7. The ratio of an object's weight on Earth to its weight on Neptune is 5 : 7. How much would a person who weighs 150 pounds on Earth weigh on Neptune?

A. 170 pounds
B. 107 1/7 pounds
C. 750 pounds
D. 210 pounds

I answered D, because I took 150 pounds and divided that by 5 then I multiplied that by 7, which equals 210 pounds. Is that right?

17. Of the employees who work at Stalling Printing, 90% attended the safety procedures meeting. If 63 employees attended the meeting, how many employees work at Stalling Printing?

A. 70
B. 57
C. 143
D. 128

I picked A, because I took 63 employees and divided that by 90 %, which gave me 0.7, which I multiplied by 100 which equals 70. So 70 people work at stalling printing. Is that correct?

Both are right. :-)

Thanks!

You're welcome.

ITS D 210

For the first question, you made a mistake in your calculation. To find the weight of a person on Neptune, you need to multiply their weight on Earth by the ratio of weight on Earth to weight on Neptune, which is 5/7. Let's calculate it correctly:

Weight on Neptune = (Weight on Earth) * (Weight on Neptune / Weight on Earth)
Weight on Neptune = (150 pounds) * (7/5) = 210 pounds

So the correct answer is D. The person would weigh 210 pounds on Neptune.

Now, let's move on to the second question. Your calculation method is correct, but you made a small error in your calculation.

To find the total number of employees at Stalling Printing, you need to divide the number of employees who attended the meeting (63) by the attendance percentage (90%). So let's calculate it correctly:

Total number of employees = (Number of employees who attended the meeting) / (Attendance percentage)
Total number of employees = 63 / (90/100) = 63 / 0.9 = 70

So the correct answer is A. The total number of employees at Stalling Printing is 70.

Great job, you were close in both answers!
