Answer:
7 days
Step-by-step explanation:
If there are 9 pages left, that means you have already read 70 pages.
Since you read 10 pages a day, we can find how many days you have been reading the book by dividing 70 by 10:
70/10
= 7
This means you have been reading the book for 7 days
How I’d do it:
5/6 three times makes 15/6. Made into a mixed fraction is 2 3/6, which in its simplest form is 2 1/2.
When converted to ounces, assuming that 6/6 is one complete ounce, then you get 2.5 ounces.
The total weight she picked up is 2.5 ounces.
Answer:
The constant of proportionality is 5.
Step-by-step explanation:
If the quantity q varies inversely with the square of m and directly with the product of r and x, then the variation equation is
![q=k\frac{rx}{m^2}](https://tex.z-dn.net/?f=q%3Dk%5Cfrac%7Brx%7D%7Bm%5E2%7D)
When q=2.5, m= 4 and the
product of rx = 8.
We plug in this values to get;
![2.5=k(\frac{8}{4^2})](https://tex.z-dn.net/?f=2.5%3Dk%28%5Cfrac%7B8%7D%7B4%5E2%7D%29)
![2.5=k(\frac{8}{16})](https://tex.z-dn.net/?f=2.5%3Dk%28%5Cfrac%7B8%7D%7B16%7D%29)
![2.5=\frac{1}{2}k](https://tex.z-dn.net/?f=2.5%3D%5Cfrac%7B1%7D%7B2%7Dk)
Multiply both sides by 2
![k=2.5\times 2=5](https://tex.z-dn.net/?f=k%3D2.5%5Ctimes%202%3D5)
The constant of proportionality is 5.
