An image showing the step by step solution is attached.
Answer:
As there is one math problem over there.
Lets see the question first:
It says that "A hair dryer is rated ,if you use the dryer for .How much electric energy do you use ?"
Final answer = Electic energy
Step-by-step explanation:
Electrical Energy .
The total amount of electrical energy used depends on the total power used by the electrical device and the total time they are used for.
So we have been given the power of the hair dryer
Now the time it has been use for
To calculate electric energy we will multiply both the terms.
Electric energy
So electric energy used for the hairdryer is =
<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:
True
