Answer:
512 ft is the length of the field
Step-by-step explanation:
Firstly, we need to know the area of the field. We have confirmed this to be rectangular. Since it’s a rectangular field, the area of the field can be obtained by multiplying the length of the field by the breadth or width of the field.
Mathematically A = L * W
In the question, A = 210,944 ft^2
L= ? and W = 412ft
In essence, we are trying to calculate the value for the length of the field
L = A/W
L = (210,944)/412 = 512ft
Answer:
The numbers are -16,-15 and -14
Step-by-step explanation:
Let
x ----> the first number
x+1 ----> the second number
x+2 ---> the third number
we know that
(1/4)x+(1/5)(x+1)=(1/7)(x+2)-5
Multiply by (4*5*7) both sides
35x+28(x+1)=20(x+2)-140*5
35x+28x+28=20x+40-700
43x=-688
x=-16
so
x+1=16+1=-15
x+2=-16+2=-14
The numbers are -16,-15 and -14
If the fish eats 12 worms per minute and it needs to eat 510, we divide 510 by 12 to get 42.5 minutes
