Answer:
The expression for number of sandwiches is
9 small sandwiches can be made.
Step-by-step explanation:
Given:
Length of party-sized sandwich (l) = 3/4 yard
Length of each small sandwich (s) = 1/12 yard
Now, let the total number of small sandwiches be 'n'.
Now, sum of all the lengths of small sandwiches will be equal to the length of the party-sized sandwiches.
Therefore, framing in equation form, we have:
Length of large sandwich = Length of small sandwich × Total number of small sandwiches.
Now, plug in the given values and solve for 'n'. This gives,
Therefore, 9 small sandwiches can be made.
g(x) = (1/4)x^2 . correct option C) .
<u>Step-by-step explanation:</u>
Here we have , and we need to find g(x) from the graph . Let's find out:
We have , . From the graph we can see that g(x) is passing through point (2,1 ) . Let's substitute this point in all of the four options !
A . g(x) = (1/4x)^2
Putting (2,1) in equation g(x) = (x/4)^2 , we get :
⇒
⇒
Hence , wrong equation !
B . g(x) = 4x^2
Putting (2,1) in equation g(x) = 4x^2 , we get :
⇒
⇒
Hence , wrong equation !
C . g(x) = (1/4)x^2
Putting (2,1) in equation g(x) = (1/4)x^2 , we get :
⇒
⇒
Hence , right equation !
D . g(x) = (1/2)x^2
Putting (2,1) in equation g(x) = (1/2)x^2 , we get :
⇒
⇒
Hence , wrong equation !
Therefore , g(x) = (1/4)x^2 . correct option C) .
