The major and minor axes of an ellipse are 25 inches and 4 inches in length. What is the area of the ellipse?

Nostrana [21]

Answer:

Therefore, the area of the ellipse is:

Area = 78.5 inches

Step-by-step explanation:

The formula to find the area of the ellipse is

$\:a\:\times \:b\:\times \:\pi$

The major axis of an ellipse = 25 inches

The minor axis of an ellipse = 4 inches

The value of a = major axis/2 = 25/2 = 12.5 inches

The value of b = minor axis/2 = 4/2 = 2 inches

Thus

The area of the ellipse:

Area = $\:a\:\times \:b\:\times \:\pi$

$=\:12.5\:\times\:2\:\times\:\pi$

$=25\pi$

$=78.5$ inches ∵ $\pi =3.14$

Therefore, the area of the ellipse is:

Area = 78.5 inches

Two angry children 450 feet apart are headed straight towards each other—one at 15 feet per second and the other at 6 feet per s

sergiy2304 [10]

If the amount of time is x seconds, then 15*x is the amount ran by one child and 6*x is the amount ran for the other child due to that they add 15 or 6 feet for each second. In addition, since they are 450 feet apart, 15x+6x=450=21x. Dividing both sides by 21, we get x=around 21.4 seconds. Since the mother is always between them, when those two meet is when the three meet. Therefore, she runs 20* around 21.4= around 428.57 feet

James buys a shirt and a pair of socks on sale for 25% off.

bixtya [17]

Answer:

$12

Step-by-step explanation:

24 x 0.25 = 6 ----- The 6 represents how much money is being taken off the original price

24 - 6 = 18 ---- the price of the shirt after sale was $18

24 - 18 = 6 ---- after the sale the socks were $6

6 + 6 = 12 ---- the original price of the socks

hope this helps!
