A spherical water tank holds 7500 feet^3 of water. what is the diameter?

1 answer:

6 0

Vsphere=4/3pir^3
7500=4/3pir^3
times both sides by 3
22500=4pir^3
divide both sides by 4
5625=pir^3
divide bot sides by pi
1790.4931=r^3
cube root both sides
12.142950=r

2r=d
d=24.28590063 ft

The paper usage at a small copy center is normally distributed with a mean of 5 boxes of paper per week, and a standard deviatio

VladimirAG [237]

Answer:

1.649 approximately 2

Step-by-step explanation:

S.d = standard deviation = 0.5

Time taken = lead time = 2 weeks

Mean = demand for week = 5 boxes

We are required to find the safety stock to maintain at 99% service level.

At 99% level, the Z value is equal to 2.326.

Therefore,

Safety stock = z × s.d × √Lt

= 2.326 × 0.5 x √2

= 1.649

Which is approximately 2.

Hey yall i would really appreciate your help on this plz

Katarina [22]

Answer:

the length of the opposite side (x), is 27.2

Step-by-step explanation:

For the given right triangle problem;

the opposite side of the given angle, opp. = 22

the hypothenuse side, hypo. = x

given angle of the triangle, θ = 54⁰

The length of the opposite side (x), is calculated as follows;

$sin \ \theta = \frac{opp.}{hypo.} \\\\sin (54) = \frac{22}{x} \\\\x = \frac{22}{sin(54)} \\\\x = 27.2$

Therefore, the length of the opposite side (x), is 27.2
