Anita is eating popcorn at the movies. She eats 24 kernels in 10 minutes and 72 kernels in 30 minutes. Which TWO other ratios ca
Neporo4naja [7]

Answer:

\dfrac{96}{40} and \dfrac{120}{50}

Step-by-step explanation:

24 kernels in 10 minutes

In 1 minute she can eat \dfrac{24}{10}=\dfrac{12}{5}\ \text{kernels}

let x be the number of popcorn and minutes so the rate of eating popcorn is of the form

\dfrac{x12}{x5}

So, when x = 6 we get

\dfrac{6\times12}{6\times 5}=\dfrac{72\ \text{kernels}}{30\ \text{minutes}}

x can be any real number

\dfrac{10\times 12}{10\times 5}=\dfrac{120\ \text{kernels}}{50\ \text{minutes}}

\dfrac{8\times 12}{8\times 5}=\dfrac{96\ \text{kernels}}{40\ \text{minutes}}

Other two ratios can be \dfrac{96}{40} and \dfrac{120}{50}.

347 students said that they played sports. 58% said that they played basketball. How many students play basketball?
aliya0001 [1]

Answer:

201 students play basketball.

Step-by-step explanation:

total students who played sports = 347

58 % played basketball.

That is ,

   \frac{58}{100} \times 347 = 201.26

Since number of students cannot be in decimals we take the nearest whole number = 201.

On circle C points A and B are separated by an arc whose length is 18 centimeters. If the radius of C is 8 centimeters, what is
alex41 [277]

Answer:

2.25 radians

Step-by-step explanation:

First we need to find the length of the circunference, using the formula:

C = 2 * pi * r

Where r is the radius. Using r = 8, we have:

C = 2 * pi * 8 = 50.2655 cm

Now, to find the measure of the central angle related to that arc of 18 cm, we can use a rule of three, knowing that the whole circunference has a central angle of 2pi radians:

2pi rad -> 50.2655 cm

x -> 18 cm

x = 18 * 2pi / 50.2655

x = 2.25 rad
