The solution to given equation (3/4)x + 3 - 2x = -(1/4) + (1/2)x + 5
is x = -1
Consider given equation.
(3/4)x + 3 - 2x = -(1/4) + (1/2)x + 5
We need to solve this equation.
First we combine the like terms on each side of the equation.
(3/4 - 2)x + 3 = (-1/4 + 5) + (1/2)x
Simplify each side of the above equation.
(-5/4)x + 3 = 19/4 + (1/2)x
Now subtract (1/2)x from each side,
(-5/4)x + 3 - (1/2)x = 19/4 + (1/2)x - (1/2)x
Simplify each side
(-5/4 - 1/2)x + 3 = 19/4 + 0
(-7/4)x + 3 = 19/4
Add -3 to each side of the equation.
(-7/4)x + 3 - 3= 19/4 - 3
(-7/4)x = 7/4
Multiply each side of equation by (-4/7)
(-7/4)x × (-4/7) = 7/4 × (-4/7)
x = -1
Therefore, the solution is x = -1

two fair dice are thrown together. what is the probability that the difference between the two outcomes is 3
The probability of getting a difference of 3 when two fair dice are thrown together is 1/9.
What is probability?Probability is the measure of how likely it is that a certain event will occur. It is expressed as a number between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain. Probability can also be expressed as a percentage or fraction. Probability is used to describe the likelihood of an event occurring, and its calculation is based on the number of possible outcomes of the event.
This is due to the fact that there are 6 possible outcomes for each dice, and 36 possible outcomes when both dice are thrown. The only way to get a difference of 3 is for the first dice to show a 4 (1/6 probability) and the second dice to show a 1 (also 1/6 probability). This gives a combined probability of 1/6 x 1/6 = 1/36, which is 1/9.

A restaurant uses square tables with sides of length 1.3 m and round tablecloths with diameter 2 m determine the percentage of each tablecloth which overhangs its Table
Answer:
The tablecloth overhang is the amount of tablecloth that hangs over the edges of the table.
The area of the square table is 1.3m * 1.3m = 1.69m^2.
The area of the round tablecloth is pi * (diameter/2)^2 = pi * (2/2)^2 = pi * 1^2 = pi * 1 = pi m^2.
The overhang is the difference between the area of the round tablecloth and the square table.
Overhang = pi m^2 - 1.69m^2 = pi - 1.69
To find the percentage of the tablecloth that overhangs the table, we can divide the overhang by the area of the tablecloth and multiply by 100.
Overhang % = (pi - 1.69) / pi * 100 = (pi - 1.69) / pi * 100 = (3.14 - 1.69) / 3.14 * 100 = 1.45 / 3.14 * 100 = 46.14%.
So, the percentage of the tablecloth that overhangs the table is 46.14%.

The right option is Option C: y = 5x + 1
The given line passes through the points (5,0) and (0,1).
The slope of the line is found by:
[tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
This implies that,
[tex]m = \frac{1-0}{0-5} \\m = \frac{-1}{5}[/tex]
The product of the slope of the two perpendicular lines should be negative one.
Thus,
[tex]m_{1} * m_{2} = -1[/tex]
This implies that,
[tex]\frac{-1}{5} * m_{2} = -1[/tex]
Giving us, m2 = 5
We can use the slope intercept formula,
y = mx + b
where b = 1 is the y-value of the y-intercept.
The equation thus becomes,

while traveling to europe, phelan exchanged 250 us dollars for euros. he spent 150 euros on his trip. after returning to the united states he converts his money back to us dollars. how much of the original 250 us dollars does phelan now have? round to the nearest cent. 1 european euro
Phelan now has 81.48 x 1.08 = 87.79 US dollars, which is 87.79 dollars of the original 250 dollars.
First, we need to find out how many euros Phelan has left after spending 150 euros on his trip.
We are taking the exchange rate of 1 euro = 1.08 USD
He started with 250 US dollars, which he exchanged for 250 / 1.08 = 231.48 euros.
After spending 150 euros, he has 231.48 - 150 = 81.48 euros left.
To convert the euros back to US dollars, we need to multiply the number of euros by the exchange rate (1 US dollar = 1.08 euros)
So, Phelan now has 81.48 x 1.08 = 87.79 US dollars, which is 87.79 dollars of the original 250 dollars.

We'll now obtain an estimate of the area of this region with a Riemann Sum, i.e. a collection of rectangles whose combined area approximates the area under the region. On your graph, slice the area up into 4 pieces by drawing 3 evenly spaced vertical lines from the x-axis up to the curve. Then using the left side of each slice as the height, sketch in 4 rectangles on your graph; these four rectangles should overlay the region under 1/x between 1 and 2. What are the x-coordinates of the left edges of the rectangles
The x-coordinates of the left edges of the rectangles are 1,5/4,6/4,7/4.
The area of this region with a Riemann Sum is 0.7595.
What does Riemann sum mean?A specific type of approximation of an integral by a finite sum in mathematics is known as a Riemann sum. It bears the name of the German mathematician Bernhard Riemann from the nineteenth century. Approximating the area of functions or lines on a graph, as well as the length of curves and other approximations, is a highly typical use.
Given function is f(x) = 1/x on the interval [1,2] is shown.
The four rectangles of width 1/4 are present.
From the figure we can see that the x coordinate of the left edges of the rectangle are:
1,5/4,6/4,7/4
Now we plug these values in the function to find the height of rectangles.
For x=1 ,f(x) = 1
For x=5/4 ,f(x) = 4/5
For x=6/4 ,f(x) = 4/6
For x=7/4 ,f(x) = 4/7
Now, Area = length*width, and width of each rectangle is 1/4
Area of rectangle 1 = 1*1/4 = 1/4
Area of rectangle 2 = 4/5*1/4 = 1/5
Area of rectangle 3 = 4/6*1/4 = 1/6
Area of rectangle 4 = 4/7*1/4 = 1/7
Total Area is = 1/4+1/5+1/6+1/7 = 0.7595

a bus traveled at 25 miles per hour (mi/h) for 10 miles in town, then 45 miles per hour for 17 miles on a rural highway, then 80 miles per hour for 95 miles on and interstate freeway, and, finally, a slow 12 miles per hour for 4 miles in a crowded city before coming to the bus stop. what was the average speed of the bus?
The average speed of the bus is 54.78 mph.
To find the average speed of the bus, we need to find the total distance traveled and the total time taken for the entire trip.
Distance traveled = 10 miles + 17 miles + 95 miles + 4 miles = 126 miles
To find the total time taken, we need to calculate the time taken for each segment of the trip and add them up.
Time taken for 10 miles at 25 mi/h = 10 miles / 25 mi/h = 0.4 hours
Time taken for 17 miles at 45 mi/h = 17 miles / 45 mi/h = 0.378 hours
Time taken for 95 miles at 80 mi/h = 95 miles / 80 mi/h = 1.1875 hours
Time taken for 4 miles at 12 mi/h = 4 miles / 12 mi/h = 0.333 hours
Total time taken = 0.4 hours + 0.378 hours + 1.1875 hours + 0.333 hours = 2.3 hours
Average speed = total distance / total time = 126 miles / 2.3 hours = 54.78 mph
So, the average speed of the bus is 54.78 mph.

The complete question is as follows:
a spherical ball 8 inches in diameter is coated with a layer of ice of uniform thickness. if the ice melts at a rate of 10 cubic inches per min, how fast is the thickness of the ice decreasing when it is 2 inches thick? at the same rate of melting, how fast is the outer surface area of the ice changing?
The surface area of the ice is 16π square inches. At a rate of 10 cubic inches per min, the outer surface area of the ice is changing at 10/16π square inches per min.
To calculate this we have given:
The diameter of the spherical ball is 8 inches, so the radius of the ball is 8/2 = 4 inches.
The volume of a sphere is given by the formula (4/3)πr³, where r is the radius of the sphere.
The volume of the spherical ball with 2 inches of ice is (4/3)π(4³) = (4/3)π64 cubic inches.
The volume of the ice is the volume of the spherical ball with 2 inches of ice minus the volume of the spherical ball without the ice, which is (4/3)π(4³) - (4/3)π(4³ - (2³)) = (4/3)π64 - (4/3)π32 = 32π cubic inches
At a rate of 10 cubic inches per min, the thickness of the ice is decreasing at:
10 cubic inches / 32π cubic inches = 10/32π inches per min
To find the rate at which the outer surface area of the ice is changing, we can use the formula for the surface area of a sphere which is 4πr².
The surface area of the ice is 4π(4-2)³ = 4π4 = 16π square inches.
At a rate of 10 cubic inches per min, the outer surface area of the ice is changing at:
10 cubic inches / 16π square inches = 10/16π square inches per min

A taxi charges a base fee of $3. 00 and $0. 15 for every mile of the ride. What would be the cost of a 3. 4 mile ride?
Someone please help me on this…
The cost of a 3.4 mile ride when a taxi charges a base fee of $3.00 and $0.15 for every mile of the ride is $3.51.
Therefore the answer is $3.51
The cost of a 3.4 mile ride can be calculated by multiplying the distance of the ride by the cost per mile and adding the base fee. Here base fee is the fixed charge and $0.15 is the variable charge that depend on distance covered.
To calculate the cost of the ride:

[tex]x=\frac{118}{360}(2)(3)(\pi) \approx 6.2[/tex]
For many years businesses have struggled with the rising cost of health care. But recently, the increases have slowed due to less inflation in health care prices and employees paying for a larger portion of health care benefits. A recent Mercer survey showed that of U.S. employers were likely to require higher employee contributions for health care coverage in 2009. Suppose the survey was based on a sample of companies.
Therefore, 0.4854 to 0.5546 is the 95% confidence range for the percentage of businesses that are anticipated to need greater employee payments for health insurance coverage in 2009.
A. Computation the margin of error
First step is to calculate the Confidence level using this formula
Confidence level= 1 -α
Where,
α=0.95
Let's enter the formula.
Level of confidence = 1-0.95
Level of confidence = 0.05
The following step is to use this formula to get Z.
Zα/2
Let's enter the formula.
Z= 0.05/2
Z=0.025
Finding the Z score of Z=0.025 is the third stage.
Zα/2=1.96
Let's now use this approach to calculating the margin of error.
Margin of error=Zα/2√p(1-p)/n
Where,
Zα/2=1.96
p=0.52
n=800
Let plug in the formula
Margin of error=1.96√0.52(1-0.52)/800
Margin of error=1.96√0.52(0.48)/800
Margin of error=1.96√0.2496/800
Margin of error=1.96√0.000312
Margin of error=0.0346
Therefore Margin of error will be 0.0346
B. Calculating the proportion of businesses anticipated to demand greater employee payments for health insurance coverage in 2009 with a 95% confidence interval
computation for the confidence interval's outer limits
p- Zα/2√p(1-p)/n
Where,
Zα/2=1.96
p=0.52
n=800
Let plug in the formula
Confidence interval=0.52-1.96√0.52(1-0.52)/800
Confidence interval=0.52-1.96√0.52(0.48)/800
Confidence interval=0.52-1.96√0.2496/800
Confidence interval=-0.52-1.96√0.000312
Confidence interval=0.4854
Computation for the boundaries of confidence interval
Using this formula
p+ Zα/2√p(1-p)/n
Where,
Zα/2=1.96
p=0.52
n=800
Let plug in the formula
Confidence interval=0.52+1.96√0.52(1-0.52)/800
Confidence interval=0.52+1.96√0.52(0.48)/800
Confidence interval=0.52+1.96√0.2496/800
Confidence interval=-0.52+1.96√0.000312
Confidence interval=0.5546
