Answer:
- 4 nickels
- 60 mph
Step-by-step explanation:
1. If all were dimes, the value would be $8.00. The value is actually $0.20 less than that. Replacing a dime by a nickel decreases the value by $0.05, so there must be $0.20/$0.05 = 4 nickels.
2. The total of the two speeds is the rate of closure: (420 mi)/(4 h) = 105 mi/h. The speed of the second car is found by subtracting the speed of the first car from this total:
105 mph - 45 mph = 60 mph
Answer: -4 yards
Step-by-step explanation:
The Warriors lost 11 yards in one play.
They then gained 7 yards in the next.
The total yards gained is therefore a sum of the yards lost and gained:
= -Yards lost + Yards gained
= - 11 + 7
= -4 yards
First we need to find out what her increase is so 50% of 1000 is is 500 so from 12am to 1am she made
1500
from 830 to 12 am gives us 4 1/2 hours so she got paid 4500 for those hours adding on the past 12am and we get
6000 as the total amount she made
