Find the area of a circle whose area equals the half of the sum of the areas of two circles with radil 2 and 3.
OlgaM077 [116]

Step-by-step explanation:

step 1. a circle with r = 2 has area of (pi)r^2 = (pi)(4) = 4pi

step 2. a circle with r = 3 has area of (pi)r^2 = (pi)(9) = 9pi

step 3. the area, A, of a circle is half the sum of the area of the circles with r = 2 and r = 3

step 4. A = (4pi + 9pi)/2 = 13pi/2 = 6.5(pi).

step 5. the answer is not 6.5 but is 6.5(pi) or 6.5 times pi.

Tv Is 40 inches in length and 24 inches in width how tall is it
Sedaia [141]

Answer

<em>TV screens are measured on the diagonal  </em>

<em>. In this specific case the TV is shaped like a rectangle , whose diagonal is 40 i n c h e s and its width is 24 i n c h e s : w = </em>

<em>24 i n d = 40 i n  </em>

<em>Then , the sides of the rectangle and its diagonal form a right triangle .  </em>

<em>Therefore , we can determine the height ( l )  </em>

<em>if we can apply the Pythagorean theorem: d 2 = l 2 + w 2  </em>

<em>So , solving for l : l = √ d 2 − w 2  </em>

<em>Thus , substituting: l = √ ( 40 ) 2 − ( 24 ) 2  </em>

<em>Simplifying: d = √ 1024 = 32 i n  </em>

<em>Therefore  </em>

<em>, the height of the TV is:  </em>

<em>32 i n </em>

Mary lost 30 pounds. Before her diet she weighed 180 pounds. What is the percent of change.
Lelu [443]

Answer:

percentage change= 500%

Step-by-step explanation:

After diet the weight reduced = 30 pounds

Before diet her weight = 180 pounds

percentage change = { (180 - 30) ÷ 30 } × 100

                             =  ( 150 ÷ 30) × 100

                              = 5 × 100

                               = 500 %

∴percentage change= 500%
