What process do you use to find the percent change of a quantity?

Answers

Answer 1

Answer: First, we need to get the amount of change:
The amount of change can either be an increase or a decrease.
It can be calculated as follows:
amount of change = $($

If the amount of change is positive, then it is an increase
If the amount of change is negative, then it is a decrease

Then, we need to convert this amount into a percentage:
Changing the amount into a percentage can simply be done by multiplying this amount by 100
This means that:
% of change = amount of change * 100

Combining the two steps:
% of change = $($ * 100

Examples:
The original price of a certain product was $10. It then became $12. Find the % of increase.
% of change = $(12-10)/(10) * 100$ = 20%
This means that the price increased by 20%

The temperature decreased from 25 degrees to 20 degrees. Find the percentage of decrease.
% of decrease = $(20-25)/(25) * 100$ = -20%
This means that the temperature decreased by 20%

Hope this helps :)

Answers

Total inches: 24 x 2 + 16 x 2

= 48 + 32 = 80 inches

80 in x 0.5 = 40m

The mean sustained wind velocity, v, can be determined by the equation v = 6.3 StartRoot 1013 minus p EndRoot, where p is the air pressure, in millibars, at the center of the hurricane. What is the approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second?

Answers

Answer:

909.8 millibars.

Step-by-step explanation:

The mean sustained velocity, v be determined by the equation:

$v=6.3√(1013-p)$ , where p is the air pressure, in millibars, at the center of the hurricane.

Given that: v=64 meters per second, we are to find the value of p.

$64=6.3√(1013-p)\n$Square both sides to eliminate the square root sign\n(64)^2=(6.3√(1013-p))^2\n4096=39.69(1013-p)\n$Divide both sides by 39.69$\n(4096)/(39.69)=1013-p\n $Therefore:$\np=1013-(4096)/(39.69)\n\np=909.8$ millibars$

The approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second is 909.8 millibars.
