15. Viruses are much smaller than bacteria, Some viruses measure 0,0001 mm in
diameter. An artist's diaggam of a virus
shows the diameter as 5 mm. Determine
the scale factor used,

answer: b.36 feet

step-by-step explanation:

the best estimate is 3 because   8 can only go into 24 3 times

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
