Answer:
3.5 hr
Step-by-step explanation:
We assume that "the same rate" means effort per tree is a constant. "Effort" is measured as the product of lumberjacks and hours. Then ...
(lumberjacks)(hours)/trees = (6)(2)/15 = (8)(t)/35
Multiplying by 35/8, we have ...
(35/8)(12/15) = t = (3·4·5·7)/(2·3·4·5) = 7/2 = 3.5
It will take 8 lumberjacks 3.5 hours to cut down 35 trees.
Step-by-step explanation:
y=mx +c
given c = -8
a pont on line (-2,4)
subs all given info in formula to find m, the slope
Answer:
26ft
Step-by-step explanation:
This would form a triangle so you would use Pythagorean theorem to find the hypotenuse ( the longest side )
Going by the formula, Half-Life = ln(.5) / k
Half-Life = .693147 / .1205
Half-Life = 5.75 days and rounded to nearest tenth,
Half-Life = 5.8 days
Mike's plant plant height grew by 3 in
Lauren's grew 2 1/2 times of 3 in
So, 2 1/2 times of 3 in
= 2 1/2 x 3
= 5/2 x 3
= 15/2 = 7 1/2 inches
