Answer:
Step-by-step explanation:
you first mulitply the denomenater by the whole number and add the numerator.
Than you flip the second fraction and muliply the two fractions together.
And then you simplify the fraction if you can.
We don't need the length AND width of the square. One number
will be enough for an answer, because all sides of a square have
the same length. Let's call that number ' M ' (for 'mystery number').
-- The area of the square is M² .
The question says that ...
-- The length of the rectangle is 2M .
-- The width of the rectangle is (M - 3) .
Therefore ...
-- The area of the rectangle is (2M)(M - 3) = 2M² - 6M .
The question also says that ...
-- The areas of the square and the rectangle are equal:
So 2M² - 6M = M²
Subtract M² from each side: M² - 6M = 0
Divide each side by M : M - 6 = 0
Add 6 to each side : M = 6 .
Check:
Assume ... Side of the square = 6
Then ...
Area of the square = 6² = 36 .
Length of the rectangle = (6 x 2) = 12
Width of the rectangle = (6 - 3) = 3
Area of the rectangle = (12 x 3) = 36
36 = 36 yay!
Answer:
12.5 units or 12 1/2 units
Step-by-step explanation:
From the question, it uses 7.5 units in 3 hours.
In one hour it will use; 7.5/3 = 2.5 units
If 2.5 units is used in 1 hour
In 5 hours; 5 × 2.5 units will be used. This gives us 12.5 units or 12 1/2 units.
Answer:
here we have to divide the number of words per hour to the number of minutes per hour.
Step-by-step explanation:
5400÷60
=90.
therefore in a minute she types 90 words.
