A basketball team played 15 games and won 80% of them. If the team expects to play 30 games in all, how many more games must it win to finish the season with a 90% winning percentage?

Answer:

Step-by-step explanation:

Picture 1

In right triangle ABC,

Side AB is the opposite side of angle C.

Picture 2

In triangle MKL,

tan(∠M) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

             = [tex]\frac{KL}{KM}[/tex]

             = [tex]\frac{15}{8}[/tex]

Option (1) is the answer.

Picture 3

In ΔXYZ,

sin(∠Z) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

            = [tex]\frac{XY}{XZ}[/tex]

For the length of XY we will apply Pythagoras theorem in ΔXYZ,

XZ² = XY² + YZ²

XY² = XZ² - YZ²

      = (40)² - (32)²

XY = √576

     = 24

sin(Z) = [tex]\frac{24}{40}[/tex]

sin(Z) = [tex]\frac{3}{5}[/tex]

Picture 4

In right triangle DEF,

Cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

           = [tex]\frac{EF}{DF}[/tex]

           = [tex]\frac{75}{72}[/tex]

           = [tex]\frac{25}{24}[/tex]

Picture 5

In ΔABC,

tan(63°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(63°) = [tex]\frac{BC}{AB}[/tex]

AB = [tex]\frac{BC}{\text{tan}(63)}[/tex]

AB = [tex]\frac{8}{\text{tan}(63)}[/tex]

AB = 4.0762 ≈ 4 m

Option (3) will be the answer.

Answer:

2 9/14

Step-by-step explanation:

first we must make 1/6 and 3/7 have common demoniaters! (or however u spell it)

1/6 x 7/7 = 7/42

3/7 x 6/6 = 18/42

7/42 + 18/42 = 25/42

2/7 x 6/6 = 12/42

25/42 + 12/42 = 37/42

37/42 + 7/42 = 44/42

44/42 + 18/42 = 62/42

62/42 + 12/42 = 74/42

5/7 x 6/6 = 30/42

74/42 + 30/42 = 104/42

104/42+7/42 = 111/42

111/42 = 2 9/14

Answer:

IQR = 10

Step-by-step explanation:

1. Find the median (middle data point.)

2. Find the median of the upper quartile (70 - 80.)

3. Find the median of the lower quartile. (60 - 70.)

4. Subtract the lower quartile from upper quartile.

1. median of the data = 70

2. median of Q2 = 75

3. median of the Q3 = 65

4. 75 - 65 = 10

IQR = 10

What is an Equation?

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.

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 data ,

Let the number of campers who voted for hot dogs = 5 campers

Let the number of campers who voted for sphagetti = 4 campers

Now , the total campers = 5 + 4

                                        = 9 campers

5 out of 9 campers vote for hot dogs

So ,

The total number of campers = 72 campers

The equation will be ,

The total number of campers who voted for hotdogs =
( number of campers who voted for hot dogs / the total campers ) x 72

The total number of campers who voted for hotdogs = ( 5 / 9 ) x 72

                                                                                        = 5 x 8

The total number of campers who voted for hotdogs = 40 campers

Hence , The number of campers who voted for hotdogs is 40 campers

Answer:

x = 12y + 1

y = Jenny's score

Answer:

2 miles.

Step-by-step explanation:

In this case, we would multiply the numerator by 3 since we know that it takes him 10 minutes to run 2/3 of a mile. So, 2x3 = 6. Which gives us 6/3. Simplified that would be 2 miles. Hope this helps!

Answer:

a) Given that w=81 and k = 0.375 then r = 6

b)  Given that s=27 and k = 224 then w=32

Step-by-step explanation:

Step(i):-

Given that W varies directly as r³

      ⇒ w∝r³

    ⇒   w = kr³

where 'k' is proportionally constant

given that w= 24 and r =4

     ⇒  24 = k (4)³

     ⇒ k = [tex]\frac{24}{64}[/tex]

    ⇒ k = 0.375

Step(ii):-

Given that W varies indirectly as 's'

            w ∝[tex]\frac{1}{s}[/tex]

            W =k [tex]\frac{1}{s}[/tex]

where 'k' is proportionally constant

          28 = k ([tex]\frac{1}{8}[/tex])

        k = 28 × 8 = 224

Step(iii):-

a) Given that w=81 and k = 0.375

     w = kr³

   81 = 0.375 (r)³

   r³ = 216

  r = ∛216 =6

 r =6

b)

 Given that s=27 and k = 224

          W =k [tex]\frac{1}{s}[/tex]

         w = 224 ([tex]\frac{1}{27}[/tex])

        w = 32

Answer:

2√3

Step-by-step explanation:

In a special right triangle called the 30-60-90 triangle, the ratios of the side lengths are x-x√3- 2x respectively. This means that the side opposite to the 60 degrees is x√3 and the side opposite to the 30 degrees is x.

Since the side opposite to the 60 degrees is 6, x√3=6

x√3=6

x=6/√3

rationalize the denominator:

6√3/3

Answer:

x = 62.1

Step-by-step explanation:

Note the equal sign in this equation, what you do to one side, you do to the other. Isolate the variable, x, by dividing 10 from both sides of the equation:

[tex]621 = 10x\\\\\frac{621}{10} = \frac{10x}{10} \\\\x = \frac{621}{10} \\x = 62.1[/tex]

Translating the word problem into a symbolic statement:  W = kr³/s.  Find k by letting W = 24, r = 4 and s = 8:

         k·4³

24 = --------            

           8

This reduces to 3 = 4^3*k, or 3 = 64k, or k = 3/64 (the constant of proportionality).

A) To make a decision on where to park depends on

B) Option 1 is most cost effective when the  parking time is ≥ 3hours

while Option 2 is most cost effective when the parking time is ≤ 30 minute

Step-by-step explanation:

A) To make a decision on where to park depends on

B)

lets assume you will be parked for 30 minutes before picking up your friend

For option 1

You will spend $5 and also get a free shuttle to the terminal

For option 2

You will spend $2  

Therefore Option 2 is better

Lets assume you will be parked for 3 hours  before pick up

For option 1

You will spend $5 and also get a free shuttle

For option 2

You will spend ; $2 for the first 30 minutes + $10 for the remaining 2hours 30 minutes

Therefore Option 1 is better.

Option 1 is most cost effective when the  parking time is ≥ 3hours

while Option 2 is most cost effective when the parking time is ≤ 30 minutes
