Answer:
126 degrees.
Step-by-step explanation:
The number of degrees in a circular spinner = 360.
So the central angle for success will be 35% of 360 degrees.
This = 35 * 360 / 100
= 126.
Answer:
Option D. − 8/5
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
we have the points
(−1, 7) and (4, −1)
substitute in the formula
9514 1404 393
Answer:
(x, y) = (7, -1)
Step-by-step explanation:
The expression for x makes it easy to use that for substitution.
3(-7y) +y = 20
-20y = 20 . . . . . collect terms
y = -1 . . . . . . . . . divide by -20
-7(-1) = x = 7 . . . use y in the second equation to find x
The solution is (x, y) = (7, -1).
Answer:
Option D
Step-by-step explanation:
a^2 + b^2 = c^2
5^2+b^2=9^2
25+b^2=81
b^2=56
b=2√14
