The directions on a sewing pattern say to cut an extra 15% of fabric to account for error.
Chloe needs 0.75 yardof fabric to make a skirt, and she cuts 0.1125 yard.
Did Chloe cut the correct amount of fabric? Why or why not?

Answers

9514 1404 393

Answer:

no; the yardage should be more than 0.75 yards

Step-by-step explanation:

A value that is 15% more than 0.75 will be a number that is greater than 0.75. The number 0.1125 is much less than 0.75, so cannot be the correct amount of fabric.

Chloe did not cut the correct amount.

(the correct amount is 0.8625 yards)

_____

Additional comment

Often, all that is needed for answering a multiple choice question properly is ...

a) an understanding of what the question is asking

b) comprehension of what the answer must look like.

Here, the directions are saying to cut more than 0.75 yards. The result will be a value that is more than 0.75 (and less than 1).

The value 0.1125 yard is 15% of 0.75 yard. The cut amount should be that much in addition to 0.75 yard: 0.75 +0.1125 = 0.8625 yard.

There are only 6 blue pens, 5 green pens and 8 red pens in a box.
One pen is taken at random from the box.
Write down the probability that this pen is blue.

Answers

Answer:

0.316

Step-by-step explanation:

Probability = (number of outcomes)/(total number of outcomes)

In this case,

the total number of outcomes is 6+5+8 = 19, and

the number of outcomes for getting a blue pen = 6

Hence,

P(blue) = 6/19 = 0.31578947368 ≈ 0.316

How would Newton’s second law of motion impact the fitness routine of someone who is significantly overweight? Is there any type of fitness activity that a significantly overweight person could do where Newton’s second law of motion would not be a factor?

Answers

9514 1404 393

Explanation:

Newton's second law relates force, mass, and acceleration. For the same acceleration, more force is required to change the motion of more mass.

(a) Any fitness routine where velocity changes are involved will be impacted by Newton's second law. A significantly overweight person would have to expend significantly more energy to achieve the same changes of motion in the same period of time.

(b) Any fitness routine in which changes of speed or direction at a specific rate are not required will not be impacted by Newton's second law. These might be Tai Chi routines, weight lifting, or any other routines in which speed of completing a cycle of motion is not a factor.
