What is rounding off the numbers?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.
A number can be rounded off to its lower value if the number after the decimal is between 0 and 4. The number will be rounded off to its higher value if the number after it is between 5 and 9.
Given decimal number is 4.624. The rounding off is:-
4.624 = 4.6 at 10 places
Therefore, the value of the decimal number 4.624 to the nearest 10 places is 4.6

Problem page a light bulb consumes 2400 watt-hours per day. how many watt-hours does it consume in 3 days and 6 hours?
Final answer:
The light bulb consumes 7800 watt-hours in 3 days and 6 hours, calculated by summing the daily consumption over three days and additional energy consumed in 6 hours.
Explanation:
To calculate the energy consumption in watt-hours, we first understand that the light bulb consumes 2400 watt-hours in one day. To find out how much it consumes in 3 days and 6 hours, we multiply the daily consumption by the number of days and then add the consumption for the additional 6 hours:
Energy consumed in 3 days = 2400 watt-hours/day imes 3 days = 7200 watt-hours
Energy consumed in 6 hours = (2400 watt-hours/day) / (24 hours/day) imes 6 hours = 600 watt-hours
Adding these two amounts gives us the total energy consumption in the specified time:
Total energy consumption = 7200 watt-hours + 600 watt-hours = 7800 watt-hours
Therefore, the light bulb consumes 7800 watt-hours in 3 days and 6 hours.

Which expression will produce a positive product:
(-12)(12)(-6.3)(-0.2)(-15.9)
(12)(-6.3)(-0.2)(-15.9
(-12)(12)(-6.3)(-0.2)(-15.9)(0)
(12)(12)(6.3)(0.2)(-15.9)
Final answer:
To produce a positive product, the expression (12)(-6.3)(-0.2)(-15.9) should be used.
Explanation:
To determine which expression will produce a positive product, we need to consider the sign rules for multiplication.
If we have an even number of negative signs within a set of parentheses, the product will be positive. If we have an odd number of negative signs, the product will be negative.
Let's analyze the given expressions:
(-12)(12)(-6.3)(-0.2)(-15.9): This expression has five negative signs, which means it will produce a negative product.(12)(-6.3)(-0.2)(-15.9): This expression has four negative signs, which means it will produce a positive product.(-12)(12)(-6.3)(-0.2)(-15.9)(0): This expression includes a 0, and any product multiplied by 0 will be 0, which is neither positive nor negative.(12)(12)(6.3)(0.2)(-15.9): This expression has one negative sign, which means it will produce a negative product.Therefore, the expression (12)(-6.3)(-0.2)(-15.9) will produce a positive product.
The expression that will produce a positive product is (12)(-6.3)(-0.2)(-15.9) because it contains an even number of negative signs, which results in a positive product according to the rules of multiplication regarding signs.
Explanation:To find which expression will produce a positive product, we must recall the rules of multiplication regarding signs:
When two positive numbers multiply, the result is positive (e.g., 2x3 = 6).When two negative numbers multiply, the result is also positive (e.g., (-4) x (-3) = 12).When multiply numbers with opposite signs, the result is negative (e.g., (-3) x 2 = -6 and 4 x (-4) = -16).When any number is multiplied by zero, the result is always zero.We can now evaluate the expressions given:
(-12)(12)(-6.3)(-0.2)(-15.9): This expression has an odd number of negative signs, so the product is negative.(12)(-6.3)(-0.2)(-15.9): This has an even number of negative signs, making the product positive.(-12)(12)(-6.3)(-0.2)(-15.9)(0): The presence of a zero means the product is zero.(12)(12)(6.3)(0.2)(-15.9): This has one negative sign, so the product is negative.The correct expression that will produce a positive product is (12)(-6.3)(-0.2)(-15.9).
If a line has a positive slope what is its general direction
A line with a positive slope generally moves upward from left to right, representing an increase in y-values as x-values rise.
Explanation:If a line has a positive slope, its general direction is upward from left to right. This means that as the x-values increase, the y-values also increase. The slope of a line in mathematics represents the rate at which y changes with respect to x. A positive slope indicates a direct relationship between the two variables involved; as one increases, so does the other. In the context of a graph, this manifests as a line that rises as it moves along the x-axis.
The nature of the slope determines the line's direction. A higher positive slope indicates a steeper ascent, while a smaller positive slope results in a less steep, flatter incline. The concept of slope is crucial in economics as well, as it measures the relationship between two variables, such as price and quantity supplied, where a positive slope illustrates that firms supply more as the price goes higher.

Mrs evans has 120 crayons and 30 pieces of paper to give to her students. what is the largest number of students she can have so that each student gets equal number of crayons and equal number of pieces of paper
The maximum number of students that will receive the paper and crayons are 30.
What is ratio?
Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
Given is Mrs. Evans who has 120 crayons and 30 pieces of paper to give to her students.
We have 120 crayons and 30 pieces of paper.
Then for 1 paper, we will have (120/30) which is equivalent to 4 crayons.
So, every student will get 1 paper and 4 crayons.
Assume that the maximum number of students that will receive the paper and crayons are [x]. Then, we can write -
x + 4x = 120 + 30
5x = 150
5x = 150
x = 30
Therefore, the maximum number of students that will receive the paper and crayons are 30.

Given: 2(10−13)=−34+60
Step 1: Distribute
20−26 = −34+60
Step 2: Addition Property of Equality
−26 = −34+80
Step 3: Addition Property of Equality
8=80
Step 4: Division Property of Equality
=10
Answer:
error in step 2. 20 is added on both sides instead of subtraction.
Step-by-step explanation:
Given: [tex]2(10-13)=-34+60[/tex]
Step 1: Distribute
[tex]20-26 = -34+60[/tex]
2 is distributed inside the parenthesis. 2 times 10 is 20
2 times -13 is -26
Step 2: Addition Property of Equality
[tex]-26 = -34+80[/tex]
To eliminate 20 we subtract 20 from both sides. Here 20 is added on both sides. To eliminate any number we do opposite operation. So there is an error in this step.
Step 3: Addition Property of Equality
8=80
Step 4: Division Property of Equality

3. Find the slope of the segments AB, CD, and EF.
AB =

Answer:
1) AB=7 CD=3 EF=[tex]3\sqrt{5}[/tex] 2) [tex]M_{AB}=\frac{-1}{2},2[/tex] [tex] \\ M_{EF} =(\frac{5}{2}-3)[/tex] \\ [tex] \\ M_{EF} =(\frac{5}{2}-3)[/tex] 3) AB not inclined CD not inclined EF 6/5
Step-by-step explanation:
1) We can use the Distance Formula to answer the 1st. question.
But in the first case AB I'd rather doing it intuitively because it is a straight line parallel to the x-axis
AB
A(-4,2) and B(3,2)
In this segment, also parallel we can calculate the length as |-4|+|3|=7 since both have the same y coordinate.
Using the Distance formula to check it:
[tex]D=\sqrt{(3--4)^{2}+(2-2)^{2}}\\D=\sqrt{49}\\D=7[/tex]
CD
C(-4,-1) D(-4,-4)
Similar to the first one but this time with different y coordinates.
The length will be calculated by subtracting the absolute values for y:
|-4|-|-1|=4-1 = 3
Using the Distance formula to check it:
[tex]D=\sqrt{(-4--1)^{2}+(-4--4)^{2}}\\D=\sqrt{9}\\D=3[/tex]
EF
E (1,-1) F(4,-5)
In this case there's no straight line.
So right to the Distance Formula:
[tex]D=\sqrt{(-5-1)^{2}+(4-1)^{2}}\\ D=\sqrt{36+9}\\D=\sqrt{45}\\D=3\sqrt{5}[/tex]
2) To find the Midpoints we need to calculate the Mean of these two points.
AB
A(-4,2) and B(3,2)
[tex]M_{AB} =\frac{-4+3}{2},\frac{2+2}{2}\\M_{AB}=\frac{-1}{2},2[/tex]
CD
C(-4,-1) D(-4,-4)
[tex]M_{CD} =\frac{-4-4}{2} ,\frac{-1-4}{2} \\M_{CD} =(0,\frac{-5}{2})[/tex]
EF
E (1,-1) F(4,-5)
[tex]M_{EF} =\frac{4+1}{2} ,\frac{-1-5}{2} \\ M_{EF} =(\frac{5}{2}-3)[/tex]
3) To find the Slope let's calculate the quotient of a difference between y-coordinates over x-coordinates of two given points.
[tex]m_{AB}=\frac{2-2}{3--4}=\frac{0}{7}=0[/tex]
AB is not inclined.
CD
C(-4,-1) D(-4,-4)
[tex]m_{CD}=\frac{-4--1}{-4--4}=\frac{-3}{-4+4}=\frac{-3}{0}[/tex]
Not Defined for all Real Set of Numbers
The line CD is not inclined.
EF
E(1,-1) F(4,-5)
[tex]m_{EF}=\frac{-5-1}{4--1}=\frac{6}{5}[/tex]
The line EF has a slope of 6/5
