The equation given as 2/(7 - m) = 4/(m - 5) - m/(7 -m) has no real solution for m
How to determine the solution set to the equation?The equation is given as
2/(7 - m) = 4/(m - 5) - m/(7 -m)
Take the like terms of the above equation
So, we have
m/(7 -m) + 2/(7 - m) = 4/(m - 5)
Evaluate the like terms in the above equation
So, we have
(m + 2)/(7 -m) = 4/(m - 5)
Cross multiply the above equation
So, we have
m^2 + 2m - 5m - 10 = 28 - 4m
Evaluate the like terms
m^2 + m + 18 = 0
Using a graphing tool, we have no solution for m
Hence, the equation given as 2/(7 - m) = 4/(m - 5) - m/(7 -m) has no real solution for m

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.

A bucket of paint has spilled on a tile floor. The paint flow can be expressed with the
function p(t) = 6t, where t represents time in minutes and p represents how far the paint is
spreading.
The flowing paint is creating a circular pattern on the tile. The area of the pattern can be
expressed as A(p) = лp².
Part A: Find the area of the circle of spilled paint as a function of time, or A[p(t)]. Show your
work. (6 points)
Part B: How large is the area of spilled paint after 8 minutes? You may use 3.14 to
approximate in this problem. (4 points)
Answer:
Part A: 28.26t²
Part B: 2,826 square unit
Explanation:
Part A:
A[p(t)] = π (3t)² = 3.14 * 9t² = 28.26t²
Part B:
p(10) = 3(10) = 30
A(p) = 3.14 * 30² = 3.14 * 900 = 2,826 square unit

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]

a number is chosen at random from the positive, even integers from 2 to 50. find the probability that the number chosen is divisible by 5 or 8.
The probability that the number chosen is dividible by 5 or 8 is 0.306.
According to the given question.
A number is chosen at random from the positive even integers from 2 to 50.
Now the total positive intergers from 2 to 50 which are divisible by 5 or 8 are {5, 8, 10, 15, 16, 20, 24, 25,30, 32, 35, 40, 45, 48, 50}
So, there are total 15 positive intergers from 2 to 50 which are divisible by 5 or 8.
⇒ Total number of favourable outcomes = 15
And the total positive integers from 2 and 50 is 49.
⇒ Total number of outcomes is 49.
As we know that, proabability is calculated by taking the ratio of favourable outcomes to the total number of outcomes.
Therefore, the probability that the number chosen is divisible by 5 or 8
= 15/49
= 0.306
Hence, the probability that the number chosen is dividible by 5 or 8 is 0.306.

following describes the best decision for Larry?
The option that describes the best decision for Larry is Larry buys the second lawn mower because he thinks the extra $5 are worth not having to do the assembly.
How much does Larry spend?The cost of the first lawnmower after the discount is:
= 275 x (1 - 20%)
= 275 x 0.80
= $220
The cost of the second lawnmower is:

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:

find the rise and the run
Answer:
down below
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

Initially, there were only 3 weeds at a park. The weeds grew at a rate of 5% each week. The following function represents the weekly weed growth: f(x) = 3(1.05)x. Rewrite the function to show how quickly the weeds grow each day and calculate this rate as a percentage.
f(x) = 3(1.007)7x; spreads at a rate of approximately 0.7% daily
f(x) = 3(1.05)7x; spreads at a rate of approximately 0.5% daily
f(x) = 3(0.15)x; spreads at a rate of approximately 0.15% daily
f(x) = 3(1.007)x; spreads at a rate of approximately 0.07% daily
Based on the calculation below, the rate at which the weeds grow each day is 0.7%.
How do we calculate the daily percentage growth rate?Given:
f(x) = 3(1.05)x = 3(1 + 0.05)x ................... (1)
Since there are 7 days in a week, the rate at which the weeds grow each day can be calculated from equation (1) by dividing 0.05 (i.e. 5% weekly growth rate) as follows:
f(x) = 3(1 + (0.05 / 7))x
f(x) = 3(1 + 0.007)x
f(x) = 3(1.007)x
Since 0.007 is the same as 0.7%, this implies that the rate at which the weeds grow each day is 0.7%.
The correct option is "f(x) = 3(1.007)7x; spreads at a rate of approximately 0.7% daily".

False
• Correlation means that there is a relationship or patter between the two variables. A scatter plot displays the data about the two variables as a set of points in the x-y plane and it is a useful tool for determining if there is a correlation between the variables.
• Causation means the one event causes other event to occur. It can only be determined by designed experiment.
• While correlation and causation both can exist at the same time, correlation doesn’t imply causation.
• Causation explicitly applies only to cases where action P causes outcome Q whereas correlation is simply a relationship.
Correlation doesn’t prove causation.
There could be third variable associated with the size of engine which caused the truck to have greater horsepower. For example, it can be that manufacturers anticipate that consumers who wanted trucks with greater horsepower also prefered trucks with larger engines and therefore chooses to make trucks with larger horsepower.

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
