The question can't be answered with the information given.
First of all, we don't know how fast the rain is falling ... how many inches
per hour.
But even of we knew that, that would only tell us how much water would
pile up in our yard or on our street. You're talking about a river, and
that's a whole different ball game.
The rain that falls right here is going to flow down the river to somewhere
else. But the rain that falls up-river from us is going to flow down to where
we are, and the river is going to rise. The amount it rises depends on . . .
-- how fast the rain is falling,
-- how much area it's falling on,
-- how much forest there is in that area and how many houses and
parking lots where the ground can't soak up the water and hold it,
-- and also on how wide the river is and how fast the water can flow through it.
1 lb= 16 oz
3/4 of 16=12
therefore Ms. Winn bought 12 oz of grapes
Answer:
56 deg
Step-by-step explanation:
All internal angles of a triangle add up to 180 degrees
hence,
∠O + ∠R + ∠F = 180
x + (x+43) + (x-31) = 180
x + x+43 + x -31 = 180
3x+ 12 = 180
3x = 180 - 12 = 168
x = 168/3 = 56 deg
Hola!
A rational number could range from 10.21 to 10.2001
Hope that helped :)
Let width = w
Let length = l
Let area = A
3w+2l=1200
2l=1200-3w
l=1200-3/2
A=w*l
A=w*(1200-3w)/2
A=600w-(3/2)*w^2
If I set A=0 to find the roots, the maximum will be at wmax=-b/2a which is exactly 1/2 way between the roots-(3/2)*w^2+600w=0
-b=-600
2a=-3
-b/2a=-600/-3
-600/-3=200
w=200
And, since 3w+2l=1200
3*200+2l=1200
2l = 600
l = 300
The dimensions of the largest enclosure willbe when width = 200 ft and length = 300 ft
check answer:
3w+2l=1200
3*200+2*300=1200
600+600=1200
1200=1200
and A=w*l
A=200*300
A=60000 ft2
To see if this is max area change w and l slightly but still make 3w+2l=1200 true, like
w=200.1
l=299.85
A=299.85*200.1
A=59999.985
