A scuba diver is 30 feet below the surface of the water 10 seconds after he entered the water and 100 feet below the surface after 40 seconds. What is the scuba diver's rate of change? Round to the nearest tenth.
Answer:
2.3 feet/ second
Step-by-step explanation:
To find the rate of change, we will have to find the difference in his distance travelled and divide it by the time taken to move that distance.
This is given by rate of change = (change in position)/ change in time
From the question, his position changed from 30 ft to 100 ft thus the distance he travelled is = 100ft - 30 ft = 70 ft.
Time taken to travel this distance = 40 seconds - 10 seconds = 30 seconds
Diver's rate of travel = 70 ft / 30 seconds = 2.33333ft/second.
Rounding off the answer to the nearest tenth, we have 2.3 ft/second

An audiometer produces a pure tone with a frequency f of 1200 hertz (cycles per second). The maximum pressure P produced from the pure tone is 5 millipascals. Write a sine model that gives the pressure P as a function of the time t (in seconds). Assume P=0 when t=0.
The pressure P as a function of time t can be modeled using the sine function. The maximum pressure is 5 millipascals. The wavelength, frequency, and speed of the sound wave can be calculated using formulas.
Explanation:The sine model that gives the pressure P as a function of time t is:
P(t) = 5 millipascals * sin(2π * 1200 * t)
Maximum change in pressure: The maximum change in pressure is 5 millipascals.
Wavelength: The wavelength of the sound wave can be calculated using the formula: wavelength = speed / frequency. Since the speed of sound in air is approximately 343 meters per second, the wavelength is approximately 0.285 meters.
Frequency: The frequency of the sound wave is 1200 hertz (cycles per second).
Speed of the sound wave: The speed of the sound wave can be calculated using the formula: speed = wavelength * frequency. Using the values we have, the speed of the sound wave is approximately 343 meters per second.
Final answer:
The sine model that gives the pressure P as a function of time t for an audiometer producing a pure tone at 1200 Hz with a maximum pressure of 5 millipascals is P(t) = 5 · sin(2π · 1200t).
Explanation:
To write a sine model that gives the pressure P as a function of the time t for a sound wave produced by an audiometer, we can use the standard form of a sine function for a periodic wave:
P(t) = Pmax · sin(2πft + φ)
Since we are given that Pmax is 5 millipascals, the frequency f is 1200 hertz, and P=0 when t=0 (which implies that the initial phase shift φ is zero), we can plug these values into the sine model to get:
P(t) = 5 · sin(2π · 1200t)
Here, we converted the maximum pressure from millipascals to pascals, and since the sine of 0 is 0, we have a phase shift of 0 radians, simplifying the equation.

Answer:
3.2
Step-by-step explanation:
First, you have to arrange them in proper numerical order (least to greatest).
84, 88,90,92,96
Next, find the mean by adding them all up and dividing them by 5.
84 + 88 + 90 + 92 + 96 = 450
450 divide by 5 equals 90.
Now, that we have our mean, we have to subtract it from each of the numbers in the data set. Remember this is absolute so there is no negatives.
84 - 90 = 6
88 - 90 = 2
90 - 90 = 0
92 - 90 =2
96 - 90 = 6
Next, line them up again.
2,2,6,6
Find the mean of them:
2 + 2 + 6 + 6 = 16
16 divided by 4 is 4.
Therefore, our answer would be the MAD is 4.0

The graph shows the market for graphic t-shirts. What does the graph show about the relationship between a product and its price
The graph shows an inverse relationship between the price of graphic t-shirts and the quantity demanded. As the price decreases, the quantity demanded increases, and vice versa. The demand for graphic t-shirts is elastic, meaning changes in price have a significant impact on the quantity demanded.
Explanation:The graph shows the relationship between the price of graphic t-shirts and the quantity demanded. In general, as the price of the t-shirts decreases, the quantity demanded increases, and vice versa. This is known as the law of demand, which states that there is an inverse relationship between price and quantity demanded.
For example, if the price of a graphic t-shirt is $20, the quantity demanded might be 100. But if the price decreases to $15, the quantity demanded might increase to 150.
By analyzing the demand curve shown in the graph, we can see that the demand for graphic t-shirts is elastic. This means that changes in price have a significant impact on the quantity demanded.

His gross monthly income is $608.00, and his take-home pay is $501.64. In his spare time, Caleb walks a dog belonging to an elderly neighbor. He earns an additional $40 per month for that chore. What is Caleb's net monthly income? Remember net income is your take home pay.
Answer:
$541.64
Step-by-step explanation:
Caleb's take Home Pay from the Restaurant =$501.64
He earns an additional $40 per month for dog-walking.
Therefore,
Caleb's net monthly income =$501.64+40 =$541.64
Final answer:
Caleb's net monthly income is $541.64 after factoring in his take-home pay and additional earnings.
Explanation:
Caleb's net monthly income is calculated by subtracting his take-home pay from his additional earnings from walking the dog:
Caleb's take-home pay = $501.64
Additional earnings from walking the dog = $40
Net income = Take-home pay + additional earnings = $501.64 + $40 = $541.64
What does it mean
by round to the nearest degree.
Answer:
Rounding up to the nearest degree is equivalent to rounding up to the nearest whole number (or integer)
Step-by-step explanation:
Any value between degrees above .5 is rounded up to the next degree, so for instance:
30.4 --> 30
30.5 --> 31
30.999 --> 31
31 --> 31
31.499 --> 31
Rounding values expressed in degrees and minutes is similar to rounding decimals.
What is mean by rounding off?Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.

When Rahul began 7th grade, he put his savings of $3,000 in an account that compounded interest annually. He hoped to have $6,000 by the time he graduates high school in six years. What interest rate is required for him to reach his goal?
An interest rate of ______%
is required.
Final answer:
To double Rahul's savings of $3,000 to $6,000 in six years through compound interest, the required annual interest rate is approximately 12.25%.
Explanation:
The student wants to determine the interest rate needed for his savings to grow from $3,000 to $6,000 over a period of six years with compound interest compounded annually. We can use the formula for compound interest: A = P(1 + r)^n, where A is the amount of money accumulated after n years, including interest, P is the principal amount (initial sum of money), r is the annual interest rate, and n is the number of years the money is invested for.
To solve this, use the formula with A = $6,000, P = $3,000, and n = 6 years, and then solve for r:
6,000 = 3,000(1 + r)⁶
Dividing both sides by 3,000:
2 = (1 + r)⁶
Now we must take the sixth root of both sides to solve for (1 + r):
(1 + r) = √⁶(2)
Then subtract 1 from both sides to solve for r:
r = √⁶(2) - 1
Using a calculator, simply compute the sixth root of 2, subtract 1, and convert to percentage to find the required interest rate:
r = 0.122462… or 12.2462%
Therefore, the interest rate required is approximately 12.25%.

Solve for x. *
(5x + 13)
(9x - 31)
Answer:
x=11
Step-by-step explanation:
5x+13=9x-31
subtract 9 from both sides.
-4x+13=-31
you want to isolate the x value so subtract 13 from both sides.
-4x=-44
now divide both sides by -4.
x=11
The solution for the variable x for given the equation (5x + 13) = (9x - 31) is equal to x = 11.
For the equation (5x + 13) = (9x - 31)
Expand the equation: 5x + 13 = 9x - 31
Combine like terms: 13 = 4x - 31
Isolate x: 4x = 44, x = 11
Therefore, the value of the variable x in the given equation is x = 11.
The above question is incomplete, the complete question is:
Solve for x.

A bag of marbles contains 4 green marbles ,3 blue marbles,2 red marbles,and 5 yellow marbles.how many outcomes Are there when choosing a marble from the bag?
The total number of possible outcomes when choosing one marble from the bag is 14, accounting for all the different colored marbles present in the bag.
Explanation:The question is about calculating the total number of possible outcomes when choosing a marble from a bag with a mixed assortment of marbles. The bag contains 4 green marbles, 3 blue marbles, 2 red marbles, and 5 yellow marbles. To find the number of possible outcomes, you simply add the number of each color of marble in the bag.
So the total number of outcomes when choosing one marble from the bag is:
4 (green) + 3 (blue) + 2 (red) + 5 (yellow) = 14 outcomesTherefore, there are 14 different outcomes when selecting a single marble from the bag.
Final answer:
To find the number of outcomes when choosing a marble from a bag, add the number of each color marble to get the total count. Each marble represents one outcome, so with 4 green, 3 blue, 2 red, and 5 yellow marbles, there are 14 possible outcomes in total.
Explanation:
The student is asking about the number of possible outcomes when choosing a marble from a bag containing specific numbers of differently colored marbles. The total number of marbles in the bag is the sum of the individual marbles of each color. Here's how you calculate the number of outcomes:
Count the total number of marbles: 4 green marbles, 3 blue marbles, 2 red marbles, and 5 yellow marbles.Add up the number of each type of marble to get the total number of marbles in the bag. So, you would have 4 + 3 + 2 + 5 = 14 marbles in total.Since you are choosing one marble from the bag, each marble is a potential outcome. Therefore, there are 14 possible outcomes when choosing a single marble from the bag.In problems involving probability, such as those provided for reference, it's important to consider whether the events are independent or not, and whether you're replacing the marble after drawing it. These details will affect the calculation of probabilities and the number of possible outcomes.

A cylindrical oil from has a diameter of 2ft and a height of 3 feet. What is the volume of the oil drum?
Answer:
The volume of the cylinder is 9.42ft³
Step-by-step explanation:
radius = half of diameter
r = 2ft /2 = 1ft
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 3ft
π = 3.14
r = radius = 1ft
v = (π * r²) * h
we replace with the known values
v = (3.14 * (1ft)²) * 3ft
v = (3.14 * 1ft²) * 3ft
v = 3.14ft² * 3ft
v = 9.42ft³
The volume of the cylinder is 9.42ft³

Answer:
a.15x+6y= 900
b. The graph is attached.
c. 25
Step-by-step explanation:
a. From the information provided, the linear equation has to express that the number of tickets multiply for its price plus the number of snacks multiply for its price would be equal to $900:
15x+6y= 900
x= number of tickets
y= number of snacks
b.
When x= 0:
15(0)+6y= 900
y=900/6= 150
When y=0
15x+6(0)= 900
x=900/15= 60
With these points, you can graph the linear equation and the image is attached.
c. You have to replace the value of x in the equation and isolate y:
15x+6y= 900
15(50)+6y= 900
750+6y=900
6y= 900-750
6y= 150
y= 150/6
y= 25

A section of a deck is shaped like a trapezoid. For this section, the length of one base is 53 feet, and the length of the other base is 46 feet. The height is 16 feet. What is the area of this section of the deck?
Answer:
792 ft²
Step-by-step explanation:
The formula for area of a trapezoid is A = [tex]\frac{a+b}{2}[/tex] * h, where a = length of base (a) and b = length of base (b) and h = height of trapezoid.
If we plug the shown values, the formula becomes
[tex]\frac{53 + 46}{2}[/tex] * 16
This simplifies to 49.5 * 16, which equals 792. The answer with units is 792 ft².
