Answer:
the answer is 180 students.
Step-by-step explanation:
I got this by subtracting 15 by 100 and got 75. This means 75% chose purple. Then you take 75% of 240 and that's your answer
Answer:
$4
Step-by-step explanation:
Quick tip about 20% tips.
Move the decimal over 1 place to the left and multiply by 2.
For this equation it would look like this:
18.37 ---> 1.837
(1.837)(2) = 3.674
So, if we rounded to the nearest dollar like the question is asking then we round to $4.
Another way to do this is to multiply 18.37 by .20:
(18.37)(.20) = 3.674
Either way it is $4.

Two planes may intersect, be parallel, or coincide .
If two planes intersect, then the set of common points is a line that lies in both planes. Two parallel planes can not intersect.
The intersection of two planes that do not coincide (if it exists) is always a line.
If an intersection of the planes does not exist, the planes are said to be parallel.
The measure of an obtuse angle is greater than 90 degrees and less than 180 degrees.
If by description you mean simplification then: 84x/28
