To solve this problem you must apply the proccedure shown below:
1. You have that the formula for calculate the area of a triangle is:
A=bh/2
Where A is the area of the triangle, b is the base of the triangle and h is the height of the triangle.
bh/2=124
bh=124x2
bh=248
2. The problem asks for the new area of the triangle <span>if its base was half as long and its height was three times as long. Then, you have:
Base=b/2
Height=3h
3. Therefore, when you substitute this into the formula for calculate the area of a triangle, you obtain:
A'=bh/2
(A' is the new area)
A'=(b/2)(3)/2
A'=3bh/4
4. When you substitute bh=248 into </span>A'=3bh/4, you obtain:
<span>
A'=186 units</span>²
<span>
The answer is: </span>186 units²
They're all equal. They would all be $87.
To find, divide each price by the number of tires.
The compound interest is obtained as $91.81, rounded off to the nearest hundredth.
<h3>How is compound interest estimated annually?</h3>
In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest. The entire compound interest is then obtained by deducting the initial principal.
The equation that results will look like this:
Compound Interest =
Amount, rate of interest and time is given as $1500, 2% and 3 years respectively.
First, change r as a percent to r as a decimal.
r = R/100
r = 2/100
r = 0.02 rate per year,
Then solve the equation for compound interest.
So, the compound interest is obtained as $91.81, rounded off to the nearest hundredth.

Answer:
62.67%
Step-by-step explanation:
Total revenue of a company from music sales is 14.2 billion dollars in 1999.
It reaches 5.3 million in 2014.
We need to find the percent decrease in music revenue. It can be given by :
![\%=\dfrac{|\text{original value-decrement value}|}{\text{original value}}\times 100\\\\\%=\dfrac{|14.2-5.3|}{14.2}\times 100\\\\\%=62.67](https://tex.z-dn.net/?f=%5C%25%3D%5Cdfrac%7B%7C%5Ctext%7Boriginal%20value-decrement%20value%7D%7C%7D%7B%5Ctext%7Boriginal%20value%7D%7D%5Ctimes%20100%5C%5C%5C%5C%5C%25%3D%5Cdfrac%7B%7C14.2-5.3%7C%7D%7B14.2%7D%5Ctimes%20100%5C%5C%5C%5C%5C%25%3D62.67)
So, the percent decrease in music revenue is 62.67%.
