You can simply divide 2 by 5 and you will get 0.4
Answer: 21
Step-by-step explanation: f(-2) = 4· (-2)²-(-2) + 3 = 4·4 +2 +3
17 and 1
There is no other multiples because 17 is a prime number and prime number can only be multiplied by 1 and itself.
Answer:
4.) 40 Apps can be downloaded in 1 minute
5.) 0.2 or 2/10 of a miles can be traveled in 1 second
Step-by-step explanation:
4.)
So 12 seconds is = to 1/5 of a minute
So the question asks for 1 minute
This means that we need to perform 1/5 *5 to get 1 minute
If we multiply 5 to 1/5 minutes, we also need to multiply 5 to the apps
8 * 5 = 40
So that is how we solved the answer.
So DeAndre can download 40 Apps in 1 minute.
5.)
So he traveled 1/10 miles in 1/2 or 0.5 seconds.
This means we can multiply the seconds by 2 to get 1 second.
0.5 * 2 = 1
If we multiply the seconds by 2 we also need to multiply the miles traveled by 2.
So (1/10) * 2
The 2 can be rewritten as (2/1) because 2/1 is the same as 2
(2/1) * (1/10)
So we multiply straight out and get 2/10 miles traveled which can be simplified to 1/5 miles traveled.
