What is the greatest common factor of 12 and 30

Answer:

If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations. the intersection points (-3,3) Since the system is infinite it means there is 1 line on the graph-

Step-by-step explanation:

The solution (infinitely many solutions) in this case means the runners are at the same place at any point in time.

When a set of linear equations has a single solution,

In the case of coinciding lines with the same y-intercept, the number of solutions to the equation system is unlimited. The two lines are actually in the same line if they share the same slope and y-intercept.plied set then has a special solution.

We have two runners racing against each other.

The two equations form a system that has infinitely many solutions.

Thus, the solution (infinitely many solutions) in this case means the runners are at the same place at any point in time.

[tex]\\ \rm\hookrightarrow x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]\\ \rm\hookrightarrow x=\dfrac{-5\pm\sqrt{25+32}}{4}[/tex]

[tex]\\ \rm\hookrightarrow x=\dfrac{-5\pm\sqrt{57}}{4}[/tex]

Let's call one ratio = x

So, the sides are 3x, 5x and 7x respectively.

Since the perimeter is 90 cm, the sum of 3 sides = 90 cm

-> 3x + 5x + 7x = 90 cm

-> 15x = 90cm
-> x = 6cm.

So, the 3 sides are 3x6, 5x6 and 7x6 -> 18,30 and 42.

Recheck : 18 + 30 + 42 = 90

18:30:42 = 3:5:7 (all divided by 6)

Answer:

dependent variable

Step-by-step explanation:

from what i have seen this is the right choice heres an example of how i came up with it you can decide off of this

Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). ... Example: Your test score affects how long you sleep.

Problem 1

x = measure of angle N

2x = measure of angle M, twice as large as N

3(2x) = 6x = measure of angle O, three times as large as M

The three angles add to 180 which is true of any triangle.

M+N+O = 180

x+2x+6x = 180

9x = 180

x = 180/9

x = 20 is the measure of angle N

Use this x value to find that 2x = 2*20 = 40 and 6x = 6*20 = 120 to represent the measures of angles M and O in that order.

====================================================

Problem 2

n = number of sides

S = sum of the interior angles of a polygon with n sides

S = 180(n-2)

2700 = 180(n-2)

n-2 = 2700/180

n-2 = 15

n = 15+2

n = 17

====================================================

Problem 3

x = smaller acute angle

3x = larger acute angle, three times as large

For any right triangle, the two acute angles always add to 90.

x+3x = 90

4x = 90

x = 90/4

x = 22.5

This leads to 3x = 3*22.5 = 67.5

cool... the question?

Step-by-step explanation:

The constant of proportionality of the equation is 29.4

If the amount of money an accountant makes, m, is directly proportional to the time taken, this is expressed as:

m = kh

where;

k is the variation constant

Given that the amount of money an accountant makes, m, for working h hours is represented by the equation m = 29.4h, the variation constant is calculated as:

29.4h = kh

k = 29.4

Hence the constant of proportionality of the equation is 29.4

use pythag theorum you get 11.7 i thinkkk

Step-by-step explanation:

Try creating a triangle using the length of x and the length of y, so, you can tell the line goes from -5 to 5 on the x axis so that means its 10 long on x and 0 to 6 on y axis so its 6 long on y... then create a triangle and use the pythagorean theorem (the square root of (10 squared + 6 squared) which is around 11.7 .... i think, hope that helps! -prowl

Answer:

[tex]\frac{1}{30}[/tex]

Step-by-step explanation:

Separate into Case 1 and Case 2:

Case 1: We want a yellow marble

There is only 1 yellow marble out of the 6 marbles.

Probability for a yellow marble = [tex]\frac{1}{6}[/tex]

Case 2: We want a blue marble

There is only 1 blue marble out of the 5 marbles remaining. (We took 1 yellow marble out already)

Probability for a yellow marble = [tex]\frac{1}{5}[/tex]

Multiply Case 1 with Case 2 because they are a combination:

Answer:

h = 20 km

Step-by-step explanation:

Mario's path forms a right triangle with legs 16 km and 12 km and hypotenuse h. Let's use the Pythagorean Theorem (a² + b² = c²) to solve for h.

16² + 12² = h²

256 + 144 = h²

400 = h²

h = 20 km

Answer:

16

Step-by-step explanation:

We know the midline is

(5.2,7)

And the minimum is (1.2,1.2)

Note that the distance from the midline to minimum or max is 1/4 the distance of the period.

The period is respected to x so only look at the the x values.

So

Step 1: Find the distance from minimum point and midline.

[tex] |5.2 - 1.2| = 4[/tex]

Step 2: Multiply that by 4

[tex]4 \times 4 = 16[/tex]

So the period is 16.
