Answer 1
Adding integers is something to pick up since you will use it in all math. So for this problem we have 3 electrons which are negative (-red dots) and we have 3 protons which are positive (+ blue dots). When we add them this happens:

Proton + electrons = ?
3+ (-3)=0

0 is neutral, meaning not negative or positive so that means your lithium atom has neutral charge.

If you had a number line and you put your finger on 3 you would move 3 spaces left towards the negative numbers because 3 is negative and it would land you at 0.

On a certain spring day with 12 hours of daylight, the light intensity I takes on its largest value of 610 calories/cm^2 at midday. If t = 0 corresponds to sunrise, find a formula I = a sin bt, where t is in hours and a is in calories/cm2, that fits this information.

Answers

The sin bt can only take values between one and zero (definition of sin)The maximum of sin bt must be on at 1, when the maximum value of I occurs. Divide l = 610 by 1 to get a = 610.

If sin bt is equal to 1, the inverse sin will give us a value of bt = 90 degrees ( the value will be different from radians, bt = 1.57). assume the midday is the halfway point of the 12 hours of daylight, t = 90/6 = 15.
Therefore l = 610 sin 15 t where t is hours after sunrise.

what is the factors of 10

Answers

Answer: 1, 2, 5, and 10

Step-by-step explanation: To find the factors of 10, begin by dividing 10 by 1 which gives us 10. This tells us that 1 and 10 are factors of 10. Next, divide 10 by 2 which gives us 5. This tells us that 2 and 5 are also factors of 10. Next, divide 10 by 3. Notice that 10 doesn't divide evenly by 3 so 3 is not a factor of 10. Next, divide 10 by 4. Since 10 doesn't divide evenly by 4, then 4 is not a factor of 10. Next, divide 10 by 5 which gives us 2. This tells us that 5 and 2 are factors of 10 but notice that we already know that 5 and 2 are factors of 10. This means that 5 and 2 are repeat factors.

There is no need to repeat factors that we already know. In fact, as we are writing the factors of a number, it's important to understand that once we hit repeat factors, all other factors that we try will also repeat.

So here, dividing by anything greater than 5 will give us factors that we already know so we can stop here.

This means that the factors of 10 are 1, 2, 5, and 10.

the distance from the earth to the Sun is approximately 9.3×10^7 miles. if light travels 1.2×10^7 miles in 1 minute, how many minutes does it take the light from the sun to reach the earth ?

Answers

t takes 5 1/3 minutes for light from the sun to reach earth. The Moon is closer to earth, so it,s light reaches earth faster about 5 19/60 minutes faster than from the sun. How long does light from the moon take to reach earth.
Final answer:

It takes approximately 12.47 minutes for light from the Sun to reach the Earth.

Explanation:

To find out how many minutes it takes for light from the Sun to reach the Earth, we can divide the distance from the Earth to the Sun by the distance light travels in 1 minute.

First, let's convert the distance from miles to kilometers. 1 mile is approximately 1.60934 kilometers, so the distance from the Earth to the Sun is approximately 1.496 × 108 kilometers.

Now, we divide this distance by the distance light travels in 1 minute: 1.496 × 108 kilometers / 1.2 × 107 kilometers per minute = 12.47 minutes.

Therefore, it takes approximately 12.47 minutes for light from the Sun to reach the Earth.

b = 120

answer
C 120 

Answer:

The correct option is C. 120°

Step-by-step explanation:

For better explanation of the answer see the attached figure :

Since, Angle formed at the center is equal to the angle measure of its opposite arc

⇒ ∠AOD = 104°

Also, The angle formed in the segment is half the angle formed at the center of the circle

⇒ ∠DOB = 2 × ∠BAD

⇒ ∠DOB = 2 × 68°

⇒ ∠DOB = 136°

Now, ∠AOB = 360 - ∠BOD + ∠AOD

⇒ ∠AOB = 360 - 136 - 104

⇒ ∠AOB = 120°

Now, Angle formed at the center is equal to the angle measure of its opposite arc

⇒ b = ∠AOB

⇒ b = 101°

Hence, the correct option is C. 120°

The shanghai maglev train is one of the fastest trains in the world, traveling about 2144 miles in 8 hours. How many miles does it travel in one hour? The distance between columbus ohio and new york city is about 560 miles.how many hours would it take the train to travel between the cities

Answers

2144miles ÷ 8hrs = 268miles in 1hrs

trip 560 miles ÷ 268 miles per hours = 2hrs and 8min

Answer:

The train travels 268 miles in 1 hour. It would take 2.0896 hours to travel between the cities.

Step-by-step explanation:

Consider the provided information.

The shanghai maglev traveling about 2144 miles in 8 hours.

This can be written as:

2144 miles = 8 hours

Divide both sides by 8.

2144/8 miles = 8/8 hours

268 miles = 1 hours

Thus, the train travels 268 miles in 1 hour.

The distance between Columbus Ohio and new York city is about 560 miles. We need to find how many hours would it take the train to travel between the cities.

268 miles = 1 hours

Divide both the sides by 268.

1 miles = 1/268 hours

Now multiply both sides by 560.

560 miles = 560/268 hours

560 miles = 2.0896 hours

Hence, it would take 2.0896 hours to travel between the cities.

A wheel has 22 spokes evenly distributed around the rim of the wheel. What is the measure, in radians, of the central angle formed by adjacent pairs of spokes?

Answers

so a circle has a total amount of 2π radians, now, divided even in 22 pieces, like the picture below, then   [tex]\bf \cfrac{2\pi }{22}\implies \cfrac{\pi }{11}[/tex]
Final answer:

To find the radian measure between adjacent spokes of a wheel, you divide 2π by the number of spokes. In this case, the wheel has 22 spokes, leading to a radian measure of approximately 0.286 radians for the angle between adjacent spokes.

Explanation:

The topic of the question pertains to geometry and radian measures. In a full circle, there are 2π radians. If a wheel has 22 spokes, each spoke defines a section of the circle equally. So, you would divide 2π by 22 to determine the measure, in radians, of the central angle formed by adjacent pairs of spokes.

Step-by-step calculation: The formula for calculating this is 2π/n, where n is the number of sections (or spokes). Therefore, the radian measurement of the angle between adjacent spokes would be 2π/22 = 0.286 radians when rounded up.

The depth finder on a fishing boat gives readings that are within 5% of the actual water depth. when the depth finder reading is 250 feet, the actual water depth x lies within a range given by an inequality.

Answers

A range refers to the least and greatest amount with respect of a certain number. In this case, the number referred to is the actual water depth, denoted as x. The general equation would be:

Depth finder reading = Actual Water Depth +/- 0.05*Actual Water Depth
250 ft = x +/- 0.05x
250 ft = x(1 +/- 0.05)
x = 250/(1 +/- 0.05)

Solving the equation:
x = 250(1 + 0.05) = 262.5 ft
x = 250(1 - 0.05) = 237.5 ft

Hence, the actual depth is between the range 262.5 ft - 237.5 ft.

An executive invests $23,000, some at 8% and the rest at 7% annual interest. If he receives an annual return of $1,800, how much is invested at each rate

Answers

Final answer:

To solve this problem, we can set up an equation using the amount invested at each rate. Solving the equation will give us the amount invested at 8% and 7%.

Explanation:

To solve this problem, let's assume that the amount invested at 8% is x dollars. Therefore, the amount invested at 7% would be (23000 - x) dollars. Now we can set up an equation to represent the given information:

0.08x + 0.07(23000 - x) = 1800

Solving this equation will give us the amount invested at each rate.

0.08x + 0.07(23000 - x) = 1800

0.08x + 1610 - 0.07x = 1800

0.01x = 1800 - 1610

0.01x = 190

x = 190 / 0.01

x = 19000

Therefore, $19000 is invested at 8% and $4000 (23000 - 19000) is invested at 7%.

Final answer:

To solve the problem, set up a system of equations using x and y as variables to represent the amounts invested at 8% and 7%. Solve the system to find x and y. The amount invested at 8% is $19,000 and the amount invested at 7% is $4,000.

Explanation:

To solve this problem, we can set up a system of equations. Let x represent the amount invested at 8% and y represent the amount invested at 7%. The total amount invested is $23,000, so we have the equation x + y = 23,000. The total return is $1,800, so we have the equation 0.08x + 0.07y = 1,800. We can solve this system of equations to find the values of x and y.

By substitution, we can solve for x:

x + y = 23,000

x = 23,000 - y

Substituting this into the second equation:

0.08(23,000 - y) + 0.07y = 1,800

1,840 - 0.08y + 0.07y = 1,800

-0.01y = -40

y = 4,000

Substituting the value of y back into the first equation, we can find x:

x + 4,000 = 23,000

x = 19,000

So, $19,000 was invested at 8% and $4,000 was invested at 7%.

Roger sells fire trucks and dolls to a toy store. He sells each fire truck for $15 and each doll for $10. Roger wants to sell at least 25 toys and needs to earn at least $300 to cover his costs. If each fire truck takes 50 minutes to make and each doll takes 45 minutes to make, how many fire trucks and dolls should Roger make to minimize the time spent making the toys.

Answers

Answer:

this is the correct answer for plato (Roger should make 10 fire trucks and 15 dolls in order to minimize the time spent making toys.)

Step-by-step explanation:


Answer:

Number of Fire trucks made= 10.

Number of Dolls made =   15  

Step-by-step explanation:

Let x denote the number of fire trucks made.

and y denote the number of dolls made.

Now we are given:

Roger wants to sell at least 25 toys .

Hence, the inequality that can be made  from this information is:

                       [tex]x+y\geq 25[/tex]

Also,

He sells each fire truck for $15 and each doll for $10.

He needs to earn at least $300 to cover his costs.

The inequality that can be made from this piece of information is:

                 [tex]15x+10y\geq 300[/tex]

           Also,

                      x≥0

                 and y≥0

Each fire truck takes 50 minutes to make and each doll takes 45 minutes to make.

Now we are asked to minimize the time function let it denote by 'z'.

Hence, the system that is formed is:

Optimization function       Min.   z=50x+45y

    subject to                     x+y ≥ 25[/tex]

                                and   15x+10y ≥ 300[/tex]

Non-negative constraint         x ≥ 0

                                                 y ≥ 0

Now on solving the constraints we get the boundary points as:

(25,0) , (0,30) and (10,15)

Hence, the optimal solution is checked at these points.

(25,0)             z=1250

(0,30)            z=1350

(10,15)             z=1175

Hence, the minimal time spent is: 1175 minutes.

Number of Fire trucks made= 10.

Number of Dolls made =15

Identify which shapes are similar to shape A and which are not.

Answers

Similar figures have the same angles and sides of equal proportion.

By similarity,

I can see that shapes 2 and 3 is similar to shape A.
Shapes 1, 4, 5 and 6 is not similar to shape A.
Final answer:

To determine which shapes are similar to shape A, we must evaluate the pattern, repetition, and geometrical structure, while understanding the differences in geometrical and organic forms.

Explanation:

When identifying shapes similar to shape A, we must look at the pattern and repetition of the figures while noting the differences. Shapes that are similar will have proportionally equivalent angles and sides, despite potential differences in size. We analyze the given shapes by comparing their properties such as angles, sides, and overall geometrical structure.

In a more complex composition, identifying positive and negative shapes can be challenging due to the presence of implied shapes that are created by the arrangement of other shapes or colors around them. Therefore, an in-depth inspection is needed to determine similarity.

Lastly, it is necessary to understand that shapes can be geometric, like circles and squares, or organic, which are more freeform and less regular. When comparing shapes to shape A, recall that similar shapes must relate in the ways mentioned, despite their geometric or organic nature.
