Given that the contaminated region is a square, the area is given by the formula:
Area=length*width
since in a square length=width
the
area=length×length
or
area=width×width
thus given that area=4m^4/144n^4 sq. units let the width be w units
thus
area=w×w=4m^4/144n^4
w²=4m^4/144n^4
solving for w we get:
w=√(4m^4/144n^4 )
w=2m²/12n²
Hence the width,w=2m²/12n²
Answer=9
This question is asking how many times can 4 go into 36. Basically 36/4
36÷4=9
36 is 9 times greater than 4
Mary has 5 2/5 yards of string. Written as an improper fraction, 5 2/5 = 27/5 yards of string.
The friend was given 2/3 of the string. The friend received 2/3 * 27/5 = 18/5 yards which is the same as 3 3/5 yards and also 3.6 yards.
After Mary gave the friend the string, Mary had 27/5 - 18/5 = 9/5 yards left.
9/5 yards is the same as 1 4/5 yard and also 1.8 yards.
Answer:
-5, 9, - 1/3, 3
Step-by-step explanation:
a.) (-5, 28) ; (-4, 23)
(23 - 28) / (-4 - (-5))
-5 / 1
= - 5
b.) (-3, - 27) ; (1, 9)
(9 - (-27)) / (1 - (-3))
(9 + 27) / (1 + 3)
36 / 4
= 9
C.)
(1 - 0) / (0 - 3)
1 /-3
-1/3
D.) (-5, - 7) ; (-4, - 4)
(-4 - (-7)) / (-4 - (-5))
(-4 + 7) / (-4 + 5)
3 / 1
