Answer:

$12.1 \div 0.11 \\ \frac{121}{10} \div \frac{11}{100} \\ \frac{121}{10} \ \times \frac{100}{11} \\ 11 \times 10 \\ 110$

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:

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>
