Answer:
10 hours to drive 500 miles
6 hours to drive 300 miles
Step-by-step explanation:
Hi, to answer this we have to calculate the speed rate first:
Speed = distance /time
Speed = 200 miles / 4 hours = 50 miles per hour
So, to find the time for each number of miles:
Time = distance /speed
For 500 miles:
t = 500/50 = 10 hours
For 300 miles
t = 300/50 =6 hours
So, in conclusion:
It will take 10 hours to him drive 500 miles
It will take 6 hours to him drive 300 miles
7+d=19 is the answer
subtract 7 from each side d=19-7
d=12
Answer:
Step-by-step explanation:
Statistically this is valid
But, in Alaska average daytime summer temperatures range from approximately 55 to 78 °F (12.8 to 25.6 °C); average daytime winter temperatures are about 5 to 30 °F (−15.0 to −1.1 °C). SO, they don't need cooling when compared to rest of the USA. Therefore this will not be valid.
Answer:
Zamir 75%
Caleb 72%
Rosa 76%
Work
<u>Zamir</u>
.75=75%
75*40=3000
3000/ 100= 30
<u>Zamir got 30 out of 40</u> questions right
<u>Caleb</u>
30-12=18
<u>Caleb got 18 out of 25</u> questions right now find percent
18*100=1800
1800/ 25= 72
Caleb got 72%
<u>Rosa</u>
18+1=19
<u>Rosa got 19 out of 25 </u>questions correct now find percent
19*100=1900
1900/ 25=76
Rosa got 76%
Looks like an angle bisector to me
