Answer:
36 miles.
Step-by-step explanation:
We have been given that Karina rode her bike up a mountain trail at an average of 4 mph. Then she rode it back down the trail at an average of 20 mph. The entire trip took 3 hours.

Substitute the given values:




The total distance is 72 miles, so the distance going up would be half of 72.

Therefore, Karina went 36 miles up the mountain.
Answer:
No. It is an obtuse triangle.
Step-by-step explanation:
If c^2>a^2+b^2, then the triangle is obtuse. Since 24^2 + 7^2 is 625, and the square root of 625 is 25, that means 26>25. This proves that the triangle is obtuse.
Answer:
<h3>x = 12</h3>
Step-by-step explanation:
Given the triangle MNO which is extended through point O to point P, we are given the followings;
Interior angles;
∠MNO=(3x+11)
∠OMN=(2x+20)
Exterior angle;
∠NOP=(8x−5)
To find x, we will use the theorem, "The sum of the interior angles is equal to the exterior"
Hence;
3x+11+2x+20 = 8x - 5
5x + 31 = 8x - 5
Collect like terms;
5x - 8x = -5-31
-3x = -36
x = -36/-3
x = 12
Hence the value of x is 12
Kilo is the prefix for 1,000, hope i was helpful.
greatest to least: 6.32, 6, 4.27, 4, 3.5 .
I got 4.27 by multiplying 4 x 11, adding three which makes it 47 and then divided it by 11
