X=4. First, you do 15/12 and get 1.25. You do this to see what number you have to multiply 12 to, to get 15. Since the sides a proportional it should be the same for the sides with their variables. Then you create an expression that puts the numbers the same place where 15 and 12 were to equal 1.25. You cross multiply, solve and get 4.
To find the area that is shaded red, you find the area of the rectangle and subtract it by the area of the triangle.
Area of a rectangle:
A = l × w [ l = 11 in ; w = 6in ] Plug these numbers into the equation
A = 11 · 6
A = 66 in²
Area of a triangle:
[ b = 4 in ; h = 6 in ] Plug these #s into the equation
A = 12 in²
Area of rectangle - Area of triangle = Area of the shaded region
66 in² - 12 in ² = 54 in²
Your answer is B
A mixed number is written in a form of
, where 'a' is a whole number.
One example of mixed number is
, read as 'three and one quarter'. As decimal fraction,
equals to 3.25
We are given the value of 3.15 and to change this into a mixed number, first note the whole number, which is 3.
We then change the decimal value 0.15 into a fraction and it is
Hence, 3.15 =
