Elenna [48]

Sean reads his book by what speed
This answer is quite unorthodox
LIke a speed question. We will find the amount of pages Sean read per hour or minutes if u want to convert

So speed of reading = amount of pages read/ time
= 144/3 hours or 144/3*60 minutes
=48 or 8/10 minutes

So time taken to complete his book at the same pace he is reading
amount of pages to read/speed of reading
=264/48 or 264*10/8
=5.5 hours or 330 minutes

hope u understood

Three packages of pens and one box of paper cost $26. Two packages of pens and 7 boxes of paper cost $49. How much does one box

algol13

Answer:

5 dollars

Step-by-step explanation:

Let's call the price of a package of pens n, and the cost of a box of paper r.

3n+r=26

2n+7r=49

Multiply the first equation by 7:

21n+7r=182

Subtract the second equation from the first:

19n=133

Divide both sides by 19 to isolate n:

n=7

Plug this back in to find the value of a box of paper:

3(7)+r=26

21+r=26

r=5

Hope this helps!

Compound interest <br> Plz help!!!

liraira [26]

Answer:

a) $A(t) = 17500(1.0053)^{12t}$

b) The balance after 8 years will be of $29,069.

Step-by-step explanation:

Compound interest:

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 year and t is the time in years for which the money is invested or borrowed.

Loan of $17,500 means that $P = 17500$
