Answer:

B. 54°

Step-by-step explanation:

There are 360° in a circle and sector 4 consists of 15% of it.

We just have to multiply the 2 numbers.

15% = 0.15

0.15(360) = 54

Answer:

adult $13   student $15

Step-by-step explanation:

A=adult        S = student

9A + 4S = 177

1A + 4S =  73

Multiply the second by (-1)

9A +4S = 177

-1A -4S = -73

ADD BOTH (4S will be cancelled)

  8A = 104

   A = 13      ( Adult ticket = $13)

13 + 4S = 73

4S = 60

S = 15  ( student ticket $15)

Answer:

x=7

Angle = 102

Step-by-step explanation:

Both angles are congruent, meaning they have the same measure.

Set your formula up as

15x-5=13x+9

15x=13x+9+5

15x-13x=9+5

2x=14

x=14/2

x=7

Now plug in 7 for x

15x-3

15*7-3

Answer:  $19,864.60

Step-by-step explanation:

The future value formula could have been used to find the price in the 6th year. As we now know the price, the formula can now be used to find the original price.

Price at 6th year = Original price * ( 1 + rate) ^ number of years

12,045 = Og * ( 1 - 8%) ⁶

12,045 = Og * 0.606355001344

Og = 12,045 / 0.606355001344

Og = $19,864.60

Rate is subtracted because price was reducing.

Step-by-step explanation:

By the Midpoint Theorem, the argent that connects midpoints of the sides of a triangle equals half the parallel side. That said,

Step-by-step explanation:

L= W+5

P= 9W

P= 2L+ 2W

9W= 2(W+5) + 2W

9W= 2W +10 +2W

9W = 4W +10

5W = 10

W = 2

L=7

P= 9(2)

P= 18

Step-by-step explanation:

Answer:

6 1/10

Step-by-step explanation:

Add 4 1/2 and 1 3/5. To add that, you need to multiply the denominators and the numerators, in this case that equals 10. So then add the fractions first 5/10+ 6/10=11/10. Since that is an improper fraction, add +1 to the hole numbers, so you answer would be 6 1/10

Answer:

[tex]<D=95[/tex]

Step-by-step explanation:

The opposite angles in a quadrilateral theorem states that when a quadrilateral is inscribed in a circle, the angles that are opposite each other are supplementary, their degree measures add up to 180 degrees. One can apply this here by using the sum of (<C) and (<A) to find the measure of the parameter (z). Then one can substitute in the value of (z) to find the measure of (<B). Finally, one can use the opposite angles in a quadrilateral theorem to find the measure of angle (<D) by using the sum of (<B) and (D).

Use the opposite angles in an inscribed quadrialteral theorem,

<A + <C = 180

Substitute,

14x - 7 + 8z = 180

Simplify,

22z - 7 = 180

Inverse operations,

22z = 187

z = [tex]\frac{187}{22}[/tex]

Simplify,

z = [tex]\frac{17}{2}[/tex]

Now substitute the value of (z) into the expression given for the measure of angle (<B)

<B = 10z

<B = 10([tex]\frac{17}{2}[/tex])

Simplify,

<B = 85

Use the opposite angles in an inscribed quadrilateral theorem to find the measure of (<D)

<B + <D = 180

Substitute,

85 + <D = 180

Inverse operations,

<D = 95

   V = pi(7)^2(20)

   V = 3078.76

8. Same formula as 7.

10. Same formula again

V = 62.83

11. V = 4/3*pi(r)^3

    V = 4/3*pi(6)^3

Answer:

C. g(x) = -|x|

Step-by-step explanation:

|x| is an upwards v centered at the origin

- |x| is a downwards v centered at the origin

A central angle has a measure of 1 radian if the length of the intercepted arc is the same as the length of the radius.

One radian is the measure of a central angle that intercepts an arc s equal in length to the radius r of the circle. Since the circumference of a circle is 2πr, one revolution around a circle of radius r corresponds to an angle of 2π radians because of sr⇒2πrr=2π radians.

Answer:

x = 4

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

(19x + 3)° is an exterior angle of the triangle, then

11x - 2 + 9x + 1 = 19x + 3

20x - 1 = 19x + 3 ( subtract 19x from both sides )

x - 1 = 3 ( add 1 to both sides )

x = 4
