A lot has area :A = 600 sq. yardsIt has a frontage of 40 feet. We have to calculate the length of the lot, if it was a rectangular in shape.Area of a Rectangle = Length x Width600 = L x 40L = 600 : 40L = 15 feetAnswer: The length of the lot measures 15 feet.
Answer:
12 hello how are you doing
Answer:
Step-by-step explanation:
<u>Given</u>:
AC + CB = 33
CB = 2AC
<u>Find</u>:
AC, CB
<u>Solution</u>:
Using substitution, we have ...
AC +2AC = 33
AC = 33/3 = 11
CB = 2·11 = 22
AC = 11 cm; CB = 22 cm.
Answer:
- <u>They can catch up with the bus at 10:40 am.</u>
Explanation:
1. Set the time when Liana and her mother can leave (8:40 am) as t₀ = 0; thus the time of driving for them will be t.
2. The average speed at whic Liana's mother drive: 60 miles/hour
3. Thus, the distance they will have driven will be:
- distance = average speed × time = 60t
4. The time the bus left was 8:00 am, which is 40 minutes before Liana and her mom can leave.
Thus, the time wil have driven when Liana and her mom have driven t hours minutes will be: t + 40 min / 60 min/ hour = t + 2/3
5. The average speed of teh bus is 45 miles / hour
6. The distance the bus will have driven will be:
- distance = average speed × time = 45(t + 2/3)
7. When Liana and her mother catch up with the bus, the distances driven by both of them are equal:
Thus, Liana and her mom can catch up with the bus after 2 hours, since 8:40 am; this is, 10:40 am.
