Answer:
The answer is 96%
Step-by-step solution:
I just took the test and the way my test is set up, it doesn't show you the answer, you just have the ability to do it again and again with no limit. I saw that most people got all the other questions right but the salon one. And I did too before but after doing it over and over again I finally understood. So the question is Customer Retention = (# Customers at End of time Period less New Customers)/Customers at beginning of time Period
Multiply the result by 100 to convert to percentage
So pretty much what the question is saying is to subtract the numbers at End of time Period by the new costumers then divide that by the costumers at beginning of time Period then multiply the solution by 100 for the percentage. Most people probably dismissed the word less but it's indeed important and it would've been simpler if they just put a subtract sign but hey we got the answer anyway.
Answer: See below
Step-by-step explanation:
The Pythagorean Theorem is a²+b²=c². Since each problem gives us the length of a, b, or c, we can directly plug them into this equation and solve.
Triangle EFG
9²+b²=41²
81+b²=1681
b²=1600
b=√1600
b=40
----------------------------------------------------------------------
Triangle PQR
20²+21²=c²
400+441=c²
c²=841
c=√841
c=29
----------------------------------------------------------------------
Triangle XYZ
a²+24²=25²
a²+576=625
a²=49
a=√49
a=7
Answer:
x = 3 , y = 1
Step-by-step explanation:
2x + y = 7
3x + y = 8
solution
2x + y = 7-----------(1)
3x - y = 8------------(2)
from equation 1
2x + y = 7
y = 7 - 2x-------------(3)
substitute equation 3 into equation 2
3x - y = 8
3x - (7 - 2x) = 8
3x - 7 + 2x = 8
3x + 2x = 8 + 7
5x = 15
divide through by the coefficient of x
5x/5 = 15/5
x = 3
to find y
substitute x into equation 1
2x + y = 7
2(3) + y = 7
6 + y = 7
y = 7 - 6
y = 1
Answer: The answer is (B)
