Shanika ends up paying more for her utilities, and she paid $35.875 more than Vanesa.

1. Standard Use Plan

2. Interval Use Plan

3. Both women use 1,325 kWh for the given 30 day period

As given to us Shanika is using the Standard use plan, and her usage is  1,325 kWh. so,

        [tex]400\times 7.5\\=3,000\ \rm cent[/tex]

        [tex]400\times 10\\=4,000\ \rm cent[/tex]

        [tex](1325-800)\times 12.5\\= 525 \times 12.5\\= 6,562.5\ cent[/tex]

The total bill of Shanika

[tex]3,000\cent + 4,000\ cent +6,562.5\ cent\\= 13,562.5\ cent\\= \$135.625[/tex]

Thus, the total bill of Shanika is $135.625.

As given to us Vanesa is using the Interval use plan. Also, Vanesa uses 500 kWh during on-peak hours and 825 during off-peak hours.

       = Amount of electricity used x Rate of electricity

       = 500 kWh x 15 cents/kWh

       = 7,500 cent

       = Amount of electricity used x Rate of electricity

       = 825 kWh x 3 cents/kWh

       = 2,475 cent

The total bill of Vanesa

= 7,500 cent + 2,475 cent

= 9,975 cent

= $99.75

Thus, the total amount paid by Vanesa is $99.75.

Therefore, the amount paid by Shanika is more.

The difference between the bill amount of both the womens

= total bill of Shanika - total bill of Vanesa

= $135.625 - $99.75

= $35.875

Hence, Shanika ends up paying more for her utilities, and she paid $35.875 more than Vanesa.

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

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.

Pythagorean Theorem

c^2 = a^2 + b^2

a = 20

b = 15

c = ?

c^2 = 20^2 + 15^2

c^2 = 400 + 225

c^2 = 625                    Take the square root of both sides.

√c^2 = √625

c = 25

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.

Regular decagon is a closed shaped polygon witch has ten sides.In a regular decagon all ten sides are equal. The area of the given regular decagon is near 663.1 squared units. Thus the option 3 is the correct option.

The radius of a regular decagon is 15 units.

The length of one side of the polygon measures about 9.3 units.

Regular decagon is a closed shaped polygon witch has ten sides.In a regular decagon all ten sides are equal.

The area of the regular decagon with side [tex]a[/tex] can be given as,

[tex]A=\dfrac{5}{2} a^2\sqrt{5+2\sqrt{5} }[/tex]

Thus the area of the regular decagon having the the side length equal to the 9.3 units is,

[tex]A=\dfrac{5}{2} \times(9.3)^2\times\sqrt{5+2\sqrt{5} }\\A=665.47[/tex]

Thus the area of the regular decagon having the the side length equal to the 9.3 units is 665.47 squared units..

The area of the regular decagon is in decimal form. When 665.47 is rounded to the nearest tenth the value is 670 squared units.

Hence the area of the given regular decagon is near 663.1 squared units. Thus the option 3 is the correct option.

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.

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.
