Given:
A bricklayer is able to set 2.5 bricks in one minute.
Required:
To find the number of bricks can he set in 8 hours.
Explanation:
8 hours =480 minutes.
2.5 bricks in one minute.
So for 480 minutes,
Final Answer:
1,200 bricks can he set in 8 hours.
Less. If you only ate half of 3/4, then it would be impossible to eat more than that amount.
One may note, you didn't really include any "of the folllowing" ones
anyway... if we take the 3000 as the 100%, what's the 40% of that?
well
solve for "x"

Answer:
3
Step-by-step explanation:
Let x represent the number of interest. Then x+6 is "another number". You want its square root to be the original number:
√(x+6) = x
Squaring both sides, we get ...
x +6 = x^2
In standard form, this is ...
x^2 -x -6 = 0
(x -3)(x +2) = 0 . . . . factored
By the zero product rule, this will have solutions ...
x -3 = 0 ⇒ x = 3
x +2 = 0 ⇒ x = -2 . . . . . an extraneous solution, because √(-2+6) ≠ -2
The number is 3.
