Jim had 3,067.48 in his checking account he wrote a check to pay for two airplane tickets. His account now has 1,845.24.
spayn [35]
Jim started out with 3,067.48 in his checking and ended with 1,845.24 after paying for airplane tickets. To figure out how much money he spent on the tickets, you will need to first subtract the ending amount of 1,845.24 from 3,067.48 and then divide the sum to get the amount spent on each ticket.

3,067.48 - 1,845.24 = 1,222.24
1,222.24\2= 611.12

In the end Jim spent 1,222.24 in total on tickets. He spent around 611.12 on each ticket.

Hope this helps!

Nikki works at a store that sells consumer electronics. She earns $12 per hour, plus a commission of 5% of her total sales amoun
Mazyrski [523]

Answer:

See below.

Step-by-step explanation:

So, Nikki earns $12 per hour.

And she also earns a 5% or 0.05 commission of her total sales each day.

On Saturday, she worked eight hours and she earned $139. In other words, she earned 8(12) or $96 from working her hours and another $43 (139-96) from her commission.

Thus:

139=96+0.05x

Where x represents Nikki's total sales on Saturday.

Further notes:

To solve, subtract 96 from both sides and divide by 0.05:

139=96+0.05x\\43=0.05x\\x=\$860

Thus, her total sales that day were $860.

Tan^2theta - Sin^2theta = tan^2theta. sin^2theta <br> explain this step<br>​
denis23 [38]

tan²(<em>θ</em>) - sin²(<em>θ</em>) = sin²(<em>θ</em>)/cos²(<em>θ</em>) - sin²(<em>θ</em>)

-- because tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>) by definition of tangent --

… = sin²(<em>θ</em>) (1/cos²(<em>θ</em>) - 1)

-- we pull out the common factor of sin²(<em>θ</em>) from both terms --

… = sin²(<em>θ</em>) (1/cos²(<em>θ</em>) - cos²(<em>θ</em>)/cos²(<em>θ</em>))

-- because <em>x</em>/<em>x</em> = 1 (so long as <em>x</em> ≠ 0) --

… = sin²(<em>θ</em>) ((1 - cos²(<em>θ</em>))/cos²(<em>θ</em>))

-- we simply combine the fractions, which we can do because of the common denominator of cos²(<em>θ</em>) --

… = sin²(<em>θ</em>) (sin²(<em>θ</em>)/cos²(<em>θ</em>))

-- due to the Pythagorean identity, sin²(<em>θ</em>) + cos²(<em>θ</em>) = 1 --

… = sin²(<em>θ</em>) tan²(<em>θ</em>)

-- again, by definition of tan(<em>θ</em>) --
