Answer:
The greatest number of games Elie could have played was 4.
Step-by-step explanation:
This is because if you take 25 and subract the 5.25, you would get 19.75. In order to get the max games Elie could play, you would divide 19.75 by 4, since each game is $4. You would end up with 4.9, but would have to round down since you can't round up.
Answer:
89·98 mph
Step-by-step explanation:
First, we get the circumference of the tires:
Circumference = 
× (radius × 2)
Circumference = 3.142 × (1·5 × 2)
Circumference = 3·142 × 3
Circumference = 9·426 ft
The circumference of the tire is equal to one round.
1 round = 9·426 ft
840 rounds = ?
We cross multiply to get the length that the tires would cover in a minute
= <u>840 × 9·426</u>
1
1 minute = 7917·84 ft
60 minutes = ?
<u>60 × 7917·84</u>
1
= 475070·4 ft
5280 feet = 1 mile
475070·4 feet = ?
<u>475070·4 × 1</u>
5280
475070·4 ÷ 5280 = speed of the car in mph
89·97545
Round this off to 2 decimal places...
= 89·98 mph
hope this helps! =)
Answer:
2.6768·10^(-14) (Answer C)
Step-by-step explanation:
Problem 4: We ADD the powers of 10: 10^6·10^(-3) = 10^3. Also, 3.6·1.7 = 6.12. Therefore, Answer D is correct.
Problem 5: Again we ADD (combine) the powers of 10: 10^(-10)·10^(-5) =
10^(-15). 4.78·5.6 = 26.768. Our intermediary answer is thus:
26.768·10^(-15). This must be rewritten in the form x.xxxx, so here we have:
2.6768·10^(-14) (Answer C)
