120/360= 1/3
and so circumference is pi*diameter, so for this it would look like 24pi.
Then we solve: 1/3 *24pi =8pi feet

Gabrielle and Rob each earn $22 an hour, and each works 40 hours this week. Rob spends 1/2 of his earnings this week on bills an

Zielflug [23.3K]

The amount spent is an illustration of subtraction and proportions

The amount left in his earnings is $414.25

<h3>How to determine the amount left in his earnings?</h3>

The given parameters are:

Rate = $22 per hour

Time = 40 hours

So, the total earnings is:

Total = $22 * 40

Evaluate

Total = $880

He spent half on bills.

So, we have:

Bills = 0.5 * $880

Bills = $440

He buys a video game for $25.75

So, the amount left is

Amount left = $880 - $440 - $25.75

Amount left = $414.25

Hence, the amount left in his earnings is $414.25

Simplify the expression

AlexFokin [52]

Answer:

Step-by-step explanation:

$\frac{3+4\iota}{2+4\iota}=\frac{3+4 \iota}{2+4\iota} \times \frac{2-4 \iota}{2-4 \iota}\\=\frac{6 -12 \iota+8 \iota-16 \iota^2 }{4-16 \iota^2 }\\=\frac{ 6-4 \iota+16}{4+16}\\=\frac{22-4 \iota}{20}$

Based on the data set shown, which of the following is a true statement?

timama [110]

Answer:

mean = mode

Step-by-step explanation:

To make this easier, let's find the mean, median, and mode.

Mean: Sum of a set of numbers divided by number of terms

Median: Middle number of data when data is in numerical order

Mode: Number that occurs most often in data

To find the mean, add all the values together. -1 - 1 + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3 = 11. Now, divide by the number of terms, which is 11. 11/11 = 1. The mean is 1.

To find the median, look at the number in the middle of the data. -1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3. The median is 1.

To find the mode, look at the number that occurs most often. There are 4 1's, so the mode is 1.

Since all numbers are equal, the only possible answer is the first option.

How to write x is less than 5 and x is greater than 2

lesya [120]

Answer:

2 < x < 5

Step-by-step explanation:

<u>< This symbol means 'less than'</u>. The number you put on its left side is less than the number on its right side.

<u>> This symbol means 'greater than'</u>. The number put on its left is greater than its number on the right.

Think of them like a mouth. Remember the 'open side' wants to eat more.

Translate words to symbols:

'x is less than 5'

x < 5

'x is greater than 2'

x > 2

Put them together. The < and > symbols change directions, but x on the closed side of 5. Keep x on the open side of 2.

2 < x < 5

Don't confuse < and > with ≤ and ≥.

≤ and ≥ mean 'less than OR equal to' and greater than OR equation to'.

The mean weight of the packages Joan shipped was 2.5 pounds. If Joan mailed four packages and three of them had weights of 1.7,

Blababa [14]

The mean weight of the packages is 2.5, so the total weight of the packages is found by multiplying 2.5 pounds by 4 which is equal to 10 pounds. That is the tial weight of the four books. To find the weight of the fourth book, the three other weights are subtracted from 10 pounds:
$10 - 1.7 - 3.2 - 2.8 = 2.3 pounds$
