15%=0.15
4,500x0.15=675
4,500+675=$5,175
31/18 is the answer.
To solve, find the common denominator. In this case, I used 54. You need to multiply each fraction to get 54 on the denominator of both.
Answer:
6,6
There are 8 spaces in bettween point a and b so 8/2 = 4 so 4 up from point a is 6,6
Step-by-step explanation:
Firsly, the speed of Yochanan is not constant. So he has done a motion that contains an acceleration c.
for this type of movment, the equation is X= 1/2ct²+Vit
and with this last, we can find the equation of speed by dX/dt= ct + Vi
so v= ct+Vi
Vi the initial speed
<span>n average speed of 60 km/h until he got to school implies 60=ct+ 5,
</span>t =1.5 hour, so c= 60 - 5 / 1.5 = 56.66
and by using the formula during the motion with the bus)
V²f - V²i = 2. c (xf -xi) so V²f= 3600km/h V²i = 25 km/h
we can find xf -xi= V²f - V²i / 2c, and <span>xf -xi= 31.54 km
</span> but the total distance is 35 km,
so 35km - 31.54km = 3.45 km
yochanan coverd 3.45 kmby walking
yochanan coverd <span>31.54 km </span>km by riding bus
Each sub will feed 3 people if they split it by 1/3
take 12 and divide by 3
12/3= 4
they'll need 4 whole subs to feed 12 people
