<h3>
Answer: 50 mph</h3>
==============================================
Work Shown:
1/10 = 0.1
0.1 mile = 7.2 seconds
1 mile = 72 seconds (multiply both sides by 10)
1/72 mile = 1 second (divide both sides by 72)
3600/72 = 3600 seconds (multiply both sides by 3600)
50 miles = 3600 seconds
50 miles = 1 hour
The car's speed is 50 mph
Note: 1 hour = 60 min = 60*60 = 3600 seconds
ANSWER:
45, 912 = 4.5912 × 10^-4

Answer:
3 lb = $6.90
2 lb = $4.30
5 lb = $11.50
Step-by-step explanation:
To find that, we have to find the difference of 2130 and 2002, which is
2130-2002=128. We use subtraction due to that we start in 2002 but end in 2130, and therefore find the difference
Answer:
1 unit
Step-by-step explanation:
We have the following formula to find the length of an arc that subtends an angle of radians is:
S = rΘ where:
- r is the radius
- Θ is the subtended central angle given in radians
Given the information in this question, we have:
=> the length of an arc in this question is:
1*1 = 1 unit
Hope it will find you well
