C. 150 layers of lace
Because you times the 50 three times because a yard is 3 feet
3 - 14 = -11
Because you do 14 - 3 which equals eleven and then you add the negative sign
Answer:
Dimensions will be
Length = 7.23 cm
Width = 7.23 cm
Height = 9.64 cm
Step-by-step explanation:
A closed box has length = l cm
width of the box = w cm
height of the box = h cm
Volume of the rectangular box = lwh
504 = lwh

Sides which involve length and width and height, cost = 3 cents per cm²
Top and bottom of the box costs = 4 cents per cm²
Cost of the sides
= 3[2(l + w)h] = 6(l + w)h
= 3[2(l + w)h]

Cost of the top and the bottom
= 4(2lw) = 8lw
Total cost of the box C =
+ 8lw
=
+ 8lw
To minimize the cost of the sides


---------(1)


-------(2)
Now place the value of w from equation (1) to equation (2)


l³ = 378
l = ∛378 = 7.23 cm
From equation (2)


w = 7.23 cm
As lwh = 504 cm³
(7.23)²h = 504

h = 9.64 cm

Step-by-step explanation:
we have given that emails arrives at the server at the rate of 10 per hour means
per minute
we have to find the probability that the time difference between the two email is more than 2 minute
so probability
