Jessie estimates the weight of her cat to be 10 pounds. The actual weight of the cat is 1375 pounds. Find the percent of error.

Sloan [31]

Answer:

The percent error is 99%

Step-by-step explanation

Estimated weight of cat = 10 pounds

Actual weight of cat = 1375 pounds

We need to find the percent of error.

The formula used is: $Percent\:Error=\frac{|Estimated\:value-Actual\:Value|}{Actual\:Value}\times 100$

Putting values and finding percent of error.

$Percent\:Error=\frac{|Estimated\:value-Actual\:Value|}{Actual\:Value}\times 100\\Percent\:Error=\frac{|10-1375|}{1375}\times 100 \\Percent\:Error=\frac{|-1365|}{1375}\times 100 \\Percent\:Error=\frac{1365}{1375}\times 100\\Percent\:Error=0.99\times 100 \\Percet\:Error=99\%$

So, the percent error is 99%

Find the solution for a system of equations by elimination 3x – 6y = 12 5x - 2y = 10

sergiy2304 [10]

Answer:

y=2, x=1

Step-by-step explanation:

3x-6y=12(x2)

5x-2y=10(x6)

Eliminate y

6x-12y=12

30x-12y=60

-24x =-48

divide both sides by -24

-24x/-24=-48/-24

y=2

to get our x

3x-6(2)=12

3x-12=12

3x=12+12

3x=24(divide both sides by 3)

x=1
