The common ratio is the common multiple of consecutive terms, usually denoted as "r" for the common ratio.  Mathematically the common ratio is a constant that one finds when any term is divided by the term preceding it, in this case:

r=128/32=32/8=8/2=4

So the common ratio is 4.

Answer:

50 students

Step-by-step explanation:

Hello!  

To solve this question, we would first need to look at the data. In this data, there are people who chose their favorite sport, and the number of people who chose that response. In order to solve the problem, we would have to find the ratio of how many people choose baseball over the other sports.

By this, we can add the number of students together. 30+10+5+15=60. Out of those 60 students, only 5 people chose baseball.

Since the ratio of the people who chose baseball is 5/60 (meaning that it is a 5/60 % chance someone would pick this sport), we would need to find the amount of people assumed to pick baseball in 600 student survey.

We can make a relationship with these two numbers.

\frac{5}{60} =\frac{x}{600}, since the ratio of the students who chose baseball remain the same.

You can see that the ratio on the denominators just add a zero on the bottom, so the top should add 0 as well, to get 50 for x, what we needed.

You can also solve that relationship by cross multiplication.

5(600)=x(60

3000=60x

50=x

Regardless, the answer is 50 students who would choose baseball in a 600 persons survey.

a cone has a volume of 1,570in3. If the height of the cone is 15 inches. Calculate the radius of the cone?
spin [16.1K]

Answer:

approximately 10

Step-by-step explanation:

Volume = 1/3h times \pi times radius square

1570 = 1/3 x 15 x 22/7 x r^{2}

1570 = 5 times \frac{22}{7} times r^{2}

1570 = 15.71r^{2}

\frac{1570}{15.71} = \frac{15.71 r^{2}}{15.71}

99.9 = r^2

\sqrt{99.9} = r

≅10

<em>Greetings from Brasil...</em>

According to the annex, we note that

1 qt = 1 quart = 0.95L

To solve this problem, just apply some rules of 3.....

1st - how many qt's are in 15.5 cups

  qt                 cup

   1   ----------     4

   X  ----------   15.5

4 · X = 1 · 15.5

4X = 15.5

X = 15.5 ÷ 4

X = 3.875qt

Last rule of 3 to know how many liters there are in 3.875qt:

  qt                       litres

   1         ----------    0.95

3.875    ----------      Y

1 · Y = 0.95 · 3.875

<h2>Y = 3.68L</h2>

In a day a young man should drink 3.68L of water
