Hi there
483.55$ in interest
Hope I helped <3
To find the percent of error divide how off the wrong answer was by the right number, then multiply by 100.
Bryan's guess of 730 was 120 less than the actual number so you would divide 120 by 850. 120/850 = 0.141
Then we would multiply that by 100. 0.141 * 100 = 14.1
His percent of error was 14.1%. The percent of error is negative since his guess was less than the right answer.
Answer:
115ft and 135 ft
Step-by-step explanation:
L - length
W - width
If width is x ft, then length is (x+20)
Put all in perimeter formula
500= 2 times ((x+20)+x)
500= 2 times (x+20)+x)
500=2 times (2x+20)
500=4x+40
4x=500-40
4x=460
x=460/4
So width is 115 ft, then length is 115+20=135 ft
There are two equations you will need in order to solve this question:
When you substitute 4y for x in the top equation, that should give you 20
