Tom drinks 8 oz of water for every 3
miles he bikes. After 21 miles, how
much water did he drink?
Answer:
56 oz of water
Step-by-step explanation:
Answer:
56 oz
Step-by-step explanation:
He stops 7 times in 21 miles because he stops every 3 miles and 21 divided by 3 equals 7. He also drinks 8 oz of water every time he stops, and if he stops 7 times then we just multiply 8 and 7, and since 8×7=56 he drank 56 oz of water after 21 miles.

What is the slope of the line with equation y-3=-1/2 (x-2)
Given parameters:
Equation of the straight line;
y - 3 = [tex]\frac{-1}{2}[/tex](x -2)
We can determine the slope of any straight line from the equation of such lines.
Generally, a straight line has the formula;
y = mx + C
where y is the y-axis coordinate and x is the x-axis coordinate
m is the slope and c is the y-axis intercept
Now let us express the given equation in this format;
y - 3 = [tex]\frac{-1}{2}[/tex](x - 2)
Multiply both sides by 2;
2(y - 3) = -1(x -2)
2y -6 = -x + 2
Rearrange to the form y = mx + c
2y = -x + 2 + 6
2y = -x + 8
divide by 2;
y = [tex]\frac{-1}{2}[/tex]x + 4
y = mx + c
the slope is m and it is equal to [tex]\frac{-1}{2}[/tex]

The scatter plot shows the relationship between the number of smoothies sold and the high Temperature on that day. The graph displays a pattern of upward trend, indicating that as the temperature increases, the number of smoothies sold also increases.
A concession stand sells smoothies. The scatter plot shows the relationship between the number of smoothies sold and the high temperature on that day. The graph indicates a positive correlation between the two variables. The scatter plot displays a pattern of upward trend, suggesting that as the temperature increases, the number of smoothies sold also increases. Let's understand what scatter plots are and how they are useful in depicting data in detail.Scatter Plots:
Scatter plots are a graphical representation that displays data as a collection of points in a two-dimensional coordinate system. In simple terms, they use dots to show the relationship between two variables. They are useful in identifying patterns, trends, and correlation between variables. In the case of a concession stand selling smoothies, a scatter plot can be used to show the relationship between the number of smoothies sold and the temperature on that day.Positive Correlation:
Positive correlation indicates that as one variable increases, the other variable also increases. In the case of the concession stand selling smoothies, the scatter plot shows a pattern of upward trend, suggesting that as the temperature increases, the number of smoothies sold also increases. This means that the variables have a positive correlation, and an increase in one variable causes an increase in the other variable.
Therefore, we can conclude that the scatter plot shows the relationship between the number of smoothies sold and the high temperature on that day. The graph displays a pattern of upward trend, indicating that as the temperature increases, the number of smoothies sold also increases. The variables have a positive correlation, which means that an increase in one variable causes an increase in the other variable. Scatter plots are useful in identifying trends and patterns and can be used to depict data graphically.

3. Suppose a unit cube is dilated by some scale factor k a. Write an expression for the surface area of the dilated cube. b. Write an expression for the volume of the dilated cube. c. Compare and contrast the expression for surface area and the expression for volume.
a. The expression for the surface area of a dilated cube is 6k², where k is the scale factor.
b. The expression for the volume of a dilated cube is k³, where k is the scale factor.
c. The expressions for surface area and volume differ in terms of the power of the scale factor: surface area is proportional to k², while volume is proportional to k³.
a. When a unit cube is dilated by a scale factor k, all sides of the cube are multiplied by k. Since a cube has six faces, the surface area of the dilated cube can be calculated by multiplying the area of one face (which is k²) by 6. Therefore, the expression for the surface area of the dilated cube is 6k².
b. The volume of a cube is calculated by multiplying the length, width, and height of the cube. In this case, each side of the unit cube is scaled by a factor of k, so the expression for the volume of the dilated cube is k³.
c. Comparing the expressions for surface area and volume, we observe that the power of the scale factor differs. The surface area is proportional to k², indicating that the surface expands in two dimensions (length and width) when the scale factor increases. On the other hand, the volume is proportional to k³, demonstrating that the space inside the cube expands in three dimensions (length, width, and height) as the scale factor increases. This means that the volume of the dilated cube increases faster than its surface area as the scale factor grows, resulting in a greater change in volume compared to the change in surface area.

An ant starts at the point (1, 0) on the unit circle and walks counterclockwise a distance of 2 units around the circle. Find the a and y coordinates (accurate to 2 decimal places) of the final location of the final location of the ant.
To find the final location of the ant after it has walked counterclockwise a distance of 2 units around the unit circle, we need to calculate the coordinates (x, y) of the point.
Since the ant starts at the point (1, 0) on the unit circle, we can think of this point as being at an angle of 0 degrees or 0 radians.
To find the coordinates after walking a distance of 2 units counterclockwise, we can calculate the new angle using the arc length formula:
s = rθ
where s is the arc length, r is the radius of the circle (which is 1 in this case), and θ is the angle in radians.
In this case, the arc length is 2 units and the radius is 1, so we have:
2 = 1θ
Solving for θ, we find:
θ = 2 radians
Now, we can use this angle to find the coordinates (x, y) of the final location on the unit circle:
x = cos(θ)
y = sin(θ)
Plugging in θ = 2, we get:
x = cos(2) ≈ -0.42
y = sin(2) ≈ 0.91
Therefore, the approximate coordinates of the final location of the ant are (-0.42, 0.91).

| 55-64 | 2 | 120 |
(b) The cumulative frequency curve starts from the origin (0, 0) and moves upward and to the right, indicating that the mass of logs is increasing as we move right on the x-axis.
To construct the cumulative frequency table for the distribution of masses of 120 logs of wood, we need to add up the frequencies of each class and all the classes before it.
(b) To draw a cumulative frequency curve, we plot the cumulative frequency values against the upper class limits. The plot shows how the cumulative frequency increases with the increase in the mass of the log.
We use the same class intervals as in part (a):
- x-axis = Masses (kg)
- y-axis = Cumulative frequency
To plot the cumulative frequency curve, we mark the upper limit of each class on the x-axis, and its corresponding cumulative frequency on the y-axis. Then, we join the plotted points with a smooth curve, as shown in the graph.
The steeper the curve, the more rapid the increase in cumulative frequency, indicating that a larger number of logs fall in higher mass categories.
In the given distribution, the plot of the cumulative frequency curve shows that the majority of logs fall in the mass range of 25-34 kg, closely followed by the range of 45-54 kg.
