How to find a slope
exis [7]

Answer:

Step-by-step explanation:

y₂₋y₁ / x₂-x₁   if you have two points you can plug them in and find the slope using this.

If it is on a graph you can look at two points and count the rise over run, for example if one point is (0, 0) and another is (2, 3) then from the first point it goes up 2 and over 3, so the slope would be 2/3

The number of boys varies directly as the number of girls and inversely as the number of teachers. When there are 24 boys and 16
lidiya [134]
SO from what I did was...

Since 24 x 3 = 72 , I did the same to 16. 

16 x 3 = 48 

But because instead of their being 3 teachers there is 1... What I did is just was to divide 48 / 2 which gave me the answer of 24... 

So what I think the answer is... 

There are 72 boys, 24 girls, and 1 teacher... 

Unless I am just dumb and it would be 48 girls, but I think I did it right. 

I hope I was able to help out.

Find the simple interest owed for the use of the money. Assume 360 days in a year. P=16,500, r=6%, t=180 days
Taya2010 [7]

The formula for simple interest is the following:

S=Prt

In this formula, S is the amount of interest, P is the principal (or initial) amount, r is the interest rate, and t is the length f time, typically in years.

First, let's make a couple of changes to how we wrote down the variables.

  • Change the interest rate, 6\%, to the decimal value 0.06.
  • Convert the length of time to years. 180 days divided by 360 days per year equals 0.5 years.

Substitute in the values and solve with a calculator.

\begin{aligned}S&=16,500\cdot0.06\cdot0.5\\&=\boxed{495}\end{aligned}
