Answer:

21870 km^2

Step-by-step explanation:

Area of sector=1/2r^2(theta)

Where r=18 km and theta=135

Area of sector=1/2(18)^2(135)

=1/2(324)(135)

=1/2(43740)

=21870 km^2

Answer:

Area of the given sector=  381.51Km^2

Step-by-step explanation:

In the given figure,

Angle of sector=135°

    radius=18 km

Area of the sector=  \frac{A}{360}\pi  r^2

Where 'A' = Given angle of the sector and r=radius of the sector

       =\frac{135}{360}*\pi*(18)*(18)  \\ \\=\frac{3}{8} *324*\pi

       =0.375*324*3.14

    Area of the given sector=  381.51Km^2

1 and 2 form a linear pair. If the
natka813 [3]

Angles that form a linear pair add up to 180 degrees.

If the measure of angle 1 is 113, then all we must do is subtract:

180-113=67 degrees

And we're done!

Good luck! :)

Hope it helps you!

A car braked with a constant deceleration of 16ft/s2, producing skid marks measuring 200 feet before coming to a stop. How fast
Llana [10]

Answer:the car was traveling at a speed of 80 ft/s when the brakes were first applied.

Step-by-step explanation:

The car braked with a constant deceleration of 16ft/s^2. This is a negative acceleration. Therefore,

a = - 16ft/s^2

While decelerating, the car produced skid marks measuring 200 feet before coming to a stop.

This means that it travelled a distance,

s = 200 feet

We want to determine how fast the car was traveling (in ft/s) when the brakes were first applied. This is the car's initial velocity, u.

Since the car came to a stop, its final velocity, v = 0

Applying Newton's equation of motion,

v^2 = u^2 + 2as

0 = u^2 - 2 × 16 × 200

u^2 = 6400

u = √6400

u = 80 ft/s

Jack's last six scores are 75,78,83,80,79,84. If he scores a 90 on the next test, by how much will his mean test score increase?
kondaur [170]

Answer:

1.46

Step-by-step explanation:

First find the the mean score before he made a 90.

\frac{75+78+83+80+79+84}{6} = 79.83

Now add the score of 90 and calculate.

\frac{75+78+83+80+79+84+ 90}{7} = 81.29

Subtract the two scores.

81.29-79.83 = 1.46

His mean test score increased by 1.46.
