Answer:
What is 20 percent of 500.? = 100.
Step-by-step explanation:
Answer:
D. The scale factor is 1:840
Step-by-step explanation:
Make 630 ft into inches, so 7560
Then make it 9/7560, which simplifies to 1/840
The product is a bit less than the estimate. In fact, 7.69 is less than 8, and if you start with an equality, i.e.

you can multiply both sides by a positive number, and the inequality will still hold:

Answer:
10.27 feet/sec.
Step-by-step explanation:
The distance traveled by the car, d in feet, is given by the function
.......... (1), where t is the time in seconds.
So, at t= 2 sec, from equation (1) we get d = 1.1 × 4 = 4.4 feet.
Again, at t = 5 sec, we get d = 1.1 × 32 = 35.2 feet.
Now, average speed of the car from t = 2 sec. to t = 5 sec. will be give by
=
feet/sec. (Answer)
