\frac{1.14}{100} =  \frac{n}{2000}

I will multiply the numerator by 20 because multiplying by 20 is how 100 became 2000
22.8 cases are rejected per hour.

An open box is to be constructed so that the length of the base is 3 times larger than the width of the base. If the cost to con
natta225 [31]

Answer:

Step-by-step explanation:

Let assume that the volume = 88 cubic feet

Then:

L = 3w --- (1)volume = l \times w \times h \\ \\ 88 =  (3w)   \times w  \times h \\ \\ 3w^2 h= 88 \\ \\ h = \dfrac{88}{3w^2}--- (2) \\ \\

The construction cost now is:

C = 4(l \times w) + 2 ( w  \times h) + 2(l \times h) \\ \\ C = 4(3w^2) + 2(w  \times \dfrac{88}{3w^2}) + 2(3w \times \dfrac{88}{3w^2}) \\\\ C = 12w^2 + \dfrac{176}{3w} + \dfrac{176}{w}

Now, to determine the minimum cost:

\dfrac{dC}{dw}= 0  \\ \\ \implies 24 w - \dfrac{176}{3w^2}- \dfrac{176}{w^2}=0 \\ \\ 24 w ^3 = \dfrac{176}{w^2}(\dfrac{1}{3}+1) \\ \\ 24 w ^3 = \dfrac{176(4)}{3} \\ \\ w^3 = \dfrac{88}{3(3)}

w = \dfrac{88}{3(3)}^{1/3} \ feet

Now;

length = 3 ( \dfrac{88}{3(3)})^{1/3} \ feet

height = ( 88})^{1/3} (3)^{1/3} \ feet

Someone please help with this,I’m no expert at doing annotated bibliography I will give Brainliest to whoever helps me out(:
Nitella [24]
An annotated bibliography includes the citation and a brief description of the source.

The citation can be made by plugging in information in an online citation website.

The description is 2 to 3 sentences about what type of source (primary or secondary) and how you used it (for the images, background info, etc).

What is the next number in the following series:
tester [92]

to get from 15 to 12 you subtract 3

to get from 12 to 17 you add 5

to get from 17 to 14 you subtract 3

to get from 14 to 19 you add 5

so, based on this pattern you can assume that you can get the next number by subtracting 3 from 19. so that means you'd do 19-3 and you would get 16 as your answer.


your answer is C.16

Hope this helps :)
