Mathematics
1 answer:
marishachu [46]3 years ago
8 0

Answer:

\frac{\sqrt{3} }{4} a^2

Step-by-step explanation:

To find the area of an equilateral triangle, we can apply a formula.

A=\frac{\sqrt{3} }{4} s^2

A= area\\s=side \: length

The side length is given a.

Plug a in the formula as the side length.

A=\frac{\sqrt{3} }{4} a^2

4 < 4(6y - 12) - 2y       |use distributive property

4 < (4)(6y) + (4)(-12) - 2y

4 < 24y - 48 - 2y       |add 48 to both sides

52 < 26y      |divide both sides by 26

2 < y → y > 2

---------------------------------------------------------

4x + 3 < 3x + 6      |subtract 3 from both sides

4x < 3x + 3       |subtract 3x from both sides

x < 3

------------------------------------------------------------

-5r + 6 ≤ -5(r + 2)        |use distributive property

-5r + 6 ≤ (-5)(r) + (-5)(2)

-5r + 6 ≤ -5r - 10         |add 5r to both sides

6 ≤ -10     FALSE

No solution

-------------------------------------------------------------

-2(6 + s) ≥ -15 - 2s        |use distributive property

(-2)(6) + (-2)(s) ≥ -15 - 2s

-12 - 2s ≥ -15 - 2s        |add 2s to both sides

-12 ≥ -15     TRUE

All real numbers

-------------------------------------------------------------

3s + 6 ≤ -5(s + 2)        |use distributive property

3s + 6 ≤ (-5)(s) + (-5)(2)

3s + 6 ≤ -5s - 10         |subtract 6 from both sides

3s ≤ -5s - 16        |add 5s to both sides

8s ≤ -16         |divide both sides by 8

s ≤ -2

--------------------------------------------------------------

Basile [38]

Answer:

Gender is a categorical variable. The sum gives the total number of students in class.

Step-by-step explanation:

We are given the following in the question:

The variable​ Male, is​ categorical, even though its values are numbers.​

Categorical variable:

  • These variable are the non parametric variable.
  • They do not need values to express the data.
  • They only use number and numerical to express the data or represent the data.
  • There is no relation with true value of numerical.

Thus, gender is a categorical variable. Numbers are only used to represent the data.

Numbers are just a representation.

The sum of these represent the total male and female students in class. Thus, the sum gives the total number of students in class.

WILL MARK BRAINLIEST <br> in detail, what would you do in order to graph y = 3x -5
Hunter-Best [27]

So first, you need to identify the parts of this equation.

3x is the slope of the line, which is \frac{3}{1}.

-5 is the y-intercept. or the part of the line that touches the y-axis.

The first thing you want to do is plot the y-intercept. SO, go to the y-axis and find -5. Plot your point there.

Now, use the slope \frac{3}{1} to find your next plot. Since slope is \frac{rise}{run}, you go up three, and over to the right one.

Now, draw a line connecting the dots. Your slope should be positive and look like > /
