The independent variable is whatever object you can control and alter and the dependent variable is the variable which reacts to that one. you didn’t include a description for your experiment but for example, when brushing your teeth the independent variable is the toothpaste and the dependent variable is how much foam stuff will appear when brushing. let me know if that makes sense

Step-by-step explanation:

For this you need to divide the 2 fractions, and what ever you get will be the answer.

$4\frac{1}{2}$ ÷ $\frac{3}{4}$

First make the mixed fraction into a improper fraction.

$\frac{9}{2}$ × $\frac{4}{3}$ = $\frac{36}{6} =\frac{5}{1} =5$

What is the slope of the line?<br> hurryyyy

Fittoniya [83]

Answer:

slope = 3

Step-by-step explanation:

if each square is equal to 1

The slope has to be 3.

you can see it, because between those 2 point you can count 3 spaces in y-vertex, and 1 space in x-vertex

what that means is that we will move 3 steps up (or down) for each 1 space in x-vertex.

you can see it just right there on the graph

A company makes paper labels for paint cans. As shown below, cach can is in the shape of a cylinder with a height of 9 cm and a

IgorC [24]

Given:

Height of cylinder, h = 9 cm

Radius, r = 3 cm

Total amount of paper the company has = 8138.88 cm²

Let's find the number of labels that can be made given that the label covers only the side.

Here, we are to apply the formula for the surface area of a cylinder.

We have:

$SA=2\pi rh+2\pi r^2$

The 2πr² represents the area of the top and bottom circle of the cylinder.

Since the label covers only the side, we are to exclude the 2πr².

Hence. we have:

$SA_{label}=2\pi rh$

WHere:

r = 3 cm

h = 9 cm

Thus, we have:

$\begin{gathered} SA_{label}=2*3.14*3*9 \\ \\ SA_{label}=169.56\text{ cm}^2 \end{gathered}$

Now, the number of labels they can make is:

$\begin{gathered} \text{ number of labels = }\frac{8138.88\text{ cm}^2}{169.56\text{ cm}^2} \\ \\ \text{ number of labels = 48} \end{gathered}$

Therefore, the company can make 48 labels.

ANSWER:

48 Labels
