When a flash of lightning occurs, the number of seconds elapsed until thunder is heard can be used to approximate the distance from the storm. The graph models this situation. Which equation can be used to approximate the distance from a storm, y , in miles, given the number of seconds, x , that has elapsed from the moment that a flash of lightning is seen to the time thunder is heard?

When A Flash Of Lightning Occurs, The Number Of Seconds Elapsed Until Thunder Is Heard Can Be Used To

Answers

Answer 1
Pretty sure its C :)
Answer 2
After you see a flash of lightning, count the number of seconds until you hear the thunder. (Use the stop watch or count "One-Mississippi, Two-Mississippi, Three-Mississippi," etc.) For every 5 seconds the storm is one mile away. Divide the number of seconds you count by 5 to get the number of miles.

Anitha and Jyothi shared some money. Anitha had $4x and Jyothi had $(2x + 8).
Both of them had $56 altogether. Find the value of x and hence find out how much
did Jyothi get?

Answers

Answer:

$24

Step-by-step explanation:

To begin we need to form an equation that equals the total amount of money, which is 56. The question tells us that Anitha's money and Jyothi's money comes to a sum of $56 (the total amount). So, in our equation we will be doing Anitha + Jyothi = 56; our equation will be 4x+2x+8=56.

The next step is to rearrange the equation to get x=..., and we can do this using the funnel method like I have shown in the attached image. First, I simplified to get 6x+8=56. Then, I subtracted 8 from both sides to get 6x=48. Finally, I divided by 6 on both sides to get x=8. This is the first step of the question completed.

The finish the question, we need to work out Jyothi's total money, and since we now know x=8, all we need to do is substitute 8 where x is for Jyothi. So, we need to calculate the answer to 2*8+8, and following the rules of BIDMAS, we get 24. Which is the final answer.

ATQ
4x + 2x + 8 = 56
6x + 8 = 56
6x = 56- 8
6x= 48
x = 48/6
x = 8

Jyothi = 2x + 8 = 2 x 8+8= $24

The rabbit population in a certain area is 500% of last​ year's population. There are 1,300 rabbits this year. How many were there last​ year?

Answers

There were 260 rabbits last year.

We know that last year was the original population as 100%. The population is now 5 times higher, as 100% x 5 is 500%.

To find the original rabbit population, we would then divide this years population of 1300 by 5, to get 1/5 aka 100% of the population. This number is 260

500/100=5
1300/5=260
260 rabbits hope this helps

Zachary purchased a computer for $1,600 on a payment plan. Two months after he purchased the computer, his balance was $1,370. Four months after he purchased the computer, his balance was $1,140. What is an equation that models the balance y after x months?

Answers

Answer:

Step-by-step explanation:

You are finding out each time how much is the items Zachary bought.

Then inputting a equation

$1,600 - ??? = $1,370

To find the unknown number, you must subtract the 2 original numbers.

$1,600 - $1,370 = $230

Computer costs: $230 leaving Zachary with $1,370 left.

Next, it says he purchased another computer...

$1,370 - ??? = $1,140

Again, we subtract the 2 original numbers to find the unknown.

$1,370 - $1,140 = $230 leaving Zachary with  $1,140 left.

Now we input this data into an equation...

y = -230x + 1600.

The chemistry teacher set out a 5 pound jar of salt at the beginning of the day. If each student needs 27.6 grams of salt for an experiment, how many students can perform the experiment before the jar is empty? (hint: 1lb=454grams)

Answers

Answer:

82 students

Step-by-step explanation:

In this, the first thing you should do is convert the five pounds to grams, which is 2270 grams. Now, all you need to divide 2270 by 27.6 to get the number of students because each student uses 27.6 grams and there 2270 grams being set each day. This gives you 82.2463768116 technically, but you should just round up, and that gives you 82 students. I hope this helped :D

Approximately 82 students can perform the experiment before the 5-pound jar of salt is empty.

In order to determine how many students can perform the experiment with the given jar of salt, we need to convert the jar's weight from pounds to grams, and then divide that by the amount of salt each student requires.

1. Given data: 1 pound = 454 grams (conversion factor).

2. The jar's weight is 5 pounds, so we multiply 5 by 454 to find the total grams of salt initially present in the jar:  

  5 pounds × 454 grams/pound = 2270 grams.

3. Each student needs 27.6 grams of salt for the experiment.

4. To find the number of students that can perform the experiment, we divide the total grams of salt by the grams per student:  

  Number of students = Total grams of salt / Grams per student.  

  Number of students = 2270 grams / 27.6 grams/student ≈ 82.42 students.

5. Since we can't have a fraction of a student, we round down to the nearest whole student (as we can't have a fraction of a student), yielding about 82 students.

6. However, we should also consider that after 82 students, there will be some salt left, but not enough for a complete experiment. Therefore, let's find out how much salt would be left after 82 students.

7. Salt used by 82 students = 82 students × 27.6 grams/student = 2263.2 grams.

8. Salt left in the jar = Total initial salt - Salt used by 82 students = 2270 grams - 2263.2 grams = 6.8 grams.

9. Since the remaining 6.8 grams is not sufficient for another complete experiment, we can conclude that approximately 82 students can perform the experiment before the jar is empty.

In conclusion, about 82 students can perform the experiment using the given 5-pound jar of salt.

Make an equation that has the numbers : -3.78 , -1.2y, and -4.2y

Answers

Answer: In solution

Step-by-step explanation:

Well, first you need to arrange the numbers in anyway, separated by operations. I just did:

-3.78 + (-1.2y + -4.2y)

We then need to come up with the other side of the equation.

For this, I added the like terms:

-3.78 + (-1.2y + -4.2y) = -3.78 -5.4y

Then, I came up with a value for y. Y = 5

Then, I multiplied -5.4 by 5, getting -27 so,

-3.78 + (-1.2y + -4.2y) = -3.78 - 27

Again, I collected like terms:

-3.78 + (-1.2y + -4.2y) = -30.78

Now, I have my equation.

———————————————————————————————

HOW TO SOLVE THE EQUATION

-3.78 + (-1.2y + -4.2y) = -30.78

1. Add 3.78 to both sides

-1.2y + -4.2y = -27

2. Collect like terms

-5.4y = -27

3. Divide both side by -5.4

y = 5

Answer:-

-3.75 + -1.2y = -4.2y

Step-by-step explanation:

the answer would then be that y= 1.26 when solved
