Answer: 110

<u>Turn each decimal into a Fraction</u>

12.1 = 12 1/10

0.11 = 11/100

<u>Turn 12 1/10 into an Improper Fraction</u>

Multiply 12×10 and get 120. Now add 1 and get 121.

12 1/10 = 121/10

<u>Do Keep Change Flip:</u>

Keep: 121/10

Change: ÷ into ×

Flip: 11/100 into 100/11

New Problem: 121/10×100/11

<u>Multiply</u>

121/10×100/11=12100/110

<u>Divide</u>

12100÷110=110

Use the Distance Formula to find the distance between D(2, 0) and E(8, 6).
Mazyrski [523]

Answer:

The answer is

<h2>6 \sqrt{2}  \:  \:  \: or \:  \:  \: 8.50 \:  \:  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question

The points are D(2, 0) and E(8, 6

The distance between them is

|DE|  =  \sqrt{ ({2 - 8})^{2}  +  ({0 - 6})^{2} }  \\  =  \sqrt{( { -  6})^{2}  + ( { - 6})^{2} }  \\  =  \sqrt{36 + 36}  \\  =  \sqrt{72}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 6 \sqrt{2}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  = 8.4852813

We have the final answer as

6 \sqrt{2}  \:  \:  \: or \:  \:  \: 8.50 \:  \:  \:  \: units

Hope this helps you

A triangle has sides with length of 11 feet 12 feet and 13 feet. Is it a right triangle
krek1111 [17]

Answer:

No

Step-by-step explanation:

It will be a right triangle if it follows Pyhthagoras Theorem . Where the sum of squares of two smaller sides is equal to the square of the 3rd side. Let's check ,

→ 11²+ 12² = 13²

→ 121 + 144 = 169

→ 265 ≠ 169

<h3>Hence the ∆ is not a right angled triangle </h3>
