An ice cream shop is testing some new flavors of ice cream. They invent 252525 new flavors for customers to try, and throw out t
navik [9.2K]

Answer:

Total <u>480 liters</u> of ice cream is in the cartons.

Step-by-step explanation:

Given:

An ice cream shop is testing some new flavors of ice cream. They invent 25 new flavors for customers to try, and throw out the 13 least popular flavors. The shop makes 80 cartons of each of the remaining flavors. It takes 2 cartons to get one liter of ice cream.

Now, to find the total ice cream in the cartons.

The ice cream shop invent new flavors = 25.

And ice cream shop throw out least popular flavors = 13.

So, to get the remaining ice cream we subtract quantity of flavors ice cream shop throw out from the quantity of flavors ice cream shop invent:

25-13=12.

Thus, the remaining flavors = 12.

<em>According to question, the shop makes 80 cartons of each of the remaining flavors. And it takes 2 cartons to get one liter of ice cream.</em>

So, we get the unit rate of liter per carton:

If, 2 cartons contain 1 liter.

Then, 1 carton contain = \frac{1}{2} =0.5\ liter.

<u><em>Total quantity of ice cream per carton = 0.5 liter</em></u>

<u><em>Total number of cartons = 80.</em></u>

<u><em>Total flavors of ice cream = 12.</em></u>

Now, to get the total ice cream in the cartons we multiply total quantity of ice cream per carton by total number of cartons by total flavors of ice cream:

0.5\times 80\times 12\\\\=480\ liters.

Therefore, total 480 liters of ice cream is in the cartons.

How to solve this question? please help me
Ber [7]

Use the Pythagorean theorem a^2 + b^2 = c^2

45^2 + 80^2 = c^2

2025 + 6400 = c^2

c^2 = 8425

c = √8425

c = 91.787

Rounded to the nearest foot = 92 feet

A circle is drawn inside a square so its circumference touches each of the four sides of the square. If the area of the circle i
Snowcat [4.5K]

Answer:

The length of the sides of the square is approximately 11.239 centimeters.

Step-by-step explanation:

Since the circle is inscribed in the square, the length of each side of the square (l), in centimeters, is equal to the length of the diameter of the circle (D), in centimeters. The area of the circle (A_{c}), in square centimeters:

A_{c} = \frac{\pi\cdot D^{2}}{4} (1)

Where D is the diameter of the circle, in centimeters.

If we know that A_{c} = 99.2\,cm^{2}, then the length of the sides of the square is:

D = \sqrt{\frac{4\cdot A_{c}}{\pi} }

l = D \approx 11.239\,cm

The length of the sides of the square is approximately 11.239 centimeters.
