Hey there! :)

Area of triangles → (base × height) ÷ 2

The base and height are the 2 legs. You have to find the length of the other leg to find the area, using the Pythagorean Theorem.

a² + b² = c² → c² - a² = b²

c = 12
12² = 12 × 12 = 144

a = 10
10² = 10 × 10 = 100

144 - 100 = 44

√44 = 6.6
_____________________________________________________________

Area of triangles → (base × height) ÷ 2

Base: 10
Height: 6.6

6.6 × 10 = 66

66 ÷ 2 = 33

The area is 33 

Hope this helps :)

5.815 + 6.021 as a mixed number
tia_tia [17]
<h2><u>Answer</u></h2>

11 209/250

<h2><u>Explanation</u></h2>

5.815 + 6.021

First add the numbers the way they are.

          5.815

       <u> +6.021</u>

      <u>   11.836</u>

The whole number is 11.

11.836 = 11 + 0.836

0.836 = 836/1000

Dividing byy 4 we get,

0.836 = 836/1000 = 209/250

∴ 11.836  = 11 209/250

2x-10+x-6=2<br> combing like terms..
maria [59]
First you will combine the “x’s” so x+2x=3x then you would add 10 and 6 16 and subtract it to move it to the other side of the = so 2-16= -14 then you would divide 3x and -14 by 3 then there is your answer hope this helps

Whats the m.a.d. of 0, 3, 6, 9, 11, 13, 14? n=7
KatRina [158]

Answer:

4 2/7

Step-by-step explanation:

It is convenient to let a spreadsheet or graphing calculator do the tedious math for you. (See the attachment.)

_____

The sum of the numbers is 56, so their average is 56/7 = 8. Then the absolute deviations from average are ...

... 8, 5, 2, 1, 3, 5, 6

and the total of these is 30. The mean absolute deviation is this sum divided by the number of numbers, 7, so is ...

... 30/7 = 4 2/7

_____

<em>More about Absolute Deviation from Average</em>

"Absolute" here refers to the absolute value function, which drops the sign of a negative number. The absolute deviation of the data value 0 is ...

... |0 - 8| = |-8| = 8

For 3, it is ...

... |3 - 8| = |-5| = 5

What is 3/4 + 1/6 divided by 2/5 evaluated and simplified into a fraction?
BabaBlast [244]
3/4 + 1/6= the common denominator is 12
3x2/4x3 + 1x2/6x2= you must multiply the bottom values of the fraction to get 12 and whatever you multiply on the bottom you must do on the top as well
6/12 + 2/12= now you can add it
8/12
8/12 ÷ 2/5= you must multiply by the reciprocal
8x5/12x2=
40/36= this is the answer
10/9 (this is the simplified answer)
