Answer:
I'm not sure about "11" but 12. is "by the definition of right angles", and 16. is "by the SAS(side angle side) congruency theorem"
Since this is an improper fraction, you simplify it into a mixed number.
4 goes into 6 1 time. 2 left left over, resulting in 1 2/4. Simplify that into
1 1/2
Answer:
x = ±4 (x = 4 and x = -4)
Step-by-step explanation:
4x²-16 = x²+32
3x²-16 = 32
3x² = 48
x² = 16
x = ±4
Therefore, x = 4 and x = -4
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.
