So for every one cup of pretzels (1p)
You have three cups of chex (3c)
The ratio between pretzels and chex is 1p:3c
Thus, changes in 1 is proportional with changes in 3.
You need a total of 12 cups of party mix. The sum of the ratio 1 cup of pretzels and 3 cups of chex is 4.
So you would need 3 cups of pretzels and 9 cups of chex for the ratio to equal a sum of 12.
Thus the answer is 3p:9c
Grab a calculator, a ruler, a piece of paper, a pencil, and a big text book and get to work!

Answer:
<em>Option C. is correct</em>
Step-by-step explanation:
<u>Slope of a Line</u>
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
Please note the slope measures the ratio of the change in y to the change in x.
The points of the graph are A=(-3,-2) B=(7,4). Calculating the slope:
Simplifying by 2:
Option C. is correct
17%
There are 30 students total. Out of those, there are 5 seniors. As a fraction: the probability is 5/30 or 1/6.
To convert to a percentage, you divide 5 by 30:
5/30=0.1666666667 which rounds to 0.17
To convert to a percentage, you must multiply the decimal by 100:
0.17*100=17
There is a 17% chance that the selected student will be a senior.
