Answer:
Percent increase is 17.6%
We still have to pay 7.50 with the coupon
Step-by-step explanation:
Percent increase = (new- original)/original *100%
= (10-8.5)/8.5 * 100%
= 1.5/8.5 * 100%
= 17.6470588%
Round to the nearest tenth
17.6%
This is an increase since the cost went up.
If we have 25% off, we still have to pay (100%-25%) = 75%
10 *.75 = 7.50
We still have to pay 7.50 with the coupon
Step-by-step explanation:
5x - 15 we multiply the barclet value by 5
Answer: 20.833mph.
Step-by-step explanation:
Using the motion Formula,
speed = distance/time.
This means:
distance = speed * time.
To find the value of "s" in the question, we have to calculate the distance both trains travelled in terms of "s" and sum it to give us 300miles.
For train A,
Speed = S miles per hour
time taken to reach current position= 7hours.
Hence, the distance travelled by train A
Distance A = 7s.
For train B,
Speed= (S + 10)miles per hour.
time taken to reach current position= 5hours (since train B left two hours after the departure of train A)
Distance = speed * time
Distance B = (S + 10) * 5
Distance B = 5s + 50.
Hence, adding both distance to sum up to 300miles, it becomes:
300 = 7s + 5s + 50
300-50 = 12s
250 = 12s
s = 20.833mph.
