-Given Hypotenuse=22 ft and the base length is 11 feet.

-We apply the Pythagorean theorem to find the height:

$h^2+b^2=H^2\\\\h=\sqrt{22^2-11^2}\\\\=19.05\ feet$

Hence, the stair's height is 19.05 ft

kifflom [539]

Answer: £ 8

Step-by-step explanation:

Total hours Lena works from Monday to Friday = 34 hours

Hours she works on Saturdays = 4

Overtime rate of Saturday = 1.5 times her normal rate

Let x be the normal rate.

Then , Her total earning = $34 x + 4 \times(1.5x) =34x+6x=40x$

Since her total earnings for week = £ 320

So,

$320=40x\\\\\Rightarrow\ x=\dfrac{320}{40}\\\\\Rightarrow\ x=8$

Thus, her normal rate of pay per hour = £ 8

Brody added a fraction to 5/6 to get 31/30. Use the equation a/b + c/d = (ad +bc)/ bd to find the fraction he added

sashaice [31]

The fraction he added is 6/30, or 1/5.
I'm not 100% sure about the equation you want me to use but I did the work this way:

5/6+x/30=31/30 (the denominator has to equal 30 because you are adding. You need a common denominator which is why you need to change 5/6. We can label the numerator as a hidden value x)

25/30+x=31/30

You can then work backwards and basically subtract 25 from 31 and get 6; so x=6
