Answer:D
Step-by-step explanation:
If a 4 sided figure has 360°...for each side we add, we add 180°.
you have a 7 sided figure (360° + 3(180°) = 900°)
adding up your angles (781) and subtract it from 900 =
x = 119°
Answer:
4/9 probability you will get an even number
Step-by-step explanation:
The theoretical probability of spinning an even number is 4/9, since there are 4 even numbers in the spinner
Answer:
y = -3x + 7.
Step-by-step explanation:
First find the slope of the given line by converting to intercept form:
3x + y + 2 = 0
y = -3x - 2
So the slope is -3.
Then the line we want has a slope of -3 also (as it is parallel).
y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line:
m = -3, x1 = 1 and y1 = 4, so we have:
y - 4 = -3(x - 1)
y = -3x + 3 + 4
y = -3x + 7.
Answer:
d. 92.84
Step-by-step explanation:
The top edge overhangs the bottom edge by (39 -27)/2 = 6 ft on both ends. This makes the slant side have length
.. √((6 ft)^2 +(12 ft)^2) = 6√5 ft
Then the perimeter is
.. (39 +6√5 +27 +6√5) ft = 66 +12√5 ft
= 92.83 ft
