Answer: 150 pounds
Step-by-step explanation:
Let the the astronaut weight on Earth be represented by x.
Based on the information given in the question, thus can be formed into an equation as:
16.5% of x = 24.75
16.5% × x = 24.75
16.5/100 × x = 24.75
0.165x = 24.75
x = 24.75/0.165
x = 150 pounds
The astronaut weigh 150 pounds on Earth.

Step-by-step explanation:
<span>The correct answers are A) 7.4 km/hr and B) 81.2 in/s.
Explanation:
A) The original ratio is 1 mi/13 min. We know that 1 mi = 5280 feet, so we have 5280 ft/13 min.
Each foot is 12 inches, so we have 5280*12 = 63360 in
63360 in/13 min
Each minute is 60 seconds; 13*60 = 780
63360 in/780 sec.
Dividing this, we get 81.2 in/sec.
B) 1 mi/13 min; 1 mile = 1609 m, so we have 1609 m/13 min.
1 m = 1000 km, so 1609 m = 1609/1000 = 1.609 km; this gives us 1.609 km/13 min.
An hour is 60 minutes, so we have 1.609 km/(13/60) hr; dividing this, we get 7.4 km/hr.</span>
Answer:

Step-by-step explanation:
The correct answer is (D). With a voluntary response sample, students with a stronger opinion on the food will be more likely to drop off a survey in the front office. Because the sample is not representative, no conclusions can be drawn about all students’ opinions of the food.
Answer:
-7y - 35
Step-by-step explanation:
-3 ( y) = -3y
-3 ( 5) = -15
-4 ( y) = -4y
-4 ( 5) = -20
-3y -4y = -7y
-15 -20 = -35
-7y -35
