Answer:
four hundred and forty two
Answer: There are 550 pages in the book
Explanation:
Since we have given that
Number of pages per hour Naoya read = 55
Number of hours he read the book = 4
Total number of pages he read is given by
![55\times 4=220](https://tex.z-dn.net/?f=55%5Ctimes%204%3D220)
Still there are some pages are left ,
Number of pages left = 330
So, total number of pages in the book is given by
![330+220=550](https://tex.z-dn.net/?f=330%2B220%3D550)
Hence, there are 550 pages in the book .
Answer:
(a) $6,412.12
(b) 6624.
Step-by-step explanation:
We have been given the total cost function for a product is
, where x is the number of units produced.
(a) To find the total cost of producing 400 units, we will substitute
in our given formula.
Therefore, the total cost of producing 400 units is $6,412.12.
(b) To find the number of units produced with total costs of $8500, we will substitute
in our given formula.
Switching sides:
Subtract 1900 from both sides:
![750\text{ ln}(x+10)=6600](https://tex.z-dn.net/?f=750%5Ctext%7B%20ln%7D%28x%2B10%29%3D6600)
Now, we will divide both sides of our equation by 750.
Using logarithm definition, we will get:
Therefore, producing 6624 units will give total costs of $8500.
Answer:
x=![\frac{y2 }{9}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20%7D%7B9%7D)
Step-by-step explanation:
2nd step: ![3\sqrt{x}=y](https://tex.z-dn.net/?f=3%5Csqrt%7Bx%7D%3Dy)
third step: ![\frac{3\sqrt{x} }{3} = \frac{y}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Csqrt%7Bx%7D%20%7D%7B3%7D%20%3D%20%5Cfrac%7By%7D%7B3%7D)
fourth step: ![\sqrt{x} =\frac{y}{3}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%3D%5Cfrac%7By%7D%7B3%7D)
answer: x=![\frac{y2 }{9}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20%7D%7B9%7D)
