<u>Answer:</u>
Approximately after 2 hours the distance between the two cars will be 268 miles.
Solution:
We know .
Here it is given that the speed of Car 1 is 65 mph and the speed of car 2 is 2.5 mph faster than car 1. It means that the speed of car 2 is (65+2.5) = 67.5 mph
We will use the below given equation to find out the time after which the distance between the two cars will be 268 miles.
Let ‘t’ be the time after which the distance between the two car will be 268 miles.
∴ A/Q,
Therefore, approximately after 2 hour the distance between the two cars will be 268 miles.

7
or -7
Step-by-step explanation:
sqrt(49)
What number multiplied by itself = 49
7*7 = 49
-7*-7 = 49
Answer:
m = -2
Step-by-step explanation:
Slope Formula:
Simply plug in your coordinates:
m = (-2 - 2)/(6 - 4)
m = -4/2
m = -2

Answer:
Step-by-step explanation:
- <em>During a mathematics activity, teacher Julieta distributed to each of her students 4 straws measuring 2 cm, 3 cm, 7 cm and 8 cm. In this activity, Julieta's students had to build triangles with these straws, without cutting them.
</em>
- <em>How many different triangles could each of Julieta's students form with these straws?</em>
==========================================================
- <em>Triangle inequality theorem says that no any side of a triangle can be longer or equal to the sum the other two sides</em>
<u>Given measures:</u>
<u>We see that:</u>
Therefore we can't make triangles with the sides of 2 cm, 3 cm and 7 cm or 8 cm
<u>Possible solutions are:</u>
- 2 cm, 7 cm, 8 cm
- 3 cm, 7 cm, 8 cm
So we can make two different triangles
