Answer:
babysitting
Step-by-step explanation:
To find per hour just divide made/hours
49.5/6= $8.25 per hour for gardening
38.6/4= $9.65 per hour for babysitting
8.25<9.65
she earned more babysitting
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
Answer:
what si the question
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let x represent the number of hours that he works. babysitting his neighbors children.
Let y represent the number of hours that he works at the other job.
He earns $10 per hour babysitting his neighbors children. This means that the amount that he earns, babysitting his neighbors children for x hours would be
10x
He earns $12 per hour working at the other job. This means that the amount that he earns, working at the other job for y hours would be
12y
Therefore, the inequality that represent the number of hours that he needs to work at both jobs to earn a minimum of $120 is
10x + 12y ≥ 120
257 is a whole number, interger, and a rational number.
