Hm ok, so the answer here would be 9/40

Kinda big right? Heres my reasoning:

To find the answer when the denominators and different, you cross multiply using each of the bottom numbers like this:

$\frac{5}{5} \frac{*}{*} \frac{5}{8}=\frac{25}{40} \\\\\frac{8}{8} \frac{*}{*} \frac{2}{5} =\frac{16}{40}$

Then we subtract 16 from 25 to get 9.

I would like to simplify, but 40 and 9 don't have any common denominators unfortunately.

What is the value of y for the line that has a slope of 1 and goes through the points (-4, y) and (-2, 8)?

Pavel [41]

Answer:

y = 6

Step-by-step explanation:

To write the equation of a line, calculate the slope between points (-4,y) and (-2,8). Substitute m = 1 and solve for y.

$m = \frac{y_2-y_1}{x_2-x_1}\\\\ 1 = \frac{y-8}{-4--2}\\\\ 1 =\frac{y-8}{-2}\\\\-2=y-8\\\\6=y$

Suppose the half-life of a material is 10 days. You have one 1 kg of the material today. How much of the material would you have

boyakko [2]

Answer:

0.50 kg of the material would be left after 10 days.

0.25 kg of the material would be left after 20 days.

Step-by-step explanation:

We have been given that the half-life of a material is 10 days. You have one 1 kg of the material today. We are asked to find the amount of material left after 10 days and 20 days, respectively.

We will use half life formula.

$A=a\cdot(\frac{1}{2})^{\frac{t}{h}}$ , where,
