The amount of money she spends per year on utility bills for the air conditioner is; D: $176.40

We are told that;

Cost of running the air conditioner = 7 hours per day

Cost of running the air conditioner = 21 cents per hour = $0.21 per hr.

She runs it for four months at 7 hours per day. Thus;

Total number of hours for the 4 months = 7 × 30 × 4 = 840 hours

Total cost for the 4 months = $0.21 per hr. × 840 hours = $176.4

h = shift left or right

k = shift up or down.

Answer:

Step-by-step explanation:

Formula : ( surface area of a cone )_________________________

The total surface area = The curved surface area + area of the base

____________________________________________________

→The curved surface area = π × r × g = π × r × (√(h2 + r2))

 where g is the slant height of the cone and r is the radius of the base

 and h is the height of the cone

 and g = √(h2 + r2)

→Area of the base = π × r²

We get :

The curved surface area = π × r × (√(h2 + r2))

                                         = π × 5.1 × √(14^2+(5.1)^2)

                                         = 238.729625746288                                        

Area of the base = π × r²

                            = π × (5.1)^2

                            = 81.712824919871

Conclusion:

The total surface area = The curved surface area + area of the base

                                     = 238.729625746288 + 81.712824919871

                                     = 320.442450666159

The value that can take the place of "?" is -6a. The length of line AB is 6a units.

The distance or length of any line on the graph,

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where,

d = distance/length of the line between point 1 and 2,

(x₁ , y₁) = coordinate of point 1,

(x₂ , y₂) = coordinate of point 2,

The length of a line with two points known is written as,

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Given the coordinate of points A and B are (-3a,b) and (-3a,b), respectively. Therefore, the length of the line AB can be written as,

[tex]AB = \sqrt{(-3a-3a)^2+(b-b)^2}\\\\AB = \sqrt{(-6a)^2+(0)^2}\\\\AB = 6a[/tex]

Hence, the length of line AB is 6a units.

Answer:

Step-by-step explanation:

If the first cube lands on a 4, then the second cube must land on 4 5 or 6.

It cannot land on 5 because that would make it the sum odd. (4 + 5 = 9)

So that leaves 4 and 6. You cannot use 2 because 4 + 2 = 6. The sum must be greater than 6.

So we are left with 2 results. The second cube should be 4 or 6

The results are 4 and 4

Answer:

Option D: 20km South

Step-by-step explanation:

Lets say A = (0, 0)

A is 30km East of D which makes D = (-30, 0)

D is 10km South of F which makes F = (-30, 10)

F is 10km West of B which makes B = (-20, 10)

A is 10km North of C which makes C = (0, -10)

C is 20km East of E which makes E = (-20, -10)

Find distance from B = (-20, 10) to E = (-20, -10)

     1. Cancel equivalent values:

x of B = (-20) and x of E = (-20)

Remove x from equation.

     2. Solve for answer:

B = 10 and E = (-10)

Find the difference: (-10) - 10 = (-20)

Conclusion:

South translates to negative on a graph making the answer 20km South

Answer:

21

Step-by-step explanation:

The pattern goes +5 , -2

From 7 you add 5, and than from 12 you minus 2. If you keep this up you get the following numbers.

7,12,10,15,13,18,16,21,19,24,22,27,25,30...ect

21 is the 8th term in the patterns so thats your answer.

The eighth term in the given number pattern is 21. This is obtained by the logic, of adding 5 and subtracting 2.

These keep a relationship between a series of numbers. That relationship is given by logic.

Some of the examples are like Even number pattern, Odd number pattern, Fibonacci series, etc.

Given that the number pattern is 7,12,10,15,13....

In this pattern 7 is the first term

So, the logic is adding 5 and subtracting 2

7+5=12 (2nd term)

12-2=10 (third term)

10+5=15 (fourth term)

15-2=13 (fifth term)

13+5=18 (sixth term)

18-2=16 (seventh term)

16+5=21 (eighth term)

Therefore, the eighth term is 21.
