Answer:

85 points

Step-by-step explanation:

His total points will be 235+x

Number of tests will be 4

(235+x)/4 = 80

multiply by 4

235+x= 4*80

235+x= 320

x=320-235

x= 85

He has to get 85 points to average 80

We know that:

Finding the area of the circle:

Answer:

942ft^2

Step-by-step explanation:

Use the equation (θ/360)*[tex]\pi[/tex][tex]r^{2}[/tex] to get the area of the shaded sector.

(120/360)*[tex]\pi[/tex]*[tex]30^{2}[/tex]

(1/3)*[tex]\pi[/tex]*900

≈942[tex]ft^{2}[/tex]

The area of the shaded region is 942 square ft if the radius of the circle is 30 ft option (G) is correct.

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

We have a circle shown in the picture.

The area of the shaded region:

[tex]\rm A = \dfrac{120}{360}\pi (30)^2[/tex]

A = 942.47 ≈ 942 square ft

Thus, the area of the shaded region is 942 square ft if the radius of the circle is 30 ft option (G) is correct.

Answer:

B

Step-by-step explanation:

The Law of Sines states that

sinA/a = sinB/b = sinC/c

We know A, a, and b. Given this, we can solve for B, and given that, we can solve for C and then c.

First, we solve for B.

sinA/a = sinB/b

sin(15°)/6 = sinB/8

sin(15°)/6 * 8 = sinB

arcsin(sin(15°)/6 * 8) = B ≈ 20.187

Note that there can be a second B value. We can check if there is a second B value by first subtracting the B value we got from 180.

180 - 20.187 = 159.813

Next, we can add that to our existing angle, A = 15°. If that is less than 180, then we do have a second solution. 159.813 + 15 = 174.813 < 180 so there does exist a second solution where B = 159.813

Next, we can solve for C.

We know that the angles in a triangle add to 180°, so A + B + C = 180. Therefore, for the first solution:

15 + 20.187 + C = 180

C = 180 - 15 - 20.187 = 144.813°

and for the second:

15 + 159.813 + C = 180

C = 180 - 15 - 159.813 = 5.187

Finally,

sinA/a = sinC/c

multiply both sides by c to no longer have it as a denominator

sinA * c / a = sinC

divide both sides by (sinA/a) to isolate c

for the first solution:

c = sinC*a/sinA = 13.35868 ≈ 13.36

and for the second:

c = sinC*a/sinA ≈ 2.10

Answer: m<D = 30

Step-by-step explanation: In the third step of the problem, it says that E is next to itself and equals 90. However, this is not true. Angle BEA and angle CED are vertical angles and are both equal to 65°. This means that to find the measurement of angle D, subtract 65 and 85 from 180, which equals 30.

Divide total price by number of pencils:

23.28 / 24 = $0.97 per pencil

Answer:

x = 29°, y = 61°

Step-by-step explanation:

x + 61 = 90

Because of the right angle symbol

x = 90 - 61

x = 29°

x + y = 90

Because vertically opposite angles are equal

29 + y = 90

y = 90 - 29

y = 61°

let y = volume of water in gallons

when x = 0, y = 7

when x = 3, y = 5

[tex]\mathsf{rate \ of \ change \ = \dfrac{change \ in \ y}{change \ in \ x}=\dfrac{7-5}{0-3}=-\dfrac23 \ gallons/min}[/tex]
