Circle Q is shown. Secant L N and tangent P N intersect at point N outside of the circle. Secant L N intersects the circle at po

int M. Arc M P is y, arc L P is x, and arc M L is z.
Which equation is correct regarding the measure of ∠MNP?

m∠MNP = One-half(x – y)
m∠MNP = One-half(x + y)
m∠MNP = One-half(z + y)
m∠MNP = One-half(z – y)

Answer: FIRST OPTION.

Step-by-step explanation:

By definition, the "Angle formed by a Tangent and a Secant" is:

Angle\ formed\ by\ Tangent\ and\ Secant=\frac{1}{2}({Difference\ of\ Intercepted\ Arcs)

In this case you can identify in the figure that the Intercepted Arcs are:

 LP=x and PM=y

And the Angle formed by the tangent and the secant is:

\angle MNP

Therefore, the following equation can be used to calculate the measure of the angle ∠MNP:

m\angle MNP=\frac{1}{2}(LP-PM)\\\\m\angle MNP=\frac{1}{2}(x-y)

This matches with the First option.

Tanya made 75 flyers for five volunteers in her club to hang up around her school she gave 15 flyers to the first volunteer 22 f
AysviL [449]

Answer:

The remaining volunteers would get 11 flyers each.

Step-by-step explanation:

Given:

Total number of flyers = 75

Total number of volunteers = 5

Number of flyers for 1 volunteer = 15 flyers.

Number of flyers to 2nd volunteer = 22 flyers.

number of flyers to 3 volunteer = 16 flyers.

We need to find the remaining number of which are equally distributed in remaining number of volunteers.

Solution:

First we will find the number of flyers already distributed.

number of flyers already distributed is equal to sum of Number of flyers for 1 volunteer, Number of flyers for 2 volunteer and Number of flyers for 3 volunteer.

framing in equation form;

number of flyers already distributed = 15+22+16 = 53\ flyers

Number f flyers remaining is equal to Total number of flyers minus number of flyers already distributed.

Number of flyers remaining = 75-53= 22\ flyers

Number of volunteers remaining  =2

Now we will find number of flyers remaining each volunteers would get.

number of flyers remaining each volunteers would get is equal to Number of flyers remaining divided by Number of volunteers remaining.

framing in equation form we get;

number of flyers remaining each volunteers would get = \frac{22}{2}=11\ flyers

Hence the remaining volunteers would get 11 flyers each.
