Answer:
C. P = 1.6w + 8.5
Step-by-step explanation:
In y= mx + b,
8.5 is (b) because it is the starting weight. The baby's weight gain would be represented by (m), because it changes every week.
Let the radius be: r and height be h
volume = πr²
if the radius is halved then radius = r/2
and height is doubled, so height= 2h
volume = πr*r/4*2h = π*r²*h/2
Thus the volume will be halved.
Answer:
a. about 15.51 miles, rounded to 15.5 miles
b. about 31.02 miles, rounded to 31 miles
Step-by-step explanation:
Sunday Monday Tuesday Wednesday Thursday Friday Saturday
10 20 40 80 160 320 640
1280 2560 5120 10240 20480 40960 81920
81920/5280 = 15.51515151, rounded to the nearest tenth of a mile, 15.5 miles
Question b asks for how many miles in total has he ran. That means we have to add each of the values shown above and that equals to 163830 feet.
Divide that by 5280 and that equals 31.02 miles, rounded to the nearest tenth, 31 miles.
