Mathematics

Alika [10]2 years ago
6 0

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.

Need help finding the missing angle
Nutka1998 [239]

Answer:

The missing dimension is

5

Step-by-step explanation:

The Pythagorean Theorem states that

{a}^{2}  +  {b}^{2}  =  {c}^{2}  \\

Note that c is the hypothenus <em>(</em><em>the</em><em> </em><em>hypothenus</em><em> </em><em>is</em><em> </em><em>always</em><em> </em><em>opposite</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>right</em><em> </em><em>angle</em><em> </em><em>of</em><em> </em><em>a</em><em> </em><em>triangle</em><em>)</em>

Therefore

{a}^{2}  +  {b}^{2}  =  {c}^{2} \\  {12}^{2}  +  {b}^{2}  =  {13}^{2} \\ 144 +  {b}^{2}   = 169 \\  {b}^{2}  = 169 - 144 \\  {b}^{2}  = 25

\sqrt{ {b}^{2} }  =  \sqrt{25}  \\ b = 5

Therefore the missing dimension is 5

If y varies directly as z and inversely as x and y = –18 and z = 3 when x = 6, find y when x = 5 and z = –5.
JulijaS [17]

Answer:

y = 36

Step-by-step explanation:

Given y varies directly as z and inversely as x then the equation relating them is

y = \frac{kz}{x} ← k is the constant of variation

To find k use the condition y = - 18, z = 3 when x = 6 , then

- 18 = \frac{3k}{6} ( multiply both sides by 6 )

- 108 = 3k ( divide both sides by 3 )

- 36 = k

y = \frac{-36z}{x} ← equation of variation

When x = 5 and z = - 5, then

y = \frac{-36(-5)}{5} = \frac{180}{5} = 36

1-1 Relations and Functions The following list details the numbers of tickets sold for a talent show: grade 9: 22; grade 10: 32;
zlopas [31]

Answer:

Domain = \{9, 10, 11, 12\}

Range = \{22, 32, 41, 30\}

Step-by-step explanation:

Given

Grade 9: 22

Grade 10: 32

Grade 11: 41

Grade 12: 30

Required

Determine the domain and the range

The domain and range of a function is represented as thus (x,y)

From the given parameters;

(x,y) = (Grade\ 9, 22), (Grade\ 10, 32) (Grade\ 11, 41), (Grade\ 12, 30)

Remove "Grade" to represent as only digits

(x,y) = (9, 22), (10, 32), (11, 41), (12, 30)

Split to x and y values:

<em>Where x = domain and y = range</em>

Domain = \{9, 10, 11, 12\}

Range = \{22, 32, 41, 30\}

<em>So, from the list of given options; option C answers the question.</em>
