D (38.63) because it wouldn’t make sense if the number was less than 10 when the line is clearly longer
Answer:
152.4
Step-by-step explanation:
30%+10%=40%
100%-40%=60%
254*0.60=152.4
Answer:
2.5 (2 1/2)
-1.25 (- 1 1/4)
5.33333…. (5 1/3)
(4)
0.6 (3/5)
If you check, each of these can be written as a fraction.

Answer:
Exponential growth; 40%
Step-by-step explanation:
Just to explain,
the equation A(t)=P(1+r)^t is the standard equation for exponential growth
what youre looking at is the 'r' portion which is the .4 in that equation
to get your percent from the decimal, move the decimal to the right 2 places to go from .40 to 40%
Answer:
Ratio = 
Step-by-step explanation:
Volume of Sphere is given by the formula:

Where
V is the volume
and
r is the radius
Original Volume, given r = 3, would be:

Increased snowball volume:
Radius increased 0.25 per second, he spent 4 seconds, so radius increase:
0.25 * 4 = 1 cm
New radius = 3 + 1 = 4 cm
New Volume would be:

Ratio of New Volume to Original would be:

This is the ratio for current volume to original volume.
