It would be C. A perpendicular slope means it has the opposite reciprocal slope, so 1/2 would turn into -2. Since there's only one option with -2 as a slope, C must be right.

The sum of gains is
... (14 yd) + (-32 yd) + (3 yd) + (-19 yd)
... = (14 +3 -19 -32) yd . . . . . . it is often convenient to rearrange the numbers to facilitate mental arithmetic
... = (-2 -32) yd
... = -34 yd
The net change of position was -34 yards.
A. 10 feet.
Think of it like this:
The wall is upright, it's 90° and it's 8 feet high. The distance from the bottom of the ladder to the bottom of the wall (along the ground, which is perpendicular to the wall) is 6 feet. When Benton places the base of the ladder 6 feet away from the wall and the top is resting at the top of the wall, it looks like a triangle, right?
Using pythagoras (this rule about right-angled triangles and stuff), we can already see that the two sides when simplified are 3:4. Because the 'triangle' is a right-angled triangle, the other side HAS to be 5 to complete the ratio. We just multiply it by 2 to get the correct ratio and that's your answer!
Answer:
Step-by-step explanation:
You have to divide 5 by 2 to find the unit rate.
5/2= 2.5
Hope this helps.
That’s easy just place 2.4 on top of 1.5 and do the math, I did it in the picture for you, since there are two decimal points one in 2.4 and the second in 1.5. So the answer is 3.60 as shown in the pic. Any questions ? Sorry the picture is sort of messed
