Answer:
c
Step-by-step explanation:
(5y - 1) = 4y + (9y - 4) = 5y
2y > .75
Answer:
m=7
Step-by-step explanation:
If you plot 3,12 on a graph and go move to the
left one and up one untill the x axis is zero you
will land on five. so the amount the tub started
with is 15
As you can probably tell, this is a 30, 60, 90 triangle. That means the degree measures are 30, 60, and 90. These are special triangles. For every 30, 60, 90 triangle in the world, the shorter leg (in your case, x) is ALWAYS two times shorter than the hypotenuse (6). 6/2=3, so x=3. Also, the longer leg for a 30, 60, 90 triangle is always equal to the shorter leg times the square root of 3. So, 3 times the square root of 3 is about 5.2. So, y=5.2. Hope it helps!
Answer:
44 ft
Step-by-step explanation:
There are a couple of ways this can be worked. You could find the height of the tower, then use the Pythagorean theorem to find the wire length.
Or, you can find the wire length for the smaller triangle and scale up the result to the larger triangle. We choose this method.
The length of the wire (w) from the stake to the top of the pole is given by the Pythagorean theorem:
w² = 4² +7² = 16 +49 = 65
w = √65 . . . . . . take the square root
The base of the larger triangle is 18+4 = 22. The scale factor from the smaller to larger triangle is the ratio of base lengths: 22/4 = 11/2
The overall length of the guy wire is this ratio times "w" ...
(11/2)√65 ≈ 44 . . . . feet
