Answer:

Explanation is below.

Step-by-step explanation:

Commutative property:

The Commutative property states that order does not matter. Multiplication and addition are commutative.

For example 2+5=5+2 .

Associative property:

The associative property states that you can add or multiply regardless of how the numbers are grouped.

For example 2x(7x5)=(2x7)x5

Distributive property:

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

For example 2(x+y)=2x+2y

Zero property of addition:

Zero is the additive identity. Adding zero to a number will not change its value. a + 0 = a.

For example 2z + 0 = 2z

Identity property of multiplication:

Property is that multiplying any number by 1 allows the number to keep its identity.

For example 14 x 1 = 14

Additive inverse:

The additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.

For example 13 + -13 = 0

Find the geometric mean of the pair numbers 6 and 10
inn [45]

Answer:

The geometric mean between 6 and 10 will be:

G.M=2\sqrt{15}

Step-by-step explanation:

We know that the geometric mean between the two numbers 'a' and 'b' is defined as:

G.M=\sqrt{a\times b}

Now, let us determine the geometric mean between 6 and 10

  • a = 6
  • b = 10

Using the formula

G.M=\sqrt{a\times b}

G.M=\sqrt{6\times 10}

        =\sqrt{60}

        =\:\sqrt{4\times 15}

        =2\sqrt{15}

 Therefore, the geometric mean between 6 and 10 will be:

G.M=2\sqrt{15}

On Friday, there were x students at the baseball game. On Monday, there were half as many students at the game as there were on
gayaneshka [121]

Answer:

2\frac{1}{2}x - 32

Step-by-step explanation:

On Friday, there were x students at the baseball game.

On Monday, there were 1/2 as many students, that is: x/2 students

On Wednesday, there were 32 fewer students at the game as there were on Friday, that is x - 32.

Tickets are sold for each student. Therefore, the number of tickets sold on all three days will be the same as the number of students that were at the games on the three days.

The number of students present on the three days is:

x + x/2 + x - 32

= 2x + \frac{1}{2}x - 32\\ \\= 2\frac{1}{2}x - 32

The number of tickets sold can therefore be represented by 2\frac{1}{2}x - 32

A firm has net working capital of $2,300 and current assets of $3,500. what is the current ratio?
Ulleksa [173]

Based on the net working capital and the current assets, the current ratio of the firm is 2.92

<h3>What is the firm's current ratio?</h3>

First, find the current liabilities:

= Current assets - Net working capital

= 3,500 - 2,300

= $1,200

The current ratio is:

= Current assets / Current liabilties

= 3,500 / 1,200

= 2.92

The vertices of a parallelogram are A(x1,y1), B(x2,y2), C(x3,y3), D(x4,y4)
Tju [1.3M]
<span>For a parallelogram to be proven to be a rectange, the opposide sides must be parallel and the two adjacent sides must be perpendicular. For two parallel sides, the slope of the two sides is equal. Thus, for the parallelogram to be a rectangle, AB is parallel to CD. The slope of AB = (y2 - y1)/(x2 - x1) while the slope of CD = (y4 - y3)/(x4 - x3) Also, BC is perpedicular to CD. For two perpendicular sides, the product of the slopes is -1. The slope of BC is given by (y3 - y2)/(x3 - x2). Therefore, for the parallelogram to be a rectangle. (y2 - y1)/(x2 - x1) = (y4 - y3)/(x4 - x3) and (y4 - y3)/(x4 - x3) x (y3 - y2)/(x3 - x2) = -1. The third option is the correct answer.</span>
