Complete question :

Miranda is braiding her hair then she will attach beads to the braids she wants 1/3 of the beads to be red if the greatest number of beads that will fit on the braid is 12 what other fraction could represent the part of the beads that are red?

Answer:

2 / 6

Step-by-step explanation:

Fraction of red beads on braid = 1/3

greatest number of braids = 12

Fraction of red beads = (1 /3) * 12 = 4 red beads

Thus implies that :

When greatest number of braids = 12

fraction of red beads) = (Number of red beads / greatest number of beads)

Fraction = 4 / 12

Divide by 2 = 2/6 (don't reduce to lowest term).

First you want to get n on the side by itself.

So 9n-24=4n+6 you want to add 24 to both sides so you get 9n=4n+30 than you want to subtract 4n from both sides to get 5n=30 than divide 5 from both sides to get n by itself and you will get n=6

Answer:

Step-by-step explanation:

The expression for the total distance covered.

k + (k + 8) + (k - 2)

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Distance biked:

Jackson = k

Maria = k + 8

Peter = k - 2

Now,

The total distance biked.

= k + k + 8 + k - 2

= 3k + 6

= 3 (k + 2)

Thus,

The total distance covered is 3 (k + 2).

Answer:

the slope intercept-form of an equation of a line is y=mx+b

Given that the slope is 3 and a point on the line is P(-2, 4), then

m=3 and from the point (-2, 4), x=-2 and y=4.

Step-by-step explanation:

y=mx+b.

4=3(-2)+b   Now solve for b.

4=-6+b

4+6=b

10=b

Now you know b=10 and you already know the slope m=3. Substitute these values into y=mx+b. When you do you will get y=3x+10. This is your answer in slope intercept form.

Answer:

Solving the expression and round to the nearest hundredth

[tex]0(5x+2)=2(9x-6)[/tex] we get [tex]\mathbf{x=0.67}[/tex]

Step-by-step explanation:

We need to solve the expression and round to the nearest hundredth

[tex]0(5x+2)=2(9x-6)[/tex]

Solving:

[tex]0(5x+2)=2(9x-6)[/tex]

We know that multiplying anything by zero we get zero

[tex]0=2(9x-6)[/tex]

Switching sides

[tex]2(9x-6)=0[/tex]

Multiplying 2 with terms inside the bracket

[tex]18x-12=0[/tex]

Adding 12 on both sides

[tex]18x-12+12=0+12\\18x=12[/tex]

Divide both sides by 18

[tex]\frac{18x}{18}=\frac{12}{18}\\x=0.666[/tex]

Rounding to nearest hundredth we get:

[tex]x=0.67[/tex]

So, solving the expression and round to the nearest hundredth

[tex]0(5x+2)=2(9x-6)[/tex] we get [tex]\mathbf{x=0.67}[/tex]

Answer:

-√5/5

Step-by-step explanation:

Given the following

sin(A) = 4/5

sinB - -2√5/5

SinA = 4/5 = opp/hyp

We can get cosA

opposite = 4

hypotenuse = 5

Adj = √5²-4² (pythagoras theorem)

Adj = √25-16

Adj = √9

Adj = 3

Cos A = Adj/hyp

Cos A = 3/5

Also

Sin B = -2√5/5 = opp/hyp

opposite = -2√5

hypotenuse = 5

Adj = √5²-(2√5)² (pythagoras theorem)

Adj = √25-20

Adj = √5

Cos B = Adj/hyp

Cos B =  √5/5

Evaluate cos (A-B)

cos (A-B) = cosAcosB + sinAsinB

cos (A-B) = 3/5(√5/5)+4/5(-2√5/5)

cos (A-B)  = 3√5/25 - 8√5/25

cos (A-B) = -5√5/25

cos (A-B) = -√5/5

Hence the value of cos (A-B) is -√5/5

Answer:  20, 70, 90

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

Work Shown:

Let x be some positive real number.

Multiply each part of the given ratio by x to get 2x:7x:9x

So we have the three angles 2x, 7x, and 9x.

For any triangle, the three angles must add to 180

2x+7x+9x = 180

18x = 180

x = 180/18

x = 10

This leads to

The three angles of this triangle are: 20, 70, 90

This is a right triangle due to the 90 degree angle.
