Answer:

82

Step-by-step explanation:

For this problem you would first round everything. 9.03 becomes 9, 19.87 becomes 20, 3.11 becomes 3 and 4.97 becomes 5. You then just do the problem. 9 + 20 = 29, multiplied by 3 makes 87, 87 - 5 = 82.

Maureen earned some money doing odd jobs last summer and put it in a savings account that earns 9% interest compounded quarterly
ivolga24 [154]

Answer:

Maureen earned $123.19 doing odd jobs

Step-by-step explanation:

The compound interest formula is given by:

A(t) = P(1 + \frac{r}{n})^{nt}

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.

In this question:

Compounded quarterly means that n = 4

10 years, so t = 10

9% interest, so r = 0.09

There is $300.00 in the account, which means that A = 300

How much did Maureen earn doing odd jobs?

This is P.

A(t) = P(1 + \frac{r}{n})^{nt}

300 = P(1 + \frac{0.09}{4})^{4*10}

(1.0225)^{40}P = 300

P = \frac{300}{(1.0225)^{40}}

P = 123.19

Lily drove 354 miles in 6 hours. On average, how fast did she drive in hours per mile?
vagabundo [1.1K]

Answer: \dfrac{1}{59}\ \text{hours per mile}

Step-by-step explanation:

Given : Distance traveled by Lily= 354 miles

Time= 6 hours

Then,

\text{LIly's rate in hours per mile}=\dfrac{6\text{ hours}}{354\text{ mile}}\\\\=\dfrac{1}{59}\ \text{hours per mile}

Hence, the required speed of Lily = \dfrac{1}{59}\ \text{hours per mile}
