Let n be old painters time. Then the new painters are 2n. So:
1/n+1/2n=1/6
2+1=2n/6
2n=18
n=9
The old painters take 9 hours; the new ones take 18

Answer:
7. 20 + 5 + 3/10 + 6/100
8. 7 + 4/10 + 2/100 + 5/1000
Step-by-step explanation:
We are writing two numbers in expanded form, to help, we can use the guide above both numbers. Expanded form is all about breaking apart a number by place value and putting them in an additional sequence.
Let's look at 7, 25.36.
There are the tens, ones, tenths, and hundredths place being used, therefore :
20 + 5 + 3/10 + 6/100
We can do the same for 8, 7.425.
There are ones, tenths, hundredths, and thousandths being used, therefore :
7 + 4/10 + 2/100 + 5/1000

Answer:
The Value of Payments is P18,557.15
Step-by-step explanation:
The quarterly payment is an annuity payment.
Use the following formula to calculate the present value of the payments.
PV of Annuity = Annuity Payment x ( 1 - ( 1 + interest rate )^-Numbers of periods ) / Interest rates
Where
Annuity Payment = Quarterly payment = P1,300
Interest rate = 5.12% x 3/12 = 1.375%
Numbers of periods = 4 years x 12/3 = 16 quarters
PV of Annuity = Value of Payments = ?
Placing values in the formula
Value of Payments = P1,300 x ( 1 - ( 1 + 1.375% )^-16 ) / 1.375%
Value of Payments = P18,557.15
