Answer:

3.26

Step-by-step explanation:

You round the second place after the decimal (6) by the place after it (4).

If the place after the number you need to round is a 5 or up, the decimal you round goes up one, if it is a 4 or lower it stays the same.

E.G. if 3.2649 was 3.2659 the hundreds would be rounded to 3.27. Since it's a 4, the six stays the same at 3.26.]

hope this helps (/o.o)/<3

Answer:

3.26

Step-by-step explanation:

Rounding to the nearest hundredth means round to the nearest two decimal places.

To do this, all we need to look at is the 3rd decimal place.

Since 4 is not 5 or greater, that means we must round down, no matter how close it is to 5.

Therefore, the answer should just be 3.26

Answer:

$1,094,748.09
$8600.28
11 years, 10 months

Step-by-step explanation:

a) The compound interest formula can be used:

A = P(1 +r/n)^(nt)

where P is the principal invested at annual rate r compounded n times per year for t years.

A = $750,000(1 +.038/4)^(4·10) ≈ $1,094,748.09

Tamsyn's account will have a balance of $1,094,748.09 when she retires.

b1) The amortization formula is good for this.

A = P(r/n)/(1 -(1 +r/n)^(-nt))

where P is the amount earning interest at annual rate r compounded n times per year for t years.

A = $1,094,748.09(0.049/12)/(1 - (1 +0.049/12)^(-12·15)) ≈ $8600.28

Tamsyn can withdraw $8600.28 per month for 15 years.

b2) The account balance after n months will be ...

B = P(1 +r/12)^n -A((1+r/12)^n -1)/(r/12)

Filling in the known values and solving for n, we have ...

300,000 = 1,094,748.09(1.1.00408333^n) -8600.28(1.00408333^n -1)/.000408333

300,000 = 1,094,748.09(1.1.00408333^n) -2,106,191.02(1.00408333^n -1)

-1,806,191.02 = -1,011,442.93(1.00408333^n)

1.785757 = 1.00408333^n

n = log(1.785757)/log(1.00408333) = 142.3

After about 11 years 10 months, the account balance will be $300,000.

Which equation can be used to solve for the rate, r, for Sam to change all the light bulbs in the office building by himself?

Bad White [126]

Answer:

$\frac{3}{r}+\frac{3}{8}=1$

Step-by-step explanation:

Given question is incomplete; here is the complete question.

Working together, Sam and Charlie can change all light bulbs in the office building in 3 hours. It would have taken Charlie 8 hours to do the job alone. Which equation can be be used to solve for the rate 'r', for Sam to change all the light bulbs in the office building by himself.

Let Sam can change the bulbs in the office alone in 'r' hours

Per hour work done by Sam alone = $\frac{1}{r}$
