ZanzabumX [31]

Time taken to fill the bathtub is 8 min
time taken to drain the bathtub is 12 min
fraction of bathtub filled in 1 hour=1/8
fraction of bathtub drained in 1 hour=1/12
fraction that will be filled in a minute given that both taps are opened at he same time:
1/8-1/12
=1/24
thus time taken for the bathtub to be filled is 24 min

A new bank customer with $4 comma 500 wants to open a money market account. The bank is offering a simple interest rate of 1.5

Jet001 [13]

a) Simple interest earned by customer in 10 years is $ 675

b) Account balance after 10 years is $ 5175

<em><u>Solution:</u></em>

<em><u>The simple interest is given by formula:</u></em>

$Simple\ Interest = \frac{p \times n \times r}{100}$

Where,

"p" is the principal

"r" is the rate of interest

"n" is the number of years

<em><u>a. How much interest will the customer earn in 10 years?</u></em>

From given,

Principal = p = $ 4500

Simple interest rate = r =1.5 %

n = 10

Substituting the values in formula,

$Simple\ Interest = \frac{4500 \times 10 \times 1.5}{100}\\\\Simple\ Interest = 450 \times 1.5\\\\Simple\ Interest = 675$

Thus simple interest earned by customer in 10 years is $ 675

<em><u>b. What will the account balance be after 10 years ?</u></em>

Account balance = principal + simple interest

Account balance = 4500 + 675 = 5175

Thus account balance after 10 years is $ 5175

If you copy a page on a machine at 72%, you should get a similar copy of the page. What is the corresponding setting to obtain t

allsm [11]

Answer:

$138\frac{8}{9}\%$

Step-by-step explanation:

we know that

To find out the corresponding setting to obtain the original from the copy, divide 100% by 72%

so

$\frac{100}{72}$

Simplify

$\frac{100}{72}=\frac{25}{18}$

Convert to percentage

$\frac{25}{18}(100)=\frac{2,500}{18}\%$

Simplify

$\frac{2,500}{18}\%=\frac{1,250}{9}\%$

Convert to mixed number

$\frac{1,250}{9}\%=\frac{1,242}{9}+\frac{8}{9}=138\frac{8}{9}\%$
