13) If the area of your simming poolis 25
times larger than your neighbors, how
many times larger is your pool compared to
theirs? What is the sale factor?)​

Answers

Answer 1

Answer:

1. 25 times larger

2. The scale factor is 25:1

Step-by-step explanation:

Given

Let A represent the area of your swimming pool

Let a represents the area of your neighbour's swimming pool.

From the question, we understand that the area of your swimming pool is 25 times larger than the area of you neighbour's. This can be represented as follows;

A = 25 * a. --- divide through by a

A/a = 25 * a/a

A/a = 25

This means that your pool is 25 times larger than your neighbour's.

To get the scale factor, we have to convert the expression above to ratio

A/a = 25

This can be rewritten as

A/a = 25/1

By comparison the position of constraints at the left hand side to those at the right hand side of the equation

A = 25

a = 1

So,

A : a = 25 : 1

Hence, the scale factor is 25 : 1

3. Which of the following is equivalent to 3(y – 1 + 2y)? A. 3y – 9 B. 6y – 3 C. 9y – 3 D. 3y – 3

Answers

Final answer:

To solve the equation 3(y - 1 + 2y), distribute the 3 to each term inside the parentheses, combine like terms, resulting in 9y - 3.

Explanation:

To solve the equation 3(y - 1 + 2y), we need to distribute the 3 to each term inside the parentheses:

3 × y = 3y

3 × -1 = -3

3 × 2y = 6y

So the equation becomes 3y - 3 + 6y. Combining like terms, we get 9y - 3. Therefore, the correct equivalent expression is 9y - 3 (Option C).

Final answer:

The correct answer to the given expression 3(y – 1 + 2y) is 9y - 3, after distributing the 3 and combining like terms.

Explanation:

The given mathematical expression is 3(y – 1 + 2y). To simplify it, we should first distribute the 3 across the parentheses and then combine like terms. Here's how:

Step 1: Distribute the 3: 3 × y + 3 × (-1) + 3 × 2y = 3y - 3 + 6yStep 2: Combine like terms (3y and 6y): 3y + 6y = 9y, and you still have the -3 from the previous step.Step 3: The final simplified expression is 9y - 3.

Thus, the correct answer is C. 9y – 3.

How can you find 10% of any number without multiplying or dividing?

Answers

Answer:

subtract ---------

Step-by-step explanation:

To find value of the percentage of the number 10% of any number X without multiplying or dividing, divide X by 100 to get 1% and then multiply it by 10.

Let's say we want to find 10% of a number X. The key to this method lies in understanding that finding 10% of a number is the same as finding 1% of that number and then multiplying it by 10. To find 1% of X, we can divide X by 100, as 1% is equivalent to dividing by 100.

Step 1: Finding 1% of the number

1% of X = X / 100

Step 2: Finding 10% of the number

To get 10% of X, we multiply the 1% value by 10 since 10% is ten times greater than 1%.

10% of X = (X / 100) * 10

Now, let's demonstrate this method with an example:

Let's find 10% of 250.

Step 1: Finding 1% of 250

1% of 250 = 250 / 100 = 2.5

Step 2: Finding 10% of 250

10% of 250 = (2.5) * 10 = 25

So, 10% of 250 is 25.

Then add 46, "5x+7", and "180-12x+3"

46+5x+7+180-12x+3 = 180

Since the degrees in a triangle add up to 180 degrees, cancel out the 180 degrees from this side "180-12x+3" and the other side "180"
