Your first steps are correct.  Mult. the given fraction by (1+sqrt(5)) / (1+sqrt(5)).

Result:  8(1 + sqrt(5) )       8(1 + sqrt(5) )
             ------------------- = ----------------------
                 1 - 5                         -4

Must keep that denominator (-4).

Answer and Step-by-step explanation:

Answer and Step-by-step explanation:

Here is the equation for finding the sides (just to show):

68 = (2L + 2W)

We multiply L and W by 2 because there are two of the lengths and 2 of the widths.

Now, we add the scale factor to the outside, but on both sides of the equation.

68 × 1.5 = 1.5(2L + 2W)

Multiply 68 by 1.5.

102 = 1.5(2L + 2W)

The answer is 102.

The perimeter of the resulting rectangle is 102 ft.

amara earns $8 an hour at her job working 25 hours per week. If 22% of her paycheck goes to taxes, what is Tamara’s monthly cash
pantera1 [17]

Answer:

Answer is B. $624

Step-by-step explanation:

So first off, you multiply. Amara earns $8 every hour and she works 25 hours every week. There are 4 weeks in a month so we first multiply 25 × 4 and we get 100

Now we multiply 100 × $8 and you get $800

But then it says that 22% of her money goes to taxes. So what we have to do is reduce from that total gross pay ($800). So the first thing we do is change the 22% to a decimal by moving the invisible decimal point twice to the left and it leaves us with .22

Now, we multiply $800 × .22 and we get $176. Now, do not get confused! This $176 is not the final answer! That is just the amount of money we have to take away not the money it leaves us with.

So we take away now from our total: $800 - $176 = $624

And there's your answer! I hope this helps :)

andreyandreev [35.5K]

Answer: I am not sure exctly what the question is here but if you are wondering how many butterflies tatal for all species here it is:

North American Butterfrlies: 30

South American Butterflies: 18

Europe Butterflies: 12


Step-by-step explanation: To get the total number of butterflies per species you need to mulitply to find the correct ratio given the total number of North American Butterflies is 30

North American Butterflies to South American Butterflies is 5 to 3 so 30/5=6, you then multiply 3*6 to get 18 South American Butterflies.

Then since we now know there are 18 South American Butterflies and the ratio of those to Europe Butterflies are 3 to 2 we take 18/3=6, then multiply 2*6 to get 12 Europe Butterflies.
