8. A ship leaves port at 9:00 a.m. and has a bearing of N 70° W. The ship sails
at 18 knots. How many nautical miles north and how many nautical miles
west will the ship have traveled by 1:00 p.m.? Draw a picture!
Round to the nearest tenth.
9514 1404 393
Answer:
24.6 Nm north67.7 Nm westStep-by-step explanation:
In x-y coordinates, the direction is 70° CCW from 90° (north), so is 160° from the +x axis. In 4 hours at 18 Nm/h, the ship will travel 4×18 Nm = 72 Nm.
The coordinates in the x-y plane can be found to be ...
72(cos(160°), sin(160°)) ≈ (-67.7, 24.6)
The ship traveled 67.7 nautical miles west and 24.6 nautical miles north from the port.

Step-by-step explanation:
Lunches can be made consisting of exactly one entrée, one drink, and one snack. If all lunch options are equally likely, what is the probability of randomly choosing a lunch that
does not contain the veggie wrap
has milk or water, and
has fruit as the snack.
Write your answer as a percentage, to the nearest percent.
Entrée Chicken Cutlet Veggies Wrap Lasagna
Drink Milk Water Iced Tea
Snack Fruit Chips Jello
%
Answer:
4/27=14.8%
Step-by-step explanation:
In order to solve this, we have to see first each option possible, there are 2/3 of possibilities that a random Entrée ends up being Chicken Cutlet or Lasagna, then you have again 2/3 chances to get milk or water, and as you only want fruit the chances are 1/3 that you get that.
In order to calculate if this could happen at random we have to multiply all of the odds:
[tex]Probability: \frac{2}{3} *\frac{2}{3} *\frac{1}{3} \\Probability: \frac{2*2*1}{3*3*3} \\Probability: \frac{4}{27}[/tex]
So we know that for every 27 times you pick a lunch at random, 4 times it will not have the Veggie Wrap, contain milk or water, and will have fruit as the snack.
There are 2/3 of possibilities that a random Entrée ends up being Chicken Cutlet or Lasagna, then you have again 2/3 chances to get milk or water, and as you only want fruit the chances are 1/3 that you get that.
We need to now multiply the odds:
2/3x2/3x1/3
2x2x1/3x3x3
4/27
So we know that for every 27 times you pick a lunch at random, 4 times it will not have the Veggie Wrap, contain milk or water, and will have fruit as the snack.
So now we know it is, %15 rounded but 14.8% not rounded.
If f(x) = 3(x+ 5) +4/x, what is f(a+2)?
A. 3(f (a) + 5) +4/f(a)+2
B. 3(a + 7) + 4/a+2
C. 3(a + 2) + 4/a + 2
Answer:
B. 3(a + 7) + 3/(a + 2)
Step-by-step explanation:
Just substitute (a+2) in for every (x) in the equation:
f(a + 2) = 3 ((a + 2) + 5) + 4/(a+2)
= 3 (a + 7) + 4/(a+2)

tomas works for a cellphone company. he has a base salary of $350 each month and earns an additional $40 for each cellphone he sells. write a function (linear equation) in slope-intercept form (y = mx + b) that represents tomas' total earnings (y) for one month for selling (x) number of cellphones.
Use the linear equation from question 1 to determine Tomas' earnings for a month where he sold 30 cellphones. *
Answer:
The function is [tex]y = 40x + 350[/tex]
When he sold 30 cellphones, he earned $1550.
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope(how much y changes when x changes by 1), and b is the y-intercept, that is, the value of w when x = 0.
Base salary of $350 each month and earns an additional $40 for each cellphone he sells.
If he sells 0 cellphones, he earns $350, so [tex]b = 350[/tex].
For each cellphone he sells, he earns $40, so [tex]m = 40[/tex]
The function is:
[tex]y = mx + b = 40x + 350[/tex]
Tomas' earnings for a month where he sold 30 cellphones.
This is y when [tex]x = 30[/tex]. So
[tex]y = 40*30 + 350 = 1550[/tex]
When he sold 30 cellphones, he earned $1550.
Which equation represents the relationship between the x-values and the y-values in the table?
Answer:
y = 10x + 5
Step-by-step explanation:
Remember when x = 0 that is when you get your y-intercept. So when you look at the chart you can see that your answer has to have a +5 so now you are down to only to answers.
Now slope is the change of Y over the change of X , so 5 to 55 is 50
and 0 to 5 is 5
[tex]\frac{y}{x}[/tex]=[tex]\frac{50}{5}[/tex] and that equals 10
put both parts together and
y = 10x + 5
