Answer:

it would be number A. number 1

YS = 2/3 × ( YV ) *.&.* SV = 1/3 × ( YV )

_____________________________

YS = 2/3 × ( YV )

4x + 14 = 2/3 × ( YV )

Multiply both sides by 3/2

( 4x + 14 ) × 3/2 = ( YV ) × 2/3 × 3/2

YV = 6x + 21 ( ☆ )

¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥

SV = 1/3 × ( YV )

1 + 3x = 1/3 × ( YV )

Multiply both sides by 3

( 1 + 3x ) × 3 = ( YV ) × 1/3 × 3

YV = 9x + 3 ( ♡ )

_____________________________

YV = YV

( ☆ ) = ( ♡ )

6x + 21 = 9x + 3

Subtract both sides 3

6x + 21 - 3 = 9x + 3 - 3

6x + 18 = 9x

Subtract both sides 6x

6x - 6x + 18 = 9x - 6x

18 = 3x

Divide both sides by 3

18 ÷ 3 = 3x ÷ 3

x = 6

Answer:

  A.  0 = −(x−6)^2+12

Step-by-step explanation:

The vertex form of a quadratic equation is ...

  y = a(x -h)² +k . . . . . . for vertex (h, k) and scale factor 'a'

When the given vertex (h, k) = (6, 12) is used, we find the form of the equation to be ...

  y = a(x -6)² +12

The ball will be on the ground when y = 0. Here, the vertical scale factor 'a' is -1, so the equation representing the ball being on the ground is ...

  0 = -(x -6)² +12 . . . . . . matches choice A

wow, hardest question I've ever answered! It's either 4 or 22, I can't decide

Step-by-step explanation:

Answer:

5. x = 5, y = 3

6. x = 0, y = 4

7. x = -1, y = 1

Step-by-step explanation:

5. substitute 3(value of y) into the equation y = x - 2:

=> 3 = x - 2

=> x = 5

6. substitute 0(value of x) into the equation y = x + 4:

=> y = 0 + 4

=> y = 4

7. substitute 1(value of y) into the equation y = 2x + 3:

=> 1 = 2x + 3

=> 2x = -2

=> x = -1

[tex]\begin{bmatrix}4x+4y=0\\ -4x-4y=0\end{bmatrix}[/tex]

Subtract 4y from both sides.

[tex]4x+4y-4y=0-4y[/tex]

Simplify

[tex]4x=-4y[/tex]

Divide each side by 4

[tex]\frac{4x}{4}=\frac{-4y}{4}[/tex]

Simplify

[tex]x= -y[/tex]

Substitute x as -y.

[tex]\begin{bmatrix}-4\left(-y\right)-4y=0\end{bmatrix}[/tex]

[tex]0=0[/tex]

The values of x and y are both zero.

Answer:

arc AC = 202°

Step-by-step explanation:

Based on the tangent-angle secant rule, the angle formed outside a circle by a secant and a tangent is equal to one-half the difference between the far arc and the near arc.

Thus:

m<P = ½(arc AC - arc CB)

Substitute

78° = ½(arc AC - 46°)

Multiply both sides by 2

2*78 = arc AC - 46

156 = arc AC - 46

Add 46 to both sides

156 + 46 = arc AC

202° = arc AC

arc AC = 202°

Answer:

For each table plug x in one at a time into the equation

If the outcome (y) is the same in the table that will be the correct answers

Step-by-step explanation:

For example -2 will be plugged in so y=5/4(-2)-3 which simplifies down to -0.5 looking back at the table we see the y value is 0.5 instead of -0.5 thus allowing us to eliminate that answer choice and repeat the process in the next table. Whichever one holds true and have the correct outcome will be the correct answer

Answer:

[tex](a)\ r = 8cm[/tex]

[tex](b\ Area = 200.96cm^2[/tex]

[tex](c)\ Volume = 2143.573cm^3[/tex]

Step-by-step explanation:

The largest cross-section of a sphere is the center.

So, we have:

[tex]A : C = 4 : 1[/tex]

Where

[tex]A = \pi r^2[/tex]

[tex]C =2\pi r[/tex]

Solving (a): The radius

[tex]A : C = 4 : 1[/tex] implies that

[tex]\pi r^2 : 2\pi r = 4 : 1[/tex]

Express as fraction

[tex]\frac{\pi r^2 }{ 2\pi r} = \frac{4 }{ 1}[/tex]

[tex]\frac{\pi r^2 }{ 2\pi r} = 4[/tex]

Divide by [tex]\pi r[/tex]

[tex]\frac{r}{ 2} = 4[/tex]

Make r the subject

[tex]r = 4 * 2[/tex]

[tex]r = 8cm[/tex]

Solving (b): Area of the largest cross-section.

[tex]Area = \pi r^2[/tex]

[tex]Area = 3.14 *8^2[/tex]

[tex]Area = 200.96cm^2[/tex]

Solving (b): Volume of the sphere

[tex]Volume =\frac{4}{3}\pi r^3[/tex]

[tex]Volume =\frac{4}{3} * 3.14 * 8^3[/tex]

[tex]Volume = 2143.573cm^3[/tex]

Answer:

(29-23)²/23 + (16-23)²/23 + (19-23)²/23 + (28-23)²/23

Step-by-step explanation:

Given :

n(American) = 29

n(Chinese) = 16

n(Mexican) = 19

n(Italian) = 28

Expected value = (29 + 16 + 19 + 28) / 4

Where, 4 = sample size

Expected value, E = 23

χ² = (Observed value - Expected value)² / expected value

χ² = (29-23)²/23 + (16-23)²/23 + (19-23)²/23 + (28-23)²/23

Answer:

(29-23)²/23 + (16-23)²/23 + (19-23)²/23 + (28-23)²/23

Answer:

75 games

Step-by-step explanation:

5 : 3 =8

8 = 120 games

1= 120÷8

=15

Games the team win:

= 5×15

= 75 games

If  team's win-loss ratio was 5 to 3. If the team played 120 games without a tie then 75 games are win by team.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

The team's win-loss ratio was 5 to 3.

The team played 120 games without a tie.

We need to find how many games did the team win

5x+3x =8x

8x = 120 games

Divide both sides by 8

x= 120/8

x=15

Games the team win:

= 5×15

= 75 games

Hence, 75 games did the team win.

Answer:PLZ MARK BRAINLIST

Draw a line from the center of the circle to the chord to form a right triangle.

The radius (20) forms the hypotenuse of the right triangle and distance from the center to the chord (16) forms a leg.

Use the Pythagorean Theorem to find the length of the other leg x (which would be 1/2 the length of the chord):

x^2 + 16^2 = 20^

x = 12

So the entire chord length = 12 * 2 = 24 units

Answer:

2 not wearing either blue or white

Step-by-step explanation:

Find out the fraction that represents those that are wearing either blue or white. Let x be that fraction

x = 2/3 + 1/6

Change 2/3 and 1/6 to 12ths. because there are 12 students in the class.

2/3 = 2*4 / (4 *O 4) = 8/12

1/6 = 2*1/(2 * 6) = 2 / 12

x = 8/12 + 2/12

x = 10/12   Normally you would reduce this fraction because we are not using the Lowest common Denominator. In this case we just leave it.

There are 12/12 - 10/12 = 2/12 that are missing.

So 2 people are Not wearing either blue or white.
