Explain how to determine whether two quantities are proportional.
Answers
Step-by-step explanation: Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

A cylindrical can of vegetables has a label wrapped around the outside, touching end to end. The only parts of the can not covered by the label are the circular top and bottom of the can. If the area of the label is 88π square inches and the radius of the can is 2 inches, what is the height of the can?
22 inches
11 inches
8 inches
4 inches
Answers
Answer:
22 inches
Step-by-step explanation:
The area of the label is the lateral area of the cylinder, which is given by the formula:
A = 2πrh
where r is the radius and h is the height of the cylinder.
We are given that the area of the label is 88π square inches and the radius is 2 inches. Substituting these values into the formula, we get:
88π = 2π(2)(h)
Simplifying, we get:
88 = 4h
Dividing both sides by 4, we get:
h = 22
Therefore, the height of the can is 22 inches. Answer: 22 inches.

A mixture contains 21.7 g NaCl,
3.74 g KCl, and 9.76 g LICI.
How many total moles are in this
mixture?
Answers
Answer:
Total moles = 0.6504 moles
Step-by-step explanation:
Molar mass of NaCl = Molar mass of Na + Molar mass of Cl
Molar mass of NaCl = 22.99 + 35.45 = 58.44 grams/moles
No. of mole of Nacl = grams/molar mass
No. of mole of Nacl = 21.7/58.44 = 0.371 mol
Similarly calculate for other two
Molar mass of KCl = 39.1 + 35.45 = 74.55 grams/moles
No. of mole of Kcl = 3.74/74.55 = 0.0502 mol
Molar mass of LiCl = 6.941 + 35.45 = 42.39 grams/moles
No. of moles of LiCl = 9.76/42.39 = 0.2302 mol
Total moles = 0.371 + 0.0502 + 0.2302
Total moles = 0.6504 moles
Answer:
0.371

Answers
Answer:
The equation for this would be x + 15 = 58.
Step-by-step explanation:
"More than" would refer to addition. So 15 more than x would be x + 15.
"Is" means "equals", so when they say "is 58" it means "equals 58."
Put it all together: x + 15 = 58.

58-15=43

Find the area of a right triangle with a base of 9 feet and a hypotenuse length of 13 feet and a base of 9 feet.(Round to the nearest tenth.)
Answers
Answer:
Step-by-step explanation:
Remark
The plan is to find the third side. It and the 9 foot side form a right angle. The base is given as 9 feet. The third sid will be the altitutude. The formula is Area = 1/2 * Base * third side.
Formulas
c^2 = b^2 + a^2
Area = 1/2 b * a
Givens
c = 13 feet
a = ?
b = 9 feet.
Answer: 42.2 square feet.
Solution
c^2 = b^2 + a^2
13^2 = 9^2 + a^2
169 = 81 + a^2 Subtract 81 from both sides.
169 - 81 =81 - 81 + a^2 Combine
88 = a^2 Take the square root of both sides
√a^2=√88
a = 9.381
Area = 1/2 * 9 * 9.381
Area = 42.21
Rounded to the nearest 1/10 Area = 42.2

The box plot shows the number of jumping jacks completed in a workout class by the class members. A box plot uses a number line from 14 to 54, with tick marks every one unit. The box extends from 26 to 49 on the number line. A line in the box is at 40. The lines outside the box end at 15 and 52. The graph is Jumping Jacks Completed, and the line is labeled Number of Jumping Jacks. Which of the following lists the range and IQR for this data? The range is 23, and the IQR is 37. The range is 40, and the IQR is 37. The range is 40, and the IQR is 23. The range is 37, and the IQR is 23.
Answers
- Range: The range is the difference between the maximum and minimum values in a data set.
- IQR: The IQR is the range of the middle 50% of the data values. It is calculated by finding the difference between the third quartile (Q3) and the first quartile (Q1).
In the given box plot:
- The lines outside the box represent the minimum and maximum values.
- The box represents the middle 50% of the data, with the line inside the box representing the median (or second quartile, Q2).
- The distance between the lower whisker and the bottom edge of the box represents the first quartile (Q1), and the distance between the upper whisker and the top edge of the box represents the third quartile (Q3).
Based on the information provided in the box plot, we can determine the range and IQR as follows:
- The minimum value is represented by the lower whisker, which ends at 15.
- The maximum value is represented by the upper whisker, which ends at 52.
- Q1 is located at the bottom edge of the box, which is 26.
- Q3 is located at the top edge of the box, which is 49.
Now we can calculate the range and IQR:
- Range: maximum value - minimum value = 52 - 15 = 37
- IQR: Q3 - Q1 = 49 - 26 = 23
Therefore, the correct statement is:
The range is 37, and the IQR is 23.
Answer:
The range is 37, and the IQR is 23.
Step-by-step explanation:
A box plot (also known as a "box and whisker plot"), is a graph displaying the distribution of a set of data based on a five-number summary.
Five-number summaryMinimum value is at the end of the left whisker.Lower quartile (Q₁) is the left side of the box.Median (Q₂) is the vertical line inside the box.Upper quartile (Q₃) is the right side of the boxMaximum value is at the end of the right whisker.From the given information, the five-number summary of the Jumping Jacks box plot is:
Minimum = 15Lower quartile (Q₁) = 26Median (Q₂) = 40Upper quartile (Q₃) = 49Maximum = 52RangeThe range is the difference between the maximum and minimum values. Therefore, the range for the data is:
\(\sf Range = 52 - 15 = \boxed{\sf 37}\)
Interquartile range (IQR)The IQR is the difference between the upper quartile and the lower quartile. Therefore, the IQR for the data is:
\(\sf IQR = Q_3 - Q_1 = 49 - 26 = \boxed{\sf 23}\)
SummaryThe range is 37, and the IQR is 23.

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

First find the area of the entire figure.
L= 36
W = 20
Area = 36 * 20 = 720
Find the area of the left right triangle.
Height = 20
Base = 1/2 * 36 = 18
Just as an aside, let me be a little grumpy for a moment. You should never have to guess what a dimension is on a diagram. It's sloppy. However for this problem you have no choice. But you could think to complain to your teacher.
Area = 1/2 * base * height
Area = 1/2 * 18 * 20 = 180
Find the area of the bottom right triangle.
The height is 1/2 20 = 10
The base is 36
Area of the lower triangle = 1/2 * 36 * 10 = 180
Area of the shaded figure = 720 - 180 - 180 = 360
