A certain refrigerator requires 170 watts of electricity when it is running. It typically runs about 20 minutes per hour. How mu
Xelga [282]

If  certain refrigerator requires 170 watts of electricity when it is running. It typically runs about 20 minutes per hour. The amount it cost to run this refrigerator for one year if the cost per kWh is $0.11 is:  $53.856.

<h3>Cost</h3>

Given:

Electricity watts = 170 watts

Minutes run = 20 minutes

Cost per KWh =$0.11

Hence,

170 watts = 1.7×10^-1

20 min = 1/3 h

Now let calculate the cost of running the refrigerator for one year  

1.7×10^-1 × 1/3 × 24 ×360 × $0.11

= $53.856

Therefore If  certain refrigerator requires 170 watts of electricity when it is running. It typically runs about 20 minutes per hour. The amount it cost to run this refrigerator for one year if the cost per kWh is $0.11 is:  $53.856.

Select all of the angles that are congruent to &lt;5 plzzz helppp​
kirill115 [55]

Answer:

Options A, D and F

Step-by-step explanation:

From the picture attached,

lines 'l' ad 'm' are the parallel lines and line 't' is a transversal intersecting each line at two different points.

From the angles formed at the points of intersection,

∠5 ≅ ∠8 [Vertical angles]

∠5 ≅ ∠4 [Alternate interior angles]

∠5 ≅ ∠1 [Corresponding angles]

Therefore, Options A, D and F will be the correct options.

What are the solution points for the system graph?
JulsSmile [24]

The solution points to the system graph are (–2,–4) and (4,8). Therefore, option A is correct.

We need to find the solution to the given function.

<h3>How to find the solution to the function from the graph?</h3>

The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be at the point where the two lines intersect.

From the given graph we can see that the two functions are intersecting at (–2,–4) and (4,8).

The solution points to the system graph are (–2,–4) and (4,8). Therefore, option A is correct.
