' 36 = 9k ' is not an inequality.  It's an <u>equality</u>, usually called an <em><u>equation</u></em>.

It's true whenever 'k' is 4, and false at any other time.

(You can determine that simply by dividing each side of the equation by 9.)

1. Alex bought 2 buckets of baseballs that cost $19.49 each, a bat that cost $125.50, and 2 pair of baseball socks that totaled
Blizzard [7]

Answer:

$90.02

Step-by-step explanation:

<u>Solve</u>

Formula: Change money = paid money – bill. Paid money = change + bill.

Given: <em>2</em> buckets of baseballs that cost $<em>19.49</em> each

A bat that cost $<em>125.50</em>, and <em>2</em> pairs of baseball socks that totaled $<em>29.50</em>

Tax on Alex's purchases equaled $<em>16</em>.

Paid with three $<em>100</em> bills.

To find: How much change Alex received if he paid with three $100 bills

Total payment + Total Tax  -Total cost

19.49 + 125.50 + 29.50  = 174.49 (Don't add the $16 tax because that will be taken from the amount we pay)

∴, <em>three </em>100 bills is 300

So, 300 - 174.49 = 109.51

109.51 - 16 = 90.51

90.51 - 0.49 = $90.02

SOLUTION

Step 1: Find the area of the wall.

\begin{gathered} A=l\times b \\ A=42\times25.5 \\ A=1071ft^2 \end{gathered}

Step 2: Find the cost of wallpaper per square foot

=\frac{total\text{ cost of wallpaper}}{Area\text{ of the wall}}\begin{gathered} =\frac{771.12}{1071} \\ =0.72\text{ dollars} \end{gathered}

The correct answer is B: $0.72

I need help breaking this down
sergeinik [125]

Answer:

see explanation

Step-by-step explanation:

Given

2cosΘ - \sqrt{2} = 0 ( add \sqrt{2} to both sides )

2cosΘ = \sqrt{2} ( divide both sides by 2 )

cosΘ = \frac{\sqrt{2} }{2}

Since cosΘ > 0 then Θ is in first and fourth quadrants, hence

Θ = cos^{-1} ( \frac{\sqrt{2} }{2} ) = \frac{\pi }{4}

OR

Θ = 2π - \frac{\pi }{4} = \frac{7\pi }{4}

solutions are Θ = \frac{\pi }{4}, \frac{7\pi }{4}
