Time taken for Kristin to catch up with the truck will be found using the formula
time=(distance)/(speed)
distance=20 km
speed=90 km/h
thus
time=20/90=2/9 hours
Answer: 2/9 hours
First the question asks you how many problems Cesar did per day in a 5 day school week. We know that he did 100 problems in that 5 day week, so you should divide 100 by 5 to get 20. Now we know that Cesar does 20 problems per day. Now the question want you to find how many problems he would do if this rate keeps up in three 5 day weeks. We know that he does 100 problems in a five day week, so multiply 100 by 3 to get 300. So Cesar does 300 percent problems in three weeks and 20 problems in one day.
Answer:
y = (-5/3)x + 4
Step-by-step explanation:
Line contains (-3, 9) and (3, -1)
slope A = Δy/Δx = (-1 - 9) / (3 - (-3)) = -10 / 6 = -5/3
y = (-5/3)x + B
find the intercept B by plugging in either known point set.
9 = (-5/3)(-3) + B
9 = 5 + B
B = 4
