Answer: A) yes,B)4.50n<105
Step-by-step explanation: should would make profit because you would take the answer you got from 12n > 105 + 4.50n to see work look below
12-4.50=7.5
7.5n>105
7.5/135=0.5
18*15=270
the answer for part b would be to see work look below
set up equation(4.50n<105)
4.50/105
answer is n<.042
Hope I <em><u>Helped!</u></em> :D
Answer: 0.88
============================================
Work Shown:
sine is the ratio of the opposite over hypotenuse
sin(angle) = opposite/hypotenuse
sin(I) = GH/IG
sin(I) = 15/17
sin(I) = 0.88235 approximately
sin(I) = 0.88
Item Time bought
MIcroscopes Every 5 years
Safety goggles Every 4 years
Test Tube Every 2 years
It would take 20 years for them to buy these three items at the same time.
We simply need to find the LCM or least common multiple of the 3 items using the number of years.
Microscopes - 5 years → 5, 10, 15, 20
Goggles - 4 years → 4, 8, 12, 16, 20
Test tubes - 2 years → 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
2016^2016 = 2^10080 * 3^ 4032 * 7^2016
so the answer is 1
