- Electricity City increases the price of televisions by 25%. If a television now sells for
$425, what was the original price?
Answers
Answer:
340
Step-by-step explanation:
Let x = original price
We increase by 25%
x+x*25% = new price
Change to decimal form
x+.25x = new price
Factor out the x
x(1+.25) = new price
x(1.25) = new price
x(1.25) = 425
Divide each side by 1.25
x = 425/1.25
x =340
The original price is 340

A rectangle is inside a circle with a 5 cm radius.
What is the area of the shaded region?
Use 3.14 for π .
Enter your answer as a decimal in the box.
cm²
The area of a rectangle with dimensions of 8 cm by 6 cm is removed from the area of a circle with a radius of 5 cm.
Answers
Answer: 30.5 cm²
To get the the area of the rectangle all we have to do is:
Rectangle Area = 6 × 8 = 48 cm²
Same thing to the circle, multiply the radius and pi:
Circle Area = 3.14 x 5² = 78.5 cm²
We have to subtract the two areas to find the shaded area.
78.5 - 48 = 30.5 cm²
I hope this helps!
Answer: 30.5 cm².

There are 9 children in a class who take the bus to school, and there are 15 total children in the class. What percentage of the children take the bus to school?
Answers
Answer:
60%
Step-by-step explanation:
(9/15)*100=60
The percentage of the children take the bus to school will be 60%.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
There are 9 children in a class who take the bus to school.
And, There are 15 total children in the class.
Now,
Since, Total children in class = 15
And, There are 9 children in a class who take the bus to school.
So, The percentage of the children take the bus to school will be calculated as;
Percent = (Children to take bus to school / Total children) x 100
= (9 / 15) x 100
= 60%
Thus, The percentage of the children take the bus to school will be 60%.

A flashlight battery manufacturer makes a model of battery whose mean shelf life is three years and four months, with a standard deviation of three months. The distribution is approximately normal. One production run of batteries in the factory was 25,000 batteries. How many of those batteries can be expected to last between three years and one month and three years and seven months?
Answers
Answer:
17000 batteries
Step-by-step explanation:
Three years and one month is equivalent to the mean minus one standard deviation.
Three years and seven months is equivalent to the mean plus one standard deviation.
For a normal distribution, we know that 68% of population is between mean ± 1 sd, then can be expected that 25000*68% = 17000 of batteries last between three years and one month and three years and seven months

At a certain time of day, the angle of elevation of the sun is 40°. To the nearest foot,find the height of a tree whose shadow is 35 feet long.
Answers
Explanation: You need to find a tree so that the angle of elevation from the end of the shadow to top of the tree is 40 degrees.
The length of the shadow is an adjacent side and is 35.
The height of the tree is the opposite side. You could use X.
Tan ratio = opposite/adjacent
tan(40) = x/35
x = 35*tan(40) =29.37

which function will add the same number each time
Answers
A linear function adds the same number each time. It has a constant rate of change which means it adds or subtracts a certain amount at each step. An example of this would be the equation y = 3x + 2.
Explanation:The function described in the question which will add the same number each time is called a linear function. In mathematics, a linear function is a function that has a constant rate of change. This means that it adds or subtracts the same amount each time. For example, the equation y = 3x + 2 is a linear function. Every time you increase x by 1, y will increase by 3. Similarly, each time you decrease x by 1, y will decrease by 3. This is because the slope of a linear function is constant, indicating a consistent rate of change.

How much energy would a 15,000 g block of ice need to absorb in order to
melt? The heat of fusion of ice is 333 J/g. Enter your answer to the nearest
whole number of kJ.
Answers
Answer:
The energy a 15,000 g block of ice will absorb in order to melt is 4995 kJ
Step-by-step explanation:
The question relates to the latent heat of fusion of ice, that is the heat absorbed by the solid ice to convert it to liquid water without changing its temperature.
The formula for the energy required to melt the ice is presented as follows;
Energy required = Mass, m × Latent heat of fusion, [tex]L_f[/tex], of ice
Hence, the mass, m, of the ice = 15,000 g
Latent heat of fusion, [tex]L_f[/tex], of ice = 333 J/g
Therefore;
Energy required = 15,000 g × 333 J/g = 4995000 J
Hence;
The energy a 15,000 g block of ice will absorb in order to melt = 4995000 J
1000 J = 1 kJ
1 J = 1/1000 kJ
Therefore, 4995000 J = (4995000 J)/(1000 J/kJ) = 4995 kJ.
Which gives;
The energy a 15,000 g block of ice will absorb in order to melt = 4995 kJ.

Write an equation of the line that passes through a pair of points: (negative 2, 2), (5, negative 5)
Answers
To find the equation of the line through (-2, 2) and (5, -5), calculate the slope which is -1 and then use the slope-intercept form to find the y-intercept, which is 0. The equation of the line is y = -x.
Explanation:To write an equation of the line that passes through the points (-2, 2) and (5, -5), you need to determine the slope and the y-intercept of the line. First, calculate the slope (m) which is the change in y divided by the change in x: m = (y2 - y1) / (x2 - x1).
Using the points (-2, 2) and (5, -5), the slope calculation would be: m = (-5 - 2) / (5 - (-2)) = (-7) / (7) = -1. This indicates that the line has a negative slope.
Next, use the slope-intercept form of a line, which is y = mx + b, where m is the slope and b is the y-intercept. To find b, use one of the given points and the slope you calculated: 2 = (-1)(-2) + b, which simplifies to 2 = 2 + b, and thus b = 0.
The equation of the line is therefore y = -1x + 0, which simplifies to y = -x.
