50 would be greater than the exact answer.
Answer: 6.86 ft per second
Step-by-step explanation:
Both the top and the bottom of the ladder will be moving at the same time.
Given that the base of the ladder is pulled away from the wall at a rate of 2 feet per second when its base is 7 feet from the wall. Then the time will be
Speed = distance/time
2 = 7/t
t = 7/2 = 3.5 seconds
Using pythagorean theorem to get the length L of the wall
L^2 = 25^2 - 7^2
L = 24
The ladder will move down the length at the same time.
Rate = 24/3.5
Rate = 6.86 ft/s
Answer:
6 tenths
Step-by-step explanation:
The value of 8 in 5.18 is 0.08. The value of the 8 in 5.81 is 0.8.
X-5y=17 then x = 5y + 17
replace x = 5y + 17 into <span>-4x+y=8
</span>-4(5y + 17) +y = 8
-20y - 68 + y = 8
-19y = 8 + 68
-19y = 76
y = 76/-19
y = -4
x = 5y + 17
x = 5(-4) + 17
x = -20 + 17
x = 3
Answer: the order pair (3, -4)
