In the question we are given three lines L,M and N such that:
Line L is perpendicular to M
and line L is parallel to line N
so the option is (C) M is perpendicular N
Step-by-step explanation
We are given three lines L,M and N such that:
- Line L is perpendicular to M
- Line L is parallel to line N
<u>We know that when one line parallel to the second line and is perpendicular to the third line then the second line is also perpendicular to the third line.</u>
<u></u>
So,the answer is (C) M is perpendicular N
Answer: OPTION B
Step-by-step explanation:
To solve this problem you must add the areas of each rectangle that form the prism;
The area of a rectangle can be calculated with the formula:
There are three pairs of equal rectangles, then you can find the surface area of 3 rectangles and multiply each one by 2, then you obtain that the surface area of the prism is:
For 6, you could divide 56 kilometers by 8 kilometers to get 7 kilometers. Multiply 7 by 5 to get 35. There would be 35 miles in 56 kilometers
<em>2.7 / 3 = 0.9.</em>
Is <em>0.9</em> greater than, or less than <em>1? </em>=)

Answer: 79 full rotations</h3>
====================================================
Explanation:
150 cm = 150/100 = 1.5 m
The wheel has a diameter of 1.5 meters
The circumference of the wheel is
C = pi*d
C = pi*1.5
C = 1.5pi
C = 4.71238898038469
I'm using my calculator's stored version of pi to get the most accuracy.
Then we divide the 376.8 over the circumference found
(376.8)/(4.71238898038469) = 79.9594434093682
Despite being very close to 80, we must round down to 79 because we don't have enough to get that full 80th rotation. In other words, we have 79 full rotations and then some change leftover.
Though for the sake of simplicity, I can see how it's useful to say "about 80 rotations" if 79 seems a bit clunky. I'll stick with 79 however. Let me know if your teacher instructs otherwise.
