When it was discovered, nobody knew how to read ancient Egyptian hieroglyphs. Because the inscriptions say the same thing in three different scripts, and scholars could still read Ancient Greek, the Rosetta Stone became a valuable key to deciphering the hieroglyphs!!

The linear combination method is applied to a system of equations as shown.

tensa zangetsu [6.8K]

Answer:

(9,3)

Step-by-step explanation:

4(.25x + .5y = 3.75) → x + 2y = 15

(4x – 8y = 12) → x – 2y = 3

2x = 18

Divide both sides by 2

x = 9

Substitute x = 9 into x + 2y = 15

9 + 2y = 15

Subtract 9 from both sides

2y = 6

Divide both sides by 2

y = 3

Solution

(9, 3)

When a cup of coffee at 100 degree Celsius cools down ,it loses 12%of its current temperature

polet [3.4K]

Answer:

Temperature after 10 minute = 27.9 degree Celsius

Step-by-step explanation:

Current temperature, P = 100 degree Celsius

% rate in temperature loses = 12% per minute = 0.12

Time, t = 10 minutes

Temperature after t minutes ,

$= P ( 1 - r )^t\\\\=100( 1 - 0.12)^10\\\\=100(0.278500976)\\\\=27.85$

= 27.9 degree Celsius

The largest possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'

<h3>Scale drawing</h3>

Scale drawing involves drawing a drawing in a different size and dimension that is proportional to the original dimension

<h3>Dimensions</h3>

The dimensions of the design for the farm scene painting is given as:

$12" \times 9"$

The dimensions of the wall is given as:

$24' \times 16'$

Convert feet to inches

$24' \times 16' = (24 \times 12") \times (16 \times 12")$

$24' \times 16' = (288") \times (192")$

Divide the dimensions of the wall by the painting to get the scale ratios (k)

$k = \frac{288}{12}$

$k = 24$

Also, we have:

$k =\frac{192}{9}$

$k =21.33$

Remove decimal (do not approximate)

$k =21$

By comparison;

21 is less than 24

Multiply 21 by the dimensions of the painting

So, we have:

$Length = 12 \times 21 = 252$

$Width = 9 \times 21 = 189$

Hence, the largest possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'
