Answer:
The median is 5 and the range is 25
Answer:
A) Cm = 2.232 s/mm²
B) Time taken to solidify = 74.3 seconds
Explanation:
(A) Since a side is 50mm and all sides of a cube are equal, thus, Volume of the cube is;V = 50 x 50 x 50 = 125,000 mm³
There are 6 faces of the cube, thus Surface Area A = 6 x (50 x 50) = 15,000 mm²
So, Volume/Area = (V/A) = 125,000/15,000 = 8.333 mm
Cm is given by the formula; Cm =[Tts] /(V/A)² where Tts is time taken to solidify and it's 155 seconds in the question. Thus;
Cm = 155/(8.333)²= 2.232 s/mm²
(B) For;Cylindrical casting with D = 30 mm and L = 50 mm.;
Volume of cylinder is;
V = (πD²L) /4
So,V = (π x 30² x 50)/4 = 35,343mm³
Surface area of cylinder is;
A = (2πD²)/4 + (πDL)
Thus, A = ((π x 30²)/2) + (π x 30 x 50) = 6126 mm²
Volume/Area is;
V/A = 35,343/6126 = 5.77 mm
Same alloy and mold type was hsed as in a above, thus, Cm is still 2.232 s/mm²
Since Cm =[Tts] /(V/A)²
Making Tts the subject, we have;
Tts =Cm x (V/A)²
Tts = 2.232 x (5.77)² = 74.3 seconds
The amount of $700,000 is advisable to be deposited in three different banks for safety of Angelo's money.
<h3>What is a bank deposit?</h3>
A deposit of money made with a bank to earn returns in the form of interest on such money is known as a bank deposit. The banks insure such deposits up to a certain limit, say $250,000.
Angelo can distribute his money into three different banks, with each deposit not exceeding $250,000 to ensure the safety of his bank deposits.
Hence, the way to insure the safety of Angelo's money via bank deposit is aforementioned.

Answer:
45 miles
Explanation:
Speed = distance / time
Lets assume :
speed = x
Distance = D
Time = 3 hours
so in first case :
x = D / 3
D = 3x
Second case :
speed = x-5 ( he is traveling 5mph slower )
Distance = D ( Distance is same )
time = 4.5 hour
so,
x-5 = D / 4.5
D = 4.5(x-5)
since D is same in both cases.
3x = 4.5(x-5)
3x = 4.5x - 22.5
4.5x - 3x = 22.5
1.5x = 22.5
x = 22.5/1.5
x= 15
so speed is 15mph
D= 3x
so Distance = 3*15 = 45 Miles.
