Sam measured the height of a window frame as 5.23 feet, but the actual height was 6 feet. What is the percentage of error in Sam's measurement?

Answers

Answer 1
Answer:

Answer: 12.83%

Step-by-step explanation:

Given : Sam measured the height of a window frame as 5.23 feet, but the actual height was 6 feet.

i.e. Estimated height = 5.23 feet

Actual height = 6 feet

Then, the percentage of error in Sam's measurement will be :-

\%\text{Error}=\frac{|\text{Estimated height-Actual height}|}{\text{Actual height}}*100\n\n=(|5.23-6|)/(6)*100\n\n =(0.77)/(6)*100\n\n=12.8333333333\approx12.83\%

Hence, the percentage of error in Sam's measurement= 12.83%

Write an expression that can be used to multiply 6 times 198 mentally

Answers

I would half 198, get
99 and add a 0, this is how you multiply by 5 in your head

198*5 = 990
990 + 200 = 1190 - 2
= 1188

Alternatively we can round 198 to 200: then multiply by 6

200*6 = 1200

Then We subtract the 6 "2's" that we added

1200 - 12 = 1188


The expression for this is:
(6*200) - (6 * 2)
