Answer 1

Answer:

Answer:

The product 12 × 15 in friendlier numbers is (10 + 2) × (10 + 5) = 180

Step-by-step explanation:

The parameter given are;

To 12 × 15 by changing the numbers into friendlier numbers

The product in 12 × 15 written with friendlier numbers (or in a simplified format can be given as follows;

12 × 15 = (10 + 2) × (10 + 5)

Which gives;

(10 + 2) × (10 + 5) = 10² + 10 × 5 + 2 × 10 + 2 × 5

From which we have;

10² + 10 × 5 + 2 × 10 + 2 × 5 = 100 + 50 + 20 + 10 = 180

Therefore;

12 × 15 = 180.

Answer 2

Answer:

Final answer:

To calculate 12 x 15 using friendlier numbers, break down 15 into 10 and 5, multiply these by 12 to get 120 and 60 respectively, then add these together to get 180.

Explanation:

To calculate 12 x 15 using friendlier numbers, you can break either 12 or 15 down into numbers that are easier to multiply and then combine those results. Here, we'll break down 15 into 10 and 5, which are friendlier numbers.

First, multiply 12 by 10: 12 x 10 = 120.
Next, multiply 12 by 5: 12 x 5 = 60.
Finally, add the two results together: 120 + 60 = 180.

So, 12 x 15 = 180 using friendlier numbers.

Triangle UVW is drawn with vertices at U(−1, 1), V(0, −4), W(−4, −1). Determine the coordinates of the vertices for the image, triangle U′V′W′, if the preimage is rotated 90° counterclockwise

Answers

The coordinates of the vertices for the image, triangle U′V′W′, if the preimage is rotated 90° counterclockwise include the following:

U' = (1, 1).

V' = (-4, 0).

W' = (-1, 4).

What is a rotation?

In Mathematics and Geometry, the rotation of a point 90° about the center (origin) in a counterclockwise (anticlockwise) direction would produce a point that has these coordinates (-y, x).

By applying a rotation of 90° counterclockwise to the vertices of triangle UVW, the coordinates of the vertices of the image are as follows:

(x, y) → (-y, x)

Ordered pair U = (-1, 1) → Ordered pair U' = (1, -(-1)) = (1, 1).

Ordered pair V = (0, -4) → Ordered pair V' = (-4, -(0)) = (-4, 0).

Ordered pair W = (-4, -1) → Ordered pair W' = (-1, -(-4)) = (-1, 4).

What best describes the number 5? write prime, composite, neither prime nor composite, or both.

Answers

The number 5 is a prime because prime can be divided evenly by 1, or itself. And it must be a whole number greater than 1.

Here is an example:

5 can only be divided evenly by 1 or 5, so it is a prime number. But 6 can be divided evenly by 1, 2, 3, and 6 so it is NOT a prime number (it is a composite number).

So 5 is a prime number.
