Explanation:
Using the concept of supplementary angles, we can use the angle given to find for x.
Supplementary angles refer to angles that add up to a 180 degree angle/straight line. If we were to put the angle for x and 45 together we would get an angle of 180. So, to find x we can use 180-45, which equals 135.

37 The diameter of circle X is 15 centimeters. The diameter of circle Y is 20 centimeters.
Which measurement is closest to the difference between the circumference of circle X and the
circumference of circle Y in centimeters?
A 15.7 cm
B 7,85 cm
C 137 cm
D 31.4 cm
Answers
Answer:
A
Step-by-step explanation:
this can be done without any calculator, which I did and explain below :
the circumference of a circle is always
2×pi×r
with r being the radius, which is always half of the diameter.
so, the circle X circumference is
pi×15
circle Y
pi×20
the difference is
20×pi - 15×pi = 5×pi
5×pi is half of 10×pi, which would be 10×3.1415... = 31.415...
half of that is about 15.7.
so, A is the correct answer

The composition of similarity transformations that maps Triangle LMN to TriangleL'M'N is a dilation with a scale factor less than 1 and then a reflection. Opion A. This is further explained below.
Which composition of similarity transformations maps TriangleLMN to TriangleL'M'N'?Generally, In the case of a reflection across the y-axis, the y-coordinate of a point stays the same but the x-coordinate is changed into its inverse.
Triangle LMN has the coordinates (2, 1), (1, 1), and (1, 3).
(-4,-4) (-3,-4) (-3,-2).
In conclusion, Assuming that the coordinates (2, 1), (1, 1), and (1, 3) of Triangle LMN. This is the translation 5 units down (x,y-5): Two units to the right (x+2, y-5) of the coordinates (2,-4), (1,-4), and (1,-2): (4, -4), (3, -4), (3, -2)
It is a reflection along the y-axis, with coordinates of (-4,-4) and (-3,-4) (-3,-2)
Therefore, Triangle L'M'N' is the result of the transformation sequence in Option A.

The perimeter of a rectangular piece of paper is 28 inches. The area is 45 square inches. What are the dimensions of the paper?
Answers
The dimensions of the paper are 9 by 5 inches
How to determine the dimensions?Let x represent the length and y, the width
The given parameters are:
Perimeter, P = 28
Area, A = 45
So, we have
P = 2(x + y) = 28
A = xy = 45
Rewrite as:
2(x + y) = 28
xy = 45
By trial by error, we have:
x = 9 and y = 5
This can be proved as follows:
2(9 + 5) = 28--- true
9 * 5 = 45 --- true
Hence, the dimensions of the paper are 9 by 5 inches

the highest of three cylinders are 3 cm 9 cm and 5 cm if the cylinder has a capacity of 725 calculate the capacitance of the other cylinders
Answers
The capacitance of the other cylinders are 2174. 94cm³ and 1208. 30cm³.
How to find the capacitanceCapacity of a cylinder is seen as its volume
Volume of a cylinder = πr²h
The heights of the cylinders are
a. 3cm
b. 9cm
c. 5cm
Let's find the radius
Capacity = 3. 142 × r² × 3
725 = 3. 142 × r² × 3
r² = [tex]\frac{725}{3. 142 * 3}[/tex]
r² = [tex]\frac{725}{9. 426}[/tex]
r² = 76. 91
r = √76. 91
r = 8. 77cm
Radius of the cylinders = 8. 77cm
For cylinder with height of 9cm
Capacitance = πr²h
Capacitance = 3. 142 × 8. 77 × 8. 77 × 9
Capacitance = 2174. 94 cm³
For cylinder with height of 5cm
Capacitance = 3. 142 × 8. 77 × 8. 77 × 5
Capacitance = 1208. 30 cm³
Thus, the capacitance of the other cylinders are 2174. 94cm³ and 1208. 30cm³.

a sweet factory produces 5 different chocolate bars. the different flavors are always produced in the same proportions, for every 4 coconut flavored bars 5 honeycomb 6 orange and 4 strawberry
what is the total number of chocolate bars if there are:
a) 280 orange flavored bars?
b) 960 coconut flavored bars?
c) 79 coffee flavored bars?
Answers
a. There are 933 chocolate bars
b. There are 1200 chocolate bars
c. There are 1580 chocolate bars
How to calculate the number of chocolate barsSince there are 5 different flavors,
let
x = orange flavored bars, y = coconut flavored bars, z = coffee flavored bars, a = strawberry flavored bars and b = honeycomb flavored bars and X = total number of barsSince the different flavors are always produced in the same proportions, for every 4 coconut flavored bars 5 honeycomb 6 orange 1 coffee and 4 strawberry
So, the ratio of their proportions are x:y:z:a:b = 6:4:2:1:5
So, the total ratio is T = 6 + 4 + 1 + 4 + 5 = 20
a. What is the total number of chocolate bars if there are 280 orange flavored bars?Since we have 6 orange flavored bars, the ratio of orange flavored bars to total is 6/20
So, the amount of orange flavored bars is x = 6/20 × X
Making X subject of the formula, we have
X = 20x/6
So, if there are 280 orange bars, there will be
X = 20x/6
X = 20 × 280/6
X = 5600/6
X = 933.33
X ≅ 933 chocolate bars
So, there are 933 chocolate bars
b. What is the total number of chocolate bars if there are 960 coconut flavored bars?Since we have 4 coconut flavored bars, the ratio of coconut flavored bars to total is 4/20
So, the amount of coconut flavored bars is y = 4/20 × X
Making X subject of the formula, we have
X = 20y/4
So, if there are 960 coconut flavored bars, there will be
X = 20y/6
X = 20 × 960/4
X = 5 × 240
X = 1200 chocolate bars
So, there are 1200 chocolate bars
c. What is the total number of chocolate bars if there are 79 coffee flavored bars?Since we have 1 coffee flavored bars, the ratio of coffee flavored bars to total is 1/20
So, the amount of coconut flavored bars is z = 1/20 × X
Making X subject of the formula, we have
X = 20z
So, if there are 79 coffee flavored bars, there will be
X = 20z
X = 20 × 79
X = 1580 chocolate bars
So, there are 1580 chocolate bars

When David was asked how old he was, he said " I'm three times younger than my dad, but twice as old as Rebecca. " Then little Rebecca ran up to him and declared "i am 30 years younger than my dad". How old is David
Answers
Using a system of equations, it is found that David is 12 years old.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
The variables are given as follows:
Variable x: David's age.Variable y: Dad's age.Variable z: Rebecca's age.David is three times younger than the dad and twice as old as Rebecca, then:
x = y/3 -> y = 3x.x = 2z.Rebecca is 30 years younger than the dad, hence:
z = y - 30.
Then, since x = 2z and z = y - 30 and y = 3x, we solve for x to find David's age.
x = 2(y - 30)
x = 2(3x - 30)
x = 6x - 60
5x = 60
x = 60/5
x = 12.
David is 12 years old.
