Answer:
3.605 ft is the answer.
Step-by-step explanation:
Applying Pythagoras theorem,
a^2 + b^2 = c^2
2^2 + 3^2 = c^2
4 + 9 = c^2
13 = c^2
3.605 = c
therefore, the answer is 3.605.

Answer:
x=-2 y=3
Step-by-step explanation:
The substitution is basically given to you. Exchange x from the second equation with y-5
Once that is done and you combine the parentheses you get:
2y-10+y=-1
Add 10 on both sides of the equal sign
You get:
3y=9
Divide both sides by 3
You get:
y=3
To check your work you can substitute y in the second equation with 3 and solve it that way to get x=-2 (x equals negative two)
I agree with the other person that this is 25% error
Answer:
d) 35ft
e) 6 seconds
f) 250°
Step-by-step explanation:
If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.
36 secs = 360°
⇒ 1 sec = 360/36 = 10°
d) After 9 seconds, it has turned:
9 x 10 = 90°
Therefore, it will be 15 + 20 = 35ft from the wall
e) 60° = 6 seconds
f) 25 seconds = 25 x 10 = 250°
