Answer:
5:2
Step-by-step explanation:
In centimetres
convert 2 m to cm which will be 200 cm
then simplify 200 cm:80 cm --> 5:2
(we cancelled out the zero --> 20:8 then divide 20/2= 10 and 8/2= 4
again the same --> 10/2= 5 and 4/2= 2.
5 and 2 are prime numbers which have no other factor except for 1 and themselves so it cannot be simplified further.
Therefore your answer is 5:2
In metres
convert 80 cm to m which will be 0.8 m
the same steps: simplify 2:0.8
to remove the decimal move the decimal place one to the right --> 8
so you also have to move the decimal place to the right for the numerator: 20
20/8 = 5/2
Classrooms on one side of the drama building are all numbered with consecutive even integers. If the first room, the room with the smallest classroom number, on this side of the building is numbered y, write an expression in y for the sum of the
first four classroom numbers in a row. Then simplify this expression
The sum of the first four classroom numbers in a row is
Consecutive odd numbers are two apart (5, 7, 9, 11...). So given an odd integer, we can add 2 to get the next odd integer.
If the first odd integer is y, then the first 4 odd integers are
y
y+2
y+4
y+6
These add up to 4y+12
The sum of the first four classroom numbers in a row is 4y+12.
It is required to find the sum of the first four classroom numbers in a row.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
Since the smallest classroom number on the side of the building is numbered y and each consecutive even integers is separated by a difference of 2.
∴
y is the first class room.
y + 2 is the second class room.
y + 4 is the third class room.
y + 6 is the third class room.
The sum of the five consecutive class rooms are given as:
y + (y + 2) + (y+ 4) + (y + 6)
collecting alike terms we get
= y + y+ y+ y + 2 + 4 + 6
= 4y + 12
Therefore, the sum of the first four classroom numbers in a row is 4y+12.

Personal behavior is the only factor that determines if a person becomes ill.
The answer is False. Personal behavior is not the only factor that determines an individual’s illness or sickness. There are other factors which determine an individual’s sickness and dysfunction. There are reasons like obesity which leads to several diseases.
This is false because genetics and environmental factors may also come into play. So there are many factors to be considered if a person becomes ill.

How do u write “the quotient of c and 2 “ as a variable expression?
The variable expression c/2 represents the quotient of c and 2, where c can be any numerical value or variable.
To write "the quotient of c and 2" as a variable expression, we can use the division operation to represent the quotient.
The variable expression would be:
c/2
c represents the variable, and dividing c by 2 gives us the quotient of c and 2.
Let's break it down further to understand this expression in more detail:
The term "quotient" refers to the result of dividing one quantity by another.
We are interested in the quotient of c and 2.
The variable c represents an unknown value or a variable that can take on different numerical values.
The number 2 is the divisor or the quantity by which we divide c to find the quotient.
By using the division operator (/), we can create a variable expression that represents the quotient of c and 2.
We evaluate this expression by substituting specific values for c, we will obtain the result of dividing c by 2.
If we let c = 10, then the expression c/2 would evaluate to 10/2, which equals 5.
If c = 6, the expression c/2 would evaluate to 6/2, which equals 3.

If transversal t cuts parallel lines r and s, then the angles ∠3, ∠5 and ∠6 are congruent to ∠2.
What is Coordinate System?Coordinate systems are used to describe the (linear) position of points and the angular position of axes, planes, and rigid bodies.
A transversal is a line, ray, or line segment that intersects other lines, rays, or line segments on a plane at different intersecting points.
Congruent angles are two or more angles that are identical to each other.
The angle ∠2 measure is equal to ∠3.
∠2 measure is equal to ∠6.
∠6 measure is equal to ∠5.
The measures ∠3, ∠5 and ∠6 are equal to the measure of ∠2.
∠3, ∠5 and ∠6 are congruent to ∠2
Hence, if transversal t cuts parallel lines r and s, then the angles ∠3, ∠5 and ∠6 are congruent to ∠2.

The perimeter of a rectangular playing field is 280 feet. The length of the field is 20 feet more than the width. What are the dimensions of the playing field? (You need to find the length and the width.)
Answer:
L =80
w=60
Step-by-step explanation:
P =280
L =w +20
=>L +w=280 :2 =140
w+20+w=140
2w=140 - 20
2w =120
w=120 :2 =60
L=60 +20 =80
P =2L +2w
P =2 ×80 +2 ×60
P=160 +120
P=280
Answer:
L = 80 , w=60
Step-by-step explanation:
l= w+20
perimeter: l+w+l+w=280
Plug in the value of L in place of L
(w+20)+w+(w+20)+w=280
Combine Like terms
and then separate the variables and knowns by subracting 40 from both sides
4w+40=280
-40 -40
Divide by 4 from both sides so (W) would be alone
4w=240
÷4 ÷4
You solved half the question now
w = 60
Remember the L at the top
we now know the value of W
so
L=(60)+20
L=80
just to be sure
80+80+60+60=280
