4/5 is the answer.
The formula is y=mx+b, where m is the slope
Answer:
140.63 is the correct answer
Step-by-step explanation:
Since we have given that
Length of 1 square tile = 11.25 inches
Number of tiles to cover the length of floor = 12.5
We need to find the length of the floor.
So, Length of floor is given by
Length of 1 square tile × Number of tiles
Hence, the length of floor is 140.625 inches.
Answer:
533.33 ft/min
Step-by-step explanation:
We are given that
x=3 feet
y=4 feet
Height of person,h=6 feet

Triangle ABC and A'B'C are similar because all right triangles are similar
By using similarity property








Differentiate w.r.t t



Hence, If the person is 6 feet tall and walks away from the lamp post at a speed of 400 feet per minute then his shadow moving at the rate 533.33 ft/min
Plugging the values if x and y the last option is correct
3x-y=4
Ok so important numbers 42 ft, 2cm, 3 ft and lets take height as x
if 2cm=3ft than x cm= 42 ft
2 = 3
-------
x= 42
cross multiply divide
(42)2/3
84/3
