Answer:
The largest possible volume V is ;
V = l^2 × h
V = 20^2 × 10 = 4000cm^3
Step-by-step explanation:
Given
Volume of a box = length × breadth × height= l×b×h
In this case the box have a square base. i.e l=b
Volume V = l^2 × h
The surface area of a square box
S = 2(lb+lh+bh)
S = 2(l^2 + lh + lh) since l=b
S = 2(l^2 + 2lh)
Given that the box is open top.
S = l^2 + 4lh
And Surface Area of the box is 1200cm^2
1200 = l^2 + 4lh ....1
Making h the subject of formula
h = (1200 - l^2)/4l .....2
Volume is given as
V = l^2 × h
V = l^2 ×(1200 - l^2)/4l
V = (1200l - l^3)/4
the maximum point is at dV/dl = 0
dV/dl = (1200 - 3l^2)/4
dV/dl = (1200 - 3l^2)/4 = 0
3l^2= 1200
l^2 = 1200/3 = 400
l = √400
I = 20cm
Since,
h = (1200 - l^2)/4l
h = (1200 - 20^2)/4×20
h = (800)/80
h = 10cm
The largest possible volume V is ;
V = l^2 × h
V = 20^2 × 10 = 4000cm^3
Answer:
The expected loss is $275 million.
Step-by-step explanation:
Expected loss can be determined as the sum of the product of each possible loss by the its probability of occurence. In this situation, there are only two possible losses listed since the probability of no loss doesn't add any value to the expected loss and should be disregarded.
Expected loss (in millions) = EL
The expected loss is $275 million.
Answer:
The answer is 27 miles and option b will give that.
Step-by-step explanation:
1.75 + 0.45m = 13.90
m = (13.90 - 1.75) / 0.45
m = 27 miles

Answer:
c) 2x+1
Step-by-step explanation:
Let's x be number of Nick's goals.
Emma has scored 1 more than twice the number of Nicks.
1 more is +1, of twices the number is 2x.
so 2x+1=15
