3. Julie uses 4 green beads and 6 blue beads in each bracelet she makes. What is the total number of green beads Julie will use

Alisiya [41]

The answer is 16

exsplain:
24 divided by 6= 4
4x4=16
For every 6 blue beads Julie used she used 4 green and she made 4 brackets so times 4x4 getting you to 16! Hope this helps

What is the parallel line for (0,4) and y=3/2x+3

pochemuha

The parallel line to y = $\frac{3}{2}$ x + 3 and passes through

the point (0 , 4) is y = $\frac{3}{2}$ x + 4

Step-by-step explanation:

Parallel lines have:

1. The same slopes

2. The different y-intercept

The slope-intercept form of the linear equation is y = m x + c, where

m is the slope of the line and c is the y-intercept

We need to find the equation of the line that is parallel to

y = $\frac{3}{2}$ x + 3 and passes through the point (0 , 4)

∵ The two lines are parallel

∴ Their slopes are equal

∵ The equation of the given line is y = $\frac{3}{2}$ x + 3

∵ The form of the equation is y = m x + c

∴ m = $\frac{3}{2}$

∴ The slope of the line is $\frac{3}{2}$

∵ The equation of the line is y = mx + c

∵ m = $\frac{3}{2}$

∴ The equation of the line is y = $\frac{3}{2}$ x + c

- To find c substitute x and y in the equation by the coordinates of

a point lies on the line

∵ The line passes through the point (0 , 4)

∴ x = 0 , y = 4

∴ 4 = $\frac{3}{2}$ (0) + c

∴ c = 4

∴ The equation of the line is y = $\frac{3}{2}$ x + 4

The parallel line to y = $\frac{3}{2}$ x + 3 and passes through

the point (0 , 4) is y = $\frac{3}{2}$ x + 4

Suppose △ABC has exterior angle at vertex B. The exterior angle is (12x−24)°, m∠A=(3x−6)°, and m∠C=(6x+12)°. What is the measure

Temka [501]

Answer: 96°

Step-by-step explanation:

If a triangle is being drawn, Angle A and C will be the two remote interior angles in the triangle. The sum of the two interior angles has to equal to the exterior angle.

Set them equal each other and solve for x.

(3x-6) + (6x +12) = 12x - 24 Combine like terms

9x + 6 = 12x - 24 Subtract 6 from both sides

- 6 -6

9x = 12x - 30 Subtract 12x from both sides

-12x -12x

-3x = -30 Divide both sides by -3

x = 10

Now since x is 10 degrees we will need to input the value into in for x in the exterior angle expression and break it down.

Exterior : 12(10) - 24

120 - 24 = 96

This means the measure of the exterior angle at vertex B is 96 degrees.

Show that in any group of people, two of them have the same number of friends in the group. (Some important assumptions here: no

julsineya [31]

Answer:

Step-by-step explanation:

Let us assume there are n people in the group. If possible let each have different number of friends.

Number of friends can vary from 0 to n-1 only since no one is a friend of him- or herself, and friendship is symmetrical—if x is a friend of y then y is a friend of x.)

Now n people have friends as 0,1,2...n-1 such that each has distinct number of friends.

But say if A has 0 friends, it means A has no friend,

but there is one B who has n-1 friends i.e. all the others in the party are friends to him including A

This is a contradiction. So it follows in any group of people, two of them have the same number of friends in the group.
