Answer:
145.8 pounds
Step-by-step explanation:
So, if there is 9720 pounds total, and 98.5% of it must be pure paper, than 1 - .985 is how much can be impurities.
1-.985 = .015 or 1.5%
Now lets multiply .015 times 9720
.015(9720) = 145.8
The maximum weight of impurities is 145.8 pounds
Answer:
You should graph the lines (0, 0) to (2, 120), (2, 120) to (2.5, 120), and (2.5, 120) to (3.5, 150).
Step-by-step explanation:
If we see, for the first part, she drive 60 miles an hour and drives for 2 hours. This means that after 2 hours, she has driven 60 * 2 = 120 miles in 2 hours. Then she spends 30 minutes, or half an hour, no moving forward as she changes the tire. Finally, she drives at 30 miles an hour for an hour. This means she has driven 120 + 30 = 150 miles in total after 3 and a half hours.
Our first line goes from (0, 0) to (2, 120), as thats how far we drove in 2 hours. The next line goes from (2, 120) to (2.5, 120), as she was changing a tire and made no progress. Finally, the last line goes from (2.5, 120) to (3.5, 150), as she drives for another hour at 30 miles an hour.
You could make an equivalent fraction by multiplying both numbers by 2.
Lines on a railroad track are parallel lines.
Parallel lines are two or more lines that are in the same plane (flat space) and are always equal distances apart from each other at all points on the line.
Answer:To solve this problem you would have to write 276.5 over 7.9 and divide the numerator and denominator by 7.9 since you want miles per gallon (it should have a denominator of 1 after you divide). When you do this you will get 35, so the Henry family got 35 miles per gallon of gas on the trip.
