Let the speed of one rider = x

The speed of the second rider would e 2x ( twice as fast)

The total speed of the two riders would be x + 2x = 3x

Speed = Distance / time

Using the numbers:

3x = 72/3

Simplify:

3x = 24

Divide both sides by 3:

x = 8

The speed of one rider is 8 miles per hour

The speed of the second rider is 2(8) = 16 miles per hour.

Answer:

ASA

Step-by-step explanation:

We can see that the triangle has at least one similar side and one similar angle. We can also see that the triangles meet at a point, so they must have the same angle at that point where they connect. So that leads us to our answer being ASA since they have two similar angles and one similar side. This is the answer that I think is correct just by looking at the image. I haven't take this class since last year, so this is simply from memory. Correct me if I am wrong!

This Question is about Animals. I am no vegan, but why is it ok to eat certain animals such as fish and rabbit but not ok to eat
Zigmanuir [339]

Answer:

    From what I looked up on Google vegans don't eat fish, maybe some do but vegetarians do still eat fish. The reason why is because their are many types of health benefits that come with eating fish. "Seafood is a healthy source of protein, is full of heart healthy fats and contains iron and a host of vitamins like B-12" (Honeyager).

  I also feel like they ignore the fact that there food was a real animal cause some of society does not want to look at the thing there eating as a once alive animal cause I feel like they know how badly some animals are taken care of through there life time then kill through half of it. And yes I know that other livestock are taken well care of and given a good life before there death.  And most feel it's not okay to eat dogs is because most people actually live around them and know how sweet and kind they are and how they are pets for most. I also feel if it were cows (or some farm animal) instead, like people kept them as pets(just an example) then they would see the personality of a cow and I  guess they would feel more pity for them and not kill them. I hope you understand it's hard to explain my thinking pattern. IDK but this whole question and answer is just  based on peoples emotions whether they are saddened by it, say they don't care, or others who want to make a difference it's all built around peoples emotions and everyone's different and they have different emotions

The first paragraph I researched and the second is not fact at all, it just the true on how I feel. (It probably made no sense to you) Sorry for the 2 page essay!

The difference between the solutions to the equation x2 =a is 30 what is a ?
Mademuasel [1]
Given equation is x^2 = a

In general solution of x^2 = b is x = + \sqrt{b} and x = -  \sqrt{b}

So the solution of given equation is x = + \sqrt{a} and x = -  \sqrt{a}

Now difference between them is 30.
So we can write
\sqrt{a} - (- \sqrt{a}) = 30
\sqrt{a} +  \sqrt{a} = 30
2 \sqrt{a} = 30
\sqrt{a} = 15

On squaring both side
( \sqrt{a})^2 = (15)^2
a = 225

leva [86]

Answer:

6/7

Step-by-step explanation:

Product of slope of perpendicular line = -1

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\

          = \frac{7-0}{3-9}\\\\=\frac{7}{-6}\\\\=\frac{-7}{6}

Slope of the  perpendicular line = -1/m = -1 ÷ \frac{-7}{6}

                                                     = -1 * \frac{-6}{7} = \frac{6}{7}
