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:2

Step-by-step explanation:

[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]

[tex]x= -y[/tex]

Substitute x as -y.

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

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

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

Step-by-step explanation:

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:

  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

Answer:

Step-by-step explanation:

1/6 x 12 = 2

2/3 x 12 = 8

8 + 2 = 10

12 - 10 = 2

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.

Step-by-step explanation:

=> x + 80 + 20 = 180

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

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

Explanation:

θ = greek letter theta = reference angle

Using the unit circle, you should find that when θ is pi/3, we have

Dividing sine over cosine gets us tangent

tan(θ) = sin(θ)/cos(θ) = sqrt(3)/2 divide over (1/2) = sqrt(3)

Effectively, the denominators '2' cancel out when dividing the two fractions. The result we get here is not sqrt(3)/2, so we can rule out choice A.

---------------

Choice B can be ruled out because

cos(0) = 1

sin(0) = 0

So,

tan(0) = sin(0)/cos(0) = 0/1 = 0

which doesn't match with y = pi

----------------

Following the same ideas as mentioned before:

cos(pi/4) = sqrt(2)/2

sin(pi/4) = sqrt(2)/2 ... it's not a typo, sine and cosine are the same here

tan(pi/4) = 1 after dividing the two items above

We end up with y = 1 as the screenshot shows, so (pi/4, 1) is one point on the graph of y = tan(x).

Choice C is one of the answers

----------------

Choice D however is not one of the answers because

sin(pi/2) = 1

cos(pi/2) = 0

tan(pi/2) = undefined, because the denominator cosine is 0 in this case

So there's a vertical asymptote at x = pi/2 for y = tan(x)

-----------------

Choice E is another answer, because,

sin(pi) = 0

cos(pi) = -1

tan(pi) = sin(pi)/cos(pi) = 0/(-1) = 0

This shows (pi, 0) is a point on y = tan(x).

The graph is shown below. Points C and E are on the blue tangent curve, while everything else isn't.

I used GeoGebra to create the graph. Desmos is also a handy tool that can perform similar tasks.

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°

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

₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩₩

YV = 6x + 21 = 9x + 3
