Answer:
8 ± √34 ≈ {2.169, 13.831}
Step-by-step explanation:
Let x represent one of the numbers. Then the other is 16 -x and their product is ...
x(16 -x) = 30
x^2 -16x = -30 . . . . . eliminate parentheses, multiply by -1
x^2 -16x +64 = 34 . . . . add 64 to complete the square
(x -8)^2 = 34 . . . . . . . . rewrite
x -8 = ±√34 . . . . . . . .square root
x = 8 ± √34 . . . . . . add 8
x ≈ {2.169, 13.831}
Answer:
$36.00
Step-by-step explanation:
The formula for simple interest is I = P x r x t where P is the principal amount, $600.00, r is the interest rate, 2% per year, or in decimal form, 2/100=0.02, and t is the time involved, 3....year(s) time periods. So t is 3....year time periods. To find the simple interest, we multiply 600 × 0.02 × 3 to get that the interest is $36.00 . Usually now, the interest is added onto the principal to figure some new amount after 3 year(s), or 600.00 + 36.00 = 636.00.
As decimals lets look at them:)
7/8 = 0.875
3/4 = 0.75
In this case 7/8 is actually bigger.

I think it's D. The area of A is k2 times the area of rectangle B
C
it appears that there are 7 cubes, so divide the overall volume by the seven cubes, making the volume of each one would 8. Volume is length times with times height so you would find the cube root of eight which is two. This means that each side length is 2 so you would find the area of each side and add them all together. This adds up to equal 120.
Hope this helped!!
