The stadium has 9400 seats. 7990 of these seats are in the sun today. What percent of seats are NOT In the sun?

15%

Step-by-step explanation:

We assume, that the number 9400 is 100% - because it's the output value of the task.

x is the value we are looking for.

If 100% equals 9400, so we can write it down as 100%=9400.

We know, that x% equals 7990 of the output value, so we can write it down as x%=7990.

Now we have two simple equations:

100%=9400

x%=7990

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=9400/7990

Now we just have to solve the simple equation, and we will get the solution we are looking for.

Solution for 7990 is what percent of 9400.

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
