Question A: The dimensions of the original painting are 42 cm by 126 cm.

Question B: The area of the original painting is 5292cm^2

Question C: The dimensions of the painting in feet are 1.386 ft by 4.158 ft.

Step-by-step explanation:

Question A:

The scale of the copy is

0.5 inches:12 centimeter.

This means that 1 inch on the scale is 24 centimeters.

Therefore the width of the original painting is:

1.75*24cm=42cm

and the height of is:

5.25*24cm=126cm

Therefore the dimension of the original painting are 42 cm by 126 cm.

Question B;

The area of the original painting is just width multiplied by height:

Area=42cm*126cm=5292cm^2

Question C:

We convert the dimensions of the painting from centimeters to feet:

$width=42cm*0.033\frac{feet}{cm} =1.386\:feet.$

$height=126cm*0.033\frac{feet}{cm} =4.158\:feet.$

Therefore the dimensions of the original painting in feet are 1.386 ft by 4.158 ft.

Answer from: isalih7256

(A) 42 cm by 126 cm.(B) 5,292 square centimeters.(C) 1.386 feet by 4.158 feet

Step-by-step explanation:

The scale of the copy is 0.5 : 12, which means 0.5 inches of the copy represents 12 centimeters actual.

From the given scale we can deduct that 1 inch equals 24 centimeters.

So, the dimensions of the original are

$1.75 \times 24 =42$

$5.25 \times 24= 126$

Therefore, the original painting has dimensions 42 cm by 126 cm. (A)

Notice that the original painting is also rectangular, so its area is

$A_{original}=42 \times 126 = 5,292 cm^{2}$ (B)

Now, if 1 centimeter is equivalen to 0.033 foot, the dimensions of the original painting in feet are

$42 \times 0.033 =1.386 ft\\126 \times 0.033=4.158 ft$

Therefore, the dimensions in feet are 1.386 feet by 4.158. (C)

Answer from: Quest

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

Answer from: Quest

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
