Answer:
The value of n is 
Step-by-step explanation:
we know that
1 m=100 cm
step 1
Convert 2.5 m to cm
2.5 m=2.5*100=250 cm
step 2
Find the ratio

Divide by 25 both numerator and denominator

therefore
The value of n is 
.45 is 45/100 (simplify) 9/20
1/2 is already simplest form of fraction.
Answer:
y = 12/5x + 22
Step-by-step explanation:
First, let's find the slope of the AB line.
y2 - y1 / x2 - x1
3 - 8 / 2 - (-10)
-5 / 12
= -5/12
When a line is perpendicular to something, the slope becomes the opposite.
y = 12/5x + b
10 = 12/5(-5) + b
10 = -12 + b
22 = b
Answer:
For y=37, x= -4
Step-by-step explanation:
We have to find the value of x, when y=37 is the given value for the given equation

Putting the value of y=37 in the equation to find the 'x'


So, for the value of y=37, the value of 
Answer: 118 feet
Step-by-step explanation:
For a rectangular shape: Area = W × L
450 = 9 × L
450 ÷ 9
L = 50
Perimeter of a rectangular shape = 2L + 2W
Perimeter = (2 × 50) + (2 × 9)
= 100 + 18 = 118 feet
