I don’t know the answer to that one can you help me please
dybincka [34]

Answer:

16/45

Step-by-step explanation:

Step 1:  When dividing fractions, use “KFC”.  It means Keep the first fraction, Flip the second one, and  

              Change it to multiplication

-4/20 ÷ -9/16    →    -4/20 ∙ 16/-9

Step 2:  Reduce any fractions if necessary, it makes multiplying them easier and you will have to reduce anyway at the end.  It’s easier arithmetic to reduce at this step.  The first fraction reduces because both the numerator and denominator are divisible by 4.  

-1/5  ∙   16/-9    

Step 3:  Multiply numerators and denominators together to get one fraction

(-16)/(-45)  

Step 4:  Cancel out the negatives, a negative divided by a negative is a positive.  Our final answer is

 

16/45

A wire is to be attached to support a telephone pole. Because of surrounding buildings, sidewalks, and​ roadways, the wire must
ad-work [718]
This situation is a right triangle with the base measuring 18 and the hypotenuse 22.  We are looking for x, the height up the pole that the wire is going to be attached to.  We will use Pythagorean's Theorem to find the missing length.  22^2-18^2=x^2  and  484-324=x^2.  x^2 = 160 so x = 4 \sqrt{10} or 12.65 feet

Solve the proportions 28/35=8/r
mash [69]

ANSWER

r = 10

EXPLANATION

To solve for r first we have to put r in the numerator. To do that, we have to multiply both sides of the proportion by r:

\begin{gathered} \frac{28}{35}\cdot r=\frac{8}{r}\cdot r \\ \frac{28}{35}r=8 \end{gathered}

Now, we have to multiply both sides by 35:

\begin{gathered} \frac{28}{35}r\cdot35=8\cdot35 \\ 28r=280 \end{gathered}

And finally divide both sides by 28:

\begin{gathered} \frac{28r}{28}=\frac{280}{28} \\ r=10 \end{gathered}

You are choosing between two health clubs. Club A offers membership for a fee of plus $18 a monthly fee of $20 Club B offers mem
AlexFokin [52]

Answer:

x=5

Step-by-step explanation:

so after five months, the costs would equal each other.

Explanation:

You'd have to write equations for the price per month for each club.

Let x equal the number of months of membership, and y equal the total cost. Club A's is y=25x+40 and Club B's is y=30x+15.

Because we know that the prices, y, would be equal, we can set the two equations equal to each other.

25x+40=30x+15.

We can now solve for x by isolating the variable.

25x+25=30x.

25=5x.

5=x

After five months, the total cost would be the same.
