A her of 40 horses has 9 white and some black horses. What is the ratio of white to black horses?​
solmaris [256]

Answer:

The number of white horse to white horse is 9 : 31

Step-by-step explanation:

Given as :

The Total number of horses = 40

The number of white horses = 9

Let the number of black horses = x

So, x + 9 = 40

Or x = 40 - 9 = 31

∴ The number of black horses = 31

Now,  The ratio of while to black horses = number of white horse : number of black horse

Or, number of white horse : number of black horse = 9 : 31

Hence The number of white horse to white horse is 9 : 31   Answer

Please help i have to write and i dont understand
Lostsunrise [7]

Answer:

A. This is a vertical angle set. As you can see, they are cut by the transversal and have the exact same interior angle, so it is a vertical angle.

B. Since these too are vertical angles, all you have to do is just put each expression on the sides of an equation like so:

5y-29=3y+19

Once you do this, you just need to simplify the equation by putting like terms together, and then you will find the solution for y, which is 24.

C. We know that the solution for y is 24, so we need to plug it into the equation to find, the angle, so if we do 3*24-19, we get 53, so we need to subtract that from 180 degrees, which is the total angle of the straight line, then we can get 127 degrees, which is what angles <7 and <8 are.
