Mark is in training for a bicycle race. He needs to ride 50 kilometers a week as part of his training. He rode 18.23 kilometers

castortr0y [4]

Mark has to ride 50 kilometers. He already rode 18.23 and 13.94.

18.23km+13.94km=32.17km

50km-32.17km=17.83km

Mark will have to ride 17.83km more. The correct answer is B.

Which does not show a direct variation between x and y?

ziro4ka [17]

The one that does not show a direct variation is that answer B because I notice that letters A, C, and B have slopes and that the function is equal to kx, making it a direct variation. But on the answer B, the function y = 6/x is a indirect variation, making it equal to xy = 6.

Sort data from least to greatest 7 1/2, 7, 4, 2 1/2, 0, 3, 1 1/2, 4, 4

irina1246 [14]

Answer:

0, 1 1/2, 2 1/2, 3, 4, 4, 4, 7, 7 1/2

0, 1.5, 2.5, 3, 4, 4, 4, 7, 7.5

Step-by-step explanation:

7 1/2, 7, 4, 2 1/2, 0, 3, 1 1/2, 4, 4

Let's convert all the numbers to decimals

7 1/2 is 7.5

2 1/2 is 2.5

1 1/2 is 1.5

So here are all the numbers

7.5, 7, 4, 2.5, 0, 3, 1.5, 4, 4

Let's start with the smallest number which is 0 and go to the highest (7.5)

so...

0, 1.5, 2.5, 3, 4, 4, 4, 7, 7.5

Then convert back into fractions if needed.

0, 1 1/2, 2 1/2, 3, 4, 4, 4, 7, 7 1/2

A 25-foot ladder rests against a vertical wall. The foot of the ladder is 10 feet from the wall. What angle does the ladder make

attashe74 [19]

Here's your illustration:

I don't know if you can see that picture, but it's not showing up on my screen, so I'll describe it to you:
-Draw a right triangle
(It's a right triangle because the wall is vertical so the wall creates a right angle with the ground)
-The hypotenuse [the slanted side opposite the right angle] is your ladder. The length of the ladder is 25, so the length of your hypotenuse is 25.
-The long leg of the triangle [the long side that is not the hypotenuse] is your wall. We don't know the length of the wall, but that's okay for this problem.
-The short leg of the triangle [your shortest side] is the distance between the bottom of the ladder and the bottom of the wall. That's 10.

So you have your triangle. The angle the ladder makes with the wall is the angle between the top of the ladder and the top of the wall.
Your answer depends on the equation you're going to use to find this angle.
That depends on what lengths are given to you, which in this case is the hypotenuse and the short leg.
Your angle is opposite the short leg. This means the angle is not the right angle, and not an angle touching the short side.
The sine ratio is opposite side/hypotenuse
You have both the opposite side of the angle and the hypotenuse, so your formula would be this:
sin(angle)=10/25

So your answer would use the sine ratio, meaning your answer is...

sin-10.4

And there's your answer.
