Answer:
B (cylinder)
Step-by-step explanation:
Two circular bases which are parallel and congruent :
This basically means that the shape contains a circular base (supposedly the bottom), but since it has two bases, its on the top and the bottom. Because it's congruent, the bases are both equal in shape and size. It is also parallel as well, in which the bases have the same distance between them.
The cube doesn't have any circular bases.
The sphere doesn't have any faces, nor edges.
A cone has a circular base, but it doesn't have two.
A cylinder has two circular bases, as well as they are parallel and congruent.
So, your answer is B (cylinder).

A doctor advises a patient not to consume more than 8.5 × 10−2 kg of sugar per day. Coca cola
contains 110 g/L sugar. How many 12 oz cans of Coca cola can the patient consume? Show your work.
The patient can consume approximately 2 cans of 12 oz Coca Cola without exceeding the advised sugar limit.
To determine the number of 12 oz cans of Coca Cola the patient can consume, we need to convert the sugar limit provided by the doctor into grams and then calculate the amount of sugar in a 12 oz can of Coca Cola.
Provided:
Sugar limit: 8.5 × 10^(-2) kg
Coca Cola sugar content: 110 g/L
Volume of a 12 oz can: 12 oz (which is approximately 355 mL)
First, let's convert the sugar limit from kilograms to grams:
Sugar limit = 8.5 × 10^(-2) kg = 8.5 × 10^(-2) kg × 1000 g/kg = 85 g
Next, we need to calculate the amount of sugar in a 12 oz can of Coca Cola:
Volume of a 12 oz can = 355 mL = 355/1000 L = 0.355 L
Amount of sugar in a 12 oz can of Coca Cola = 110 g/L × 0.355 L = 39.05 g
Now, we can determine the number of cans the patient can consume by dividing the sugar limit by the amount of sugar in a can:
Number of cans = Sugar limit / Amount of sugar in a can
Number of cans = 85 g / 39.05 g ≈ 2.18
Since the number of cans cannot be fractional, the patient should limit their consumption to 2 cans of Coca Cola.

The following system of linear equations is shown in the graph.
y=1/4x+5
x-4y=4
How many solutions does the system of linear equations have?
A. No solution
B. Infinitely many solutions
C. One solution at (4,0)
D. One solution at (0,-1)
Answer:
Step-by-step explanation:
The slopes of both those lines are the same so there is no solution. Use slope triangles to find out the slope. They are both 1/4.
A. No solution
y = 1/4x+5
x - 4y = 4
You can simplify the second equation into y = 1/4x - 1
Since these equations both have the same slope, they are parallel. When two lines are parallel, they have no solutions.
Solve the equation

(4x − 24) + x = 14.
Answer:
To solve the equation (4x - 24) + x = 14, we can start by combining like terms on the left side of the equation:
4x - 24 + x = 14
Next we'll add the x terms together and the constants together:
5x - 24 = 14
Then we'll add 24 to both sides to get all the x terms on one side:
5x = 38
Finally we'll divide both sides by 5 to find the value of x:
x = 7.6
So the solution to the equation is x = 7.6

3. describe the pattern of learning math concepts according to siegler.
According to Siegler, the pattern of learning math concepts involves a gradual development and refinement of strategies. Siegler's theory, known as the overlapping waves model, suggests that learners use multiple strategies simultaneously and gradually shift towards more efficient ones over time. This process allows for a better understanding and application of math concepts, ultimately leading to improved problem-solving skills.
According to Siegler, the pattern of learning math concepts involves a gradual progression from using counting strategies to more efficient and accurate strategies. Children initially rely on counting strategies to solve math problems, such as counting fingers or objects. As they progress, they begin to use more advanced strategies, such as decomposition or mental math, which allow them to solve problems more quickly and accurately. Siegler also emphasizes the importance of practice and repetition in developing math skills and the role of feedback and instruction in promoting learning. Overall, Siegler's theory suggests that children's math skills develop through a combination of innate abilities and environmental factors, including exposure to math concepts and opportunities for practice and instruction in time.

The right question is;
A frame by frame analysis of a slowmotion video shows that a hovering dragonfly takes 6 frames to complete one wing beat.
If the video is shot at 190 frames per second, how many wing beats does the dragonfly perform per second?
On a number line, what is the distance between 6 and 6? between 24 and 17? between 17 and 24? between t and 4? This last question is harder to answer because it depends on whether t is smaller than or greater than 4. Is the answer t 4 or 4 t? This is an absolute value calculation: use absolute value signs to express the distance between t and 4. What is the distance between the numbers a and b on the number line? What is the relationship between |p q| and |q p|?
On a number line, the distance between any number and itself is always 0. Therefore, the distance between 6 and 6 is 0.
The distance between 24 and 17 can be calculated by subtracting the smaller number from the larger number, considering only the magnitude: |24 - 17| = 7.
Similarly, the distance between 17 and 24 can be calculated as |17 - 24| = 7. The absolute value ensures that the distance is always positive, regardless of the order of subtraction.
For the distance between a variable "t" and 4, the answer depends on the relationship between t and 4. If t is smaller than 4, the distance is expressed as |t - 4|. If t is greater than 4, the distance is expressed as |4 - t|. In either case, the absolute value ensures a positive value.
The distance between any numbers a and b on the number line can be calculated as |a - b|.
The relationship between |p - q| and |q - p| is that they are equal. The absolute value function disregards the sign of the argument, so whether you subtract p from q or q from p, the result will have the same magnitude. Therefore, |p - q| = |q - p|.

suppose we have dollars and each day we buy either milk (2$), juice (2$), coffee ($3) or cookies ($1) let be the number of ways of spending all the money. the recurrence relation for is:
The recurrence relation N(n) = N(n - 2) + N(n - 2) + N(n - 3) + N(n - 1) represents the number of ways to spend all the money when we have a certain amount of dollars and four options for spending it: milk, juice, coffee, and cookies.
Let's denote the number of ways of spending all the money as N(n), where n represents the amount of money we have. Our goal is to find the recurrence relation for N(n).
To start, let's consider the base cases. When n = 0, it means we have no money left. In this case, there is only one way to spend the money, and that is by not buying anything. Therefore, N(0) = 1.
Now, let's consider the cases when n > 0. We have four options for spending the money: milk, juice, coffee, and cookies. Let's analyze each option separately.
If we decide to buy milk, it costs $2. After buying milk, we are left with n - 2 dollars. We need to find the number of ways to spend the remaining money, which is N(n - 2).
Therefore, the number of ways of spending all the money when buying milk is equal to N(n - 2).
If we decide to buy juice, it also costs $2. After buying juice, we are left with n - 2 dollars. We need to find the number of ways to spend the remaining money, which is N(n - 2).
Therefore, the number of ways of spending all the money when buying juice is equal to N(n - 2).
If we decide to buy coffee, it costs $3. After buying coffee, we are left with n - 3 dollars. We need to find the number of ways to spend the remaining money, which is N(n - 3). Therefore, the number of ways of spending all the money when buying coffee is equal to N(n - 3).
If we decide to buy cookies, it costs $1. After buying cookies, we are left with n - 1 dollars. We need to find the number of ways to spend the remaining money, which is N(n - 1). Therefore, the number of ways of spending all the money when buying cookies is equal to N(n - 1).
Now, let's consider the total number of ways to spend all the money when considering all the options. Since each option is independent, we can add up the number of ways for each option. Therefore, the recurrence relation for N(n) can be expressed as:
N(n) = N(n - 2) + N(n - 2) + N(n - 3) + N(n - 1)
This recurrence relation allows us to compute the number of ways of spending all the money for any given amount of money. By using dynamic programming techniques, we can start with the base case N(0) = 1 and compute the values of N(n) iteratively until we reach the desired amount of money.

If sint=79, and t is in quadrant i, find the exact value of sin(2t), cos(2t), and tan(2t) algebraically without solving for t.
sin(2t) = 2(79)cos(t). cos(2t) = √(1 - 79^2) - 79^2. tan(2t) = (2(79)cos(t))/((√(1 - 79^2) - 79^2).
To find the exact value of sin(2t), cos(2t), and tan(2t) algebraically without solving for t, we can use trigonometric identities.
Let's start with sin(2t). By using the double-angle identity for sine, we have:
sin(2t) = 2sin(t)cos(t)
Since t is in quadrant I, both sin(t) and cos(t) are positive. Therefore, we can substitute sin(t) = 79 into the equation:
sin(2t) = 2(79)cos(t)
Moving on to cos(2t), we can use the double-angle identity for cosine:
cos(2t) = cos^2(t) - sin^2(t)
Substituting sin(t) = 79 and cos(t) = √(1 - sin^2(t)) = √(1 - 79^2) into the equation, we get:
cos(2t) = √(1 - 79^2) - 79^2
Finally, let's find tan(2t) using the identity:
tan(2t) = sin(2t)/cos(2t)
Substituting the values we found for sin(2t) and cos(2t):
tan(2t) = (2(79)cos(t))/((√(1 - 79^2) - 79^2)

Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
(-4,1) m=4
The equation of the line is ?
Answer:
An equation in point-slope form of the line that passes through the given point and with the given slope m = 4 will be:
\(y-1 = 4(x-(-4))\)
Step-by-step explanation:
Given
The point = (-4, 1)m = 4Using the point-slope form of the line equation
\(y-y_1=m\left(x-x_1\right)\)
here:
m = slope(x₁, y₁) = pointsubstituting the values m = 4 and the point (-4, 1) in the point-slope form of the line equation
\(y-y_1=m\left(x-x_1\right)\)
\(y-1 = 4(x-(-4))\)
Thus,
An equation in point-slope form of the line that passes through the given point and with the given slope m = 4 will be:
\(y-1 = 4(x-(-4))\)
Note: It can further be simplified
\(y-1=4\left(x+4\right)\)
Add 1 to both sides
\(y-1+1=4\left(x+4\right)+1\)
\(y=4x+17\)

The slope of the line below is -0.5. Enter the equation for the line in point-
slope form.
(1, 1)
The equation for the line in point-(1, 1) is y = -0.5x + 0.5.
Given that the slope of the line below is -0.5. We are to enter the equation for the line in point-(1, 1).The equation for the slope-intercept form of the line is y = mx + c where m is the slope and c is the y-intercept.
Now, the slope of the line is given as -0.5.Therefore, the equation for the slope-intercept form of the line is y = -0.5x + c. Now we need to find the value of c for the equation of the line.
To find the value of c, substitute the values of x and y in the equation of the slope-intercept form of the line.
Given that the point is (-1,1), x=-1 and y=1y = -0.5x + c⇒ 1 = (-0.5) (-1) + c⇒ 1 = 0.5 + c⇒ c = 1 - 0.5⇒ c = 0.5
Therefore, the equation for the line in point-(1, 1) is y = -0.5x + 0.5.The slope of a line refers to how steep the line is and is used to describe its direction. Slope is defined as the vertical change between two points divided by the horizontal change between them.A positive slope moves up and to the right, while a negative slope moves down and to the right. If a line has a slope of zero, it is said to be a horizontal line.
The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept, or the point at which the line crosses the y-axis. To find the equation of a line with a given slope and a point, we can use the point-slope form of a linear equation.
