How many different ways can a club choose a committee of 4 from 15 members?

boyakko [2]

It is done by this formula

combinations = n! / [r! * (n - r)!]

combinations = 15! / [4! * 11!]
combinations = 15 * 14 * 13 * 12 * 11! / [4! * 11!]
combinations = 15 * 14 * 13 * 12 / 4 * 3 * 2
combinations = 15 * 7 * 13
combinations = 1,365

answer is b

Apply the laws of exponents, calculate the result and express the result in scientific notation, and as a decimal:

vesna_86 [32]

Consider the expression $(8.1\cdot 10^{-4})^2.$

Use main properties for powers:

1. $(a\cdot b)^m=a^m\cdot b^m;$

2. $(a^m)^n=a^{m\cdot n};$

3. $a^m\cdot a^n=a^{m+n}.$

Then

$(8.1\cdot 10^{-4})^2=8.1^2\cdot (10^{-4})^2=65.61\cdot 10^{-4\cdot 2}=65.61\cdot 10^{-8}=6,561\cdot 10^{-2}\cdot 10^{-8}=6,561\cdot 10^{-10}.$

The result in scientific notation is $6,561\cdot 10^{-10}.$

The result as a decimal is $0.0000006561.$

If the circle below is cut from the square of plywood below, how many square inches of plywood would be left over? Use π = 3.14,

Elis [28]

Answer:

86in²

Step-by-step explanation:

Find the complete question attached

Area of the circle = πr²

Area of the square = L²

Length of the side of the square

r is the radius of the circle

r = L/2 = 20/2 =10in

Given

Length of the side of the circle = 20in

Area of the square = 20²

Area of the square = 400in²

Area of the circle =π(10)²

Area of the circle = 3.14(100)

Area of the circle= 314in²

Amount of plywood left over = 400in²-314in² = 86in²
