Answer:
If you had a bill of $45.00 and left an 18% tip then you would have left an $8.10 tip.
given,
1st term(a)= -2
2nd term (t2) =-12
3rd term (t3) =-60
4th term(t4)= -120
here common ratio (r)=t2/t1=t4/t3
or, -12/-2= -120/-60
or,6=2
hence,no -12, -60, -120 aren't in a geometric sequence because their common ratio aren't same.
Answer:
- 3 hours
- 1 hour 45 minutes
- 300 miles
Step-by-step explanation:
1. The trains are moving toward each other at a total speed of 50 +20 = 70 miles per hour. Together, they cover the 210 mile distance in ...
time = distance/speed
time = 210 mi/(70 mi/h) = 3 h
The trains collide after 3 hours.
__
2. The fly is closing with the freight train at a speed of 100 +20 = 120 miles per hour. Together, the fly and the train cover the initial 210 mile distance in ...
(210 mi)/(120 mi/h) = 7/4 h = 1 hour 45 minutes
The fly first meets the oncoming freight train after 1 h 45 min.
__
3. The fly is flying for all three hours before the trains collide, so, at 100 miles per hour, will fly 300 miles.
1/3 cup per servings mean 3 servings per cup
3 servings x 2 cups= 6 servings total
Answer:
60 degree
Step-by-step explanation:
E,A,D is a straight line .
Straight line=180 degree
100+20=120 -180=60
therefore X=60
