Answer:
64.28 miles per hour
Step-by-step explanation:
I divided the seven by the 450
Answer:
12m²
Step-by-step explanation:
For a rectangle, with length L and width W,
the perimeter is given as
Perimeter,
P = (2 x Length) + (2 x Width)
P = 2L + 2W
It is given that the perimeter is 48, hence
48 = 2L + 2W (divide both sides by 2)
24 = L + W
or
L = 24 - W -----> eq 1
Also realize that the Area of a Rectangle is given by
A = L x W -----> eq 2
Substituting eq 1 into eq 2,
A = (24 - W) x W
A = -W² + 24W
Recall that for a quadratic equation y = ax² + bx + c, the maxima or minima is given by y(max) = -b/2a
In this case, b = 24 and a = -1
-b/2a = -24/[ 2(-1) ] = 12
Hence for A to be maximum A(max) = 12m² (Answer)
Answer:
x =550
y=250
Step-by-step explanation:
.2x + .04y = 120
x + y = 800
Hi!
We will solve this using proportions, like this:
3/4 cup for 8 slices of pie
x cup for 48 slices of pie
_______________________
x = ((3/4)*48)/8
x = (3*48)/(4*8)
x = 144/32
x = 4,5
You need 4 1/2 cups of white sugar for 48 slices of pie.
Hope this helps!
the volume of the cone would be 2.36 I hope this helps ❤️
