Answer:
120 minutes
Step-by-step explanation:
large horse + small horse = together
1 pool/40 minutes + x = 1pool/30 minutes
1/40 + x = 1/30
subtract 1/40 from both sides
x = 1/30 - 1/40
use 120 as common denominator
x = 4/120 - 3/120
x = 1/120
x = 1 pool / 120 minutes
It takes the small horse 120 minutes
Answer:
6 round trip visits
Step-by-step explanation:
25 min drive to the store + 3 min to walk in the store + 3 min to walk back to car + 25 min to drive home = 56 total minutes for one round trip.
5 hours and 36 minutes = (5x60)+36 minutes=336 minutes
336 minutes/56 min per trip = 6 round trips
To the left of the vertical bar are the tens places. As we want to find the scores greater than 90, we start at the row in the stem and leaf plot with a 9 to the left. To the right are 6 values - 1, 2, 3, 4, 6, and 7. So there are six scores here higher than 90: 91, 92, 93, 94, 96, and 97. Now we move lower to 10 in the tens place. There is one score there - 100. (That smart kid.)
Total up the six scores in the 9 row and the 1 in the 10 row to get 7 scores higher than 90 in this stem and leaf plot.
Thus, there are 7 scores - choice B - in the plot higher than 90.
