A = wl
Simply divide both sides by w. This is done to isolate the variable we are solving for.
A/w = (wl)/w
A/w = l
Answer: Choice C
Answer:
The constant of proportionality is equal to 4
Step-by-step explanation:
The picture of the question in the attached figure
Let
y ----> the total cost in dollars
x ----> the number of bags of peanuts
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or ![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
To find out the constant of proportionality, we need to take one point from the graph
take the point (1,4)
Find the value of k
![k=\frac{y}{x}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7By%7D%7Bx%7D)
substitute the value of x and the value of y
![k=\frac{4}{1}=\$4\ per bag](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B4%7D%7B1%7D%3D%5C%244%5C%20per%20bag)
Answer:
729
Step-by-step explanation:
Raise 27 to the power of 2.
729
Answer:
-43
Step-by-step explanation:
Input 6 where a is so then do -7 x 6 which would be -42
the equation is now b = -1 - 42
-1 -42 = -43
Step-by-step explanation:
The scientific notation of any number is given by :
![N=a\times 10^b](https://tex.z-dn.net/?f=N%3Da%5Ctimes%2010%5Eb)
a is any real no and b is any integer
The scientific notation of 345,000,000 should be
but Jorden wrote 34.5×10⁷. He is incorrect. He should have shifted decimal before 4 such that power of 10 becomes 8.
