svetoff [14.1K]

Answer:

4 + 6 \sqrt{2}

Step-by-step explanation:

\sqrt{32}  +  \sqrt{16}  +  \sqrt{8}

\sqrt{32}  =  \sqrt{4 \times 4 \times 2}  =  4\sqrt{2}

\sqrt{16}  =  \sqrt{4 \times 4}  = 4

\sqrt{8}  =  \sqrt{2 \times 2 \times 2}  = 2 \sqrt{2}

4 +  4\sqrt{2}  + 2 \sqrt{2}  = 4 + 6 \sqrt{2}

Landon used a semicirce, a rectangle, and a right triangle to form the figure shown.
ankoles [38]
Area of rectangle= base x height
6x4=24

Area of triangle= 0.5 base x height
We have the height but we don’t have the base, to calculate the base we subtract 10-6 which equals to 4
0.5 x 4 x4 =8

Area of a semicircle= o.5 x pi x r^2
We have the diameter and to find the radius we divide it by 2
4/2 = 2
0.5 x pi(or 3.14) x 2^2
=6.28
Total area = 24 + 8+ 6.28 =38.28cm^2

16 ÷ 22 + (6 x 2) - 8
stepladder [879]
I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)

First I did what’s inside the parentheses, (6x2) and got 12.

Then I divided 16 by 22 and received 0.72.

I added 0.72 with 12 and the result was 12.72.

Last step was to subtract 12.72 - 8 and that equals 4.72

Aleah enjoys swimming and skating with her friends. She has a budget where she spends no more than $80 a month for her activitie
kari74 [83]
<span>a) define the variables
The variables are x and y ; x can represent the number of times Aleah goes swimming ; while y can represents the number of times Aleah goes skating.

b) are there any restrictions on the variables? 
The total sum of both activities must be equal or less than $80 a month

c) write a linear inequality to represent this situation
</span><span>Swimming costs $5 each time and skating costs $4 each time. No more than $80 a month.

5x + 4y <u><</u> 80
