Answer:

shaded area = 8.7 ft²

Step-by-step explanation:

area of circle = πr² = (3.14)(4²) = 50.24 ft²

apothem of hexagon = (sin 60° x 4) = 3.464

area of hexagon = 1/2(3.464)(6)(4) = 41.56 ft²

50.24 - 41.56 = 8.68 ft²

Terri played 70 tournament chess games during the school year and won 49 of them. What is her win-to-loss ratio?
Scilla [17]

Alright so the answer would be letter B, because

win-to-loss

49 to 21 (You can determine her losses by subtracted the number of wins from her total number of games played)

Now you must simplify your answer

7 is the greatest common factor (GCF) of both 49 and 21

Now divide both 49 and 21 by 7 to get

7 to 3

which of the following best describes 4^2/3? a. sq root of 16, b. cube root of 4, c. sq root of four, d. cube root of 16
son4ous [18]

Answer: D) cube root of 16

================================================

Explanation:

The rule we use is

x^{m/n} = \sqrt[n]{x^m}

In this case, x = 4, m = 2 and n = 3.

So,

x^{m/n} = \sqrt[n]{x^m}\\\\\\4^{2/3} = \sqrt[3]{4^2}\\\\\\4^{2/3} = \sqrt[3]{16}\\\\\\

Showing that the original expression turns into the cube root of 16.

Butoxors [25]
That looks correct. If your graph let's you scroll upward, double check to see if the line crosses 1 on the x axis. as long as it never touches x=1, you answer is correct
