A scuba diver is 15.5 feet below the surface of the water. If the diver continues to swim downward at a rate of 2.5 feet per second, what is her location, in feet, relative to the surface after 712 seconds? feet
The answers is: 33
33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.
Step-by-step explanation:
Given:
A scuba diver is 15.5 feet below the surface of the water.
The diver continues to swim downward at a rate of 2.5 feet per second.
Now, to find the integer represents her location relative to the surface after 7 seconds.
And to find how far does the diver have to go to return to the surface.
So, to get the integer represents her location relative to the surface after 7 seconds.
Initial depth = 15.5 feet.
Distance traveled down = 7 × 2.5 = 17.5 feet.
Final depth of water surface = Initial depth + Distance traveled down.
Final depth of water surface = 15.5 feet + 17.5 feet.
Final depth of water surface = 33 feet.
Thus, 33 is the integer represents her location relative to the surface after 7 seconds.
Now, to get how far does the diver have to go to return to the surface:
As, the diver goes to 33 feet down to the surface.
Thus, the diver to return she have to go through the same distance.
So, to return to the surface she need to go to 33 feet far.
Therefore, 33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.
For each function below, find its domain and then determine if the function increasing, decreasing, or constant on each piece of the domain. Sometimes the domain is just one interval, but the function still changes its behavior at some points. s(t)=\(\frac{-5}{|t|}\)
The interval on which the function is decreasing is : ( , )
The interval on which the function is increasing is : ( , )
The interval on which the function is constant is : ( , )
Leave unused fields blank.
Answer and explanation:
First, the domain is all real numbers except 0, since x = 0 is the asymptote.
D: x ∊ R, x ≠ 0
or
D: (-∞, 0) ∪ (0, ∞)
The range is everything below y = 0.
R: y < 0
or
R: (0, -∞)
Next, this function is never constant so there are only intervals of increasing and decreasing. The intervals meet at x = 0.
inc: x > 0
dec: x < 9
or
inc: (0, ∞)
dec: (0, -∞)

1/3; 2/3
1/2; 1/2
5/6; 1/2
1/6; 5/6
Brainlist for positive attitude and correct answer :D
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Answer:
a. yes, the cost is proportional to the time
b. $180,000 per second
Step-by-step explanation:
You want to know if the given table of costs and commercial lengths indicates the cost is proportional to the time.
ProportionThe cost is proportional to the time if it can be described by the equation ...
cost = k × time
where k is a constant called the constant of proportionality.
We can find k by dividing cost by time:
cost/time = k
Constant of proportionalityTo see if k is a constant, we need to use consistent units when comparing cost divided by time. Since part B asks for dollars per second, we choose to use those units for finding k.
15 second commercial: k = ($2,700,000)/(15 s) = $180,000 per second
60 second commercial: k = ($10,800,000)/(60 s) = $180,000 per second
As the attachment shows, the costs for the longer commercials are the same in terms of dollars per second.
a) Proportional to timeThe "dollars per second" values for all of the commercials are the same, so we can conclude the cost is proportional to the length of time.
b) Cost per secondAs we found in part (a), the cost is $180,000 per second.
__
Additional comment
When you are asked for "dollars per second," you find that value by dividing dollars by seconds, as we did above. Effectively, "per" means "divided by" in this context.

ChoiceD: a circle graph titled social media usage, with four sections labeled picturegram 17 percent, tweeter 48 percent, vidtok 25 percent, and headbook 10 percent
Answer:
The answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Step-by-step explanation:
By adding all the numbers you get 500, but you need to make it 100% so you divide the total number by five. To know what percent out of 100 you need to divide all of the variables by 5.
85 ÷ 5 = 172
40 ÷ 5 = 48
125 ÷ 5 = 25
50 ÷ 5 = 10
Thus the answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

In 56 years, Kevin will be 9 times as old as he is now
How old is Kevin now?
Answer:
correct answer is 7 years
Step-by-step explanation:
A+56=9(A)
56+9A
A=7
he will be 7 years old he is pretty old
Answer:
Kevin is 7 years old right now.
Step-by-step explanation:
Let x be Kevin's age right now, that's what we're trying to find.
In 56 years, he'll be 9 times older than he is now, so we can say:
x + 56 = 9x
Now we can get the x values on the right side of the equation so that:
56 = 8x
Now solve for x and you have his current age which is 7.
A pitcher contains 14.25 cups of iced tea. You drink 2.5 cups of the tea each morning and 2.25 cups of the tea each evening. When will you run out of iced tea?
Answer:
You will run out of iced tea in 3 days (a total of 3 mornings and 3 evenings)
Step-by-step explanation:
Day 1 - 9.5 cups left
14.25 - 2.5 - 2.25 = 9.5
Day 2 - 4.75 cups left
9.5 - 2.5 - 2.25 = 4.75
Day 3 - 0 cup left
4.75 - 2.5 - 2.25 = 0
Answer: You will run out of iced tea in 3 days
Step-by-step explanation:
2.5 + 2.25 = 4.75
14.25/4.75 = 3

Answer:
\(\frac{16}{27}\)
Step-by-step explanation:
From the table, we notice that the total number of students is:
\(3+10+8+6=27\)
Then, along the second column of the table, we notice that the number of students who do not have a brother is:
\(10+6=16\)
So, the probability that a randomly chosen student does not have a brother is:
\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)
Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

Evaulate each expression when n = 2.3
N + 8n2 - 17=
Answer: 27.62
Step-by-step explanation:
plug in 2.3 wherever 'n' is
I'm assuming that the '2' in 8n2 is an exponent
2.3 + 8(2.3)² - 17 =
Using PEMDAS
start out with exponent since there isn't any parenthesis
(2.3)² = 5.29
2.3 + 8(5.29) - 17
move on to multiplication
8(5.29) = 42.32
2.3 + 42.32 - 17
with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there
2.3 + 42.32 = 44.62
then the subtraction
44.62 - 17 = 27.62
Answer:
Step-by-step explanation:
The answer is 27.62
