Answer:

The length of arc EF is 11.3

Step-by-step explanation:

Since both angles are congruent, we can say that they are equal in value

Mathematically, the length of an arc can be calculated using the formula;

L = theta/360 * 2 * pi * r

where theta is the angle subtended and r is the radius of the circle

So for circle A, we have;

18.08 = theta/360 * 2 * π * 8

theta = (360 * 18.08)/16π

Theta = 406.8/π

Now we shall substitute this angle in the second circle to get its length

L = 406.8/π * 1/360 * 2 * π * 5

L = 406.8/36 = 11.3

An object is 3.6 m from the pinhole. Its image is 4.2 cm from the opposite side of the pinhole. The height of the image is 0.8 c
madreJ [45]

Answer:

Height of the object is 68.6 cm.

Step-by-step explanation:

The height of the object can be determined by:

\frac{object distance from pinhole}{image distance from pinhole} = \frac{object height}{image height}

From the given question;

object distance from pinhole = 3.6 m = 360 cm

image distance from pinhole = 4.2 cm

height of image = 0.8 cm

So that;

\frac{360}{4.2} = \frac{object height}{0.8}

⇒ object height = \frac{360*0.8}{4.2}

                           = \frac{288}{4.2}

                           = 68.571

object height = 68.6 cm

Thus, the height of the object is 68.6 cm.

The odds in favor of a spinner landing on blue is 2:7. What is the probability of a spinner NOT landing on blue?
Doss [256]

Answer:

7/9

Step-by-step explanation:

P(blue) = 2:7

This means there are 2 blue parts for every 7 nonblue parts. So 9 parts total! 2:7, then, should be thought of as 2/9.

P(not blue) = 1 - 2/9

                  = 7/9

Think about it: there must be a total probability of 1, so the probability of <em>not</em> getting blue must be 7/9.
