Answer:

8=7t

Step-by-step explanation:

The table given shows that both variables are directly proportional to each other. That is, as s variable increases, y variable also increases.

Equation to represent this direct proportion would be:

8=kt,

where, k = constant of proportionality.

Let's find k from the table given.

Let's use any pair values of of s and t given in the table. Say, s = 21, t = 3

8=kt

21=k3

Divide both sides by 3

21/3= k3/3

7=k

k=7

Plug in k = 3 into :

8=7t

Hope this work!

Keelahs clothing store buys coats for $50 and then sells them for $80 what is the percent of mark up on the price of the coat sh
olchik [2.2K]
I don't know if you meant profit or markup but, 

take the difference of $80 & $50 = $30

What percent of 50 is 30? It's 3/5 or 60%. So there is a 60% markup on the original price of 50$.

Please someone help!! I tried my best to complete this problem but i'm stuck now (also am i even doing it right so far??!);(
Alik [6]

Answer and Step-by-step explanation:

You got everything correct so far except for #4.

4. Yes, it is 1. But it would be in months.

So you would put:

1 month = x

12 months = 1 year.

Since the population increases by 1.5 times a <em>month.</em>

For question number 3.

The equation should be:

f(x) = 100(1.5)^x <- Function

f(x) = 100(1.5)^{12} <- Function when x is 12 months (1 year)

(Put those both the same way I put it.)

It gives you the equation to work with, you just have to plug in the values.

1.5 is in the parenthesis because it needs to be the one that is raised by an exponent.

100 is the initial population, so it stays on the outside.

x is the exponent

Rewrite in radical form. If the number is rational, write it without using radical<br> (81)^(−1/4).
vesna_86 [32]

Answer:

1/3

Step-by-step explanation:

simplify

81^(-1/4)

= 1/81^(1/4)

= 1/[3×3×3×3]^(1/4). (factorize 81)

= 1/[3]^(4/4)

= 1/3
