In which place is the digit in the number 5,341 that would it be changed to 5,841 how to how do the values of two numbers compare
Answers
We get that, the digit is in the 3rd place (hundreds).The difference between the numbers is 500.
We want to change the digit in the number 5,341 into 5,841.
We also need to find the difference between the numbers.
The number 3 is in the 3rd place (hundreds) of the number 5,341 as a digit will be replaced by 8 to form the number 5,841.
This means that 300 is replaced by 800 because the third place in both the numbers is of hundreds.
The difference between 800 and 300 is:
800 - 300 = 500.
Subtraction of 5,341 from 5,841 also yields 500.
Therefore, we get that, the digit is in the 3rd place (hundreds).The difference between the numbers is 500.

The average of five numbers is 72, two of them are 70 and 74. Find the average of the other three numbers.
Answers
The average of the other 3 numbers is 72.
Average or mean is a measure of central tendency which calculates the central point of a data-set.
Average of a set of numbers is calculated by taking the sum of the numbers and dividing it by the total frequency of the numbers.
If 3 numbers a , b and c are taken then the average is equal to
(a+b+c) ÷3
Given average of 5 numbers is 72.
Therefore the sum of the numbers is 72 × 5 = 360
Two of the numbers are 70 and 74 .
Sum of the remaining 3 numbers = 360 - (70 + 74) = 360 - 144 = 216
Average of the 3 numbers = 216 ÷ 3 = 72
Therefore the average of the remaining 3 numbers is 72.

The independent variable: lengths of the sides
The dependent variable: the perimeter of a square,
K(5) = 20.
What is the Dependent and Independent variable of a Function?The dependent variable of a function is the output of a function that changes as a result of any change in the independent variable, which is the input of the function.
The input (independent variable) determines the output (dependent variable) of a function.
Therefore, we can make the following deductions:
The independent variable, x, represents lengths of the sides, and the dependent variable is the perimeter of a square, because the perimeter of the square depends on the length of the side of the square.
The function that relates to the variables is: K(x) = 4x
So, K(5) = 4(5) = 20.
This means, if 5 is the length of one of the sides of the square, then 20 is the perimeter of the square.

Estimate the quotient of 538 divided by 96 by using two methods 
Answers
The two methods for estimation of the quotient of 538 divided by 96 is being explained.
We are given that:
538 ÷ 96
We need to estimate the quotient of 538 ÷ 96 by using two methods.
The first method can be that we first estimate the divisor and the dividend to the nearest tens and then perform the division.
538 will be rounded off to 540 and 96 will be rounded off to 100.
So, it becomes:
540 ÷ 100
= 5.4
This will again be rounded off to 5
= 5
The second method will be that we first perform the division and then round off.
538 ÷ 96 = 5.61
Rounding off, we will get:
= 6.
Therefore the two methods for estimation of the quotient of 538 divided by 96 is being explained.

two sides of a right triangle measure 222 units and 444 units. 2\text{ units}2 units4\text{ units}4 units what is the area of the square that shares a side with the third side of the triangle?
Answers
With the help of Pythagoras Theorem for triangles, we get that the possible areas of the square are: 12 sq. units and 20 sq. units, according to the cases mentioned.
What is Pythagoras Theorem?According to the Pythagoras Theorem, in a right angled triangle, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Given:
Sides of a right triangle are 2 and 4 units.
To find: Area of a square that shares a side with the third side of the triangle.
Finding:
There can the following cases:
If 2 and 4 units are the lengths of the perpendicular sides.
Then, by Pythagoras Theorem, -
[tex]H^{2} = 2^{2}+4^{2}\\ H^{2} = Side^{2}\\H=Side \\H= \sqrt{4+16} \\H= \sqrt{20} \\H= 2\sqrt{5}[/tex]
Hence, the area of the square = side² = 20 units²
If 4 units is the length of hypotenuse.
Then, by Pythagoras Theorem,
[tex]4^{2} = 2^{2} + A^{2} \\16 - 4 = A^{2} \\= \sqrt{12}\\[/tex]
side of triangle = [tex]\sqrt{12}[/tex]
Hence, the area of the square = side² = 12 units²

Tom drives 8 1/2 miles every 1/30 hour. How many miles can he drive in 3 hours
Answers
In 3 hours Tom drives 243 miles.
What is speed?The rate at which an object's position changes in any direction. Speed is defined as the ratio of distance traveled to time spent traveling. Because it has only one direction and no magnitude, speed is a scalar quantity.So, to find how many miles Tom can drive in 3 hours:
Given: Tom drives 81/2 miles every 1/30 hour.
81/2 miles = 40.5 miles1/30 hours = 30 minutesSo, in 30 minutesTom drives 40.5 miles.
Then, in 1 hour Tom will drive 40.5 + 40.5 = 81 miles.Miles Tom will drive in 3 hours = 81 × 3 = 243 miles.Therefore, Tom drives 243 miles in 3 hours.

Answer:

Step-by-step explanation:
The picture is a little blurry so the graph is hard to read. But I believe the answer is 7/8. The rose would be counting up or down the y axis and the run is counting forward or backward on the x axis.
Hope this helps! :)
Answer:
rise = 7, run = 8
slope = rise/run = 7/8
See attached picture for graph in case you have to plot
Step-by-step explanation:
Take two distinguishable points, (x1, y1) and (x2, y2) on the graph. Find the difference in their y values= y2 - y1. This will be the rise
Find the corresponding difference in the x values, x2 - x1. This will be the run
Divide the y difference by the x difference and you get rise/run which is the slope of the line
Two clear points are (x1 = 0, y1= -7) and (x2=8, y2=0)
(y2 - y1)/(x2 - x1)
= (0 - (-7)/(8 - 0))
= (0+7/(8 - 0) ==> 2 negatives make a positive
= 7/8 and that is rise/run
Rise = 7, run = 8

2y + 20y - 15 = 19 + 20y Combine the left side.
22y - 15 = 19 + 20y Add 15 to both sides
22y - 15+15 = 19 +15 + 20y Combine
22y = 34 + 20y Subtract 20y from booth sides
22y-20y = 34 + 20y-20y Combine
