Answer:

36%

Step-by-step explanation:

line up $ and % data like this:

$3.79 represents X%

cross multiply

X*2.79 = 3.79*100

divide both sides by 2.79

X= 3.79*100 / 2.79 ≈ 136%

so it increased 36%

The number square root of 3 goes on forever with no repeating pattern therefore it is rational?

vova2212 [387]

Answer:

False

Step-by-step explanation:

A number that can expressed as $\frac{p}{q}$ ,

Where, p and q are integers such that q ≠ 0, is called a rational number.

Also, a decimal number with repeating pattern is a rational number,

( for eg : 0.333.... = $\frac{3}{9}$ )

Since,

√3 = 1.73205080757.....

∴ There is no repeating pattern

Thus, √3 is not a rational number.

Given statement is FALSE.
