Answer:

431.775 ft

Step-by-step explanation:

So basically we should first find the area of the rectangles which is 28 ft * 15 ft, which you get 420. Next for the semicircle, the diameter is 15 but we need the radius so you divide that by 2 to get 7.5 as the radius. Then u multiply 7.5 * π, or 3.14 to get 23.55. But since its a semicircle, or half a circle we divide 23.55 by 2 which is 11.775. Then we just add the results which is 420 ft and 11.755 ft to get a total area of 431.775 ft.

-Hope this helped!

Solve for p. i = prt p = i-rt p = (rt)/i p = i/(rt)

andrezito [222]

Answer:

$\sf p = \dfrac{i}{rt}$

Step-by-step explanation:

Solve for p:

$\longrightarrow$ i = prt

i = prt is equivalent to prt = i:

$\longrightarrow$ prt = i

Divide both sides by rt:

$\longrightarrow$ $\sf \dfrac{prt}{rt} = \dfrac{i}{rt}$

$\sf \dfrac{prt}{rt} = p:$

$\longrightarrow$ $\sf p = \dfrac{i}{rt}$

Can someone please help convert these so they have the same denominator??

ratelena [41]

The LCM of the denominators is 120. In other words, the denominators can multiply to 120.

3 * 40 = 120

40 * 2 = 80

Tigers: P = 80/120

24 * 5 = 120

24 * 4 = 96

Redbirds: P = 96/120

8 * 15 = 120

3 * 15 = 45

Bulldogs P = 45/120

60 * 2 = 120

60 * 1 = 60

Titans P = 60/120

Answer

Tigers: P = 80/120

Redbirds: P = 96/120

Bulldogs: P = 45/120

Titans: P = 60/120
