If two chords in a circle are congruent, then they are the same distance from the center of the circle. Then the correct option is B.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
The central angle is double the angle at the periphery that was subtended by the same chords.
Both the extreme points of the chords are connected to the circle. Then the two triangles are formed whose two sides are the radius of the circle that is congruent to each other. Then the triangle will be an isosceles triangle.
And the chord length is also congruent. Then the triangles are congruent to each other by SSS postulates.
If two chords in a circle are congruent, then they are the same distance from the center of the circle. Then the correct option is B.

A teacher Buys tickets for each of my students to visit a museum each student and $6.50 and she spent a total of $182 how many students tickets did you buy
Answer:
The ticket is bought for 28 students.
Step-by-step explanation:
It is given that the teacher is going to buy museum ticket for each students.
Total money spent = $182
Price of each ticket = $6.50
Let total number of tickets bought = [tex]x[/tex]
We know that to find the total amount of money spent on ticket, we can add price of each ticket (i.e. $6.50) [tex]x[/tex] number of times.
OR
In other words, simply multiply the number of tickets with price of each ticket to find the total money spent.
Total money spent = [tex]x \times 6.50[/tex]
We know that total money spent is $182.
[tex]\Rightarrow x \times 6.50 = 182\\\Rightarrow x = \dfrac{182}{6.50}\\\Rightarrow x = 28[/tex]
The ticket is bought for 28 students

The side of one square is equal to 3m and its diagonal is equal to the side of a second square. Find the diagonal of the second square.
Answer:
6m
Step-by-step explanation:
the side of first square = 3 m
area of first square = 3^2= 9 m^2
let the side of second square = x m
since diagonal of first square = x m as per the question
in a square each angle is 90 degree
therefore by applying pythagorus theorem ,
diagonal ^2 = side^2 + side ^2
diagonal^2 = 3^2+3^2=9+9
DIAGONAL= square root of 18
diagonal= 3[tex]\sqrt{2}[/tex] m = side of second square
therefore in second square ,
one angle is 90 degree , therefore by applying pythagorue theorem
diaqonal^2 = side ^2 + side ^2 = (3[tex]\sqrt{2}[/tex])^2 + ( 3[tex]\sqrt{2}[/tex])^2
diagonal ^2 = 18 + 18
diagonal = square root of 36
therefore diagonal of second square is 6m

Find two positive consecutive odd integers whose products is 99.
Answer:
9,11
Step-by-step explanation:
let the numbers be x, x+2 (since consecutive odd integers have a difference of 2)
therefore;
x(x+2)= 99
x²+2x=99
I usually solve the sum like this,
we need to find the nearest square number ( number smaller than the number on the R.H.S)

81+18=99
99=99
hence, 9 is the solution. therefore the positive odd consecutive integers are
x=9
x+2=9+2= 11

given that cosθ 1/3 and θ is acute, what is tanθ?
Answer:
tanθ=2√2
Step-by-step explanation:
cosθ= 1/3, and θ is acute;
cos²θ=1/9
sin²θ+cos²θ=1
sin²θ=1-cos²θ=1-1/9=8/9
=> sinθ=√(8/9)=2√2 /3
tanθ=sinθ/cosθ
tanθ=(2√2 /3)/(1/3)=2√2
tanθ=2√2
I need help with this math problem.
Answer:
x = 2 , y = 4
Step-by-step explanation:
If a quadrilateral has diagonals which bisect each other, then it is a parallelogram.
From the parallelogram we see:
2x = y
y = 2x
Substitute y = 2x in 2(y) - 2 = 6, gives:
2(2x) - 2 = 6
4x = 6 +2
x =2
Substitute x = 2 in y = 2x, gives:
y = 2(2)
y = 4
So x = 2 , y = 4
1/8(5y+64)=1/4(20+2y)
Answer:
-24
Step-by-step explanation:
1/8(5y+64)=1/4(20+2y)
Multiplying both sides of the equation...
1/8(5y)+1/8(64)=1/4(20)+1/4(2y)
1/8(5y)+(64/8)=(20/4)+(2y/4)
1/8(5y)+8=5+y/2
1/8(5y)+8=5+1/2(y)
Now multiplying through by the least common multiple, which is 8
8×1/8(5y)+8×8=8×5+8×1/2(y)
1×1(5y)+64=40+4×1(y)
Simplifying both sides...
5y+64=40+4(y)
5y+64=40+4y
By grouping like terms...
5y-4y=40-64
1(y)= -24
y= -24

As an estimation we are told 5 miles is 8 km.
Convert 72 km to miles.
Answer:
45 miles
Step-by-step explanation:
5 miles = 8 km
72 km = 9 * 8 km
Since 8 km = 5 miles, replace 8 km with 5 miles
72 km = 9 * 8 km = 9 * 5 miles = 45 miles
Dos hermanos juntaron su dinero para comprar un regalo a su papa entre los dos reunieron 864 que cantidad aporto cada uno si paco dio 5 pesos por cada 7 que dio juan
Answer:
Paco contributed = 360pesos
Juan contributed = 504pesos
Question:
Two brothers gathered their money to buy a gift for their dad. Between them they gathered 864, which amount each contributed if Paco gave 5 pesos for every 7 that Juan gave.
Step-by-step explanation:
Let the common factor between each brother = p
Paco gave = 5×common factor = 5p
Juan gave = 7×common factor = 7p
Total money contributed by both brothers = 864
Total money contributed by both brothers = 5p + 7p
5p + 7p = 864
12p = 864
p = 864/12
p = 72
Paco contributed = 5p = 5×72 = 360pesos
Juan contributed = 7p = 7×72 = 504pesos
The measure of an angle is 159
degrees.
What is the measure of its
supplementary angle?
Answer:
21°
Step-by-step explanation:
Supplementary is defined as two angles whose sum is 180. These angles must therefore be on a straight line cut by a transversal and must be less than 180 by themselves.
If one angle is 159, then we can simply subtract it from 180 to get the other angle.
A more algebraic way is to set up the equation, 159 + x = 180. Subtract 159 from 180 to find x.
The Measure of supplementary angle is 21⁰.
What are supplementary angle?The pair of angles that always add up to 180 degrees are referred to as supplementary angles. The term "supplements of each other" refers to these two angles. The Latin words "Supplere" and "Plere" are the source of the word "supplementary." "Supplere" means "supply," while "Plere" means "fill." Thus, "something when supplied to complete a thing" is the definition of "supplementary."
Given an angle 159⁰
and according to supplementary angles property,
when sum of two angles is 180⁰ are supplementary
∠A + ∠B = 180⁰ (angles are supplementary)
Let the another angle be x
159 + x = 180
x = 180 - 159
x = 21⁰
Hence the supplementary angle is 21⁰.

Find the interquartile range (IQR) of the data in the dot plot below. cavities
Answer:
It is 4 cavities
Step-by-step explanation:
The interquartile range (IQR) of the data in the dot plot is 4
Calculating interquartile rangeFrom the question, we are to determine the interquartile range (IQR) of the data
From the diagram, we can produce the data set
0, 0, 0, 1, 1, 3, 3, 4, 7, 7
Now, we will determine the interquartile range of this data set.
The interquartile range is the difference in value between the upper quartile and lower quartile.
The upper quartile (Q3), is the value under which 75% of data points are found when arranged in increasing order.
The lower quartile (Q1), is the value under which 25% of data points are found when they are arranged in increasing order.
∴ IQR = Q3 - Q1
From the data set
0, 0, 0, 1, 1, 3, 3, 4, 7, 7
Upper quartile (Q3) = 4
and
Lower quartile (Q1) = 0
∴ Interquartile range (IQR) = 4 - 0
IQR = 4
