Answer:
10c + 1200 ≥ 3000, c≥ 180
Step-by-step explanation:
We know that they need at least $3000; meaning, it may be $3000 or more. This leaves us with eliminating the bottom two choices.
We then look at the first two choices. If we were to subtract from 1200, we would not know the total income amount that has been gained. It would also eventually give us negative numbers. We cannot have a negative amount earned. Instead, we would use the 10c+1200 because this would allow us to visualize that it needs to be greater than or equal to 3000
Answer:
5. 34°
6. 29.7
Step-by-step explanation:
5. Using sine law
25/sin(93) = 14/sin(C)
sin(C) = 0.5592325395
C = 34.00273934°
6. Using cosine law
AC² = 23.2² + 18.1² - 2(23.2)(18.1)cos(91)
AC² = 880.507229
AC = 29.67334206
I would add like terms, meaning subtract 6.4 from both sides.
3.5n = 36.1
Answer:
its 15.43
Step-by-step explanation:
you didnt put a picture for the polygons but im pretty sure this is from math nation.
A) set x as the number of cameras
18x=9x+1800
9x=1800
x=200
b) i'm assuming it's increasing production from my answer in a, so the profit would be 18(250)-(9*250+1800)=4500-4050=450
