After running for 18 minutes, Julissa completes 2 kilometers. If she is running a 10-kilometer race at a constant pace, then she comletes 1 kilometer after running 9 minutes. Now you can find the distance she run after 1 minute. This is 
km.
Let t be the time in minutes. Then k, the number of kilometers, can be found from proportion:
- 1 minute
k km - t minutes.
Thus,
Answer: 
Answer:
Equilateral and acute
Step-by-step explanation:
Notice that the angles of the triangle are all 60 degrees which is less than 90 degrees. Also notice the lines in the middle of the triangle lines, those signify that the lines are the same length. Thus making it acute and equilateral
Answer:
and 
are two such planes.
Step-by-step explanation:
To find the two planes whose intersection is the line
You can say that <em>t</em> is equal to this expression
Next,
Then,
and are two such planes.
You can see in the image attached that the intersection of this planes is the line
I think it’s 5 because I think it’s 6
Answer:
105
Step-by-step explanation:
Using basic algebra and the fact that the sum of all angles in a triangle always equals 180, we find that X = 21
Multiply 21 by three to find the value of 3x, which is 63
Add 12 to 63: 75
We also know that the angle of a straight line is also 180, so we subtract 75 from 180 to find ? which is 105
Hope this helps :)
