The difference in the widths, in meters, of the human hair and the piece of sand is 1.4998*10^{-1} m.

It is given in the question that:-

Width of a human hair = 2*10^{-5} m

Width of a piece of sand = 1.5*10^{-1}m

We have to find the difference in the widths, in meters, of the human hair and the piece of sand.

We know that,

Difference between the widths = Width of a piece of sand - Width of a human hair

Hence, we can write,

Difference between the widths =  2*10^{-5} m - 1.5*10^{-1}m

We can write,

1.5*10^{-1}=15000*10^{-5}

Hence,

Difference between the widths =

15000*10^{-5} - 2*10^{-5}= 14998*10^{-5} = 1.4998*10^{-1} m

Rewrite the expression using the distributive property and a common factor.
Anestetic [448]

Answer:

  • x(27 +24)  or  3x(9 +8)
  • 0.5(n +5)  or  2.5(n/5 +1)

Step-by-step explanation:

The distributive property of multiplication over addition tells us that the product of a value and a sum will be the same as the sum of products of the value and the sum's addends. This property can be used to add or remove parentheses from an arithmetic expression.

  a(b +c) = ab +ac . . . . expression of the distributive property

__

When applying the distributive property to a sum, the first step is to look for a factor common to the terms of the sum. That factor need not be the greatest common factor, though it is often useful if it is.

Below, we have written each expression using two different common factors.

<h3>a)</h3>

  27x +24x = x(27 +24) = 3x(9 +8)

__

<h3>b)</h3>

  0.5n +2.5 = 0.5(n +5) = 2.5(n/5 +1)

_____

<em>Additional comment</em>

Finding a common factor can make use of knowledge of multiplication tables, rules of exponents, and identities involving various functions used in algebraic expressions. It is sometimes useful to list the prime factors of each of the terms as an aid to finding a common one. Where fractions are involved, it is sometimes helpful to express them all using a common denominator.

The Euclidean Algorithm can also be useful for finding common factors.

ABCD is a rectangle. Find the length of segment AC
Oksana_A [137]

Answer:

52

Step-by-step explanation:

First, find x. As BE and DE will have the same measurements, you can set your formula up as

5x+11=3x+17

5x=3x+17-11

5x-2x=6

2x=6

x=6/2

x=3

CE and AE will also have the same value, now substitute 3 in place of x to get the value of segment BE

5x+11

5*3+11 = 26

This also means that CE = 26 and AE = 26

AC = CE + AE

AC = 52

He has 4 wizard hats, 5 robes, and 6 wands. How many different outfit combinations does he have?
myrzilka [38]

Answer:

120 combinations

Step-by-step explanation:

This is asking how many permutations are possible, and assuming that he must wear exactly 1 hat, robe and wand, the result is this...

4 (hats) * 5 (robes) * 6 (wands)=120 different possible combinations
