Answer:
Step-by-step explanation:
x-y=5
-x+y=5
or x-y=-5
so it is a system of two parallel lines.
so no solution.
or they do not intersect atmany point.
So I took the test and my teacher said to label all of the degrees so
angle 1,3,5,7,9,11,13,15 all = 95 degrees
angle 2,4,6,8,10,12,14,16 all = 85 degrees
I know 1 and 3 are vertical angles
3 and 8 are same side interior angle
4 and 14 alternate interior angles
6 and 12 are alternate exterior angles
13 and 9 are corresponding angles
4 and 7 are same side interior angles
I believe these are correct but you might want to double check with some other source
the correct answers are 3, 4 and 5
Answer:
28 cm
Step-by-step explanation:
Area =radius^2 pi
784 pi = radius^2 pi
radius^2 = 784
radius = √784
radius = 28 cm
Answer:
$1155
Step-by-step explanation:
Richard earns $10.50 per hour and he worked for 275 hours.
First find out the total amount he earns.
Total = 275 hours x $10.50 = $2887.50
40% of the earnings go to saving.
Now we find out how much is 40% of the earnings.
Saving = 40% of $2887.50 = 0.4 x 2887.5 = $1155
