Answer:

x=10

Step-by-step explanation:

In order to solve this equation we must break it down. This question is going to require the Pythagorean theorem a^{2} +b^{2}=c^{2}. To use this we need a right triangle which happens to be half of the triangle shown. Now we can plug in the numbers.

7^{2}+\frac{1}{2} x^{2} =\sqrt{74}^{2}

49+\frac{1}{2} x^{2} =74

\frac{1}{2} x^{2} =25

\frac{1}{2} x=5

x=10

This ends in x equaling 10. I hope this helps you!

Piece made in 32min factory cut the time by 8% then cut time by 5% how long does it take to make the piece now in min
DiKsa [7]

Answer:

27.968 mins

Step-by-step explanation:

1) we need to find 8% of 32:

32*0.08=2.56

so 8% of 32 is 2.56 mins.

we need to subtract 2.56 by 32 since its says the times was cut by 8%

so

32-2.56=29.44

now 5% of 29.44:

29.44*0.05=1.472

1.472 mins

so

29.44-1.472=27.968

Hope this helps!
