Answer: A. 9

Step-by-step explanation:

In the given tree diagram , there are 3 branches , to each branch there are 3 leaf nodes.

By using Fundamental counting principal ,

Number of possible outcomes for the tree diagram = (Number of branches) x (Number of leaf nodes)

[tex]=3 \times 3\\\\=9[/tex]

Hence, the number of possible outcomes for the tree diagram = 9

So, the correct option is A. 9.

Answer: 1/2, 2/10, and 3/15

Explanation: Let's find 3 fractions that are equivalent to 4/20.

To find 3 fractions that are equivalent to 4/20,

notice that 4/20 is not in lowest terms.

In this situation, let's first rewrite 4/20 so that it's in lowest terms.

To do this, we divide the numerator and denominator by the

greatest common factor of 4 and 20, which is 4, and we have 1/5.

Since 1/5 is equivalent to 4/20, we can use

1/5 to find more equivalent fractions.

If we multiply 1/5 by 2 in both the numerator and

denominator, we get the equivalent fraction 2/10.

If we multiply 1/5 by 3 in both the numerator and

denominator, we get the equivalent fraction 3/15.

So 4/20 is equivalent to 1/5, 2/10, and 3/15.

Note that these are just 3 possible answers.

There are many other fractions that are also equivalent to 4/20.

Answer:

The diameter is 1.

Step-by-step explanation:

The circumference is 3.14 units

C = pi * d

Using 3.14 for pi

3.14 = 3.14 d

Divide each side by 3.14

3.14/3.14 = 3.14 d/ 3.14

1 =d

The value of x is 5 and y is 4.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

The Equations are:

5x - 12y= -8...................(1)

and, 5 x + 2 y = 48 ..................(2)

Solving the Equation (1) and (2) we get

-12y -2y = -8 - 48

-14y = -56

y= -56 /(-14)

y = 4

and, 5x +2y= 48

5x + 8 = 48

Answer:

Step-by-step explanation:

We have a right triangle. Therefore, we can use the Pythagorean theorem:

The sum of the areas of the squares built on the legs is equal to the area of ​​the square built on the hypotenuse.

We have the area of the largest square (the square built on the hypotenuse).

A₃ = 36 u²

From the Pythagorean therem we have the equation:

A₃ = A₁ + A₂

We need the areas of the smaller squares (A₁ and A₂).

A₁ + A₂ = 36.

From the second picture, we have:

A) 6 and 30 → 6 + 30 = 3          CORRECT

B) 8 and 28 → 8 + 28 = 36       CORRECT

C) 4 and 16 → 4 + 16 = 20 ≠ 36  INCORRECT

Answer:

12 cm

Step-by-step explanation:

You would only have to focus on the green line and then you just have to divide it by 12 and you get 4 and than you multiply 3 cm by 4 and the answer for the actual length of the green line will be 12 cm.

Answer:

12 cm

Step-by-step explanation:

The ratio of feet to cm is 12:3. Set up a ratio to find the length of the green line in cm.

12 feet ÷ 3 cm = 48  ft ÷ x

Cross multiply and divide.

3 x 48 = 12 × x

144 = 12x

x = 12

The actual length of the green line is 12 cm.

Answer:

x=25°

Step-by-step explanation:

sin (x+22)=cos(2x-7)=sin (90-(2x-7))

x+22=90-(2x-7)

x+22=90-2x+7

x+2x=97-22

3x=75

x=75/3=25°

Answer:

x = 25

Step-by-step explanation:

Recall the trig identity sin(x) = cos(90 - x)

In other words, sin(x + 22) = cos(90 -(x+22)) = cos(68 - x)

Now, set them equal to each other:

cos(68 - x) = cos(2x - 7)

We can ignore the cosine:

68 - x = 2x - 7

3x = 75

x = 25

Answer:

35 red marbles

Step-by-step explanation:

So we can put the different color marbles in a ratio. So 7:2:11. If we add all of those up we get 20. We do 100/20 to get 5. Each number in the ratio is equivalent to 5 marbles. Then we do 7*5 to get 35. We can check our work by doing, (7*5) + (2*5) + (11*5) = 100. And it does equal 100 so the answer is correct.

Answer:

35 red marbles

Step-by-step explanation:

The total number of marbles the student recorded is 20

Now we have to make a ratio of red to the total number of marbles

That would be 7 : 20

After this, there will be a new ratio which is x : 100

Lastly we will solve for x making the equation 20x = 700, x = 35

B. 1 must be a root of the polynomial 3x^2+x-4

Step-by-step explanation:

Given polynomial

3x^2+x-4

Divided by factor x-1

Gives a remainder of 0

Remainder 0 represents that divisor (x-1) is a factor polynomial 3x^2+x-4

If x-1 is a factor of the polynomial, we can equate x-1 to 0

x-1=0

Solve for x to get one of the roots

x-1=0

Add 1 to both sides

x-1+1=0+1

x=1

B. 1 must be a root of the polynomial 3x^2+x-4

The linear factors are:

Step-by-step explanation:

Given

[tex]x^3 + 2x^2 - 5x - 6[/tex]

Required

Select all linear factors of the polynomial

Solving for x - 2;

Equate x - 2 to 0 and solve for x

[tex]x - 2 = 0[/tex]

[tex]x = 2[/tex]

Substitute 2 for x in [tex]x^3 + 2x^2 - 5x - 6[/tex]

[tex]2^3 + 2(2^2) - 5(2) - 6[/tex]

[tex]= 8 + 8 - 10 - 6[/tex]

[tex]= 0[/tex]

Because, we arrived at 0, then x - 2 is a factor

Solving for x + 3;

Equate x + 3 to 0 and solve for x

[tex]x + 3 = 0[/tex]

[tex]x = -3[/tex]

Substitute -3 for x in [tex]x^3 + 2x^2 - 5x - 6[/tex]

[tex](-3)^3 + 2(-3^2) - 5(-3) - 6[/tex]

[tex]= -27 + 2(9) + 15 - 6[/tex]

[tex]= -27 + 18 + 15 - 6[/tex]

[tex]= 0[/tex]

Because, we arrived at 0, then x + 3 is a factor

Solving for x - 1;

Equate x - 1 to 0 and solve for x

[tex]x - 1 = 0[/tex]

[tex]x = 1[/tex]

Substitute 1 for x in [tex]x^3 + 2x^2 - 5x - 6[/tex]

[tex](1)^3 + 2(1^2) - 5(1) - 6[/tex]

[tex]= 1 + 2(1) - 5 - 6[/tex]

[tex]= 1 + 2 - 5 - 6[/tex]

[tex]= -8[/tex]

Because, we did not arrived at 0, then x - 1 is not a factor

Solving for x + 1;

Equate x + 1 to 0 and solve for x

[tex]x + 1 = 0[/tex]

[tex]x = -1[/tex]

Substitute -1 for x in [tex]x^3 + 2x^2 - 5x - 6[/tex]

[tex](-1)^3 + 2(-1^2) - 5(-1) - 6[/tex]

[tex]= -1 + 2(1) + 5 - 6[/tex]

[tex]= -1 + 2 + 5 - 6[/tex]

[tex]= 0[/tex]

Because, we arrived at 0, then x + 1 is a factor

Answer for problem 1: slope = 2, y intercept = 3

Answer for problem 2: slope = 3/4, y intercept = -2

Explanation:

Both equations are in the form y = mx+b. This is known as slope intercept form. This is because we can read off the values of the slope and y intercept very quickly. We have y = 2x+3 match up with y = mx+b. The m is the slope and b is the y intercept. So m = 2 and b = 3 for this equation. A similar situation happens with the other equation as well. It might help to rewrite the second equation into y = (3/4)x + (-2).

We can then identify the like terms:

>>> term in [tex]x^2\\[/tex]

   A = 5

   6 = 6

As we know that A=5 it means that B = -2*5-3=-13

Answer:

B = -13

Step-by-step explanation:

Nothing is wrong you just have to complete it..

soo continuing from where you stopped.

Ax² - 2Ax - 3x + 6 = 5x² + Bx + 6

(its supposed to be the equivalence sign [with three dashes] but I am restricted by my keypad, so I made use of the equal to sign [two dashes])

comparing both sides, we can therefore say:

Ax² = 5x²..............i

- 2Ax - 3x = Bx......ii

+6 = +6..............iii

sub the value of A = 5 into ......ii

-2Ax - 3x = Bx

-2(5)x - 3x = Bx

-10x - 3x = Bx

-13x = Bx

B = - 13
