$\large\boxed{x=20}$

Step-by-step explanation:

The whole triangle and small triangle are similar (AA). Therefore the sides are in proportion:

$(5x+10+10)/(10)=(121+11)/(11)$

$\drac{5x+20}{10}=(132)/(11)$ cross multiply

$11(5x+20)=(10)(132)$ use distributive property

$(11)(5x)+(11)(20)=1320$

$55x+220=1320$ subtract 220 from both sides

$55x=1100$ divide both sides by 55

$x=20$

Answers

Answer:

Step-by-step explanation:

You did leave out a 4 under the r: 1.1063 = (1+r/4)^20

So you'd do both sides to the 1/20 power since 20 • 1/20 = 1

(1.1063) ^ (1/20) = 1 + r/4

Then subtract 1, and multiply by 4

4•[1.1063 ^ (1/20) - 1) = r

What is the MAD of the data set?

{13, 6, 3, 7, 11}

Answers

13 + 6 + 3 + 7 + 11 = 40

40 ÷ 5 = 8

13 - 8 = 5
6 - 8 = |-2| = 2
3 - 8 = |-5| = 5
7 - 8 = |-1| = 1
11 - 8 = 3

5, 2, 5, 1, 3

5 + 2 + 5 + 1 + 3 = 16

16 ÷ 5 = 3.2

MAD = 3.2

Answer:

MAD = 3.2

Step-by-step explanation:

13 + 6 + 3 + 7 + 11 = 40

40 ÷ 5 = 8

13 - 8 = 5

6 - 8 = |-2| = 2

3 - 8 = |-5| = 5

7 - 8 = |-1| = 1

11 - 8 = 3

5, 2, 5, 1, 3

5 + 2 + 5 + 1 + 3 = 16

16 ÷ 5 = 3.2

MAD = 3.2

Answers

We need to follow PEMDAS.

We need to do the division before we can do the subtract (which becomes into addition because of the signs).

12 - 16/-4

12 - (-4)

12 + 4

16

Your final answer is C. 16.
