33.4 kW/ hr is generated when the sky is cloudy and clear.

<u>Step-by-step explanation:</u>

Power generated per day when the sky is cloudy = 400 kW

Power generated per day when the sky is clear = 400 kW

Power generated per hour when the sky is cloudy or clear = $\frac{400}{24} = 16.7 kW

Power generated per hour when the sky is cloudy and clear = 16.7 + 16.7 = 33.4 kW

Which of the following is an arithmetic sequence?
arsen [322]

Answer:

Here are a few lists of numbers:

3, 5, 7 ...

21, 16, 11, 6 ...

1, 2, 4, 8 ...

Step-by-step explanation:

Ordered lists of numbers like these are called sequences. Each number in a sequence is called a term.

3,3,3, comma 5,5,5, comma 7,...7,...7, comma, point, point, point

\uparrow↑\uparrow \uparrow↑\uparrow \uparrow↑\uparrow

\footnotesize 1^\text{st}\text{ term}1

st

 term1, start superscript, start text, s, t, end text, end superscript, start text, space, t, e, r, m, end text \footnotesize 2^\text{nd}\text{ term}2

nd

 term2, start superscript, start text, n, d, end text, end superscript, start text, space, t, e, r, m, end text \footnotesize 3^\text{rd}\text{ term}3

rd

 term3, start superscript, start text, r, d, end text, end superscript, start text, space, t, e, r, m, end text

Sequences usually have patterns that allow us to predict what the next term might be.

For example, in the sequence 3, 5, 7 ..., you always add two to get the next term:

\footnotesize\maroonC{+2\,\Large\curvearrowright}+2↷start color #ed5fa6, plus, 2, \curvearrowright, end color #ed5fa6  \footnotesize\maroonC{+2\,\Large\curvearrowright}+2↷start color #ed5fa6, plus, 2, \curvearrowright, end color #ed5fa6  

3,3,3, comma  5,5,5, comma  7,...7,...7, comma, point, point, point

Solve the system of equations 2y - 3x = -27 5y + 3x = 6 PLEASE EXPLAIN STEPS! <br> (photo included)
Solnce55 [7]

Answer:

(7, -3)

Step-by-step explanation:

Add the two equations to eliminate x:

7y = -21

Then solve 7y = −21 for y:

\frac{7y}{7} = \frac{-21}{7}(<em>Divide both sides by 7)</em>

y = -3

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

2y - 3x = -27

Substitute -3 for y in 3y - 3x = -27:

(2)(-3) - 3x = -27

-3x - 6 = -27 (<em>Simplify both sides of the equation</em>)

-3x - 6x + 6x = -27 + 6 (<em>Add 6 to both sides</em>)

-3x = -21

\frac{-3x}{-3} = \frac{-21}{-3} (<em>Divide both sides by -3</em>)

x = 7
