Answer:
79 minutes
Step-by-step explanation:
A plane is travelling at 180 meters per seconds
Convert to km/hr
180× 18/5
= 648 km/hr
Since 648 km equals 1 hour then the number of minutes required for the plane to travel 800 km is
= 1/648 × 800
= 1 hour 19 minutes
Conver the time to full minutes
60 minutes = 1 hour
= 60+19
= 79 minutes
Hence the minutes required for the plane to travel 800km is 79 minutes
The answer is 5 inches, you can find this by solving for r and plugging in the volume of the sphere for V and the pi would cancel out so it would be 500/3 * 3/4 and then you cube root it
Hi there!
Here, we're looking for the circumference. The formula for the circumference of a circle is pi x diameter. Using this formula, we can figure out the circumference.
WORK:
C = pi x 8
C = 8pi
or 25.13 in
Hope this helps!! :)
Answer: She paid the most for the gas in the first stop ($3.35 per gallon).
Step-by-step explanation:
1. At the first stop she put in 7.1 gallons of gas and paid $23.79, so she paid:
$23.79/7.1 gallons=$3.35 per gallon.
2. At her second stop she put in 5.8 gallons of gas and paid $19.08, then the price per gallon was:
$19.08/5.8 gallons= $3.28 per gallon.
3. At the third stop she put 6.6 gallons and paid $20.39, then:
$20.39/6.6 gallons=$3.08 per gallon.
4. Then, you can conclude she paid the most for the gas in the first stop ($3.35 per gallon).
