Answer:

As early as 1900 BC, geometers from ancient civilizations such as Babylon, India, and Egypt, are already aware of one fundamental property of the circle: that a circle’s circumference is always a little over three times that of its diameter. A more precise value was not available however as each of the civilizations computed pi only within 1% of its actual value.

A casserole recipe calls for 4 ounces of cheese. Adrian wants to use 1/2 of the amount of cheese in his casseroles. How many pou
denis-greek [22]

Answer:

She will need 3.5 pounds of cheese to make the 28 casseroles

Step-by-step explanation:

In this question, we are tasked with calculating the amount of cheese in pounds needed to make 28 casseroles.

In the revised recipe, she intends using 1/2 of what is supposed to be used in the original recipe. Mathematically, since each original casseroles is meant to take 4 ounces of cheese, the revised recipe taking half will have 1/2 × 4 = 2 ounces of cheese per casserole

Now for 28 casseroles based on the revised recipe, the total amount of cheese to be used mathematically is equal to 28 × 2 = 56 ounces of casserole

The questions asks that our answer be in pounds

Mathematically, 1 ounce = 0.0625 pounds

Hence, 56 ounces of casseroles will be 56 × 0.0625 = 3.5 pounds of cheese

Pythagorean theorem level 2 delta math
julsineya [31]

The third side is 4

So Pythagorean's theorem is the following

Short^2 + Long^2 = Hypotenuse^2

From here we can input the following information that we know

Short^2 + \sqrt{33}^2 = 7^2\\Short^2 + 33 = 49\\Short^2 = 49 - 33\\Short^2 = 16\\Short = \sqrt{16}\\Short = 4
