Greetings! 

We can create an equation that can be used to solve problems of this kind:
90= (\frac{70}{100})x
Let x represent the number.

Solve for x.
90= \frac{70}{100}x

Divide both sides by \frac{70}{100}
\frac{90}{\frac{70}{100}}= \frac{\frac{70}{100}x}{\frac{70}{100}}

(\frac{90}{1})({\frac{100}{70}})=x

\frac{9000}{70}=x

Reduce the fraction to lowest terms or a decimal
\frac{900}{7}=x

The Answer Is:
\left[\begin{array}{ccc} x=\frac{900}{7}\end{array}\right]

70% of \frac{900}{7} is equal to 90.

Hope this helps!

A roller coaster can take 162 passengers around the track in nine minutes. The roller coaster operates at a constant rate.
aivan3 [116]

Answer:

<u>18</u> passengers the roller coaster can take around the track per minute.

Step-by-step explanation:

Given:

A roller coaster can take 162 passengers around the track in nine minutes. The roller coaster operates at a constant rate.

Now, to find the number of passengers roller coaster take around the track per minute.

As given in 9 minutes the roller coaster track 162 passengers.

So, we solve by using unitary method:

In 9 minutes the roller coaster take passengers = 162.

Thus, in 1 minute it can take =162\div 9 = 18.

Therefore, 18 passengers the roller coaster can take around the track per minute.

What is the area of the kite? (This was all that was given)
lesya [120]
The area of a kite is (1/2) * x * y, where x and y are the length of the two diagonals. In this case, the length of the two diagonals are 10 ft and 2 ft.
<span>Plug that in the equation, we get 1/2 * 2 * 10. We multiply the 2 and 10 first to get 20, that leaves us with 1/2 x 20, which is 10, so the area of this kite is 10 ft squared.</span>
