To find out how much flour should Eric use for 1 cup of sugar, we need to compare the proportions between the amount of flour and sugar.
The recipe tells us that for every 2 1/2 pounds of flour, there is 1/4 cup of sugar.
To find out how much flour we need for 1 cup of sugar, we need to multiply the amount of flour by 4, because there are 4 1/4 cups in 1 cup.
4 x 2 1/2 = 10.
So, Eric should use 10 pounds of flour for 1 cup of sugar.
The answer is D. 10

Sara claims that the number of pages she has read in her book is proportional to the number of minutes that she has spent reading. She collects several data points to prove her claim and expresses the data points as (x, y) coordinate pairs.
Which of the following actions could Sara take to prove her claim?
A.
Place the coordinate pairs in a table and show that they do not create equivalent ratios.
B.
Use the coordinate pairs to show that an equation of the form y = x + c can be written.
C.
List out the coordinate pairs and show that each y-value is a multiple of its associated x-value.
D.
Plot the coordinate pairs on a graph and show that the points make a straight line through the origin.

D. Plot the coordinate pairs on a graph and show that the points make a straight line through the origin.
By plotting the coordinate pairs on a graph, if the points form a straight line through the origin (0,0), then it would indicate that the number of pages and the number of minutes spent reading are indeed proportional. This graphical representation can show the relationship between the variables and visually demonstrate the proportionality.

As part of an experiment in the science lab, a thermometer was inserted in a solution in order to measure the temperature over time. At 9:15 a.m. the temperature was –17 °C, and at 11:30 a.m. it was –26 °C.
What is the difference between these two measurements?
A.
8 °C
B.
9 °C
C.
11 °C
D.
43 °C

To find the difference between the two measurements, we subtract the initial temperature from the final temperature.
Final temperature: -26 °C
Initial temperature: -17 °C
-26 °C - (-17 °C) = -26 °C + 17 °C = -9 °C
Therefore, the difference between the two measurements is 9 °C.
The answer is B. 9 °C.
Final temperature: -26 °C
Initial temperature: -17 °C
-26 °C - (-17 °C) = -26 °C + 17 °C = -9 °C
Therefore, the difference between the two measurements is 9 °C.
The answer is B. 9 °C.
