Answer:
The answer to your question is 2 hours
Step-by-step explanation:
Data
Juan speed = 4 mi/h
Cathy speed = 7 mi/h
t = x
Formula
speed = distance/time
Solve for distance
distance = speed x time
d = s x t
Distance travelled by Juan
d = 4t
Distance travelled by Juan in 1.5 h
d = 4(1.5)
d = 6 mi
total distance d = 6 + 4t
Distance travelled by Cathy
d = vt
d = 7t
Equal both equations
6 + 4t = 7t
Solve for t
6 = 7t - 4t
6 = 3t
6/3 = t
2 = t
Cathy wll catch up with Juan in 2 hours
Q + 5/9 = 1/6 . first subtract 5/9 on both sides
q = 1/6 - 5/9 . in order to subtract you need to find lcd
q = -7/17
hope this helps . give brainliest thanks
I think the answer is 43.8.
Answer:
RS = 12.2 in ⇒ answer (a)
Step-by-step explanation:
∵ m∠R = 78° , m∠T = 39° , TS = 19
∵ By using sin Rule:
∵ ST/sin∠R = RS/sin∠T
∴ 19/sin78 = RS/sin39
∴ RS = (19 × sin39) ÷ sin 78 = 12.2 in ⇒ answer (a)
