Answer:
sin Z = 9 / 15
cos Z = 12 / 15
tan Z = 9 / 12
Step-by-step explanation:
opposite of Z = 9
adjacent of Z = 12
hypotenuse = 15
sin = opp / hyp
so sin Z = 9 / 15
cos = adj / hyp
so cos Z = 12 / 15
tan = opp / adj
so tan Z = 9/12
Answer:
12
Step-by-step explanation:
Multiply both sides of the equation by 8/5.
4x-16=32
Move 16 to the other side
4x=32+16
add numbers on the right side
4x=48
divide both sides by 4
x=12
<u>40% of 300 </u>
<u>=300×(40/100) </u>
<u> [As40 percent means 40 out of hundred, so we need to multiply the fraction]</u>
<u>=3×40</u>
<u>=120 </u>
<h3><u>
40% of 300 =120 So 120 students choose conserving natural resources.</u></h3><h3><u>
</u></h3><h2><u>
2.</u></h2>
<u>Now 24% choose conserving natural resources ,</u>
<u>24% of 300</u>
<u>=300(24/100)</u>
<u>=3×24</u>
<h2><u>
=72</u></h2><h3><u>
So 72 students choose conserving natural resources.</u></h3>
The answer to this answer choice is A. (45x12)+75=c
It raised $1.30
1.30/13.15 = .098
It raised 9.888%
