In health class, students record the weights of the sandwiches they have for lunch. The weights are shown in the line plot below. What is the average weight of one sandwich?
Answers
The mean of the value of a data is the sum of the data divided by the sample size. The average weight of one sandwich is 3/10
How to calculate the mean of data?The mean of the value of a data is the sum of the data divided by the sample size.
Mean = sum/sample size
Find the mean
Sum = 1/8 + 1/8 + 4(1/4) + 2(3/8) + 2(1/2)
Sum = 1/4 + 1+ 3/4 + 1
Sum = 3
Sample size = 10
Mean = 3/10
Hence the average weight of one sandwich is 3/10

The required area of the rectangle with dimensions 13 yards long and 23 yards wide is 299 square yards.
How to calculate the area of the rectangle?In order to evaluate the area of the rectangle we must know the length and width of the rectangle and put this measure of length and width of the rectangle in the formula of area,
Area of the rectangle = length × width
Here,
From the question,
we have length = 23 yard and width = 13 yards
Area of the rectangle = 23 × 13

This cylindrical fish tank has a height of 36 inches and a diameter of 30 inches. What is the volume of the fish tank?
Answers
area of cross-section x the height.
First lets work out the area of the cross-section. Since the cross-section is a circle, we use the formula π x r²
Halve the the diameter to get the radius, so we can use the formula:
30 / 2 =15
Area of cross-section
π x 15² = 706.8583471 inches²
Now that we know the area of the cross-section, we multiply this by the height to get the volume.
706.8583471 x 36 = 25446.90049
= 25446.90 (2dp)
So the volume of the cylindrical fish tank is 25446.90
The volume of the cylindrical fish tank is 25446.90 inches cube.
What is the volume of a right circular cylinder?Suppose that the radius of considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
The formula for the volume of a cylinder is:
The area of cross-section x the height.
Since the cross-section is a circle, we use the formula π x r²
Radius= 30 / 2 =15
Thus, Area of cross-section
π x 15² = 706.8583471 inches²
Now that we know the area of the cross-section,
706.8583471 x 36 = 25446.90049
= 25446.90 (2dp)
So. the volume is 25446.90

In triangle XYZ, the length of side XY is 29 mm and the length of side YZ is 43 mm. Which of the following could be the length of side XZ?
Answers
The possible length of side XZ could be 50 mm
Which could be the length of side XZ?
From the question, we have the following parameters that can be used in our computation:
The length of side XY = 29 mmThe length of side YZ = 43 mmUsing the triangle inequality theorem, we have
Smallest length of XZ = 43 - 29
Smallest length of XZ = 14
Largest length of XZ = 43 + 29
Largest length of XZ = 72
So, we have
Range: 14 < x < 17
This means that the length of side XZ could be 50 mm because 50 is in the range 14 < x < 17

which number dose 5 represent a value 10 times the value represented by 5 in 35,187
Answers
In 35,187, the digit 5 represents 50,000. Ten times this value is 500,000. Therefore, in the new number, the digit 5 represents 500,000.
To find the value represented by the digit 5 in the number 35,187, we need to consider its place value. In the given number, 5 is in the ten-thousands place, which means it represents 5 * 10,000 or 50,000.
Now, we're asked to find a number where 5 represents a value ten times that of its representation in 35,187. So, we need to multiply 50,000 (the value represented by 5 in 35,187) by 10.
50,000× 10 = 500,000.
Therefore, in the new number, the digit 5 represents 500,000.
To summarize, the number where 5 represents a value ten times its representation in 35,187 is 500,000.

step 1
Find the slope

The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Find the equation of the line in slope intercept form

we have

amy has 30 grams of flour. she puts 4 grams of flour in each pot of chowder that she make. she puts 5 grams of flour in each pot of potato soup that she makes. she makes 4 pots of chowder. does amy have enough flour left over to makes 3 pots of potato soup.
Answers
After using 16 grams of flour to make 4 pots of chowder, Amy has only 14 grams of flour left, which is not enough to make 3 pots of potato soup, each requiring 5 grams of flour.
To solve this problem, we need to calculate the total amount of flour Amy uses for the chowder. Since she makes 4 pots of chowder, she would need:
4 pots × 4 grams/pot = 16 grams of flour
After making the chowder, Amy would have 30 grams - 16 grams = 14 grams of flour left.
Amy wants to make 3 pots of potato soup, and each pot requires 5 grams of flour. Therefore, she would need:
3 pots × 5 grams/pot = 15 grams of flour for the potato soup
Since Amy has only 14 grams of flour remaining, she does not have enough flour to make 3 pots of potato soup.
