Answer:
e. 10√30
Step-by-step explanation:
In this right triangle geometry, all of the right triangles are similar. This means that the ratio of long side to hypotenuse is the same for all triangles:
x/(10+50) = 50/x
Multiplying by 60x, we have ...
x^2 = 3000
x = 10√30 . . . . . take the square root. Matches choice E.

<em>Comment on estimating</em>
You're looking for x. Examining the figure, you see that x is the long side of the triangle with hypotenuse 10+50=60, so it will be shorter than that value. x is also the hypotenuse of the triangle with long side 50. So, x will be longer than 50.
The only answer choice with a value between 50 and 60 is choice E.
You don't even need to know how to find x. You only need to know that the hypotenuse is the longest side in a right triangle.
Answer:
a) (1|4)
b) 3
c) 3
Step-by-step explanation:
the turning point is when the graph is at it's highest or lowest point, so here it is 1 for x and 4 for y. I'm not sure if i did b and c right but i think i did
the answer is 2
there are 13 days, 6x2=12. so the answer is 2.
Answer:
y = 2x+5
Step-by-step explanation:
Add y on both sides, this cancels out the y on the left side
add 2x and add 5 on both sides, this cancels out the -2x and the -5 on the left side.
<u>OR </u>
Divide/Multiply both sides by -1, as it will cancel out the negatives as two negatives make a positive.
If you needed a value for y, more info is needed.
hope this helps (:
