Hello there! So, 1/4 is equivalent to 0.25, which is 25% in percent form. 0.5 is 50% and 0.2 is 20% in percent form. 50 + 20 + 25 is 95. 100 - 95 is 5. Issac can use 5% of the minutes on the cell phone plan. The answer is D: 5%.
Answer:
(12 + 3x)x
Step-by-step explanation:
(12 + 3)x = 12x + 3x = 15x
(12 + 3x)x = 12x + 3x²
15x
12x + 3x = 15x
They all equal 15x except for (12 + 3x)x
Since we want to find the value of <em>k</em><em> </em>where the limit exists, set both equations equal to each other. Then substitute <em>x</em> = -1 in for each equation to find <em>k</em><em>.</em>
<em>
</em>
1. Set both equations equal.

2. Substitute <em>x</em><em> </em>= -1.

3. Solve for <em>k</em><em> </em>by adding <em>k</em><em> </em>to both sides. Continue the process of solving the equation.


Thus, <em>k</em><em> </em>= -2. Check by graphing the function.
Answer:
A)4.1%
Step-by-step explanation:
First you need to add all the payments together to get your total.
1400+300+150+800+300+150+100+100+150+200=3650
Then you cross multiply and divide to get the percentage.
=
When you cross multiply and divide x≈4.1
Answer:
<h2><u><em>
x = 18 °</em></u></h2>
Step-by-step explanation:
you have a rotation angle of 360 °, take out the known values (360 ° -90 ° -144 ° = 126), 144 ° is part of a flat angle of 180 °, from 180 ° remove 144 and you have 36 °, they are opposite angles therefore the same. therefore 360 - 144 - 90 - 36 - 36 = 54.
54 is 3x, so x = 18 ° (54 : 3 = 18)
