Amount of pizza dough that Rosa has = 4 1/2 pounds
= 9/2 pounds
Amount of dough required by Rosa to make 1 pizza = 3/4 pounds
Then
The number of pizza that can be made with 9/2 pounds of dough = 1/(3/4) * (9/2)
= (4/3) * (9/2)
= 2 * 3
= 6
So Rosa can make 6 pizzas with the amount of dough she has.
I hope the procedure is clear enough for you to understand.
Glad to have helped you.
Answer: y = - (1/4) |x|
Justification:
The statement is confusing, so I will re-write it to avoid confusions:
<span>
"The
graph of y=|x| is
reflected across the x-axis and then scaled vertically by a factor of
1/4. What is
the equation of the new graph?
"
Answer
Solution:
1) Reflection acros the x-axis means (a,b) transforms into (a, -b). That is for the given x the reflected function will return the negative of the original value, that is:
y = - |x|
2) Scaling by a factor of 1/4 means that the new function is multiplied by 1/4
=> y = - (1/4) |x| which is the answer

It would be 1649.04 cause 824.52+824.52=
0.07 * 1.22
Is equal to 0.0854
Answer:
Reasonable estimation for constant of variation is 0.25 kWh per day.
Step-by-step explanation:
We are given the following information in the question:
- The graph represents the function where electricity usage.
- Electricity usage in kilowatts per hour of a clock radio varies directly with the number of days.
- The x-axis shows the number of days and usage in kilo-watt per hour is showed on the y-axis.
- Some coordinates of the graph are: (0,0), (2,0.5) and (6,1.5)
Formula for constant of variation:
Putting the values from the coordinates (2,0.5) and (6,1.5), we get:
Hence, reasonable estimation for constant of variation is 0.25 kWh per day.
