Two types of sandwiches were made for a tea party. 55% of the sandwiches were cheese sandwiches and the rest were chicken sandwi

Helen [10]

"To solve this problem, the formula can be used

I = P / T

Where I is the fraction of the sample

P is the amount of the sample

T is the total amount of sample

Since P = 252 chicken sandwiches and I = 0.55

And solve for T

T = 252 / 0.52

T = 458 sandwiches in total"

Answer:

$h=\frac{V}{\pi r^2}$

Step-by-step explanation:

To write this equation with h isolated, we cancel everything else on the right hand side of the equals sign. This means we cancel π and r².

Since both of these are attached to h by multiplication, we divide by both to cancel. We can divide by both at the same time:

$\frac{V}{\pi r^2}=\frac{\pi r^2h}{\pi r^2}\\\\\frac{V}{\pi r^2}=h$

The set of numbers 1, 7, 11 and 36 contains values for m. What value of m makes the equation below true?

Arada [10]

Answer:

Step-by-step explanation:

If m was 1, then it would be

4 +8 = 36, which is not true.

If m was 7, then it would be

28 + 8 = 36, which is true.

If m was 11, then it would be

44 + 8 = 36, which is not true.

If m was 36, then it would be

144 + 8 = 36, which is not true.

Hope that helps!

so,

(10,30) is an exact meet

so is (50,60)

so what is the rise/run

answer

30/40

3/4

so mx+b=

3/4x+22

full equation is 3/4x+22
