Step-by-step explanation:
Answer:Astrid needs 280 tons of wood
Step-by-step explanation:
Because:
1 ship requires 40 tons of wood=accomodates 300 sailors
We must:
2100, sailors needed to be accomodated
÷
300, sailors that can be accomodated by 1 ship that requires 40 tons of wood
=7 groups of 300 sailors that can be accomodated by 1 ship that requires 40 tons of wood.
So:
I ship that requires 40 tons of wood × the 7, groups = 280 tons of wood.
I hope this helps! Im sorry its too complicated.
Simplier:
2100 ÷ 300= 7
40 × 7= 280
Set up a system of equations:
s = 2d - 5
s + d = 43
Where 's' represents the number of points Stilt scored and 'd' represents the number of points Dunk scored.
Plug in 2d - 5 for 's' in the 2nd equation:
s + d = 43
2d - 5 + d = 43
Combine like terms:
3d - 5 = 43
Add 5 to both sides:
3d = 48
Divide 3 to both sides:
d = 16
Plug this back into any of the two equations to find 's':
s + d = 43
s + 16 = 43
Subtract 16 to both sides:
s = 27
So Dunk scored 16 points and Stilt scored 27 points.
Answer:
Step-by-step explanation:
The formula primarily used for finding the derivative of a square root is
d/dx(x^n) = nx^(n - 1)
and so:
(d/dx)(x^(1/2)) = (1/2)x^(1/2 - 1), or:
1
(1/2)x^(-1/2), or, in radical form, ---------
2√x
When one (not two!) of them is negative:
for example the product of -1 and 6 is -6, which is less than both factors.
It's equal to both factors when they're both 1:
1 x 1=1
