The number of miles to walk in two hours 6 miles why? easy Becuase if you know there is 60 minutes in a hour so multiply 60 times 2 becuase the 2 means the hours and the 60 how many minutes in a hour okay you know that. Now divide 120 by 20 which equals 6 there you get answer! the 20 means the minute per mile and the 120 the 2 hours hope I help good luck!
Answer:
You can do this by dividing the radicand by the square number , and multiplying the radical by the root of that number.
e.g.
Very interesting wording but from what I gathered, scaling down by a factor of 1/10 would be 64- 6.4(1/10 of 64) so your final answer would be 57.6
Hope this explanation helps ;)
Answer:
Length of rectangular strip = 12
area of rectangular strip = 2*12 = 24
Area of square = x^2 = 12^2 = 144
Step-by-step explanation:
Area of square x^2
area of rectangle is given by length * width
Length of rectangular strip = x
width of rectangular strip = 2
area of rectangular strip = length * width = 2*x = 2x
Area of square piece of paper when rectangular strip is taken away from it
= Area of square - area of rectangular strip
=
It is given that Area of square piece of paper when rectangular strip is taken away from it is 120 square units.
Thus,
Thus,
either x+10 = 0 or x -12= 0
x = -10 or x = 12
but length cannot be negative hence neglecting x = -10
hence value of x is 12.
Hence,
Length of rectangular strip = 12
area of rectangular strip = 2*12 = 24
Area of square = x^2 = 12^2 = 144
