A camper lights an oil lantern at 12 noon and lets it burn continuously. Once the lantern is lit, the lantern burns oil at a constant rate each hour. At 2 p.m., the amount of oil left in
the lantern is 63 ounces. At 5 p.m., the amount of oil left in the lantern is 61 ounces.
Based on the average rate of oil burning per hour, how much oil, in ounces, was in the lantern at 12 noon? Show your work.

Answers

5 because from 2 - 5 it burned 3 ounces an ounce per hour

Answer:

64.33 ounces

Step-by-step explanation: The rate at which the oil burns.

1 hour = 2/3 ounce

At 2 pm = 63 ounces

At 5 pm = 61 ounces

The amount of oil at 12 noon is 64.33 ounces.

Juanita and Stephanie went to a clearance sale at a clothing store. Juanita bought 4 blouses and 3 skirts for a total of $ 72 . Stephanie bought 6 blouses and 3 skirts for a total of $ 96 . If all blouses cost the same and all skirts cost the same, then, what was the cost of each blouse and each skirt?

Answers

4b+3s=72
6b+3s=96
Multiply the second equation by -1
-6b-3s=-96
Now you can cross out the +3s -3s
-2b=-24
Divide both sides by -2
b=12
s=8
So blouses cost $12 each and skirts cost $8 each

The system of equations has an infinite number of solutions as the two lines are coincident.

What are equations with infinite solutions?

An equation can have infinitely many solutions when it should satisfy some conditions. The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. If the two lines have the same y-intercept and slope, they are actually in the same line.

Given here the system of equations are: x+3y=0

12y=-4xor x+3y=0

thus both the equations are identical also their coefficients 1/1 = 3/3 so we can deduce the two lines are coincident with each other and therefore have infinite solutions.

Hence, The system of equations has an infinite number of solutions as the two lines are coincident.

What is 5x - 43 plz I can’t find out what it is

Answers

Answer:

x = 8.6

Simplifying

5x + -43 = 0

Reorder the terms:

-43 + 5x = 0

Solving

-43 + 5x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '43' to each side of the equation.

-43 + 43 + 5x = 0 + 43

Combine like terms: -43 + 43 = 0

0 + 5x = 0 + 43

5x = 0 + 43

Combine like terms: 0 + 43 = 43

5x = 43

Divide each side by '5'.

x = 8.6

Simplifying

x = 8.6

Step-by-step explanation:

Hope it is helpful...

x = 8.6

how many liters of water does a pipe with a diameter of 10cm left out, if water flows at the rate of 1.5m / sec and 3 minutes have passed?

Answers

Step-by-step explanation:

To find out how many liters of water flows through a pipe with a diameter of 10 cm when water flows at the rate of 1.5 m/s and 3 minutes have passed, you need to follow the steps below:

Step 1: Find the area of the pipe.

Area = πr² = π(5cm)² = 78.54 cm².Step 2: Convert the flow rate into cm³/s.

Flow rate = 1.5 m/s = 150 cm/s

Volume = Area × velocity = 78.54 × 150 = 11781 cm³/s.Step 3: Find the volume of water that flows through the pipe in 3 minutes.

Time = 3 minutes = 180 seconds

Volume = Flow rate × time = 11781 × 180 = 2,120,580 cm³.Step 4: Convert the volume into liters.

1 liter = 1000 cm³

Volume in liters = 2,120,580 cm³ ÷ 1000 = 2120.58 liters.Therefore, approximately 2120.58 liters of water flow through the pipe with a diameter of 10 cm when water flows at the rate of 1.5 m/s and 3 minutes have passed.

2120.58 liters approximately

How to define a linear function?

The slope-intercept representation of a linear function is given by the equation presented as follows:

y = mx + b

The coefficients of the function and their meaning are described as follows:

m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.

The slope and the intercept for the function in this problem are given as follows:

Slope of -1.22, meaning that for an increase of one degree Fahrenheit, the predicted decrease in the cost is of $1.22.Intercept of 96.2, meaning that the predicted heating cost for a month with temperature of 0 ºF is of $96.20.

Hence, the predicted cost for a month with temperature of 25ºF is given as follows:

y = -1.22(25) + 96.20 = $65.70.

Pamphlets Added to the box(x) Effect on the Box's Weight (y) 0 0 1 6 2 12 3 18 Is this an example of continuous or discrete data? discrete continuous

Answers

Answer:

This example represents discrete data.

Step-by-step explanation:

Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.

In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.

Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

This is an example of discrete data

Brainlist for positive attitude and correct answer :D

Answers

Answer: The correct answer is:

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D
