A wire that is 48 centimeters long is shown below.

torisob [31]

Answer:

The sides of the square measure 6 cm

Step-by-step explanation:

If we cut the wire in half, we have to:

48/2 = 24

We would have two 24 cm wires

With each wire a square will be formed, therefore the question I suppose must be how much each side of the square measures.

We know that the square has 4 equal sides, therefore:

4/24 = 6

The sides of the square measure 6 cm

n 1895, the first Putting Green Championship was held. The winner’s prize money was $200. In 2016, the winner’s check was $1,480

Amanda [17]

Answer:

7.64% per year
$10,805,480 . . . . rounded to 7 significant figures

Step-by-step explanation:

Using 2016 as a reference (t=0), the exponential equation for winnings can be written as ...

w(t) = 1480000×(1480000/200)^(t/121)

where 1480000 is the winnings in the reference year, and the ratio 1480000/200 is the ratio of winnings increase over the 121 years from 1895 to 2016.

This can be approximated by ...

w(t) ≈ 1,480,000×1.07640850764^t

In this form, we can see that the annual percentage increase is ...

1.0764 -1 = 7.64%

Then the winner's check in 2043, 27 years after 2016, is predicted to be ...

w(27) = $1,480,000×(1.0764...)^27 ≈ $10,805,478.41 ≈ $10,805,000

Lori was paid a 15 percent commission for the home audio system that she sold. The electronics store had marked up the price of

svlad2 [7]

Answer:

$63.36

Step-by-step explanation:

The home audio system costs $264 wholesale.

The system's price had been increased by 60 percent at the electronics retailer.

Consequently, the increased cost is 60/100x264=$158.40.

The audio system's total cost is now $422.40 (264 + 158.40).

Given that Lori received a commission of = 15% on $422.40, her commission is now (15/100) x 422.40

= $63.36
