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}.

How much money does a newspaper delivery person get per year?
Vadim26 [7]

That depends on numerous factors, including how many papers must be delivered every day, and how many days/weeks/months per year are involved. Strictly as a guess: you'd probably earn between $8 and $16 per hour. If you were to deliver papers for 2 hours each day, that'd come to $112-$224 per 7-day week. And so on. Ask for specifics applying to your city / delivery area.

a tree 20 feet tall with a circumference of 3 ft has a vine wound around 7 times. How long is the vine?
FinnZ [79.3K]

If the tree is 20 feet tall with circumference 3 feet then the length of  vince is around 21 feet.

Given the height of tree is 20 feet and the circumference of tree is 3 feet.

We have to find the length of vine.

Circumference is the perimeter of a circular object. Because the trunk of a tree is in shape of circle so the perimeter of the trunk is 2πr.

We have been given the circumference of tree be 3 feet.

Circumference=2πr

Because vine is 7 times the circumference so the length of vine being:

Length of vine=7*3

=21 feet.

Hence if the tree is 20 feet tall with circumference 3 feet then the vince is around 21 feet long.
