Answer:
10π or 31.4 inches
Step-by-step explanation:
Well circumference is perimeter on a circle
The radius is given
To find Circumfrence you can either,
c=2rπ
Or
c=dπ
We have the radius in this scenario so
c=2*5*π
Answer:
Circumference= 2pie(r)
=2(3.14)(5)
=31.4 in
Circumference= 31.4 in

The average age of the ten people on my basketball team was 13.5, but then a fifteen year old joined our team and an 11 year old quit the team. What is the average age of my team now?
Answer:
The new average is 134/10, or 13.4 years.
Step-by-step explanation:
a + b + c + d + e + f + g + h + i + j
------------------------------------------------ = 13.5 (the original average)
10
15 years is 1.5 year older than the 13.5 average and 11 years is 2.5 younger than that. The net change is 1.5 - 2.5, or -1. The number of players remains the same: 10. We subtract 1 from the sum of the player ages and divide the result by 10:
a + b + c + d + e + f + g + h + i + j - 1
--------------------------------------------------- = 13.4 (the new average)
10
Note that the sum of the original 10 ages is (10)(13.5), or 135, which becomes 134 after the 15-year-old joined the team and the 11 year old quit. The new
average is 134/10, or 13.4 years.

A scuba diver was rising back to the surface after taking photos under water. At 2:50 P.M.,
he was at an elevation of 15.3 feet. At 2:55 P.M., the diver’s depth was 3.7 feet. By how
many feet did the diver’s position change from 2:50 P.M. to 2:55 P.M.
Answer:
the answer is 11.6 feet
Step-by-step explanation:
you simply subtract the feet of the depth he was at at 2:55pm from his depth at 2:50pm

Step-by-step explanation:
A trader bought 40 shirts for Birr 220 and sold them at Birr 72 each
Find the profit percentage.
Given:
Cost price of 40 shirts = Birr 220
Selling price of each shirt = Birr 72
To find:
The profit percentage.
Solution:
We have,
Cost price (CP) of 40 shirts = Birr 220
Selling price (SP) of each shirt = Birr 72
So, the selling price (SP) of 40 shirts is:
[tex]72\times 40=2880[/tex]
We need to find the profit percentage.
[tex]\text{Profit percentage}=\dfrac{SP-CP}{CP}\times 100[/tex]
[tex]\text{Profit percentage}=\dfrac{2880-220}{220}\times 100[/tex]
[tex]\text{Profit percentage}=\dfrac{2660}{220}\times 100[/tex]
[tex]\text{Profit percentage}=1209.09\%[/tex]
Therefore, the profit percentage is 1209.09%.

Step-by-step explanation:
y = x/7 -18 What is the value of y when x = 133?
*Please show work. (Is not mandatory but try to*
Answer:
1
Step-by-step explanation:
(133)/7 - 18
133 ÷ 7 = 19
19 - 18 = 1
Answer: y = 1
Step-by-step explanation:
Well if x is 133 then the problem is y = (133/7) -18
and 133/7 is 19
so the problem is y = 19 - 18
and 19 - 18 is 1, so
y = 1

Answer:
1). The correct answer is letter A)
6). The correct answer is letetr D)
Step-by-step explanation:
Let be the equation of a sin function:
[tex]sin(x)=Asin(B(x+C))+D[/tex]
Where:
A is the amplitudeThe period is 2π/BC is the phase shift leftD is the vertical shiftWe can see from the image of the problem (6):
The amplitude is: A = 3 units
The vertical shift is: D = 6 units
The phase shift is: C = π
The period is : P = 4π = 2π/B then B = 1/2
Therefore the correct answer is letetr D)
[tex]sin(x)=3sin(0.5(x+\pi))+6[/tex]
In the problem (1) we have:
The amplitude is: A = -2 units
The vertical shift is: D = 6 units
The phase shift is: C = π/4
The value of B = 1
Then the correct answer is letter A)

If the length of the 45° region of this circle is 10 inches, what is the radius of the circle? Use and round to the nearest tenth.
Answer:
12.71in
step explanation:
The Length of an arc given is expressed as;
A = theta/360 * 2πr
10 = 45/360 * 2 * 3.14r
10 = 1/8 * 6.28r
Cross multiply
10 * 8 = 6.28r
80 = 6.28r
r = 80/6.28
r = 12.74in
Hence the radius is 12.71in
It took a train 2 3/5 hours to travel 87 1/10 miles. What was the train's

Madeline invests $25,000 in an account that offers a compound interest rate
of 9.5% per year. Which of the following is the correct equation for how much
Madeline will have after 8 years?
The correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex] which is in option [tex](b)[/tex].
What is compound interest ?Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest
Amount [tex]=P(1+\frac{R}{100})^t[/tex]
We have,
Principal [tex]=\$25,000[/tex]
Rate[tex]=9.5\%[/tex]
Time [tex]=8[/tex] years
Now,
Using the above mentioned formula,
Amount [tex]=P(1+\frac{R}{100})^t[/tex]
[tex]=25000(1+\frac{9.5}{100})^8[/tex]
Amount [tex]=25000(1+0.095)^8[/tex]
So, the equation for final amount is [tex]25000(1+0.095)^8[/tex].
Hence, we can say that the correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex] which is in option [tex](b)[/tex] .
