Given 2 congruent chords in the circle, then they are equidistant from the centre and perpendicular
There is a right triangle formed by legs 15 and 8, with radius r being the hypotenuse.
Using Pythagoras' identity in this right angle
r² = 15² + 8² = 225 + 64 = 289 ( take the square root of both sides )
r = [tex]\sqrt{289}[/tex] = 17
Find the value of x.
Answer:
x = 2
Step-by-step explanation:
the radius is 5
both triangles are congruent because of the SAS theorem.
x = 2 because corresponding parts of congruent tringles are congruent.
Belinda is a wedding planner who wants to help couples determine how many people to invite to their wedding. She collects data on hundreds of weddings and finds that you can predict the number of guests based on the total number of immediate family members (parents, siblings, children) of the couple. The equation for doing so is: (Guests)-hat = 38.28 + 15.47 (Family Members)
What is the best prediction for the number of guests a couple with a total of 12 family members? (Do not round your answer)

In the accompanying diagram, parallelogram ABCD has
vertices A(2, 1), B(8,1), C(11,5), and D(5,5). What is the
area of parallelogram ABCD?
Answer:
The area of the paralellogram is 24 square units.
Step-by-step explanation:
Geometrically speaking, the area of the parallelogram has an equation equivalent to the area formula for a rectangle, that is:
[tex]A = b\cdot h[/tex] (1)
Where:
[tex]A[/tex] - Area.
[tex]b[/tex] - Base.
[tex]h[/tex] - Height.
The base and height of the parallelogram are, respectively:
Base
[tex]b = 8-2[/tex]
[tex]b = 6[/tex]
Height
[tex]h = 5-1[/tex]
[tex]h = 4[/tex]
Then, the area of the parallelogram is:
[tex]A = (6)\cdot (4)[/tex]
[tex]A = 24[/tex]
The area of the paralellogram is 24 square units.

The square root of 125 is between
Answer:
[tex] \sqrt{125 } \\ = 11.18[/tex]
It is in between 0 to 12.
Answer:
√125 must be between 11 and 12.
Step-by-step explanation:
Identify perfect squares in the neighborhood of 125:
121 = 11^2 or √121 = 11
144 = 12^2 √144 = 12
√125 must therefore be between 11 and 12.
Find the solution to the following system using substitution or elimination:
Answer:
B) (3,1)
Step-by-step explanation:
y = -2x + 7
y = 3x - 8
3x - 8 = -2x + 7
combine like terms:
5x = 15
divide both sides of the equation by 5:
x = 3
y = 3(3) - 8 = 1

The explicit formula for a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = - 1 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{-5}{-1}[/tex] = 5 , then
[tex]a_{n}[/tex] = - [tex]5^{n-1}[/tex]
13
Using the explicit formula for a geometric sequence
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = - 48 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{96}{-48}[/tex] = - 2 , then
a₁₀ = - 48 × [tex](-2)^{9}[/tex] = - 48 × - 512 = 24576
Question 2 (1 point)
What is the length of a day-night cycle? Is it the same everywhere on Earth?
12 hours - yes; because the sun rises and sets in the exact same place every day
relative to Earth.
12 hours - no; because depending on where you are on Earth, you have a
different amount of sunlight.
24 hours - yes; because the sun rises and sets in the exact same place every day
relative to Earth
24 hours - no; because depending on where you are on Earth, you have a
different amount of sunlight.
Answer: 24 hours - no; because depending on where you are on Earth, you have a different amount of sunlight.
Step-by-step explanation:
The day-night cycle is a complete day or a complete rotation of the earth around its axis. This takes 24 hours which is why 24 hours is the length of a full day.
People around the world however, do not get the same amount of sunlight or darkness and this is because of where they are on Earth. Due to the way the planet is tilted on its axis, some areas see sunlight more than other in a period and others see more darkness.

guys what does integer mean in mathematicians , plss help i kind of forgot✌
Answer:
Integer is a whole number; a number that is not a fraction.
Step-by-step explanation:
1) (x - 2)/(x - 3) + (3x - 11)/(x - 4) = (4x + 13)/(x + 1)
Step-by-step explanation:
or,(x-2)(x-4)+(3x-11)(x-3)/(x-3)(x-4)=(4x+13)/(x+1)
or,x^2-4x-2x+8+3x^2-9x-11x+33/x^2-4x-3x+12=(4x+13)/(x+1)
or,4x^2-4x-2x-9x-11x+8+33/x^2-7x+12=(4x+13)/(x+1)
or,4x^2-26x+41/x^2-7x+12=(4x+13)/(x+1)
or, (x+1)(4x^2-26x+41)=(4x+13)(x^2-7x+12)
or,4x^3-26x^2+41x+4x^2-26x+41=4x^3-28x^2+48x+13x^2-91x+156
or,-26x^2+4x^2+28x^2-13x^2+41x-26x-48x+91x=156-41
or,-7x^2+58x=115
or,-7x^2+58x-115=0
or,-(7x^2-58x+115)=0
or,7x^2-58x+115=0
or,7x^2-(35+23)x+115=0
or,7x^2-35x-23x+115=0
or,7x (x-5)-23 (x-5)=0
or, (x-5)(7x-23)=0
Either, Or,
(x-5)=0 (7x-23)=0
or,x=0+5 or,7x=23
:x=5 :x=23/7
Hence,x=5 or 23/7

What is the correct value of x
Answer:
45°Step-by-step explanation:
The triangle is right isosceles.
It is right as the side is the diameter of the circle.
It is isosceles as two sides marked as equal.
Acute angles are same and equal to:
90°/2 = 45°Correct option is 45°
Answer:
<M=90°[inscribed angle on diameter is 90°]
<N=<L=[base angle of isosceles triangle]
now
<M+<l+<N=180°[sum of interior angle of traingle]
[2x-5]×2=180-90
4x-10=90
x=100/4=25
x=25

solve for the length of KM.
Answer:
KM = 29Step-by-step explanation:
Use Intersecting chords theorem and find x:
JU * LU = MU * KU10*2x = 9(2x + 2)20x = 18x + 182x = 18x = 9Find KM:
KM = 2*9 + 2 + 9 = 29Step-by-step explanation:
➡JU×LU=MU×KU
➡10×2x=9(2x+2)
➡20x=18x+18
➡20x-18x=18
➡2x=18
➡x=18/2
➡x=9
KM=KU+UM
➡KM=9+2(9)+2
➡KM=9+18+2
➡KM=29
A cylinder has a base radius of 14 mm and a volume of 3920π. What is the height of the cylinder?

Renata and ben each have 32 feet of wood for framing their rectangular murals. Renata makes her frame 18 ft high. Ben makes his frame 5 ft high. Whose mural has the greater area? How much greater?
Answer: Renata, [tex]416\ ft^2[/tex]
Step-by-step explanation:
Given
The base of rectangular wood is [tex]b=32\ ft[/tex]
The height of Renata frame is [tex]h_r=18\ ft[/tex]
The height of the ben frame is [tex]h_b=5\ ft[/tex]
The area of the rectangular frame is [tex]A=b\times h[/tex]
The area of Renata frame is [tex]A_r=32\times 18=576\ ft^2[/tex]
The area of the ben frame is [tex]A_b=32\times 5=160\ ft^2[/tex]
Clearly, the area of Renata is more by [tex]576-160=416\ ft^2[/tex]

Answer:
c = 5n
Step-by-step explanation:
y = c
x = n
Points on the graph: (1,5) and (2, 10)
Slope:
m=(y2-y1)/(x2-x1)
m=(10-5)/(2-1)
m= 5
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = 5(x - 1)
y - 5 = 5x - 5
y = 5x
c = 5n

A box containing oranges weighs 60kg. The empty box weighs 7.5kg. If the average weight of an
orange is 75g, how many oranges are there in the box?
Answer: 700 oranges
Step-by-step explanation: mass of box is reduced first.
Mass of oranges is 60 kg -7.5 kg = 52.5 kg
Mass or oranges is divided by mass of one orange 75 g = 0.075 kg.
52.5 kg/0.075 kg= 700
