These lines are perpendicular!
y = x
y = -x–2
The slopes are reciprocals of each other, so they are perpendicular.
Answer:
y = 55
Step-by-step explanation:
The sum of the angles of a triangle are 180
40 + y+30 + y = 180
Combine like terms
70 +2y = 180
Subtract 70 from each side
2y = 180-70
2y = 110
Divide each side by 2
2y/2 = 110/2
y = 55
<u>Given</u>:
Given that Jasmine rides her bike 9 miles in 50 minutes.
We need to determine the speed per hour.
<u>Time per hour:</u>
The time taken is 50 minutes. We need to convert minutes into hours.
Thus, we have;

Thus, the time taken to cover 9 miles is 
<u>Speed:</u>
The speed can be determined using the formula,

Substituting the values, we have;

Simplifying, we get;



Thus, Jasmine's speed is 10.8 miles per hour.
So the formula you have to do is A= (pie)(radius)(squared)
divide 6.7 by 2 to find the radius which is 3.35
now do 3.35 * 3.35 ( we are squaring it) which = 11.225
now 11.225 times PIE is 35.264377537
so the answer is 35.264377537
hope that helped!
