Answer:
The ladder reaches 4.8 ft up the wall
Step-by-step explanation:
5x-3y=16
3x-5y=-4
Multiply the first equation by 3; the second one by 5
15x-9y=48
15x-25y=-20
Eq 1 - Eq 2:
-9y+25y=48+20=68
16y=68
4y=17
y=17/4
5x-3y=16
5x-3×17/4=16
5x=16+51/4=(64+51)/4=115/4
x=115/4/5=23/4
x=23/4
Answer:
n=-5/2
Step-by-step explanation:
Start out by finding the area of the square.
a = 4²
a = 16
Since all we have to look at is 1/4 of this square, multiply the area by 1/4.
(16)1/4
4
The area of the triangle is 4.
Now we need the area of the circle.
a = πr²
Sub: a = π(2)²
a = π(4)
Since the portion of the circle that covers the triangle is 1/4 of the circle, subtract 1/4 of the area of the circle from the area of the circle.
a = 4 - 1/4(π(4))
a = 4 - 1/4π x 1
a = 4 - 1/4π
Now this is where it's supposed to go, considering the fact that π isn't given a value.
Normally, I'd use 3.14 for π, as the entire population would, and then it would be easy, but obviously that isn't an option.
Now this answer isn't up there, so my best option is to tell you it's most likely c, and I hope I'm right.
Uhh good luck I guess this math test is weird
