1. 5 hours
2. 4 hours
Reason:
Formula for speed is speed = , if you want to find time, then take distance / speed, which will equal to 100 / 20 = 5 hours, and the same with 2.
So
#1
#2
Cost of 7 gallons=$24.50
Cost of 1 gallon=24.50/7=3.5
Cost of 15 gallons=15*3.5=52.5
Cost of 15 gallons will be $52.5
For 1 flavor there are 9 topping
Therefore, for 5 different flavors there will be 5*9 choices
No of choices= 5*9
=45
The total nom of code that can be used is equal to 5+3 = 8
y=2x+15
where y=Value of coin
x=Age in years
Value of coin after 19 years=2*19+15
=$53
Therefore, Value after 19 years=$53
The answer is in the image
F=ma
where F=force
m=mass
a=acceleration
Here,
F=4300
a=3.3m/s2
m=F/a
=4300/3.3
=1303.03kg
Approximately it is aqual to 1300kg
Salesperson will make 6% of 1800
=(6/100)*1800
=108
Salesperson will make $108 in $1800 sales
The solution is given in the image below
Speed=Distance/time
distance=15m
time=1sec
speed=15/1=15m/sec
Distance=Speed*time
time=15min=15*60sec=900sec
Distance travelled in 15 min=15*900=13,500m
=13500/1000 km=13.5Km
It will provide an instant answer!
