Answer:
0.8,√2,2π
Step-by-step explanation:
Sound travels 10200m farther through stone in 17 seconds than through aluminium
Speed of sound in aluminium = 3100 m/s
The speed of sound in stone = 3700 m/s
Time taken = 17 minutes
Distance traveled = Speed x Time
Distance traveled by sound in aluminium in 17 seconds = 3100 x 17
Distance traveled by sound in aluminium in 17 seconds = 52700 m
Distance traveled by sound in stone in 17 seconds = 3700 x 17
Distance traveled by sound in stone in 17 seconds = 62900 m
Difference in the distance traveled = 62900 - 52700
Difference in the distance traveled = 10200 m
Sound travels 10200m farther through stone in 17 seconds than through aluminium

Set up a pair of fractions:

500x = 828 (cross multiply)
x = 1.656 meters high should be the model (1.7 rounded)
Answer:
300 because 328 rounded to is 300 by 3<u>2</u>8 is rounded to 0 because its under 4 and the rest of the digits are 0 except the numbers before (if there are) the rounded number but the ones after the rounded number is 0
