Step-by-step explanation:

An equilateral triangle is a triangle with three equal sides. The perimeter of an equilateral triangle varies directly with the length of one side. What is an equation that relates the perimeter p and length of a side?

See, let us consider the sides as l as per question.

And, perimeter as p as per question.

We know that:-

The sum of all the boundary gives us the perimeter of the figure.

It is Equilateral Triangle, so the equation will be:-

[tex]l + l + l = p[/tex]

Now, adding it up, we get

[tex]3l = p[/tex]

So, 3l=p relates the side and perimeter.

Hope it helps :)

Answer:

180

Step-by-step explanation:

subtract 45,000 (the money you already get) from 90,000 and you get 45,000. next divide 45,000 by 250 and get 180 (the amount of units you need to sell in order to make 90k total)

Answer:

x=1/3

Step-by-step explanation:

(18x+3)^2=81

square root both sides

18x+3=9

subtract 3 from both sides

18x=6

divide 18 on both sides

x=1/3

Answer:

25

Step-by-step explanation:

It's what the others said, i'll change it if it's wrong

Based on the description of cost and the equation used, m in the equation would represent $25

m in the equation, y = mx + b, is the gradient. It is the figure that shows how much the cost will change in relation to time or activity.

In other words, m is the variable cost.

The only variable cost above is $25 which is variable because it increases per hour worked. m is there $25.

In conclusion, m is $25.

Answer:

Complementary Angles

Step-by-step explanation:

Complementary angles are angles whos measures add up to 90 degrees! The angles in the picture can also be described as adjacent angles, because they share the same vertex.

So these angles are technically both complementary and adjacent, but they are more specifically, complementary.

I hope I was of assistance! #SpreadTheLove <3

Answer:

5,4.09,4,-2.52,-3,-543

Look : angle 1 + angle 3 = 180°

because it is a straight line.

Thus ;

[tex]5x + 35 + 4x + 10 = 180[/tex]

Simplification

[tex]9x + 45 = 180[/tex]

Subtract sides 45

[tex]9 x = 180 - 45[/tex]

[tex]9x = 135[/tex]

Divided sides 9

[tex] \frac{9}{9}x = \frac{135}{9} \\ [/tex]

[tex]x = 15[/tex]

So x = 15°

_________________________________

angle 1 = 5x + 35°

angle 1 = 5 ( 15 ) + 35°

angle 1 = 75° + 35°

angle 1 = 110°

_________________________________

angle 1 + angle 2 = 180°

110° + angle 2 = 180°

Subtract sides 110°

angle 2 = 180° - 110°

angle 2 = 70°

Answer:

[tex]\boxed {r = \frac{31}{3}}[/tex]

Step-by-step explanation:

To find the value of [tex]r[/tex], write an expression by using the following measurements of both [tex]\overline {DG}[/tex] and [tex]\overline {GM}[/tex], then you solve for [tex]r[/tex]:

[tex]\overline {DG} = r + 3[/tex]

[tex]\overline {GM} = 4r - 28[/tex]

[tex]r + 3 = 4r - 28[/tex]

Solve for [tex]r[/tex]:

[tex]r + 3 = 4r - 28[/tex]

[tex]x + 3 - 4r = 4r - 4r - 28[/tex]

[tex]-3r + 3 = -28[/tex]

[tex]-3r + 3 - 3 = -28 - 3[/tex]

[tex]-3r = -31[/tex]

[tex]\frac{-3r}{-3} = \frac{-31}{-3}[/tex]

[tex]\boxed {r = \frac{31}{3}}[/tex]

So, the value of [tex]r[/tex] is [tex]\frac{31}{3}[/tex].

Answer:

(a) The total combined paint is 10.3L

(b) 8.8L paint was left after painting

Step-by-step explanation:

From the question, John combines 7L of white paint with 3300 milliliters of blue paint.

First, convert to the same unit, say liters, L.

Now, we will convert 3300 milliliters to liters (L)

{NOTE: 1000 milliliters (mL) = 1 liter (L)}

Since 1000 milliliters = 1 liter

∴ 3300 milliliters = 3300/1000 liters = 3.3 liters

Hence, 3300 milliliters = 3.3 L

Therefore, he combines 7L of white paint with 3.3L of blue paint.

(a) The total combined paint is 7L + 3.3L = 10.3L

∴ The total combined paint is 10.3L

(b) To determine how much paint was left after painting,

From the question, he uses 1 ½ L of paint to paint a hallway, that is, he uses 1.5 L of paint to paint a hallway;

The paint left will be 10.3L - 1.5L

10.3L - 1.5L = 8.8L

Hence, 8.8L paint was left after painting

Step-by-step explanation:

y-y1=m(x-x1)

y-7=4(x+8)

y-7=4x+32

4x-y=-39

Answer:

y = 4x + 39

Step-by-step explanation:

Let's take another point (x,y) on the line.

Slope (m) = change in y ÷ change in x

∴ m = [tex]\frac{y - 7}{x - -8} = 4[/tex]

y = 4x + 32 + 7

y = 4x + 39

3(x+4)

3*x=3.....keep the x with 3 because x just represents 1

3*4=12

so your answer should be

3x+12

Answer:

36

Step-by-step explanation:

We have the summation:

[tex]\displaystyle{\sum_{i=1}^{9} 2i-6[/tex]

Essentially, we want to find the sum of (2i-6) from i=1 to i=9.

First, using summation properties, we can split this to:

[tex]=\displaystyle{\sum_{i=1}^{9} 2i+\displaystyle{\sum_{i=1}^{9} -6[/tex]

On the right, it will simply be -6 evaluated 9 times. We can also move the constant out from the left:

[tex]=\displaystyle{2\sum_{i=1}^{9} i+9(-6)[/tex]

For the summation on the left, this will simply be the sum (1+2+3+...+9). This yields 45. Therefore:

[tex]=2(45)+9(-6)[/tex]

Evaluate:

[tex]=90-54=36[/tex]

So, our final answer is 36.

Answer:

1/2 is the slope of a line with equation y.

Answer:

Domain: [-2, 0, 2, 4]

Range: [3]

Step-by-step explanation:

The domain of the function are all values of x that are plotted on the horizontal axis (x-axis), while the range are the corresponding y-values plotted on the vertical axis (y-axis).

Therefore,

Domain of the function = [-2, 0, 2, 4]

Range of the function = [3] (only 1 possible value of y can be seen as plotted on the gray]

Answer:

Step-by-step explanation:

you can use desmos for a quick answer or

use y=mx+b where b is the y-intercept and m is the slope

the y-intercept is where the line intercepts the y axis

the slope is the rate of change of the line

for slope we use rise/run, the numerator being up and denominator being to the right.

the slope is 3, which can be written as 3/1

from the point (0,-4) which is out y-intercept, we go up 3 and to the right 1
