Answer:
3620.57
Step-by-step explanation:
Given: Stacy hits the jackpot one day at the gumball machine and won 4 gumballs, radius of each gumball is 6 mm
To find: Total volume of all 4 gumballs
Solution:
Gumball is Spherical
Volume of Sphere = (4/3)πr³
r = Radius of Sphere
r = 6mm
Volume of 1 gumball = (4/3)π * 6³
= 288π mm³
Volume of 4 gumballs = 4 * 288π
= 1152π mm³
using π = 22/7
= 3,620.57 mm³
or using π = 3.14
= 3,617.28 mm³
Volume of 4 gumballs = 288π mm³ ≈ 3,620 mm³
Martha is indeed right when she states that -6 is a rational number. Just like the name implies, a rational number is a number that can be written as a/b with b not equal to 0. Since -6 can be written as -6/1, and since that is a ratio, that is why -6 is a rational number.
For this case, the first thing we must do is define variables.
We have then:
x: time in minutes
y: distance traveled.
We then have the following equations:
For Kathleen:
For Arnob:
By the time Arnob reaches Kathleen we have:
From here, we clear the value of x.
We have then:
Answer:
it takes Arnob to catch up to Kathleen 75 minutes:
d. 75
