To solve this, you would do:

x + 75% * x = 35

7/4 * x = 35

x = 20

A number increased by 75% is the number +75% of the number, or the number plus 0.75 of the number, or 1.75 of the number, or 1.75x (with the number being x). We can do this because a percent is per 100 and we already have 1.0 of the number (1x is equal to x). Since we know that 1.75x is equal to 35, we can set up an equation.

1.75x = 35

Now, we want to get x by itself. We can do this by multiplying both sides by the reciprocal of x.

1.75 * 1/1.75x = 35/1.75

x = 20

That means that 20, increased by 75% is 35.

Step-by-step explanation:

what is the problem ? what needs to be done ?

all that you are showing here is the definition of a number range.

it means all numbers, for which 1.3 is smaller or equal.

in short, all numbers that are greater or equal to 1.3.

The infinite geometric series S=1+( 2/3 )+( 2/3 )^ 2 +( 2/3 )^ 3 .... equal to:

weqwewe [10]

SOLUTION

The question simply means that we should find the sum to infinity of the geometric series.

The formula of sum to infinity of a geometric serie is given by

$S_{\infty}=\frac{a}{1-r}$

Where

$\begin{gathered} S_{\infty}\text{ is the sum to infinity} \\ \\ a\text{ is the first term = 1} \\ \\ r\text{ is the common ratio = }\frac{2}{3} \end{gathered}$

So, this becomes

$\begin{gathered} S_{\infty}=\frac{a}{1-r} \\ \\ S_{\infty}=\frac{1}{1-\frac{2}{3}} \\ \\ S_{\infty}=\frac{1}{\frac{3-2}{3}} \\ \\ S_{\infty}=\frac{1}{\frac{1}{3}} \\ \\ S_{\infty}=3 \end{gathered}$

Therefore, option b is the correct answer
