Answer:

Step-by-step explanation:

You need to find out the circumference of the Ferris wheel

C=d*3.14=185*3.14=580.90 m

What the correct answer do not want the wrong answer please

Crank

Answer:

388.5yd²

Step-by-step explanation:

We have Triangle TUV

In the question, we are given already

Angle U = 32°

Angle T = 38°

Angle V = ???

Side t = 31yd

Side u = ?

Side v = ?

Area of the triangle= ?

Step 1

We find the third angle = Angle V

Sum of angles in a triangle = 180°

Third angle = Angle V = 180° - (32 + 38)°

= 180° - 70°

Angle V = 110°

Step 2

Find the sides u and v

We find these sides using the sine rule

Sine rule or Rule of Sines =

a/ sin A = b/ Sin B

Hence for triangle TUV

t/ sin T = u/ sin U = v/ sin V

We have the following values

Angle T = 38°

Angle U = 32°

Angle V = 110°

We are given side t = 31y

Finding side u

u/ sin U= t/ sin T

u/sin 32 = 31/sin 38

Cross Multiply

sin 32 × 31 = u × sin 38

u = sin 32 × 31/sin 38

u = 26.68268yd

u = 26.68yd

Finding side x

v / sin V= t/ sin T

v/ sin 110 = 31/sin 38

Cross Multiply

sin 110 × 31 = v × sin 38

v = sin 110 × 31/sin 38

v = 47.31573yd

v = 47.32yd

To find the area of triangle TUV

We use heron formula

= √s(s - t) (s - u) (s - v)

Where S = t + u + v/ 2

s = (31 + 26.68 + 47.32)/2

s = 52.5

Area of the triangle = √52.5× (52.5 - 31) × (52.5 - 26.68 ) × (52.5 - 47.32)

Area of the triangle = √150967.6032

Area of the triangle = 388.5454973359yd²

Approximately to the nearest tenth =388.5yd²

There are 10 marbles in a paper bag, 6 of which are red. The rest are blue. You play a game with your friend. If you draw a red

maria [59]

No, because you have 1 more marble than her. While you have 6 marbles in the bag, she has 4; there’s a 3/5 chance that you’ll win, and a 2/5 chance that she’ll win.

Answer:

if it's less than 7.66km use Royal, if more than 7.66 use Queen's

Step-by-step explanation:

To get the answer you can set up mutliple equations

For Queen's Cab Company

2.70 + 0.20x = ?

for Royal Cab Company

1.55 + 0.35x = ?

Since you didn't give a distance which is what will determine which is cheaper we can solve as a set of equations.

2.70 + 0.20x = 1.55 + 0.35x

1.15 = .15x

x = 7.66

So this lets you know that at 7.66 km Royal cab company becomes more expensive due to their pence per km.

So if it's less than 7.66km use Royal, if more use Queen's

Can someone help me find the area and perimeter for This and can you explain the process

Eva8 [605]

Answer:

<em>Area of Figure; 3.24π + 21.6 ( square meters ),</em>

<em>Perimeter of Figure; 3.6π + 12 ( meters )</em>

Step-by-step explanation:

As we can see, this picture consists of half circles and a rectangle. If we were to combine each of these half circles, we would get a whole circle with a radius of 1.8 meters;

Area of Circle; πr^2 = π * ( 1.8 )^2 = 3.24π ( square meters ),

If 1.8 is known to be the radius of this full circle, it would be that the diameter is 1.8 * 2 ⇒ 3.6. Knowing that the diameter is one dimension of a rectangle in the picture, we can assume the area of the rectangle to be;

Area of Rectangle; length * width = 6 * 3.6 = 21.6 ( square meters ),

<em>Area of Figure; 3.24π + 21.6 ( square meters )</em>

Now to determine the circumference of these two half circles / whole circle, let us apply the formula 2πr;

Perimeter of Circle; 2πr = 2π * 1.8 = 3.6π

To find the perimeter of the whole figure, we would take the lengths of two of the sides of the rectangles, in addition to the perimeter of the whole circle;

Perimeter of Whole Figure; 3.6π + 6 * 2 = 3.6π + 12 ( meters ),

<em>Perimeter of Whole Figure; 3.6π + 12 ( meters )</em>
