I am doing a math project for Geometry. I am using Singapore Flyer as example for a circle. This is the information I know so fa

r: diameter = 150m (radius=75), Circumference = 471 m, Area = 17,662.50 m, there are 28 capsules/compartments where people go into ride it. I now need to get the measure of the center angle and the arc length. I am pretty sure I need to use formula 2(pi)(r)(x/360) to solve for x = central angle. If I input what I know (radius = 75) 2(3.14)(75)(x/360) = 471(x/360) = 471x/360 = x = 1.3083 repeating. Is this right or do I need to use a different formula? Thank you all for your help.

The figure below shows a shaded rectangular region inside a large rectangle: (pic)
mariarad [96]

Answer:

D


Step-by-step explanation:

Probability of falling NOT in the shaded region is "area of white region" <em>divided by</em> "area of whole rectangle (big one)".


<u>Area of whole rectangle:</u>

Area of rectangle = length * width = 10 * 5 = 50


<u>Area of White Region:</u>

First, area of shaded region = length * width = 4 * 2 = 8

Now,

Area of white region = area of whole rectangle - area of shaded rectangle

Area of white region = 50 - 8 = 42


Hence, probability is \frac{42}{50}=0.84

0.84 = 84%

Answer choice D is right.

A ferry is travelling at a constant speed back to the dock, as shown in the graph. Which
mario62 [17]

Answer:

c. y = -35*x + 105

Step-by-step explanation:

Lo que demos hacer es calcular los puntos cuando x = 0 y cuando x = 3, es decir el inicio y el fin del recorrido.

Cuando x es igual 0, y = 105, por lo tanto, la función sería:

y = A*x + 105

Cuando x = 3, y = 0, por lo tanto:

0 =  3*A +  105

resolvemos para A:

3*A =  -105

A = -105/3

A =  -35

Por lo tanto la función es:

y = -35*x + 105

es decir, la opción c.
