Answer:
Total distance Jason cycled = 20 miles
Step-by-step explanation:
Distance covered in first 2 hours = 2( 7.5)
=15
Distance covered in the 3rd hour = 15/3
= 5
Dividing by 3 because the distance covered in the 3rd hour is 1/4 of the distance covered in first two hours. By dividing by 3 we will get 1/4 of the distance
Total Distance = Distance covered in first two hours
+ Distance covered in the 3rd hour
=15 + 5
Total Distance = 20
Answer:
r = 4
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 5
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, r ) and (x₂, y₂ ) = (8, 9)
m = 
= 
= 9 - r = 5 ( subtract 9 from both sides )
- r = - 4 ( multiply both sides by - 1 )
r = 4

Answer:
<em>A. 35 deg</em>
Step-by-step explanation:
The triangles are congruent bu HL.
m<RCD = m<PCD = 35 deg
Answer:
-62/23 degrees per hour
Step-by-step explanation:
Do this by dividing the total change in temperature (-15 1/2 degrees) by the total elapsed time (5 3/4 hrs):
-31/2 degrees -62/4 degrees Note: convert 31/2 to 62/4
--------------------- = ------------------------ = -62/23 degrees per hour
23/4 hrs 23/4 hrs
