Answer:
42.5 (students that are on each bus)
Step-by-step explanation:
181 (students)-11 (students in cars) =170 students left
170(students left)÷4(buses)= 42.5(students that are on each bus)
Hope this help you
Answer:
60 miles per hour
Step-by-step explanation:
You divide 300 by 5 and you get 60. You always need to divide the upper part to the lower part to reach the distance in ONE UNIT OF TIME. There, you have 5 seconds, yet you need the distance in 1 second.
This all is assuming that the train moved at a constant speed, where
ACCELERATION = 0, which is pretty improbable for a train.
Answer:
It is D. 14
Step-by-step explanation:
Answer: the speed of the submarine is 5miles per hour
Step-by-step explanation:
The submarine left Hawaii two hours before the aircraft carrier.
Let x = the speed of the submarine
The aircraft carrier traveled at 25 mph for nine hours.
After this time the vessels were 280 miles apart. This means that when they became 280 miles apart, the aircraft carrier has travelled for 9 hours. If the submarine was ahead of the aircraft carrier with 2 hours, that means that the submarine travelled 9 + 2 = 11 hours
Distance travelled = speed × time
Distance travelled by submarine will be 11 × x = 11x miles per hour
Distance travelled by aircraft carrier will be 25 × 9 = 225 miles per hour
If they are 280 miles apart, this would be their total distance. Therefore,
225 + 11x = 280
11x = 280 - 225 = 55
x = 55/11 = 5miles per hour
Find slope
slope for points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
(-4,3), (4,5)
(5-3)/(4-(-4))=2/(4+4)=2/8=1/4
slope=1/4
y=mx+b
m=slope
b=yint
solve for yint
input a point
(4,5)
x=4
y=5
5=(1/4)4+b
5=1+b
minus 1
4=b
y=1/4x+4
