By the Pythagorean Theorem, the hypotenuse squared is equal to the sum of the sides squared...
h^2=x^2+y^2
We are told that y=x+20 and h=24 so
x^2+(x+20)^2=24^2
x^2+x^2+40x+400=576
2x^2+40x+400=576
2x^2+40x=176
x^2+20x=88
x^2+20x+100=188
(x+10)^2=188
x+10=±√188
x=-10±√188, x>0 so
x=-10+√188 ft
y=10+√188 ft
If you want approximations...
x≈3.71 ft
y≈23.71 ft
Multiply 2*(-75) = -150
Since you need the absolute value... turn it positive
The answer is 150
Answer:
3
Step-by-step explanation:
As in the first set of numbers
4,5,2 are successes.
but in the next set of numbers
5 is right before a fail.
but then straight passes after that
(50 / 10) x 2 = 10 students have black hair
(50 / 10) x 1 = 5 students have blonde hair
(50 / 10) x 7 = 35 students have brown hair
