Answer:

13.9%

Step-by-step explanation:

Given data

Expected weight = 230 pounds

Actual weight= 262 pounds

Required

The percent error

Error= Actaul- expected/ expected *100

Error= 262-230/230*100

Error=32/230*100

Error=0.139*100

Error=13.9%

Hence the error is 13.9%

rectangle A has a length of 24 meters and a width of 20 meters. rectangle B has the same area as rectangle A. the width of recta
blagie [28]
To solve this, first we'll find the area of the rectangle A,

Area=length × width
?=24m×20m
480m=24m×20m
480m squared=area of the rectangle A

now we'll find the width of rectangle B,
"the width of rectangle B is 12 meters less than the width of rectangle A",
20m-12m= 8m
8m=width of rectangle B

finally we'll find the length of rectangle B,
area of the rectangle B= 480msquared
width= 8m
length=? (to find this divide the area by the width)
480÷8=60m
length of the rectangle B=60m

A girls hair is 12 3/8 inches long if she had 2 1/2 inches cut off how long will her hair be ?
Darya [45]

Answer: 9 and 7eights

Step-by-step explanation: Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction. Which would equal, 9 and 7eights.
