<h3>The lateral area for the pyramid with the equilateral base is 144 square units</h3>
<em><u>Solution:</u></em>
The given pyramid has 3 lateral triangular side
The figure is attached below
Base of triangle = 12 unit
<em><u>Find the perpendicular</u></em>
By Pythagoras theorem
Therefore,
<em><u>Find the lateral surface area of 1 triangle</u></em>
<em><u>Thus, lateral surface area of 3 triangle is:</u></em>
3 x 48 = 144
Thus lateral area for the pyramid with the equilateral base is 144 square units

Answer:
$250
Step-by-step explanation:
You can imagine the price of 212.5 to be 85% of the original price (100 - 15), so to do this, an easy way to find 100% is to simply divide the amount by the percentage:
Amount ÷
Simply plug the values in:
212.50 ÷ (
= 250
So the price of the tablet before markdown was $250!

Answer:
4.8 x 10^9
Step-by-step explanation:
E9 is 10 raised to the power of 9
Scientific notation requires you to write a number from 1 to 10 then multiply it by 10 raised to a number x.
In this case:
4.8E9 = 4,800,000,000
Number between 1 and 10 = 4.8
Number of zeroes = 8 but because you have to multiply 4.8 times 10 to get 48 the answer is 4.8 x 10^9... so one extra 10... 1+8=9
Hope you understand
