the lenght of the floor is 32 m longer than its width and there is greater than 200 square meters. you will cover the floor comp
letely with tiles. what will be the possible dimension of the floor?
1 answer:
Let’s assume the width of the floor is x and the area is a
To figure out the dimensions we need to figure out the value of the variable (x)
This means that the length is xm+32m (the m is for metres) and that the area is a>200m2
Because it says what is the possible dimensions let make the area 201m2
The formula for the area of a rectangle is length times width so the equation we use to figure out the value of x
201=x+x+32
So let’s collect like terms and solve from there
201=2x+32
201-32=2x+32-32
169=2x
169/2=2x/2
84.5=x
Now that we know the value of x is 84.5 we can figure out the length is 116.5m and the width is 84.5m
Therefore the dimensions of the floor is 116.5m by 84.5m

Answer:
428.7 mm²
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 17² × 
= 289π ×
= 
≈ 428.7 mm²
Answer:
m = y2 - y1 / 2 - 3
Step-by-step explanation:
I believe it is asking you to plug in the numbers into the equation.
Answer:
y=8
Step-by-step explanation:
Point slope is y2-y1 over x2-x1
So its 8-(-6) over 8-8 which equals 14/0 which means the equation of the line is y=8
This is a horizontal line on 8 on the y axis
Answer:
False
Step-by-step explanation:
x
The opposite of x is -x
x* -x = -x^2

Answer:
1 1/6
Step-by-step explanation:
4 2/3 ÷ 4
Convert the mixed number into an improper fraction:
4 2/3 = 14/3
14/3 ÷ 4
14/3 ÷ 4/1
Use cdf (copy dot flip)
14/3 × 1/4
14 × 1 / 3 × 4
14/12
Convert improper fraction into a mixed number:
14/12 = 1 2/12
1 1/6
