Simplest way to do this:
number of books= 120
percentage represented by 120= 100%
increase current percent by 55%= 155%

: . 55% increase = original number of books * (155%)
= 120 * (155/100)
= 186

ANSWER
$0.073 \% = 0.00073$

EXPLANATION

Recall that,

$\% = \frac{1}{100}$

That is why
$100\%$
is equivalent to
$1.$

This implies that,

$0.073\% = 0.073 \times \frac{1}{100}$

This is the same as,

$0.073\% = \frac{0.073}{100}$

When we are dividing by
$100$
we move the decimal point backwards two times.

This implies that,

$0.073\% = 0.00073$

Using the Pythagorean theorem, find the length of c if a = 14 * the square root of 3 and b = 34

ANEK [815]

If c is the hypotenuse, we have

$c=\sqrt{a^2+b^2}=\sqrt{(14\sqrt{3})^2+34^2}=\sqrt{588+1156}=\sqrt{1744}$

If instead b is the hypothenuse, you have

$c=\sqrt{b^2-a^2}=\sqrt{1156-588}=\sqrt{568}$

The school that Stefan goes to is selling tickets to a choral performance on the first day of ticket sales the school sold three

Serggg [28]

The price of 1 senior citizen ticket is $ 8

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

Let "x" be the price of 1 senior citizen ticket

Let "y" be the price of 1 child ticket

<em><u>The school sold three senior citizen tickets and one child ticket for a total of $38</u></em>

Therefore, we frame a equation as:

three senior citizen tickets x price of 1 senior citizen ticket + one child ticket x price of 1 child ticket = 38

$3 \times x + 1 \times y = 38$

3x + y = 38 --------- eqn 1

<em><u>The school took an $52 on the second day by selling three senior citizen tickets and two child tickets</u></em>

Therefore, we frame a equation as:

three senior citizen tickets x price of 1 senior citizen ticket + two child ticket x price of 1 child ticket = 52

$3 \times x + 2 \times y = 52$

3x + 2y = 52 ---------- eqn 2

<em><u>Solve eqn 1 and eqn 2</u></em>

<em><u>Subtract eqn 1 from eqn 2</u></em>

3x + 2y - 3x - y = 52 - 38

<h3>y = 14</h3>

<em><u>Substitute y = 14 in eqn 1</u></em>

3x + y = 38

3x + 14 = 38

3x = 24

<h3>x = 8</h3>

Thus the price of 1 senior citizen ticket is $ 8
