We get that the cost of the battery is $ 8.24 per battery.
We are given that the cost of 88 batteries = $ 724.72
We need to find the cost of one battery.
We will do this by diving the cost of 88 batteries by 88.
Using division, we get that:
cost of one battery = $ 724.72 ÷ 88
Simplifying the expression, we get that:
cost of one battery = $ 8.24 per battery.
Therefore, we get that the cost of the battery is $ 8.24 per battery.

Laine reads 200 pages in 240 minutes.
If Laine reads 25 pages at the same rate, how long will it take her?
Laine will take 30 minutes to read 25 pages.
Given Laine reads 200 pages in 240 minutes.
We need to find the time taken to read 25 pages, if Laine reads at the same rate.
First, let us find out the time taken to read one page.
240 minutes are taken to read 200 pages
This implies that the time taken to read 1 page = 240/200 minutes
This implies that the time taken to read 1 page = 6/5 minutes
Therefore, the time taken for 25 pages = 25 ×(6/5) minutes
⇒ The time taken for 25 pages = 30 minutes
Hence, Laine will read 25 pages in 30 minutes, if she reads 200 pages in 240 minutes.

Calculate the magnitude of the repulsive force between a +500μC charge and a +100μC charge which are 5 m apart. [k=9×109 Nm2C-1]
The magnitude of the repulsive force between a +500μC charge and a +100μC charge which are 5 m apart is 2N.
The repulsive force between two charges = (k q₁ q₂)/r²
q₁ q₂ are the charges
r is distance between the charges
k= 9×10⁹ Nm²C²
F= (500μC) (+100μC)9×10⁹/25
= 2N
A movement between two charges that are same or comparable is referred to as repulsion. The tension between two electrons (negative charge). Two charges of a different sort are drawn toward one another by the force of attraction, which is defined as "a force between two charges that are distinct or different."
At a distance, magnetism is an attractive or repulsive force. The repulsive force gives rise to a metric that measures how a system's gravitational mass changes. According to the force-based approach, the forces that attract and repel other atoms come from their subatomic arrangement and control how they behave.

Solve the system of equations and choose the correct ordered pair. y=-2x+4 y=x-2
Answer:
(-6, -8)
Step-by-step explanation:
We have the following system of equations:
[tex]y = 2x+4[/tex] (1)
and
[tex]y=x-2[/tex] (2)
Set (1) = (2) since the LHS is y in both
We get
[tex]2x + 4 = x - 2[/tex]
Subtract x from both sides:
[tex]2x + 4 - x = x - 2 -x[/tex]
[tex]x + 4 = -2[/tex]
Subtract 4 from both sides
[tex]x + 4 - 4 = -2 -4[/tex]
[tex]x = -6[/tex]
Substitute for x in Equation (2) to get
[tex]y = -6 - 2 = -8[/tex]
So the solution is (-6, -8)

a) James have to invest 5,248 dollar and 89 cent to earn $7,592 amount of interest in 16 years .
b) Principal amount of money , which is to be invested is 4158 dollar and 46 cent .
This is a problem from simple interest system. We have to use the given formula, I = p.r.t to solve this problem.
a) James wants to have earned $7,592 amount of interest in 16 years. So, here the time period is 16 years and the interest rate is 9.04% and we have to find the principal amount.
I = p. 16. ( 9.04% )
Amount of interest = $ 7592
Time period = 16 years
rate of interest = 9.04 %
7592 = p . 16 . ( 904/10000 )
p = 75920000/ 16 . 904
or , p = $5,248.89 ≈ $5249
James have to invest $5,248.89 to earn $7,592 amount of interest in 16 years .
b) We have to use the given formula to find the value of p or the principal amount of money .
Rate of interest = 8.63% or .0863
time period = 24 years
Interest = $8613
We can write ,
p = I / r.t

Some students estimated that a small block of Copper will have the mass = 500 g
Estimated mass = 500 g
But now, the actual mass was found out and it came = 428 g
Actual mass = 428 g
The error in estimation was:
Error = 500 g - 428 g
Error = 72 g
Percentage of error = 72 g / 428 g × 100
Percentage of error = 7200 g / 428 g %
Percentage of error = 16.82 %

The area of the given figure is 70 square units, that is, option 3.
The area of a rectangle = length × breadth
Here, we need to find the area of the shaded region.
To do this, we will subtract the area of the smaller rectangle from the larger one.
The area of the larger rectangle = 8 × 15
= 120 square units
Now, the we have one side of the smaller rectangle which is 5, the other side will be (15 - 4 - 1) = 10 units.
The area of the smaller rectangle = 10 × 5

by using inductive reasoning, we get the next 2 terms as 7 / 12 and 4 / 7.
We are given a sequence:
3 / 4, 2 / 3, 5 / 8, 3 / 5
We need to find the next two terms by using the inductive reasoning.
Now, we can also write this sequence as:
3 / 4, 4 / 6, 5 / 8, 6 / 10
Now, we can see that, in each term, the numerator is increasing by 1 and the denominator is increasing by 2 units.
So, the 5th term will be:
Numerator = 6+ 1 = 7
Denominator = 10 + 2 = 12
5th term = 7 / 12
And the 6th term will be:
Numerator = 7 + 1 = 8
Denominator = 12 + 2 = 14
6th term = 8 / 14 = 4 / 7
Therefore, by using inductive reasoning, we get the next 2 terms as 7 / 12 and 4 / 7.

A passenger in an airplane at an altitude of 10 kilometers sees two towns directly to the east of the plane. The angles of depression to the towns are 24° and 53° (see figure). How far (in km) apart are the towns? (Round your answer to one decimal place.)
Using relations in a right triangle, it is found that the distance between the towns is of 15 km.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.For the first town, we have that:
The internal angle of the triangle 90 - 53 = 37º.The opposite side to the angle is the horizontal position xA.The adjacent side to the angle is of 10 km.Hence:
tan(37º) = xA/10
xA = 10 x tan(37º).
xA = 7.5 km.
For the second town, we have that:
The internal angle of the triangle 90 - 24 = 66º.The opposite side to the angle is the horizontal position xB.The adjacent side to the angle is of 10 km.Hence:
tan(66º) = xB/10
xB = 10 x tan(66º).
xB = 22.5 km.
Hence the distance is:
22.5 km - 7.5 km = 15 km.

For the rational function f(x)=2−x4x+6, find the point on the graph at the function value f(x)=1.
The point on the graph at the function value f(x)=1 is x = -4/5
How to find the point on the graph at the function value f(x)=1?The equation of the function is given as:
f(x) = 2 - x4x + 6
Rewrite the rational function, properly as follows:
f(x) = 2 - x/4x + 6
When f(x) = 1, we have:
2 - x/4x + 6 = 1
Cross multiply
2 - x = 4x + 6
Collect the like terms
4x + x = 2 - 6
Evaluate the like terms
5x = -4
