Light travels 3 x 10^5 kilometers in one second. How far does it travel in 6.7 seconds? Write your answer in scientific notation.

Answers

Answer 1

The distance covered by the traveling light in 6.7 seconds is 2.01 × 10⁶ kilometers.

What is the distance covered by the light in 6.7 seconds?

The speed formula is expressed as:

Speed = Distance / Time

Given the parameter:
Distance covered by the light = 3 × 10⁵ kilometers

Elapsed time = 1 second

Speed =?

The speed of the light is:

Speed = Distance / Time

Speed = 3 × 10⁵ kilometers / 1 second

Speed = 3 × 10⁵ kilometers per second

Now, we find the distance covered by the light in 6.7 seconds.

Speed = Distance / Time

Distance = Speed × Time

Distance = 3 × 10⁵ kilometers per second × 6.7 seconds

Distance = 2.01 × 10⁶ kilometers.

Therefore, the distance traveled is 2.01 × 10⁶ kilometers.

Liam’s football team scored a total of 43 separate times this season, with a mix of touchdowns and field goals. Each touchdown is worth 7 points, and each field goal is worth 3 points. If the team scored a total of 301 points this season, how many touchdowns and field goals did they score?

Answers

This question is an example of what we call "system of equations". We can use two separate equations to help us solve.

Let a = number of touchdowns
Let b = number of field goals

a + b = 43
7a + 3b = 301

We can solve this system using the elimination method.

1. a + b - b = 43 + -b (add - b to both sides)
a = -b + 43

2. substitute -b + 43 for a in 7a + 3b = 301
7 (-b +43) + 3b = 301
-4b + 301 = 301 (simplify both sides of the equation)
-4b + 301 - 301 = 301 - 301 (add -301 to both sides)
-4b = 0
b = 0

Since b = 0, and b is the number of field goals, we know that Liam's team did not score any field goals. Which means the only points from his team came from touchdowns. So, 43 touchdowns were scored, and 0 field goals were scored, for a total of 301 points.

Final answer:

The football team scored 43 times this season, comprising solely of touchdowns worth 7 points each, totalling to 301 points. The team did not score any field goals worth 3 points.

Explanation:

This problem can be solved using systems of linear equations. We have two equations here: 1. The total number of times the team scored, which is touchdowns(T) plus field goals(F) equals 43 (T+F=43). 2. The total points the team made, each touchdown being 7 points and each field goal being 3 points, equals 301 (7T + 3F = 301). By solving this system of equations, we can find the number of touchdowns and field goals.

From the first equation (T + F = 43), we can express T as (43 - F). Substitute T in the second equation: 7(43 - F) + 3F = 301, which simplifies to 301 = 301 - 4F. By rearranging, we get 4F = 0. Hence, F = 0. Returning to the first equation, T = 43 - F. As F=0, T = 43.

Thus, the team scored 43 touchdowns and 0 field goals.

Answers

That would be too little chlorine compared to safety standarts:
10,000 gallons of water is 5 times more than 2,000. So to achieve the safety standards , Park's pool must have 5 times the amount of chlorine it's necessary for 2.000 gallons.
3 chlorine tablets × 5 = 15 tablets

Mark would need to put 15 chlorine tablets to achieve safety standards

I hope you understood my brief explanation . And please consider marking this awnser as Branliest. Thank you! :)

Answer:

In the park's pool there are 7 less chlorine tablets as compared to safety standards.

Step-by-step explanation:

Number of chlorine tablets in 2,000 gallons water = 3 tablets

Number of tablets in 1 gallon of water = [tex]\frac{3}{2,000} tablets[/tex]

Number of tablet to be added in 10,000 gallons of water :

[tex]\frac{3}{2,000}\times 10,000 tablets=15 tablets[/tex]

Number of chlorine tablets added by lifeguard in 10,000 gallon water=8 tablets

Tablets of chlorine to be more added =

=15 tablets - 8 tablets = 7 tablets

In the park's pool there are 7 less chlorine tablets as compared to safety standards.

Jimmy invest $16,000 in an account that pays 7.03% compounded quarterly. How long (in years and months) will it take for his investment to reach $23,000?

Answers

To solve this we are going to use the compound interest formula [tex]A=P(1+ \frac{r}{n})^{nt} [/tex]
where:
[tex]P[/tex] is the investment
[tex]r[/tex] is the interest rate in decimal form
[tex]n[/tex] is the number of times the interest is compounded per year
[tex]t[/tex] is the time in years
[tex]A[/tex] is the amount after [tex]t[/tex] years

First, lets convert the interest rate to decimal dividing it by 100%:
[tex]r= \frac{7.03}{100} =0.0703[/tex]
Next, lets find [tex]n[/tex]. Since we know that the interest is compounded every 4 months (quarterly), it will be compounded [tex] \frac{12}{4} =3[/tex] times in a year, so [tex]n=4[/tex].
We also know that [tex]A=23000[/tex] and [tex]P=16000[/tex], so lets replace all the quantities into our compound interest formula:
[tex]25000=16000(1+ \frac{0.0703}{3})^{3t} [/tex]
[tex]25000=16000(1.0234)^{3t} [/tex]

Notice that the the number of years [tex]t[/tex] is in the exponent, so we have to use logarithms to bring it down. But first lets divide both sides by 16000 to isolate the exponential expression:
[tex] \frac{25000}{16000} =(1.0234)^{3t} [/tex]
[tex](1.0234)^{3t} = \frac{25}{16} [/tex]
[tex]ln(1.0234)^{3t} =ln( \frac{25}{16} )[/tex]
[tex]t= \frac{ln( \frac{25}{16}) }{3ln(1.0234)} [/tex]
[tex]t=6.43[/tex]

Now that we know [tex]t=6.43[/tex], the last thing to do is convert 0.43 years to months:
[tex](0.43 years)( \frac{12months}{1year} )=5.16months[/tex]

We can conclude that Jimmy's investment will take 6 years and 5 months to reach $25,000.

1. You have to find the area of the rectangle and then add it to the area of the traingle. So you'd have 6×3 for the rectangle, added to ((15-3)÷2)×(6+6) for the triangle. So the overall area would be 18+72 which is 90.

2. Once again you just have to find the areas of the individual shapes and then add them together. So, 8×4 added to (4+4)×4 added to 12×12. So the area would be 32+32+144 which is 208.

3. First work out the triangles area: (12-8)×((16-10)/2) which equals 12. And then add it to the rectangles area: 16×8 which is 128. So the area is 140.

4. Find out the area of the circles: 3.14×1.5^2 which is 7.065. This is the area for a full circle and as there is 4 halves in the picture, multiply this number by 2, giving a total circle area of 14.13. Then simply add the square area which is 3×3. So the total area is 23.13.

It's the same for the last two. Seperate 5 into a triangle, long rectangle down the bottom and a squarish one up top. Work out the individual areas for these three shapes and then just add them.

For 6 just work out the semicircle, rectangle and triangle areas and add them once more.

Cut the figure into a rectangle and triangle. You are left with a rectangle with length 6 and width 3, and a triangle with base 15 - 3 = 12 and height 6 + 6 = 12.

A = lw

A = (6)(3)

A = 18 ft^2

So the area of the rectangle is 18 square feet.

A = 1/2bh

A = 1/2(12)(12)

A = 72 ft^2

So the area of the triangle is 72 square feet. Add the two areas together to find the total area of the figure:

18 + 72 = 90 ft^2

So the area of the figure is 90 square feet.

The population of Ashmore was 925 in 2000 and 1028 in 2001. The linear model of Ashmore's population is p=103t+925, where t is the years since 2000.
Find an exponential model, in the form P=a(b)t, for Ashmore's population t-years after 2000. Round b to the nearest thousandth.

Answers

Final answer:

To find the exponential model for Ashmore's population, rewrite the linear model as p = a(b)^t and solve for a and b. In this case, a is equal to 925 and b is approximately 1.111.

Explanation:

To find the exponential model for Ashmore's population, we need to express it in the form P = a(b)^t. We know that in the linear model, p = 103t + 925. To convert this to an exponential model, we need to rewrite it in the form p = a(b)^t. To do this, we need to find the values of a and b.

From the linear model, we can see that when t = 0 (in the year 2000), p = 925. This gives us the equation 925 = a(b)^0. Since any number raised to the power of 0 is 1, we can simplify this equation to a = 925.

Next, we need to find the value of b. We can do this by substituting the given values of p and t from the year 2001 (p = 1028 and t = 1) into the exponential model. This gives us the equation 1028 = 925(b)^1. Dividing both sides by 925, we get b ≈ 1.11.

Therefore, the exponential model for Ashmore's population is P = 925(1.11)^t. Rounded to the nearest thousandth, b ≈ 1.111.

Final answer:

The exponential model for the population of Ashmore t years after 2000 is P=925(1.111)^t, where a is the initial population 925, and b is the growth rate rounded to the nearest thousandth, which is 1.111.

Explanation:

To find an exponential model for Ashmore's population in the form P=a(b)^t, where P is the population t years after 2000, we need to use the given data points: 925 in 2000 and 1028 in 2001.

First, let's establish our initial population a as the population at t=0, which is 925. Now we need to find the growth rate b. Since the population in 2001 is 1028, we have one growth period, which is t=1. We can write the equation for 2001 as 1028 = 925b. Dividing both sides by 925 gives us b = 1028 / 925 ≈ 1.111.

For simplicity and to follow instructions, we will round b to the nearest thousandth, giving us b ≈ 1.111. Therefore, the exponential model is P=925(1.111)^t.

The result of the experiment is displayed in the box plot below.

Secure hike emergency radio 4.0 21,22,24,25,25,25,25,26,27,29,30,30,30,30,33

Streamline radio 25,25,27,28,29,30,30,30,34,36,36,38,39,42

A. 50% of streamline crank radios are likely to play 30 minutes or longer after 30 cranks, while only 25% of secure hike emergency radios ARE LIKELY to play 30 minutes or longer after 30 cranks.

B. 75% of secure hike emergency radios ARE LIKELY to play 30 minutes or longer after 30 cranks, while only 50% of streamline crank radios ARE LIKELY to play 30 minutes or longer after 30 cranks.

C. 100%of x- streamline crank radios ARE LIKELY to play 30 minutes or longer after 30 cranks, while only 25% of secure hike radios ARE LIKELY to play 30 minutes or longer after 30 cranks.

2times 2 1/3 as a mixed number

Answers

the answer is 14/3 or 4 2/3.
2 1/3 = 2 x 3 + 1 all over 3 = 7/3
2 x 7/3 = 2 x 7 / 1 x 3 = 14/3 = 4 2/3

The answer would be

First turn the mixed number into a fraction, which is 7/3
We need to turn 2 into a fraction, so we put it over a 1, so 2/1.

Now we multiply and simplify , which is 14/3

Which gives us a mixed number of 4 2/3

Hope this helped, have fun and STAY SMART! =P

chris are 1/8 of a banana cream pie with a 1/4 diameter. what is the area of the remaining portion of the pie
plz show work

Answers

To find the remaining area of the pie, you will need to find the area of the original pie and then multiply it by 7/8 because that is the amount of the pie that was NOT eaten.

Here is the formula to find the area:
A = pi x r^2
22/7 x 1/8^2
A = 11/224 square units is the area.

7/8 x 11/224 = 11/256 square units is the area of the original pie.

Answer:153.9

Step-by-step explanations equation A=pi×r^2

A=pi×7^2

A=pi×79

A=153.9 i round

A solid has 14 faces and 12 vertices. How many edges does the solid have

Answers

Number of faces + (Number of vertices - Number of edges) = 2
14 + (12 - x) = 2
12 - x = 2 - 14
12 - x = - 12
- x = -12 - 12
-x = - 24
x = 24

There would be 24 edges.

Giving brainiest to the most accurate answer. (please include your work)

Answers

Answer:

C is the answer. C= 4,464in squared.

Step-by-step explanation:

All you would have to do is multiply all the numbers together and then choose your answer

Rebecca needs 4,464 square inches of wrapping paper to completely cover the boxes.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Each box has six sides, and the dimensions of each side are:

12 x 10, 12 x 10, 12 x 3, 12 x 3, 10 x 3, and 10 x 3 inches.

The total surface area of each box is:

2(12 x 10) + 2(12 x 3) + 2(10 x 3) = 240 + 72 + 60

= 372 square inches.

Since there are 12 boxes, the total surface area of all the boxes is:

= 12 x 372

= 4,464 square inches.

Therefore,

Rebecca needs 4,464 square inches of wrapping paper to completely cover the boxes.
