)D is the answer, Plese don't descriminate if I'm wrong.
Answer:
The number he thought of was 13
Step-by-step explanation:
Revers the problem
3.5 * 3 = 10.5
10.5 - 4 = 6.5
6.5 * 2 = 13
we know that
2pi radians (full circle) has an area of-----------------> 100pi
then
(2pi/5) radians----------------------------> X
X=(2pi/5)*100pi/2pi---------> 20pi units²
the answer is
20pi units²
Answer:
A and D, my sister had that question
Slope formula:
m = y2 - y1 / x2 - x1
Line QR: (2,8) (3,10)
m = 10 - 8 / 3 - 2 = 2 / 1 = 2
Line ST: (0,6) (-2,2)
m = 2 - 6 / -2 - 0 = -4/-2 = 2
<span>c. parallel because the slopes are the same</span>
