Answer:

334.4 m²

Step-by-step explanation:

The formula for the area of a sector is given as:

1/2 × r² × θ

Where θ = Central angle

Area of a Circle = 700 m²

The formula for the area of a circle = πr²

r = Radius of a circle

r² = Area / π

r = √Area / π

r = √700/π

r = 14.927053304 m

Approximately, r = 14.93 m

Therefore, the area of the sector

= 1/2 × r² × θ

= 1/2 × 14.93² × 3 rad

= 334.35735 m²

Approximately, Area of the sector = 334.4 m²

An executive drove home at an average speed of 30 mph to an airport where a helicopter was waiting. The executive boarded the he
wlad13 [49]

Answer:

120 miles

Step-by-step explanation:

Formulate equations.

Distance = rate * time.

D1 = distance from home to airport

D2 = distance from airport to off

D1 + D2 = 150

30 x t1 + 60 x t2 = 150

Divide through by 30

t1 + 2t2 = 5 ----- equation 1

Entire trip took 3 hours

t1 + t2 = 3 -------------------- equation 2

Solve equation 1 and 2 and you get

t1 = 1 hour

t2 = 2 hour

D2 = t2 x speed = 2 x 60

          = 120 miles.

Percent change of the numbers six and four
dangina [55]

Answer:

%60.66666...

Step-by-step explanation:

<u>Step 1:  Make an equation to represent</u>

Percent change of the numbers six and four

6x = 4

<u>Step 2:  Divide both sides to get a decimal</u>

6x / 6 = 4 / 6

x = 0.6666....

<u>Step 3:  Convert into a percentage</u>

x = 0.6666.... * 100

x = %60.66666...

Answer:  %60.66666...

<u>If you meant the other way:</u>

4x = 6

4x / 4 = 6 / 4

x = 1.5

x = 1.5 * 100

x = %150
