PLS HELP AND HURRY !!!!!! ​

OA, OB, and OC are all radii of the circle so they have the same length, 12 in. ∆ AOB is therefore isosceles, so the angles at the vertices A and B are congruent. The interior angles of any triangle sum to 180° in measure, so

30° + 2 m∠A = 180°   ⇒   m∠A = 75°

Draw an altitude in ∆ AOB that connects the vertex O to the midpoint of AB; this is the height h of ∆ AOB and bisects ∆ AOB into two 15°-75°-90° right triangles. Solve for h and the length of the base AB using trigonometry:

sin(15°) = (AB/2) / (12 in)   ⇒   AB = (24 in) sin(15°) ≈ 6.212 in

sin(75°) = h / (12 in)   ⇒   h = (12 in) sin(75°) ≈ 11.591 in

Then the area of ∆ AOB is

1/2 (AB) h = (144 in²) sin(15°) sin(75°)

= (72 in²) (cos(60°) - cos(90°))

= 36 in²

where we use the identity

sin(x) sin(y) = 1/2 (cos(x - y) - cos(x + y))

Let m∠BOC = θ. Then

(area of sector BOC) / θ = (area of ⊙O) / 360°

Solve for θ :

θ = (area of sector BOC) / (area of ⊙O) • 360°

θ = (36 in²) / (π (12 in)²) • 360°

θ = (90/π)° ≈ 28.648°

Answer:

2010

Step-by-step explanation:

Using the stated percentage, it is determined that it has a 0.877 = 87.7% chance of arriving on time.

The number of desired outcomes divided by the total number of outcomes yields a probability.

A percentage can be regarded as a probability over a big sample.

In this question, 87.7% of flights arrive on time in Atlanta, based on a significant number of flights. As a result, there is a 0.877 = 87.7% chance that it will arrive on time.

Answer:

s = [tex]\frac{19}{4}[/tex]

Step-by-step explanation:

substitute the given values into the equation

s = (10 × [tex]\frac{1}{2}[/tex] ) + ( [tex]\frac{1}{2}[/tex] × - 2 × ([tex]\frac{1}{2}[/tex] )² )

  = 5 + (- 1 × [tex]\frac{1}{4}[/tex] )

  = 5 - [tex]\frac{1}{4}[/tex]

  = 4 [tex]\frac{3}{4}[/tex]

  = [tex]\frac{19}{4}[/tex]

The amount that marcus end up paying for the two shirts originally priced  at $28.99 and $30.29 is given by: Option A: $39.59

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, we're given that:

Cost of two shirts originally is $28.99 and $30.29

30% is off on each of them, so we get:

New price of each shirt = Old price of each shirt - 30% of old price of each shirt

New price of each shirt = [tex]28.99 - \dfrac{28.99}{100} \times 30[/tex] and [tex]30.29- \dfrac{30.29}{100} \times 30[/tex]

This sums up to $41.496

Now, at this price, there'd be application of 10% additional discount.

That will make the new price as:

[tex]41.496 - \dfrac{41.496}{100} \times 10 =37.3464[/tex]

Now, on this price, there'd be applied 6% sales tax

So, the amount he paid for 2 shirts = discounted price + 6% tax on discounted amount

= [tex]37.3464 + \dfrac{37.3464}{100} \times 6 \approx 39.59 \: \rm dollars[/tex]

Thus, the amount that marcus end up paying for the two shirts originally priced  at $28.99 and $30.29 is given by: Option A: $39.59

Answer:

y = 3x - 3

Step-by-step explanation:

Given, (2,3) and (-1,9), m = 3

Equation of a straight line is y = mx + c

Here, y = 3, x = 2 and m = 3

Substituting the values in y = mx + c we get,

3 = 3(2) + c

c + 6 = 3

c = 3 - 6

c = -3

So, the equation of the line is y = 3x - 3  (Answer).
