(1+1/3)^2−2/9 I am about to have a mental breakdown, please somebody answer

Archy [21]

Answer:

$\frac{14}{9} = 1\frac{5}{9} \\\\1.5$

Step-by-step explanation:

$(1+1/3)^2-2/9\\\\= \left(1+\frac{1}{3}\right)^2-\frac{2}{9}\\\\\left(1+\frac{1}{3}\right)^2=\frac{4^2}{3^2}\\\\=\frac{4^2}{3^2}-\frac{2}{9}\\\\\frac{4^2}{3^2}=\frac{16}{9}\\\\=\frac{16}{9}-\frac{2}{9}\\\\\mathrm{Apply\:rule}\:\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}\\\\=\frac{16-2}{9}\\\\\mathrm{Subtract\:the\:numbers:}\:16-2=14\\=\frac{14}{9}$

If Zach has 4 times as many dimes as quarters and they have a combined value of 455 cents, how many of each coins does he have?

aliya0001 [1]

ANSWER:

Zach has 28 dimes and 7 quarters.

SOLUTION:

Given, Zach has 4 times as many dimes as quarters

And they have a combined value of 455 cents,

We need to find how many of each coins does he have?

Let, the number of dimes be x and number of quarters be y.

Then, x = 4y → (1)

Total combined value = 455 cents

x(value of one dime) + y(value of one quarter) = 455 cents

x(10 cents) + x(25 cents) = 455 cents

10x + 25y = 455 → (2)

Now, substitute (1) in (2)

10(4y) + 25y = 455

40x + 25y = 455

65y = 455

y = 7

substitute y value in (1)

x = 4(7) = 28

Hence, zach has 28 dimes and 7 quarters.

Jorge’s printer can print 24 pages in 15 minutes. How many pages can it print in 3/4 hour? In 1 hour?

Art [367]

Jorge's printer can print 72 pages in 3/4 hours and 96 pages in 1 hour.

Step-by-step explanation:

Given,

Pages printed in 15 minutes = 24 pages

15 minutes = $\frac{15}{60} = \frac{1}{4}\ hour$

Therefore;

$\frac{1}{4}\ hour = 24\ pages$

Multiplying both sides by 4

$4*\frac{1}{4}=24*4\\1\ hour = 96\ pages$

In 3/4 hours

$\frac{3}{4}\ hour = 96*\frac{3}{4}\\\\\frac{3}{4}\ hour = 72\ pages$

Jorge's printer can print 72 pages in 3/4 hours and 96 pages in 1 hour.
