Answer:
P = 2x² + 8x - 30
P = 12 (if x = 3)
Step-by-step explanation:
Perimeter Formula: 2l + 2w
Step 1: Find perimeter
2(2x² - 16) + 2(-x² + 4x + 1)
4x² - 32 - 2x² + 8x + 2
2x² + 8x - 30
Step 2: Plug in x = 3
2(3)² + 8(3) -30
18 + 24 - 30
42 - 30

Which layer of the earth is responsible for continental and oceanic plate movement?
(I know this is in the wrong category, I could not find the right one.)
A. crust
B. mantle
C. inner core
D. outer core
Answer: B. Mantle
Step-by-step explanation:
I just couldn't pass up answering this question. I think the earth is very interesting.
The Earth's mantle is a thick layer of hot, flowing rock that lies beneath the crust. Convection currents within the mantle are responsible for the movement of the Earth's tectonic plates, which make up the continents and the ocean floor. As the mantle convects, it drags the plates along with it, causing them to move and interact with each other at their boundaries. This movement is responsible for many geological phenomena, including earthquakes, volcanoes, and the formation of mountain ranges.
Delancey plans to run at least three miles each week for her health. Delancey has a circular route in the neighborhood to run. Once around that route is 220 yd. If Delancey runs that route 40 times during the week, will she cover at least 3 mi explain
Answer: Yes
Step-by-step explanation:
Since she wants to run the route 40 times we have to multiply the 220 yd route with how many times she wants to run it
40 x 220 = 8800 which is 5 miles
She reaches her goal and beyond that

The answer is 8 so its a direct proportion
I think...
The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

8. What is the interquartile range for the data in Table 3 (Number of Siblings)?
9. What is the mean absolute deviation of the data in Table 3 (Number of Siblings)?
Answer:
The data in Table 1 answers the question of what the distribution of heights is in Thomas's class.
The data in Table 2 answers the question of what the distribution of weights is in Thomas's class.
The data in Table 3 answers the question of what the distribution of number of siblings is in Thomas's class.
The most appropriate measure of center for the data in Table 1 is the mean. The mean is the average of all the values in the data set. In this case, the mean height is 5'8".
The mean height of the students in Thomas's class is 5'8".
The most appropriate measure of center for the data in Table 2 is the median. The median is the middle value in the data set. In this case, the median weight is 150 pounds.
The median weight of the students in Thomas's class is 150 pounds.
The interquartile range (IQR) is a measure of variability that is calculated by taking the difference between the third and first quartiles. In this case, the IQR is 25 pounds.
The mean absolute deviation (MAD) is a measure of variability that is calculated by taking the average of the absolute values of the differences between the data values and the mean. In this case, the MAD is 10 pounds.

Sanjay went blueberry picking along a 3-mile walking path. He picked blueberries steadily along the walk. When he was finished, he had collected 50 ounces of blueberries.
How many ounces of blueberries did Sanjay pick each mile?
Write your answer as a proper fraction or mixed number.
Answer:
16 2/3 per a mile
Step-by-step explanation:
50 ounces of blueberries/3 miles = 16.666 repeated
16.666 repeated = 16 2/3 ounces/mile
Answer: Sanjay picked 16.66 ounces each mile
Step-by-step explanation:
For this exercise let "x" represents the amount of ounces of blueberries that Sanjay picked each mile, along the 3-mile walking path.
According to the information given in the exercise, you know that Sanjay picked a total amount of 50 ounces of blueberries along the walking path.
Then, knowing that the length of that walking path is 3 miles, you can set up the following proportion:
\(\frac{3}{50} = \frac{1}{x}\)
Now, the next step is to solve for "x" in order to find its value.
You get that this is:
\((x)(\frac{3}{50} )=1\\\\x=(1)(\frac{3}{50} )\\\\x=16.66\)
Therefore, knowing the value of "x", you can conclude that Sanjay picked 16.66 ounces of blueberries each mile.
16.66 = 16 2/3
