Answer:
The dimensions of rectangle a are 6x4 and dimensions of rectangle b are 6x2.
Step-by-step explanation:
We are given a square with area 36 squared cm. Therefore, dimension of the square will be 6 cm.
The square is cut into two rectangles with areas in the ratio 2:1.
Let the dimensions of the rectangles be 6*a and 6*b. Therefore, we can set up the ratio of areas as:
Moreover, we can set the combined area of rectangles equal to the area of square to form another equation:
Using substitution method, we can solve for 'a' and 'b' as shown below:
And
Therefore, dimensions of the two rectangles are 6x4 and 6x2, respectively.
This is a good one!
So we know that a triangle's angles must add up to 180 degrees. Therefore, we can say that:
(3x - 3) + (5x + 3) + (4x) = 180.
This can be rewritten as 12x = 180.
Divide each side by 12 to get x alone, you get:
x = 15
Time to plug n' chug.
4x = 60, 3x - 3 = 42, 5x + 3 = 78
Boom!
So percent is x/100 because percent means parts out of 100
600/6=100 so
84/600=what percent=x/100
84/600 divided by 6/6=14/100
the answer is 14%
Answer:
Step-by-step explanation:

Answer:
The smallest whole number length is 12
Step-by-step explanation:
The sum of any two sides of any triangle must be greater than the length of the third side.
In this case, the two smallest sides of the triangle must be greater than the third side to satisfy the statement above.
Let "x" = the length of the third side.
Our two smaller sides are "x" and "4", and their sum must be greater than 15.
x + 4 > 15
x > 15 - 4
x > 11
