Eduardo counted 10 seconds between seeing lightning and hearing thunder, and he knew that the lightning was about 2 miles away. If he counted four seconds between the next flash of lightning and hearing thunder, about how far away was the lightning
Answers
Eduardo used the time difference between seeing lightning and hearing thunder to determine the distance of the lightning. Given that sound travels a mile every five seconds, the second lightning was 0.8 miles away, based on a time difference of 4 seconds.
Explanation:Eduardo is using a method to measure the distance of lightning by noting the time difference between the visible flash of light and the audible sound of thunder. The speed of light is much faster than the speed of sound, which is why we see lightning before we hear thunder. This method works because it is known that sound travels approximately one mile every five seconds.
So, in Eduardo's first observation, he counted 10 seconds between seeing the lightning and hearing thunder. Given that sound travels a mile every five seconds, the lightning was 10 seconds/5 = 2 miles away.
In the second observation, he counted four seconds between the flash and the thunder. Using the same calculation, this means the lightning was 4 seconds/5 = .8 miles away. This is in agreement with the given information.

Answer:
0.00018 and 1.8 × 10-4
Step-by-step explanation:
Jenna calculated several numbers in her calculator. The result displayed 1.8E-4 on the calculator screen.
1.8E^-4 means there are 3 zeroes after decimal then 18. When a value is very less than zero then the calculator shows that in E form. When we move the decimal to the left, it adds 1 to our exponent.
So, the correct answers are :
0.00018 and 1.8 × 10-4
1.8 × 10-4 = [tex]\frac{1.8}{10000}= 0.00018[/tex]
30. The perimeter of a rectangle is 292 feet. The length of the rectangle is 4 feet less than 5 times the width. What is the length and width of the rectangle? a. length = 121, width = 25b. length = 114.3, width = 23.7 c. length = 25, width = 121d. length = 121.7, width = 24.3
Answers
P = 292
L = 5W - 4
292 = 2(5W - 4 + W)
292 = 2(6W - 4)
292 = 12W - 8
292 + 8 = 12W
300 = 12W
300/12 = W
25 = W <=== width is 25 ft
L = 5W - 4
L = 5(25) - 4
L = 125 - 4
L = 121 <=== length is 121 ft

b. #tasks per hour =
#of tasks × time takes to do task < or = 60
n × 6.25 = 60
6.25n = 60.
n= 60/6.25 = 9.6
robot can complete 9 tasks in one hour
Answer:
A robot can complete 8 tasks in hour = [tex]\frac{5}{6}[/tex]
A robot can complete 1 task in hour = [tex]\frac{\frac{5}{6}}{8}[/tex]
A robot can complete 1 task in hour = [tex]\frac{5}{48}[/tex]

What represents the number written as 23 and 37 thousandths
Answers
The number written as 23 and 37 thousandths can be expressed in decimal form as 23.037.
What is Place value?The foundation of our whole number system is place value. In this approach, the value of a digit in a number is determined by where it appears in the number.
When we write a number like 23.037, each digit to the left of the decimal point represents a different place value. The place values start from the right with ones, then increase by a factor of 10 as we move to the left.
So in the number 23.037:
The digit 7 is in the thousandth place, meaning it represents 7/1000 or 0.007.
The digit 3 is in the hundredth place, meaning it represents 3/100 or 0.03.
The digit 0 is in the tenth place, meaning it represents 0/10 or 0.
The digit 2 is in the one's place, meaning it represents 2 ones, or simply 2.
Therefore, 23.037 can be written as:
23 + 0.037
or
23 and 37 thousandths

Step-by-step explanation:
Given: Two numbers 249 and 271.
To find: Word form of the greater number.
Solution:
We have two numbers 249 and 271.
To find the greater number, we need to compare the two numbers.
To compare the two numbers first of all we will compare the hundreds digit.
The hundreds digit of both the numbers is same that is 2.
Now, we will compare the tens digit of the two numbers.
The tens digit of the number 249 is 4 and the tens digit of the number 271 is 7.
As 7 is greater than 4.
271 is greater than 249.
Now, the word form of 271 is two hundred seventy-one.

A large container holds 8 gallons of water. It begins leaking at a constant rate. After 48 minutes, the container has 5 gallons of water left.
Answers
The rate of leakage of the water from the container is 0.0625 gallons per minute, derived from the initial and final amount of water in the container and the elapsed time.
Explanation:This problem pertains to the concept of rate of change, a fundamental concept in Mathematics. The rate of leakage of the water from the container can be determined by finding the amount of water leaked per minute. Initially, the container holds 8 gallons of water and after 48 minutes, it has 5 gallons of water left. Hence, the water has been leaking from the container at a rate of (8 gallons - 5 gallons) / 48 minutes = 0.0625 gallons per minute. Understanding this concept can help you solve similar problems, for instance, calculating the time it would take to fill a swimming pool with given rate of water flow.

What is the equation of this graphed line?
Answers
y= 6x+7
I think this is it.
y = mx + b
...where b represents the y-intercept and m represents the slope
In this problem, the y-intercept is 7 because you can see that the line intersects the y-axis at the coordinate (0, 7).
The slope is negative because the line is going down when being read from left to right. Two ways you can find the slope of the line is by calculating the rise/run of the line (how many units the line goes up/down by how many units the line goes to the right).
You can also find the slope using the equation :
m = y2 - y1 / x2 - x1
Substitute the coordinates (the order doesn't matter as long as the coordinates correspond).
m = -2 - 7 / 8 - 0
m = -9 / 8
The slope is -9/8.
Combine the information you now know into the line's equation.
Solution: y = - 9/8x + 7
A triangle has an area of 10.5 square feet. The base of the triangle is 6 feet. What is the height?
Answers
Let's put what we know in an equation. We know that B X H / 2 = the area of a triangle.
6 X H (height) / 2 = 10.5 Sq. Ft.
If you want to find the height, let's solve for H. I think we should combine 6 and H together, and that would simplify to 6h / 2 = 10.5.
Now to get 6h by itself, let's multiply by 2 to each side. It would then look like: 6h = 21. To finally get "h" by itself, we need to divide h by 6 to each sides. After you do that, the answer simplified is: h = 3.5.
To make sure my answer is correct, let's plug in the height with the base, if it equals 10.5.
6 X 3.5 / 2 = 10.5
(6 X 3.5 ) / 2 = 10.5
(21) / 2 = 10.5
10.5 = 10.5
My answer is correct, since each side equals the same. Hope this isn't too confusing, hope this helps! =)

Answers
To solve this problem, you need to divide 7/9 by 1/3. The answer is 7/3.
Explanation:To solve this problem, we need to divide 7/9 by 1/3.
Dividing fractions involves multiplying the numerator of the first fraction by the denominator of the second fraction, and the denominator of the first fraction by the numerator of the second fraction.
So, 7/9 ÷ 1/3 = (7/9) x (3/1). Simplifying this gives us 21/9.

When filing separately, both Melvin and Sylvia have a standard deduction of $5700, and each can claim him/herself as an exemption for $3650. Neither has any additional adjustments to income. What is Melvin's taxable income? How about Sylvia's taxable income?
Answers
Melvin and Sylvia's taxable income is calculated by subtracting the sum of the standard deduction ($5,700) and the personal exemption ($3,650) from their adjusted gross income. Since the adjusted gross income was not provided, the exact taxable income cannot be determined without that information.
Explanation:When calculating Melvin and Sylvia's taxable income, we first need to use the given standard deduction and personal exemption to determine their taxable income. According to the information, the standard deduction is $5700 and the personal exemption is $3650 Therefore, we subtract the sum of these deductions from their adjusted gross income to find their taxable income.
Assuming Melvin and Sylvia both have the same adjusted gross income and ignoring any typos or irrelevant parts of the questions being asked, we have:
The formula for each individual's taxable income is as follows:
taxable income = adjusted gross income - (standard deduction + personal exemption)
To find Melvin or Sylvia's taxable income, simply plug their adjusted gross income into the formula.
