Painting is 2 in by 1.5 in. Scale is 1 in:40 cm. What are the dimensions of the original painting?

Answers

Answer 1

Answer:

Answer:

80 cm by 60 cm

Step-by-step explanation:

To solve this we know that the scale is 1 In: 40 Cm since our painting is already in inches all we have to do is multiply the inches by 40, so 2 inches * 40 is 80 and 1.5 * 40 is 60 and now all we do is turn the units into centimeters and we are done!

Answers

13.42 + 25.76 = 39.18 + 19.80 = 58.98

Answer: 58.98

Step-by-step explanation:

Answers

Answer:

Step-by-step explanation:

15^2 = 225 (memorize everything to 20, thank me later)

39^2 = 1521 (just use a calculator for everything higher)

225 + 1521

1521 =?= 45^2

45^2 = 2025

1521 =/= 2025

Just to be sure, I'll do 15^2 + 45^2 (going to be too much)

225 + 2025 = 2250

2250 =/= 1521

The answer would be a

Write the absolute value inequality in the form x−b ≤c or x−b ≥c that has the solution set −1≤x≤3.

Answers

The solution set of | x - 1 | ≤ 2 is -1 ≤ x ≤ 3, as required.

What is inequality?

A connection between two expressions or values that is not equal to each other is referred to as "inequality" in mathematics. The inequality can be resolved by adding the same amount to each side, subtracting the same amount from each side, multiplying or dividing each side by the same positive integer, and more. If you multiply or divide either side by a negative value, you must flip the inequality sign.

To write the absolute value inequality in the form x−b ≤c or x−b ≥c, we need to identify the midpoint between the lower and upper bounds of the solution set.

The midpoint is (3 - 1)/2 = 1.

Then, we can write the absolute value inequality as:

| x - 1 | ≤ 2

To verify that this inequality has the solution set -1 ≤ x ≤ 3, we can solve it as follows:

If x - 1 ≥ 0, then | x - 1 | = x - 1, and we have:

x - 1 ≤ 2

x ≤ 3

If x - 1 < 0, then | x - 1 | = - (x - 1), and we have:

(x - 1) ≤ 2

x - 1 ≥ -2

x ≥ -1

Therefore, | x - 1 | ≤ 2.
