Answer:

The nautical mile is based on the Earth's longitude and latitude coordinates, with one nautical mile equaling one minute of latitude.

Step-by-step explanation:

If the length of a side of each square is 1 nautical mile, the shortest distance between the two paths will be √2 nautical miles.

It is defined as a two-dimensional geometry that has four sides and four vertices. The sides of the square are equal in length. Square is a regular quadrilateral.

It is given that two ships follow parallel paths and the length of a side of each square is 1 nautical mile,

When two nodes in a graph are connected, the path with the fewest edges is known as the shortest path. It is a path with the least sum of edge weights if the graph is weighted. The length of the shortest path is referred to as the "shortest distance".

Thus, if the length of a side of each square is 1 nautical mile, the shortest distance between the two paths will be √2 nautical miles.

The figure goes towards left and down.

Option B is the correct answer.

Given function is (x, y) → (x a, y b).

Also given that the value of a is negative and the value of b is negative.

Let us consider a graph whose horizontal axis represents the values of x and the verticle axis represents the values of y. The graph will have four quadrants starting from the top-right end.

If the values of a and b are negative, then it will fall under quadrat 3.

Hence we can conclude that the figure will moves left and down.

Okay, so I'm gonna start by multiplying both sides Fire lt to get rid of our, um, faction. So we have six year and 70 here we get three X minus two is much is greater than or equal to negative one. Okay. Or, um, 20 acts is less iniquity. Seven. Okay, so it's to to both sides here. So we get three x is gooder than or equal to one, and then X must be greater than or equal to 1/3. And then for here we have X must be less than or equal to 7/20. Okay, so let's go to Paula. So which one is greater than the other one? Over three is 1.33 and then 7/20 is point to be five. So we see that 7/20 is larger than from one over tree. Okay, so we want X to be greater than or equal to one over. So we're including 1/3, and we want to be greater than so we're going off to infinity. And then we have exes, Dustin, or equal to seven or 20 who were including 7/20 and we want to be glass, then seven or 20. So we're going off to negative infinity. And since we have are connected or we want the union of all for peace, that's from negative infinity to infinity.

Theresa uses 14.81 inches of fabrics on an headband and 8.54 inches on a wristband for each player.  

She uses 533.16 inches of fabric on  headbands for 33 players and 3 coaches.

let

x = fabric use for each headbands

Therefore,

33x + 3x = 533.16

36x = 533.16

x = 533.16 / 36

x = 14.81 inches

let

y = fabrics use for each wristband for players

33y = 281.82

y = 281.82 / 33

Answer:

It is a right triangle.

So, using Pythagorean theorem: OS² = OR² - RS²

OR = r (radius) + 8

OS = r

RS = 16

=> r² = (r+8)² - 16²

r² = r² + 16r + 64 - 256

r² = r² + 16r - 192

16r = 192

r = 192 / 16 = 12cm²

a) 12 cm²

b) 12 + 8 = 20 cm²

Answer:

50 dimes 90 quarters

Step-by-step explanation:

this problem needs 2 equations

1. D+Q = 140 ( shows the total amount of coins )

2. 0.1D+0.25Q = 27.50 ( shows the total cost )

the best way to do this is by subtraction

to get D by itself, the first equation would turn into D = 140 - Q

plug 140-Q into the second equation where you see D and solve for Q

once you solve it you should get Q = 90 then to get D it would be 140 - 90 which gives you D = 50.

Step-by-step explanation:

Let the number of cell phones be represented by X;

Price per cell phone = $20

$150 is a constant

Minimum goal per week = $630

The inequality will be;

150 + 20X  630

20X  630 -150

20X  480

Divide both sides by 20 to solve for X;

X 480/20

X  24

Therefore, you must sell at least 24 cell phones.

The equation solved for x is x = √(2U)/k, hence, option (D) is correct.

Two or more expressions with an equal sign are defined as an equation.

Given that, U = (1/2)kx².

Solve the equation for x:

U = (1/2)kx²

2U = kx²

(2U)/k = x²

Or, x² = (2U)/k

x = √(2U)/k

The equation solved for x is x = √(2U)/k, hence, option (D) is correct.
