-t + 9t - 12t - (-16t) - 18t = -6
-t + 9t - 12t + 16t - 18t = -6
-6t = -6
-6t/-6 = -6/-6 (-6 on the left side cancels out so we are only left with T and our answer)
T = 1
Answer:
more than 200 calls
Suppose number of calls = x
According to plan 1: Total monthly charge is $24
According to plan 2: Fix charge is $16 and $0.04 per call
cost of x's call = $0.04x
and monthly charge according to plan 2 = 0.04x + 16
a) Plan 1 is more economical than plan 2.
0.04x + 16 > 24
solve it for x
.04x > 8
x > 200
b) So, if more than 200 calls are made then Plan 1 is more economical.
Step-by-step explanation:
Since the bucket has already a mass of 2,000 kg, therefore
the maximum mass of gravel would only be:
15,000 kg – 2,000 kg = 13,000 kg gravel
Solving for volume:
volume = 13,000 kg / (1,500 kg / 1 m^3)
volume = 8.67 m^3
<span>Therefore about 8.67 cubic meter of gravel can be safely
loaded by the crane.</span>
That would be.... placoderm fish
It is equal to 100 ft longer
