Answer:

Step-by-step explanation:

First start by simplifying each expression.

To simplify \frac{4}{5} ÷ \frac{1}{12} you can use the method: Keep Change Flip to get \frac{4}{5} × \frac{12}{1}. Now you can simplify to get \frac{48}{5}. Then divide to get the decimal form of 9.6

For the expression: 1\frac{9}{13} ÷ \frac{1}{8}. First you must get both into improper fractions: \frac{22}{13} ÷ \frac{1}{8}. Now you can Keep Change Flip: \frac{22}{13} × \frac{8}{1}. Now multiply: \frac{176}{13}. Now you can divide to get the decimal form of about 13.54

Repeat the steps for the next expression. 1\frac{9}{13} ÷ \frac{1}{12}. Reduce both fractions to improper fractions: \frac{22}{13} ÷ \frac{1}{12}. Not Keep Change Flip: \frac{22}{13} × \frac{12}{1}. Now multiply: \frac{264}{13}. Next divide to get the decimal form of about 20.31.

For the last expression: \frac{4}{5} ÷ \frac{1}{8}. First start by Keep Change Flip: \frac{4}{5} × \frac{8}{1}. Now multiply to get: \frac{32}{5}.  Lastly divide to get the decimal form of 6.4.

Now that you have all decimal forms, you can now put them in order:

1. Least - \frac{4}{5} ÷ \frac{1}{8}

2. \frac{4}{5} ÷ \frac{1}{12}

3. 1\frac{9}{13} ÷ \frac{1}{8}

4. Greatest - 1\frac{9}{13} ÷ \frac{1}{12}

What is the range of this piecewise function
White raven [17]

Answer as a compound inequality: -4 \le y < 2

Answer in interval notation:  [-4, 2)

=============================================

Explanation:

The range is the set of all possible y outputs of a function. When dealing with a graph like this, we just look at the highest and lowest points to determine which y values are possible.

The lowest point occurs when y = -4. We include this value. So far we have y \ge -4 which is the same as -4 \le y

The upper ceiling for the y value is y = 2. We can't actually reach this value because of the open hole at (-3,2). So we say that y < 2

Combine -4 \le y and y < 2 to get the compound inequality -4 \le y < 2

This says y is between -4 and 2, including -4 but excluding 2.

To convert this to interval notation, we write [-4, 2) where the square bracket says to include the endpoint and the curved parenthesis says to exclude the endpoint.

Answer:

The actual wide of the lawn is 24 meters

Step-by-step explanation:

we know that

The scale drawing is

\frac{2}{1}\frac{mm}{m}

using proportion

Find out how wide  is the actual lawn if the lawn is 48 millimeters in the drawing

Let

x -----> the actual wide of the lawn

\frac{2}{1}\frac{mm}{m}=\frac{48}{x}\frac{mm}{m}\\\\x=48/2\\\\x=24\ m

therefore

The actual wide of the lawn is 24 meters

Which of the following choices translates the sentence “the difference of three times a number and 20 is 13”?
evablogger [386]

Answer:

3x - 20 = 13

Step-by-step explanation:

1. The word is signals the equal sign.

The difference of three times a number and 20 = 13

2. The word difference signals subtraction.

3. The phrase a number sigals that the number is unknown, so a variable should be used. In this case, I'll use x.

4. Three times that number = 3x.

The difference = subtraction.

3x-20=13
