Using proportions, it is found that the computer will cost $1,043.04.

<h3>What is a proportion?</h3>

A proportion is a fraction of total amount.

In this problem, the total amount is composed by:

  • An initial payment of $150.
  • 12 payments of $69.50.
  • 6% sales tax, which means that the price is increased by 6%, that is, the previous amount is multiplied by 1.06.

Hence, the cost is given by:

C = 1.06 x (150 + 12 x 69.50) = 1043.04.

The computer will cost $1,043.04.

The following examples illustrate the associative property of multiplication.
kati45 [8]

Answer:

A) a • (b • c) = (a • b) • c

Step-by-step explanation:

The associative property of multiplication (or addition) shows that the order the numbers are multiplied it irrelevant, more specifically in the manners of parentheses.

So, the answer is A, which can also be seen in that substituting a as 5, b as 3, and c as 6 gives us the first example.

I need help asap. I don’t know how to do this
irga5000 [103]

Answer:

  10 in

Step-by-step explanation:

There are two ways to work this problem, and they give different answers. The reason for that is that <em>the data shown in the diagram is not consistent</em>.

<u>Method 1</u>

Use the area to determine the base length. The area formula is ...

  A = (1/2)bh

  20 in^2 = (1/2)(b)(4 in)

  (20 in^2)/(2 in) = b = 10 in

The missing side dimension is 10 inches.

__

<u>Method 2</u>

Use the Pythagorean theorem to find the parts of the base, then add them up.

Left of the "?" we have ...

  left^2 +4^ = 6^

  left^2 = 36 -16 = 20

  left = √20 = 2√5

Right of the "?" we have ...

  right^2 +4^2 = 8^2

  right^2 = 64 -16 = 48

  right = √48 = 4√3

So, the base length is ...

  base = left + right = 2√5 +4√3

  base ≈ 11.400 in

The missing side dimension is 11.4 inches. (The area is 22.8 in^2.)

PLEASE HELP ASAAP 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER
Nutka1998 [239]

Let i = sqrt(-1) which is the conventional notation to set up an imaginary number

The idea is to break up the radicand, aka stuff under the square root, to simplify

sqrt(-8) = sqrt(-1*4*2)

sqrt(-8) = sqrt(-1)*sqrt(4)*sqrt(2)

sqrt(-8) = i*2*sqrt(2)

sqrt(-8) = 2i*sqrt(2)

<h3>Answer is choice A</h3>
