Step-by-step explanation:
The base of the triangle is,
√(12²-5²)
= √119 = 10.9
The area of the triangle,
5×10.9/2
= 109/4 = 27.25 ≈ 27.3

Let x be the times in hours he mowed the lawn and y the time, in hours, he did chores Then
x + y = 3
also 352x + 136y = 570
From the first equation y = 3 - x, Plug this into second equation:-
352x + 136( 3 - x) = 570
216x = 570 - 136(3) = 162
x = 162/216 = 0.75
so he spent 0.75 hours (or 45 minutes) to mow the lawn.
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 =
