Answer:
11 hours 15 mins
Step-by-step explanation:
Wilma & Betty both have a pool that holds 10500 gallons of water each.
Wilma's garden hose fills at the rate of 700 gallons per hour.
Betty's garden hose fills at a rate of 400 gallons per hour.
Volume = Rate * time
Time = Volume /rate
The time it will take for Wilma's pool to be filled = 10500/700
= 15 hours
The time it will take for Betty's pool to be filled = 10500/400
= 26.25hours
= 26 hours 15 minutes
it will take Betty (26.25 - 15) to fill her pool than Wilma.
= 11.25hours
= 11 hours 15 mins
Answer:
1436.03 units³
Step-by-step explanation:
The formula for the volume of a sphere of radius r is
V = (4/3)πr³. We'll use 3.14 for π.
Then:
V = (4/3)(3.14)(7 units)³. To the nearest hundredth: 1436.03 units³
Answer:
Morgan divided 2 throughout the original equation, giving her |x-3.5|=2.5.
x = 6 and x = 1
Step-by-step explanation:
|2x-7|=5 -- divide by 2
|x-3.5|=2.5 and |x-3.5|=-2.5 -- since this is an absolute value equation, we have to consider both positive and negative
x-3.5 = 2.5
x = 6
x-3.5 = -2.5
x = 1
Answer:
10
Step-by-step explanation:
If she multiplied by 10 imagine it as the decimal moving once to the right per every 0. So 2.7 x 10 = 27
