Answer:

130

Step-by-step explanation:

[tex]2x \degree + 460 \degree = (6 - 2) \times 180 \degree \\ \\ 2x \degree + 460 \degree =4 \times 180 \degree \\ \\ 2x \degree + 460 \degree =720 \degree \\ \\ 2x \degree =720 \degree -460 \degree \\ \\ 2x \degree =260 \degree \\ \\ x \degree= \frac{260\degree}{2} \\ \\ x \degree= 130 \degree \\ \\ x = 130[/tex]

Answer:

A is the answer

Step-by-step explanation:

Answer:

Step-by-step explanation:

a+c=62, c=62-a

7a+3.5c=364, using c found above gives you

7a+3.5(62-a)=364 expand left side

7a+217-3.5a=364 group like terms on left side

3.5a+217=364 subtract 217 from both sides

3.5a=147 divide both sides by 3.5

a=42, since c=62-a

c=62-42=20

So 20 children and 42 adult tickets were sold.

Answer:

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

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

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).

       3r^3

w = ---------

         64

Answer:

[tex]x=4[/tex]

Step-by-step explanation:

By the Triangle Proportionality Theorem:

[tex]\displaystyle \frac{x}{12}=\frac{x+1}{15}[/tex]

By cross-multiplication:

[tex]\displaystyle 12(x+1)=15(x)[/tex]

Distribute:

[tex]12x+12=15x[/tex]

Subtract 12x from both sides:

[tex]12=3x[/tex]

Hence:

[tex]x=4[/tex]

Answer:

4

Step-by-step explanation:

The first thing you should notice is that the triangles (the smaller one and the larger one) are similar due to angle-angle similarity (the top angle equals itself, and because the bases are parallel lines cut by a transversal, the base angle of the bigger triangle is equal to the corresponding base of the smaller triangle.

Similar triangles' corresponding sides have equal ratios to one another. That means we can set up an equation: side of smaller triangle ÷ corresponding side of larger triangle = other side of smaller triangle ÷ corresponding side of larger triangle. We plug the values given to us and can change this equation to:[tex]\frac{x}{x + 12} = \frac{x + 1}{x + 16}[/tex] **

We now multiply both sides of the above equation by [tex](x + 12)(x + 16)[/tex] to get: [tex]x(x + 16) = (x + 1)(x + 12)[/tex]

[tex]x^{2} + 16x = x^{2} + 13x + 12[/tex]

[tex]3x = 12[/tex]

[tex]x = 4[/tex]

That means our answer, for the value of x, is 4

** Make sure you don't say [tex]\frac{x}{12} = \frac{x + 1}{15}[/tex], because those aren't the sides of the larger square.
