Inscribed Angle Theorem
If an angle is inscribed in a circle, then the measure of the angle equals one half the measure of its intercepted arc.
so the intercepted arc is TWICE the measure of an angle inscribed in a circle
1. A central angle is an angle with endpoints located on a circle's circumference and vertex located at the circle's center. A central angle in a circle determines an arc.
2. An inscribed angle is an angle formed by three points on the circle's circumference.
Angle at the Center Theorem: An inscribed angle is half of the central angle (if they determine the same arc).
In your case angles:
1. ∠QSR is insribed (determines the arc QR);
2. ∠QTR is central (determines the arc QR).
Then by Angle at the Center Theorem, m∠QTR=2m∠QSR=2·52°=104°. Arc QR has the same measure as central angle QSR.

Expand (5x – 3y + 2) using identity.
Answers
Answer:
[tex](5x - 3y + 2)^2=25x^2+9y^2+4-30xy-12y+20x[/tex]
Step-by-step explanation:
We need to expand (5x – 3y + 2)² using identity.
Using identity,
[tex](a+b+c)^2=a^2+b^2+c^2+2ab+2bc+2ac[/tex]
We have, a = 5x, b = -3y and c = 2
So,
[tex](5x - 3y + 2)^2=(5x)^2+(-3y)^2+2^2+2(5x)(-3y)+2(-3y)(2)+2(2)(5x)\\\\=25x^2+9y^2+4-30xy-12y+20x[/tex]
So, the required answer is [tex]25x^2+9y^2+4-30xy-12y+20x[/tex].

108
Explanation:
In any geometric series, we need two pieces of information to find its sum to the
n
-th term, and thus the sum to infinity.
Firstly, we need the first term,
a
. This is obviously
36
in this expression.
Secondly, we need the common ratio,
r
,. We find this by taking 24/36 =2/3
Thus a =36 and r =2/3 . also note that
(R) =2/3 <1
We then apply the formula for sum of geometric series to the
n -th term when (r) <1 : Sn =a(1 -rn ) / 1-r = 36 ( 1 - (2/3 ) n) / 1 -(2/3)
=108 (1 -(2/3) n)
The sum to infinity s ♾ is defined to be the limit of sn as n - ♾
N- ♾,(2/3) n -0.sn -108 -0 =108
S ♾ =108

The median bisects the side opposite the vertex, so ...
P is the midpoint of AC
Since AC = 25, the length of half that segment is PC = 12.5. Of course, that is the sum of segments PR and RC:
PR + RC + PC

(05.06 LC) A person drives her own personal vehicle to work two days of the week. Her commute to and from work is 42 miles a day, and her car averages 28 miles per gallon? How much gasoline is the person conserving a day if she takes the train instead? Group of answer choices 1.5 gallons per day 3.0 gallons per day 4.5 gallons per day 5.5 gallons per day
Answers
Answer:
1.5 gallon per day
Step-by-step explanation:
As given,
Daily miles = 42
Average gasoline used = 28 mil/gallon
Daily use of gasoline = [tex]\frac{Daily mile}{Average gasoline}[/tex]
= [tex]\frac{42}{28}[/tex] = 1.5 gallon /day
∴ we get
she conserve gasoline a day = 1.5 gallon per day
A city cat show is underway. Complete with purring, meowing, and an occasional hiss. There are three times as many orange cats as black and white cats, two times as many black and white cats as grey cats, three fewer gray cats then white cats, three times as many white cats as calico cats, and five white cats. How many of each kind of cat is in the show? How many in all?
Answers
Answer:
Step-by-step explanation:
There are three times as many orange cats as black and white cats,
o = 3(b + w)
two times as many black and white cats as grey cats,
b + w = 2g
three fewer gray cats than white cats,
g = w - 3
three times as many white cats as calico cats,
w = 3L
and five white cats
w = 5
There is a problem with this.
There are 5 white cats.
There are 3 times as many white cats as calico cats.
That means there are 5/3 calico cats.
How can the number of a certain type f cats be a non-whole number?
It seems that the number of white cats must be a multiple of 3, but 5 is not.

Taylor is decorating for a party. She cuts 5 equal-length streamers from a strip of yellow paper that is 9 feet long. How long is each streamer in fraction form?
Answers
Answer: 1 4/5 feet
Step-by-step explanation:
Length of the strip of yellow paper = 9 feet.
Number of streamers that were cut = 5
Length of each streamer will then be:
= Length of the strip of yellow paper = 9 feet / Number of streamers that were cut
= 9 feet / 5
