Find the square root of 3.6 upto 2 decimal places. *With Solution I need*
almond37 [142]

Answer:

The square root is 1.90

Step-by-step explanation:

Given

x = \sqrt{3.6}

Required

Find x

Express 3.6 as 36/10

So, we have:

x = \frac{\sqrt{36}}{\sqrt{10}}

This gives

x = \frac{6}{\sqrt{10}}

Rationalize

x = \frac{6}{\sqrt{10}}*\frac{\sqrt{10}}{\sqrt{10}}

x = \frac{6\sqrt{10}}{10}

Using a calculator

\sqrt{10} \approx 3.16

So, we have:

x = \frac{6*3.16}{10}

x = \frac{18.96}{10}

x = 1.896

Approximate

x = 1.90

Three consecutive even numbers have a sum between 84 and 96.
ELEN [110]

Answer:

a. 84 < n + (n + 2) + (n + 4) < 96

b. 26 < n < 30


Step-by-step explanation:

Let n = 1st number

n+2   2nd  even number

n+4 = 3rd even number

The sum of these 3 numbers is

n+n+2+n+4

It must be between 84 and 96  (it does not include this 84 and 96)

84< n+n+2+n+4 < 96


Now we need to solve this

Combine like terms

84 < 3n +6< 96

Subtract 6 from all sides

84 -6 < 3n+6-6 < 96 -6

78 < 3n < 90

Divide all sides by 3

78/3 < 3n/3 < 90/3

26 < n< 30

nataly862011 [7]

Answer:

D

Step-by-step explanation:

If you ask questions while their speaking it shows that you are paying attention to them. Avoiding eye contact could mean your thinking about something else or you aren't interested. Interrupting them is just being disrespectful. Leaning towards them doesn't really do anything other than you moving.
