Work and time are inversely proportional to each other. Then the time taken by Anita and Chao will be 3 hours and 26 minutes.
A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.
Anita can clean a typical pool in 8 hours.
Chao can clean a typical pool in 6 hours.
Work and time are inversely proportional to each other. Then we have
Let x be the time taken.
1/x = 1/6 + 1/8
1/x = 7 / 24
x = 24 / 7
x = 3 hours and 26 minutes

Step-by-step explanation:
if your here from the quiz that's the right answer
The interest rate should be ignored, because there’s nothing a consumer can do to change it.
b.
The interest rate is essentially how long you have to pay off your loan, and the shorter the better.
c.
The interest rate can drastically change the total amount paid to the lender, in the case of mortgages, up to thousands of dollars.
d.
The interest rate does not change, even between banks, so choosing the right time to borrow is essential.
Answer:
The correct answer is c. The interest rate can drastically change the total amount paid to the lender, in the case of mortgages, up to thousands of dollars.
Step-by-step explanation:
The formula of interest is A=P (1+r)ⁿ
A=Final amount
P= Principal ( deposit)
r= interest rate
n= time
As we can see, interest rate will be added to the final amount. If the interest rate is higher , higher will be the amount. So, it is an important issue when you are evaluating a loan.
They now had the same amount in their accounts.
How much did they initially have altogether?
Answer:
£780 and £1300
Step-by-step explanation:
The ratio in their accounts is 3 : 5 = 3x : 5x ( x is a multiplier )
Terry put £220 into his account, then 3x + 220
Faye withdrew £300 from her account then 5x - 300
They now have the same amounts in their accounts, thus
5x - 300 = 3x + 220 ( subtract 3x from both sides )
2x - 300 = 220 ( add 300 to both sides )
2x = 520 ( divide both sides by 2 )
x = 260
Thus initial amount in their accounts
3 × £260 = £780 ← Terry's account
5 × £260 = £1300 ← Faye's account
