A pyramid has a square base with sides 100 feet long. The original height was 75 feet.

viva [34]

Step-by-step explanation:

Step 1: Find the volume of the original pyramid

$V = a^2*\frac{h}{3}$

$V=(100)^2*\frac{75}{3}$

$V=10000*25$

$V=250000$

Step 2: Find the volume of the cut off

$V=(20)^2*\frac{15}{3}$

$V = 400*5$

$V=2000$

Step 3: Find the percent that still remains

$250000-2000$

$248000$

$248000 / 250000$

$0.992*100$

$99.2$

Answer: 99.2%

Ronin kicks a ball over the gate of the first floor balcony. The function h(t)=-36t^2+288t+9 can be used to model the height of

ale4655 [162]

Answer: 4 seconds

Step-by-step explanation:

Given: The function $h(t)=-36t^2+288t+9$ can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.

Differentiate the given function with respect to t , we get

$h'(t)=-36(2)t+288=-72t+288$

Put h'(t)=0

$\Rightarrow\ -72t+288=0\Rightarrow\ t=\dfrac{288}{72}\\\\\Rightarrow\ t=4$

Also, $h''(t)=-72$

By second derivative test, h(t) is maximum at t=4.

Hence, the time in Devon which the ball reaches it maximum height = 4 seconds

If there are 144 fruits in a box. And 1/8 are red apples and 1/4 are green apples and the rest are oranges. Than how many orange

Leviafan [203]

1/8 of 144= 18 (red apples). 1/4 of 144= 36 (green apples). Oranges = 36+18= 54, equal to 144-54= 90. Therefore, there are 90 oranges, and this is equal to 90/144, or 45/ 72 or 15/24 or 5/8. Hope this helps :)
