Answer:
Step-by-step explanation:
<em>Speed = distance/time</em>
- Distance = 20.4 miles
- Time = 17 minutes = 17*1/60 hours = 17/60 hours
<u>Speed is:</u>
- 20.4 : 17/60 =
- 20.4*60/17 =
- 72 mph
<u>Alyn exceeded the limit by:</u>
Answer:
6.3
Step-by-step explanation:
8.5 - (-4.8)
Let's focus on - (-4.8)
if a negative number is subtracted, it reverses itself
In other words, if a negative number is being subtracted, it is the same as being added as a positive number
So we change the equation to
8.5 + 4.8 = 13.3
Now we subtract 7 from 13.3
Since positive 7 is being subtracted, the rule for -4.8 does not apply to it
13.3 - 7 = 6.3
The volume of a sphere, V = (4/3)(PI)(R^3)
Let k = (4/3)(PI)
Therefore, V = k (R^3)
Let R’ = new radius = 2R
V’ =k (R’^3)
= k (2R)^3
= 8 k R^3
= 8 V
The volume would be eight time the original volume.
Answer:
Commutative property of multiplcation.
Step-by-step explanation:
An identifier for the property of multiplcation is by multiplying it by 1. Therefore the answer remains the same.
