The choices should be B, C, and E. Hope this helps
If you are asking to simplify, this is what I got. Hope I was able to help
ABOUT SLOPE INTERCEPT FORM:
- y = mx + b
- m represents the slope
- b represents the y-intercept
You have to get y by itself:
5x + 8y = 16
-5x -5x
<u>8y = -5x + 15</u>
8 8
y = -5/8x + 15/8
OR
I you wants to simplify 15/8, it's this:
y = -5/8x +1.875
HI!!! Really really sorry if I'm incorrect...
Answer:
A=50
Step-by-step explanation:
5x10=50in
Answer:
79.1 ft
Step-by-step explanation:
Draw a vertical segment about 3 inches tall. Label the upper endpoint A and the lower endpoint B. That is the cell phone tower. Starting at point B, draw a horizontal segment 1 inch long to the right. Label the right endpoint C. Connect C to A with a segment.
Segment BC is 25 ft long. Segment AB is 75 ft long. Angle B is a right angle.
You are looking for the length of segment AC, the guy wire length.
Triangle ABC is a right triangle with right angle B.
Sides AB and BC are the legs, and side AC is the hypotenuse.
We can use the Pythagorean Theorem:
(leg1)^2 + (leg2)^2 = (hyp)^2
Let one leg be a, the other leg be b, and let the hypotenuse be c.
Then you have
a^2 + b^2 = c^2
We have a = 75 ft
b = 25 ft
We are looking for c, the length of the hypotenuse.
(75 ft)^2 + (25 ft)^2 = c^2
5625 ft^2 + 625 ft^2 = c^2
6250 ft^2 = c^2
c^2 = 6250 ft^2
Take the square root of both sides.
c = 79.0569... ft
Answer: 79.1 ft
