Write an inequality for this situation
Rainbow [258]

Answer:  E \ge 31

Reason:

"at least 31 points" means "31 or more".

So either E = 31 or E > 31 (meaning Embiid scored 31 points or he scored more than 31 points).

Choice A looks like the closest match assuming the inequality sign is \ge

Saying E > 31 instead of E \ge 31 would be false because it leaves out the case E = 31.

What are the lateral area and the surface of the cone shown below?
Ierofanga [76]
\bf \textit{lateral surface area of a cone}\\\\&#10;LA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}~~&#10;\begin{cases}&#10;r=radius\\&#10;h=height\\&#10;-------\\&#10;r=11\\&#10;\stackrel{slant~height}{\sqrt{r^2+h^2}}=24&#10;\end{cases}\implies LA=\pi (11)(24)&#10;\\\\\\&#10;\boxed{LA=264\pi }\\\\&#10;-------------------------------

\bf \textit{total surface area of a cone}\\\\&#10;SA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}+\pi r^2~~&#10;\begin{cases}&#10;r=radius\\&#10;h=height\\&#10;-------\\&#10;r=11\\&#10;\stackrel{slant~height}{\sqrt{r^2+h^2}}=24&#10;\end{cases}&#10;\\\\\\&#10;SA=\pi (11)(24)+\pi (11)^2\implies SA=264\pi +121\pi &#10;\\\\\\&#10;\boxed{SA=385\pi }

The question is in the jpg.
dexar [7]
First, you need to find the height, in which it says “a height that’s half the length of the longer base side. Can you guess what that is between 7 and 5? It is 7. And you would find half of that which is 3.5. Now you know the height is 3.5. The formula to find a rectangular pyramid's volume is lwh/3 which you would do 7 * 5 * 3.5, which is equal to 122.5, and then you would divide that by 3, which is 40.833 which would round to 40.8, so there is your answer.
It is 40.8 units^3
