You first divide 40 by 19:
19/40=?
Then you convert that to percentage by dropping the decimal point and attaching a %
(hint: you should get 48% about :)
Answer: Nicole can spend up to 7 hours in the boat.
Step-by-step explanation:
Based on the information given in the question, the possible number of hours that can be used will be calculated as thus:
(6 × t) - 9 ≤ 33
6t - 9 ≤ 33
Collect like terms
6t ≤ 33 + 9
6t ≤ 42
Divide both side by the coefficient of t
6t/6 ≤ 42/6
t ≤ 7
Nicole can spend up to 7 hours in the boat.
Answer: y = 3x - 5.322
Step-by-step explanation:
The standard format for an equation of a straight line is y=mx+b, where m is the slope and b is the y-intercept.
We can say y = 3x + b, but then need to add the one given point to calculate b.
y = 3x + b for (1.7, -2/9) is:
-2/9 = 3(1.7) + b
b = -5.322
The line is y = 3x - 5.322
