A cruise ship can cover 17 nautical miles in 374 minutes. How many nautical miles will it travel in 330 minutes?

Answers

Answer 1

374/17= 22 minutes per nautical mile.
330/22= 15 nautical miles in 10 minutes

To check your work:
17/374=.04545 nautical miles per minute
.04545*330= 14.999 or 15.

So your answer is that the cruise ship covered 15 nautical miles in 330 minutes. I hope that helped!

Answer 2

The ship's speed in deep water is 0.045 nautical miles per minute. In shallow water, the ship's maximum speed typically decreases due to increased drag and turbulence.

To find the speed of the ship in very deep water:

Calculate speed = Distance / Time = 17 nmi / 374 min = 0.045 nautical miles per minute.For the ship's speed in shallow water:It depends on the water resistance; usually, in shallow water, the ship's maximum speed decreases due to increased drag and turbulence.

Draw an imaginary line from the vertex of angle x to the center of the circle.
This divides the 4-sided polygon into two right triangles. For example, the upper right triangle has an acute angle whose measure is 135 degrees / 2, or 67.5 degrees, and the another acute angle whose measure is x/2.

x/2 and 67.5 degrees are complementary angles, so x/2 + 67.5 deg = 90 deg. Thus, x/2 = 22.5 deg, and so x = 45 deg. (answer)

A notebook has a perimeter of 36 inches. It’s area is 80 square inches. What are the dimensions of the notebook

__inches by___ inches

Answers

Let's call he width of the notebook w and the length l

w*l=80

2(w+l)=36
w+l=18
w=18-l

(18-l)*l=80
-l^2+18*l-80=0
l=8 or 10

Therefore, the notebook is 8 by 10 inches

Final answer:

To solve for the dimensions of the notebook, we set up equations based on the perimeter and area, then solved the quadratic equation to find that the dimensions are 10 inches by 8 inches.

Explanation:

To find the dimensions of a notebook with a perimeter of 36 inches and an area of 80 square inches, we will use the formulas for the perimeter and area of a rectangle. The perimeter (P) of a rectangle is 2 times the length (l) plus 2 times the width (w), or P = 2l + 2w. The area (A) of a rectangle is length times width, or A = lw.

Given P = 36 and A = 80, we can set up two equations:

2l + 2w = 36l × w = 80

First, we simplify the perimeter equation to l + w = 18 by dividing everything by 2. We can then express w in terms of l: w = 18 - l. Now, we substitute w into the area equation: l(18-l) = 80. Expanding this gives us a quadratic equation: l2 - 18l + 80 = 0.

To solve the quadratic equation, we look for factors of 80 that add up to 18. The factors are 10 and 8, meaning the length is 10 inches and the width is 8 inches, since l = 10 and w = 8 satisfy both the area and perimeter equations.

Therefore, the dimensions of the notebook are 10 inches by 8 inches.

What is the diameter of a sphere that has a surface area of 1041 square inches?

A) 9.1

B) 22.5

C) 40.3

D) 18.2

Answers

The answer is 18.2
I got the answer by solving it

1st you need equation for the surface area of a sphere which is:
A=4*π*r^2
Where r=radius
r = diameter/2 or d/2

So
area of a sphere = 4*π*(d/2)^2

Plug in the area given
1041 = 4*π*(d/2)^2

Solve for d
1041/(4* π)=82.84

82.84 = (d/2)^2

Sqrt(82.84)=d/2

9.10=d/2

9.10*2= d

18.2=d
So the answer is 18.2 in

The error that Gio is making in finding the surface area of the rectangular pyramid is that He used an expression for surface area that did not include all the faces.

What is Surface Area?

The area of a three dimensional object on it's outer surface is called the surface area of the object.

Given a rectangular pyramid.

Pyramid consists of one rectangular side and 4 triangular faces of which each pair of triangular faces is identical.

Total surface area of the pyramid is the total surface area of each faces.

Area of rectangular face = (4.2) (9.6)

Area of the triangular faces = [2 × 1/2 × 4.2 × 6.5] + [2 × 1/2 × 9.6 × 4.8]

= (4.2) (6.5) + (9.6) (4.8)

Total area = (4.2) (9.6) + (4.2) (6.5) + (9.6) (4.8)

So his mistake is that he only find the areas of two triangular faces.

Hence the correct option is that He used an expression for surface area that did not include all the faces.

What is the equation of a circle with center (8, 4) and radius 7?

Answers

Final answer:

The standard form of the equation of a circle is given by (x-h)² + (y-k)² = r², where (h, k) are the center and r is the radius. For a circle with center at (8, 4) and radius 7, the equation of the circle becomes (x - 8)² + (y - 4)² = 49.

Explanation:

The equation of a circle in standard form is given by (x-h)² + (y-k)² = r², where (h, k) are the coordinates of the center of the circle and r is the radius. This formula comes from Pythagorean theorem and how a circle is defined as the locus of points equidistant from a given point (the center).

By substituting the given center and radius into this formula, we can write the equation of the specific circle you're asking about. The center of this circle is (h, k) = (8, 4), and its radius is r = 7. Therefore, the equation of the circle is (x - 8)² + (y - 4)² = 7² or (x - 8)² + (y - 4)² = 49.

Use the mid-point rule with n = 4 to approximate the area of the region bounded by y = x3 and y = x. (10 points)

Answers

See the graph attached.

The midpoint rule states that you can calculate the area under a curve by using the formula:
[tex]M_{n} = \frac{b - a}{2} [ f(\frac{x_{0} + x_{1} }{2}) + f(\frac{x_{1} + x_{2} }{2}) + ... + f(\frac{x_{n-1} + x_{n} }{2})][/tex]

In your case:
a = 0
b = 1
n = 4
x₀ = 0
x₁ = 1/4
x₂ = 1/2
x₃ = 3/4
x₄ = 1

Therefore, you'll have:
[tex]M_{4} = \frac{1 - 0}{4} [ f(\frac{0 + \frac{1}{4} }{2}) + f(\frac{ \frac{1}{4} + \frac{1}{2} }{2}) + f(\frac{\frac{1}{2} + \frac{3}{4} }{2}) + f(\frac{\frac{3}{4} + 1} {2})][/tex]
[tex]M_{4} = \frac{1}{4} [ f(\frac{1}{8}) + f(\frac{3}{8}) + f(\frac{5}{8}) + f(\frac{7}{8})][/tex]

Now, to evaluate your f(x), you need to look at the graph and notice that:
f(x) = x - x³

Therefore:
[tex]M_{4} = \frac{1}{4} [(\frac{1}{8} - (\frac{1}{8})^{3}) + (\frac{3}{8} - (\frac{3}{8})^{3}) + (\frac{5}{8} - (\frac{5}{8})^{3}) + (\frac{7}{8} - (\frac{7}{8})^{3})][/tex]

[tex]M_{4} = \frac{1}{4} [(\frac{1}{8} - \frac{1}{512}) + (\frac{3}{8} - \frac{27}{512}) + (\frac{5}{8} - \frac{125}{512}) + (\frac{7}{8} - \frac{343}{512})][/tex]

M₄ = 1/4 · (2 - 478/512)
= 0.2666

Hence, the area of the region bounded by y = x³ and y = x is approximately 0.267 square units.

Using the mid-point rule with n = 4, we approximate the area bounded by y = x³ and y = x b as 0.2578125.

To approximate the area of the region bounded by y = x³ and y = x using the mid-point rule with n = 4, we follow these steps:

Determine the points of intersection between y = x³ and y = x. Solving x³ = x, we get the points of intersection at x = 0 and x = 1.

Divide the interval [0, 1] into 4 subintervals, each of width Δx = (1 - 0)/4 = 0.25.

Calculate the midpoint of each subinterval: 0.125, 0.375, 0.625, and 0.875.

Evaluate the functions y = x³ and y = x at these midpoints:

At x = 0.125: y = x³ = 0.125³ = 0.001953125 and y = x = 0.125At x = 0.375: y = x³ = 0.375³ = 0.052734375 and y = x = 0.375At x = 0.625: y = x³ = 0.625³ = 0.244140625 and y = x = 0.625At x = 0.875: y = x³ = 0.875³ = 0.669921875 and y = x = 0.875

Determine the heights of the rectangles by finding the difference between the values of y:

At x = 0.125: Δy = 0.125 - 0.001953125 = 0.123046875At x = 0.375: Δy = 0.375 - 0.052734375 = 0.322265625At x = 0.625: Δy = 0.625 - 0.244140625 = 0.380859375At x = 0.875: Δy = 0.875 - 0.669921875 = 0.205078125

Compute the area of each rectangle (height × width) and then sum them up:

Area at x = 0.125: 0.123046875 × 0.25 = 0.03076171875Area at x = 0.375: 0.322265625 × 0.25 = 0.08056640625Area at x = 0.625: 0.380859375 × 0.25 = 0.09521484375Area at x = 0.875: 0.205078125 × 0.25 = 0.05126953125

Add the areas to get the total approximate area:

0.03076171875 + 0.08056640625 + 0.09521484375 + 0.05126953125 ≈ 0.2578125

Therefore, the approximate area of the region bounded by y = x³ and y = x using the mid-point rule with n = 4 is 0.2578125.

The radius of Earth at a latitude of 17 is about 3790 miles. Suppose that you could fly from Acapulco directly west to Hyderabad or fly directly north to Hyderabad. Which way would be shorter, and by how much? Use 3960 miles for Earths radius. (Hint: To fly directly north, you would go from 17 north latitude to 90 north latitude, and then back down to 17 north latitude.) I add 20 to my number and subtract 17 from the new number. the answer is 37. what is my number? Assume that the population of the world in 2010 was 6.9 billions and is growing at the rate of 1.1 percent a year. (a) set up a recurrence relation for the population of the world n years after 2010 (b) find an explicit formula for the population of the world n years after 2010. (c) what will the population of the world be in 2030 Meiosis produces..?A.) gametesB.) somatic cellsC.) body cellsD.) mitotic cells Ariel has a standard deck of 52 cards.

The students are presenting projects to th When the brain receives the message that the environment around the body is very cold, the temperature signal begins in neurons of the For groups of students are doing a probability experiment with a standard number cube to see how many times they roll of four. The theoretical probability of rolling in for is one out of six or approximately 0.17 and one group came close to this possibility with an experimental probability of 0.175. This most likely came from which group When evaluating ms. hanks' creditworthiness, can herman take into account that ms. hanks lives in bastrop valley, and generally people there are a credit risk?
