The perpendicular bisector of RT is B. SU.
Answer:
2.60 hours
Step-by-step explanation:
A hose fills a hot tub at a rate of ,
2.09 gallons ⇒ 1 minute
Now we have to find the time which takes to fill a 327 gallon hot tub.
For that, let the unknown time be x.
So,
2.09 gallons ⇒ 1 minute
327 gallon ⇒ x
Use cross multiplication to find the value of x.
2.09 x = 327 × 1
2.09x = 327
x = 327 ÷ 2.09
x = 156.45 min
Therefore, it takes 156.45 minutes.
But the question is asked for hours.
So,
Let us solve now.
156.45 ÷ 60 = 2.60 hours

1207 divided by 7 is equal to 172.4286
Answer:
24 hours
Step-by-step explanation:
If 12 workers take 10 hours to build a wall, assuming they build at the same rate, it would take one worker 120 hours to build a wall.
By this logic, it would take 120/5 or 24 hours for 5 workers to build a wall
Remember that the formula for simple interest is:
is the interest earned
is the principal amount invested
is the interest rate, represented as a decimal
is the amount of time in years
Using information the problem gave us, we can say that the amount of interest earned after one year is:
After 1 year, we will have earned $21. Remember though that we also need to find the amount we will earn after 4 months. Since there are 12 months in a full year, we can say that 4 mohts represents a third of a year. Thus, let's multiply our interest by one-third.
After 4 months, we will have generated $7 and after one year we will have generated $21.
