Answer:
A. supplementary
Step-by-step explanation:
Note the angle measurements of BOC. m∠BOC = 90°
Now note that line FC is a straight line, which makes it's measurement = 180°
Subtract 90 from 180: 180 - 90 = 90°
Both are 90°, which, when combined makes a supplementary angle.
Answer:
The volume of the fish tank is 48000 cubic centi meter.
Step-by-step explanation:
The volume of a Cuboid is l*b*h (length*breadth*height)
Here,
length(l) =60 cm
breadth(b)= 20 cm
height(h)=40 cm
Volume=l*b*h
Volume= 60cm*20cm*40cm
Volume= 48000 cubic centimeter
Answer:
n = -5
I think the answer is -5, because:
The last number in the operation has a negative sign.
This can be a reason that it is-5.
Hope it helps!
Answer:
20 ft by 60 ft
Step-by-step explanation:
"What should the dimensions of the garden be to maximize this area?"
If y is the length of the garden, parallel to the stream, and x is the width of the garden, then the amount of fencing is:
120 = 3x + y
And the area is:
A = xy
Use substitution:
A = x (120 − 3x)
A = -3x² + 120x
This is a downward facing parabola. The maximum is at the vertex, which we can find using x = -b/(2a).
x = -120 / (2 · -3)
x = 20
When x = 20, y = 60. So the garden should be 20 ft by 60 ft.
