30/75 = 12/x
30*x=75*12
30x=900/:30
x=30
Answer:
See explanation below
Step-by-step explanation:
If x is even, then we know that x = 2k for a k ≥1
If y is odd, then we know that y = 2j -1 for a j≥1
Therefore, x + y can be written similarly as:


And clearly, 2(k + j) -1 is odd.
Therefore, the sum x + y is an odd number.
Answer:
Area = 15.36 ft
Step-by-step explanation:
First find the area of the dotted line triangle using the formula: base x height x 1/2, which would be 1.2ft x 12.8 x 1/2 = 7.68ft.
Next, add another triangle at the top, mirroring the shown triangle, of the parallelogram.
Then, find the area of the shape as though it were a rectangle. (base x height) - 2.4 x 12.8 = 30.72.
Next, multiply the area of the invisible triangle by 2, 7.68 x 2 = 15.36ft
and Finally, subtract the area of the rectangle shape of the the sum of the two invisible triangles, 30.72 - 15.36 = 15.36ft
The area of the parallelogram is 15.36 ft.
Answer:
3.00x10^8
Step-by-step explanation:
So you want to make sure the number before the x10^ is beween 10 and 0 not including 10 and 0. So 1.00-9.99.
Move the demcil place up in 300,000,000 till your first number is between 1 and 9.99.
Then count how many places you moved it up, in this case 8
Add the amount of times you moved up to the x10^(in this space).
you answer is now 3.00 plus the x10^8
3.00x10^8
Convert each to decimal form
that will be 0.122... , 0.1225, 0.12 and 0.056
so from greatest to least that is 0.1225 , 0.1222...., 0.12, 0.056
that is 0.1225 , 012(with bar over the 2) , 3/25 , 7/125
