Answer:
the original square area is 400 cm squared and the scaled square area is 25 so the difference between them is 375 cm squared.
Step-by-step explanation:
So first we need to find approximately the number of total students.
Rock I would say is about 200 people. Country, 100, Rap, 255, Classical, 64 as said before, and Blues, 80.
So if we add these all up we can find the total students.
200 + 100 + 255 + 64 + 80
699
Now the relative frequency is how many times something appears in a group.
Classical appears 64 times in about 700 people.
So, 64/700, is closest to the 0.9 selection.
There would be a 13 dollar tip if you round it. If you didn't it would be 13.05.
First you would turn the percent into a decimal. You would do this by moving the decimal place to the left 2 places. Then, multiply that by your amount.
ANSWER
EXPLANATION
We want to solve the trigonometric equation
We group like terms to obtain,
Divide both sides of the equation by 3 to get,
We can reciprocate both sides to get,
We simplify the right hand side to get,
Since the tangent ratio is negative, it implies that it is either in the second quadrant or fourth quadrant.
In the second quadrant,
In the fourth quadrant,
