. An oil spill, with the appearance of black to dark brown, is sighted by a commercial airliner flying over the Great Barrier Reef. The spill is estimated to be 1.5 kilometers long and 50 meters wide. How much oil (in liters) would there be in the spill
If we assume an average height of 1 meter, the estimated amount of oil in the spill would be approximately 75,000,000 liters.
To determine the amount of oil in the spill, we need to calculate the volume of the spilled oil.
Given:
Length of the spill = 1.5 kilometers = 1500 meters
Width of the spill = 50 meters
To find the volume, we multiply the length, width, and average height of the spill. However, since the height of the oil spill is not provided, we cannot provide an exact value. The volume will depend on the thickness of the oil layer.
If we assume a hypothetical average height of 1 meter (which is just an example and may not represent the actual spill), we can calculate the volume as follows:
Volume = Length × Width × Height
= 1500 meters × 50 meters × 1 meter
= 75,000 cubic meters
Now, to convert the volume from cubic meters to liters, we need to multiply by 1000 (since 1 cubic meter is equal to 1000 liters):
Volume in liters = 75,000 cubic meters × 1000
= 75,000,000 liters
Therefore, if we assume an average height of 1 meter, the estimated amount of oil in the spill would be approximately 75,000,000 liters.

Barba bought 5 amusement park tickets at a cost of $30. If she bought 7 tickets how much would it cost
In this given scenario, if Barba were to buy 7 tickets, she would need to pay $42 in total.
Barba purchased 5 amusement park tickets for a total cost of $30.
To determine the cost of 7 tickets, we first need to find the cost of one ticket, which we assume to be x.
By dividing the total cost of $30 by the number of tickets (5), we find that each ticket is priced at $6.
Substituting this value into the equation, we can calculate the cost of 7 tickets by multiplying the cost of one ticket ($6) by the number of tickets (7), resulting in a total cost of $42.
Therefore, if Barba were to buy 7 tickets, she would need to pay $42 in total.

The Greenland ice sheet contains about 3 million cubic kilometers of ice. If completely melted, this ice would release about million cubic kilometers of water, which would spread out over Earth's approximate million square kilometers of ocean surface. How much would the sea level rise?
Complete question :
The Greenland ice sheet contains about 3 million cubic kilometers of ice. If completely melted, this ice would release about 2.2 million cubic kilometers of water, which would spread out over Earth's approximate 343 million square kilometers of ocean surface. How much would the sea level rise?
Answer:
6.4139941 m
Step-by-step explanation:
Given that:
Volume of water that will be released if ice sheet was melted = 2.2million km³
Area of ocean surface = 343 million km²
Rise in sea level :
Volume of water realeased / Area of ocean surface
2.2 * 10^6 / 343 * 10^6
0.0064139 * 10^(6-6)
0.0064139 * 10^0
0.0064139 * 1
= 0.0064139 km
(0.0064139 * 1000)m = 6.4139941 m
Randy is designing a circular garden that is 18 feet in diameter. He is buying plastic edging that costs $1. 50 per foot. He can only buy edging in whole-foot amounts. How much does it cost Randy to buy edging for his garden? Use 3. 14 for pie.
If the diameter of circular-garden is 18 feet, then it will cost Randy an amount of $85.50 to buy edges for his garden.
The "Circumference" of circle is defined as the "total-length" of the boundary or the outer edge of the circle.
The circumference formula is : Circumference = π × Diameter,
The "diameter" of garden is = 18-feet,
So, Circumference = 3.14 × 18 = 56.52 feet,
Since, Randy needs to buy plastic-edging to cover the entire circumference of garden, he needs to buy 56.52 feet of edging.
We know that, Randy can only buy edging in whole-foot amounts,
So, rounding up to the nearest whole foot, we get 57 feet,
The cost of edging is = $1.50 per foot,
So, "total-cost" for Randy to buy edging for his garden is,
⇒ Total Cost = (Cost per foot) × (Number of feet),
⇒ $1.50 × 57,
⇒ $85.50
Therefore, it will cost Randy $85.50 to buy edging for his circular garden.

F is the velocity field of a fluid flowing through a region in space. Find the flow along the given curve in the direction of increasing t. F = (z - x) i + x k r(t)=(sin t) i + (cos t)k, 0 <= t <= pi The flow is. (Type an exact answer in terms of pi.)
The flow along the given curve, in the direction of increasing t, is pi.
The flow along the curve in the direction of increasing t, we need to evaluate the line integral of the velocity field F along the given curve.
The given velocity field is F = (z - x) i + x k, and the curve r(t) = (sin t) i + (cos t) k, where t ranges from 0 to pi.
The line integral is given by the formula: ∫ F · dr = ∫ (F · r'(t)) dt.
Let's calculate the dot product F · r'(t):
F · r'(t) = [(z - x) i + x k] · [(cos t) i - (sin t) k]
= (z - x)(cos t) + x(-sin t)
= z cos t - x cos t - x sin t.
Integrating the dot product with respect to t from 0 to pi, we get:
∫ (z cos t - x cos t - x sin t) dt = [z sin t - x sin t + x cos t] evaluated from 0 to pi.
Substituting the values of t = pi and t = 0 into the expression, we have:
[z sin pi - x sin pi + x cos pi] - [z sin 0 - x sin 0 + x cos 0]
= (0 - 0 + x(-1)) - (0 - 0 + x(1))
= -2x + 2x
= 0.
Therefore, the flow along the given curve, in the direction of increasing t, is 0, as the line integral evaluates to 0.

A random sample of a specific brand of snack bar is tested for calorie count, with the following results: tableau3 ((149 142 152 140 140)(138 150 140 142 ) ) Assume the population standard deviation is of 20 and that the population is approximately normal. Construct a 95% confidence interval for the calorie count of the snack bars. Select one: OA (138.8, 148.6) OB. (104.5, 182.9) OC. (140.3, 147.1) OD. (130.6, 156.7)
The 95% confidence interval for the calorie count of the snack bars is (138.8, 148.6). This means that we are 95% confident that the true population mean calorie count for the snack bars lies within this interval.
The sample mean calorie count is 145.4. The standard error of the mean is 20 / sqrt(10) = 4.47. The z-score for a 95% confidence interval is 1.96. Therefore, the confidence interval is calculated as follows:
(mean + z-score * standard error) = (145.4 + 1.96 * 4.47) = (138.8, 148.6)
This confidence interval tells us that we are 95% confident that the true population mean calorie count for the snack bars lies between 138.8 and 148.6.

If units of a certain commodity are produced, then the marginal cost is dc/da = 9x^2+4x+15x ^1/4 + 10. Suppose the total cost of producing the 1st unit is 100. Calculate the total cost of producing the first 16 units. (calculus 1)
If a certain unit of a commodity is produced with a marginal cost of \(\frac{dc}{da} =9x^{2}+4x+15x^{1/4} +10\), the cost of producing the first 126 units is 289.4
How to differentiate a function?
Differentiation is a way of showing rate of change of a function at a given time.
The given function \(\frac{dc}{da} =9x^{2}+4x+15x^{1/4} +10\),
Differentiate with respect to x
\(\frac{dc}{da} =18x+4+\frac{15}{4} x-^{3/4}\)
input the value 100 for the value of x,
This implies that \(\frac{dc}{da} =18x+4+\frac{15}{4} x-^{3/4}\)
\(\frac{dc}{da}\)=1800+4+\(\frac{15}{4}\) x\(\frac{1}{\sqrt[4]{100^{3} } }\)
\(\frac{dc}{da}=1800+4+\frac{15}{4}x\frac{1}{3.16}\)
Simplifying further
\(\frac{da}{da} =1804+4.75\)
\(\frac{dc}{da} =1808.75\\\)
To produce the first 16 units,
\(\frac{1808.75}{100} }\) x \(\frac{16}{1}\)
The cost of producing the first 16 units is 289.4
