Answer:
8.75 cups
Step-by-step explanation:
3.5:1 (the ratio of batches to 1 batch)
x:2.5 (the ratio of cups of sugar used to the amount used for only 1 batch)
3.5/1=x/2.5 (proportion)
x= 8.75
Answer:
11.45 lumens
Step-by-step explanation:
We are given that
![log(I/12)=-0.00235x](https://tex.z-dn.net/?f=log%28I%2F12%29%3D-0.00235x)
Where x=Depth
I=Intensity of light
We have to find the intensity of the light at a depth of 20 feet.
Substitute the value of x
![log(I/12)=-0.00235\times 20](https://tex.z-dn.net/?f=log%28I%2F12%29%3D-0.00235%5Ctimes%2020)
![log(I/12)=-0.047](https://tex.z-dn.net/?f=log%28I%2F12%29%3D-0.047)
![\frac{I}{12}=e^{-0.047}](https://tex.z-dn.net/?f=%5Cfrac%7BI%7D%7B12%7D%3De%5E%7B-0.047%7D)
![I=12e^{-0.047}](https://tex.z-dn.net/?f=I%3D12e%5E%7B-0.047%7D)
![I=11.45 Lumens](https://tex.z-dn.net/?f=I%3D11.45%20Lumens)
Hence, the intensity of the light (in lumens) at a depth of 20 feet=11.45 lumens
The answer would be the last option. :)
Answer:
12
Step-by-step explanation:
I think you have to use the product rule for counting- which is where you multiply the two numbers. I'm not sure if this is right but I hope I helped
The last one is rational because it is a terminating decimal.
