 7.5

A'Reana earns a weekly allowance for doing chores around the house and for keeping all of her grades above a C. During a particular week, she gave $10 to her friend Taylor, spent half of the remaining money on a new shirt, and then spent $7.50 on a pizza. At this point, she had $37.50. How much is A'Reana's weekly allowance?
Given :
During a particular week, she gave $10 to her friend Taylor, spent half of the remaining money on a new shirt, and then spent $7.50 on a pizza. At this point, she had $37.50.
To Find :
How much is Reana's weekly allowance.
Solution :
Let, allowance is x.
Then by given conditions :
37.50 = x - ( 10 + x/2 + 7.50 )
37.50 = x/2 - 17.50
x/2 = 55
x = $110
Therefore, Reana's weekly allowance is $110.
Hence, this is the required solution.

During a winter storm, a ski resort received 9 inches of snow in 12 hours. The snow fell at a steady rate. How many inches of snow fell at each hour.
Answer:
0.75 inches of snow
Step-by-step explanation:
During a winter storm, a ski resort received 9 inches of snow in 12 hours. The snow fell at a steady rate. How many inches of snow fell at each hour.
12 hours = 9 inches of snow
1 hour = x
Cross Multiply
12 hours × x = 1 hour × 9 inches
x = 9/12
x = 0.75 inches
Therefore, 0.75 inches of snow fell at each hour.

Different nerve signals travel at different speeds. Pressure and touch signals travel about 250 feet per second. Dull pain signals travel about 2 feet per second. How long does it take you to feel an ant crawling on your foot? Write your answer in a sentence using context. How much longer does it take to feel a dull ache in your foot? Write your answer in a sentence using context.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Pressure and touch signal speed = 250 feets per Second
Dull pain signal speed = 2 feets per second
Ant crawling on foot
A crawling ant on one's feet can be attributed to a touch signal, hence it will take ;
Time = Distance / speed
(Distance moved by crawling ant / 250)
(Dull ache in foot) = 250 / 2 = 125
It takes 125 times longer to feel a dull ache in foot.
If a line goes through points (-2, 9) and (0, 3), what is its slope?
3
-3
6
-1/3
Answer:
The slope of a line is:
[tex]m=-3[/tex]
Hence, option B is true.
Step-by-step explanation:
Given the points
(-2, 9) (0, 3)Finding the slope between (-2, 9) and (0, 3)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-2,\:9\right),\:\left(x_2,\:y_2\right)=\left(0,\:3\right)[/tex]
[tex]m=\frac{3-9}{0-\left(-2\right)}[/tex]
[tex]m=-3[/tex]
Therefore, the slope of a line is:
[tex]m=-3[/tex]
Hence, option B is true.
Parallelogram PQRS is shown.measure of angle s=(3x),measure of angle R=120, and measure of angle Q=(2y) find the value of X
Parallelograms have adjacent angles supplementary (sum to 180).
For pair r and s,
3x+120=180, => x=(180-120)/3=20 °
Similarly, for pair q and r,
2y+120=180 => y=(180-120)/2 = 30 °

When she checked the answer by estimating, it did not make sense. What error did Wen make?
Wen incorrectly converted a mixed number to an improper fraction.
Wen added the numerators and denominators instead of multiplying.
Wen did not take the reciprocal of the divisor.
Wen did not change the division problem to multiplication.

Answer It is composite number
Step-by-step explanation:
A composite number is a number that can be divided evenly by more numbers than 1 and itself. ... Since 85 cannot be divided by just 1 and 85, it is a composite number.
Hey there! :)
85 is composite.
All numbers that have more than 3 factors are composite numbers because they are 'composed' of some smaller numbers.

50% of the fruits collected were ripe. If 100 fruits were ripe, find the total number of fruits collected.
Answer:
200 fruits
Step-by-step explanation:
The questions states that 50% of the fruits were ripe, and that 100 fruits were ripe
Therefore: 100 = 50%
Which makes the total amount of fruits 200
Don't believe me? Reverse work:
200 / 2 = 100
200 = 100%, 100 = 50%
What is the equation of the line that is perpendicular to the line y = 6 and passes through the point (-4,-3)?
O x = -4
0 x = -3
Ox=-1/6

The equation of the line that is perpendicular to the line y = 6 and passes through the point (-4,-3)
Solution :
Let, equation of line perpendicular to given line is y = m ....1)
Here, m is a constant.
Putting y = -3 in above equation, we get :
-3 = m
Putting value of m in equation 1), we get :
y = -3
Therefore, correct option is b) x = -3.
Bobbie and Adam each own 35% of partnership BAB. On October 15, 2018, Bobbie sells her interest to Bob, who is a 30% partner. On October 16, 2019, Adam sells his interest to Bob. When does the partnership terminate?
Answer:
Step-by-step explanation:
Such partnerships only terminate when one of the partners sells his entire share which makes him no longer a partner in the company, but there may still be another partnership in the company. The other way all partnerships in the company terminate is when a single party/partner gains control of the entire companies' shares meaning they are 100% owner of the company and no other individual has any controlling interest in the company.
