A ferry transports passengers to three different ports. From port 1, the ferry travels east 3.5 miles to port 2. The ship
then heads 15 east of south for 6 miles to reach port 3. What is the distance from port 3 to port 1? Draw a diagram to
help you. Approximate to the nearest tenth of a mile.
miles
Answer:
7.7
Step-by-step explanation:
trust me, I solved it out
Answer: The distance between port 3 to port 1 is 7.7 miles.
A rough sketch is attached.
The angle between 3.5 and 6 is = (90 + 15) = 105 degrees.
We will need the law of cosine.
So the distance between port 3 to port 1 is:
[tex]\sqrt{3.5^{2}+6^{2}-2\left(3.5\right)\left(6\right)\cos\left(105\right)}=7.68897911912=7.7[/tex].

Answer:
x = 8
Step-by-step explanation:
x - 8/2 = 4
Follow your order of operations and divide first.
8/2 is 4
x- 4 = 4
Next, isolate the variable by using the additive property of equality.
x - 4 + 4 = 4 + 4
x = 8
Answer:
ok so u do the opposite of 8/2 so do 8*2 which is 16 then add the answer which is 4 which equals 20 so 20- 8/2=4, 20-16=4

100 trout are seeded into a lake. Absent constraint, their population will grow by 70% a year. The lake can sustain a maximum of 2000 trout. How many trout will be in the lake after 2 years.
After 2 years, the population of trout in the lake will be 2000 trout.
Given:
Initial population = 100
Growth rate = 70%
Time= 2 years
After the first year:
Population after 1 year = Initial population + (70% of the initial population)
= 100 + (0.7 * 100)
= 100 + 70
= 170 trout
After the second year:
Population after 2 years = Population after 1 year + (70% of the population after 1 year)
= 170 + (0.7 * 170)
= 170 + 119
= 289 trout
Since the calculated population exceeds this limit, the population will be limited to the maximum capacity of 2000 trout.
Therefore, the population of trout in the lake will be 2000 trout.

Who ran the fastest? Explain how this is shown on the graph and in the tables?
Answer:
1) Please find attached the distance and speed time graphs
2) Please find attached the distance time tables
3) The fastest runner is Jason, as shown by the topmost line in the graphs
4) On the tables Jason is seen to have covered 400 meters in one minute, while Patti covered 300 meters and Quincy covered in the same one minute time interval
Step-by-step explanation:
The given speed of the runners are;
The rate at which Patti ran = 300 meters in 60 seconds
The rate at which Jason ran = 500 meters in 1.25 minutes
The rate at which Quincy ran = 600 meters in 2 minutes and 30 seconds
The formula for speed is given as follows;
Speed = Distance ran/(Time to cover the distance)
Therefore, the speed of each of the runners are;
Patti's speed = 300 m/(60 seconds) = 300 m/(1 minute) = 300 m/min
Jason's speed = 500 m/(1.25 minute) = 400 m/min
Quincy's speed = 600 m/(2 minutes and 30 seconds) = 600 m/(2.5 minutes)
∴ Quincy's speed = 240 m/min
Therefore, we have
1) The distance and speed time graphs are attached
2) The distance time tables are attached
3) The fastest runner is Jason, as shown by the topmost line in the graphs
4) The fastest runner is Jason as seen by the covered distance of 400 meters in one minute.
Which statements are true? Select 3 options
if the width is 8 less than the length of a rectangle and the perimeter is 48 find the width
Answer:
Widyh = 8 units
Step-by-step explanation:
Perimeter = 2/width+length)
then:
48 = 2(W+L)
W = L-8
W = Width
L = Length
then:
48 = 2((L-8)+L)
48 = 2(2L88)
48 = 2*2L - 2*8
48 = 4L - 16
48 + 16 = 4L
64 = 4L
L = 64/4
L = 16
W = L-8
W = 16-8
W = 8
Check:
48 = 2(16+8)
48 = 2*24
Nora took 10 bottles of water to a picnic. Of these bottles of water, she and her friends opened a certain number of bottles, b. What expression can be used to determine the number of unopened bottles at the end of the picnic?
Answer:
10 - B = U
Step-by-step explanation:
U stands for the unopened bottles
for example if they opened 3 bottles it would be 10 - 3 = U (unopened bottles)
The value of U is 7 because the 10 bottles of water minus the 3 bottles they opened it would equal 7.
therefore the equation 10 - B = U shows the amount of unopened bottles

carries family broke a package of graham crackers into 32 pieces. carries two brothers each ate 1/8 of the pieces and the rest of the family ate 7/16 of the pieces.
carries two brothers each ate ____ pieces
the rest of carries family ate ____ pieces
there were ____ pieces remaining
Answer:
Carrie's two brothers each ate 4 pieces, and the rest of the family ate 14 pieces, there were 10 pieces left.
Step-by-step explanation:
First, change all of the fraction's denominators into 32:
1/8 = 4/32
7/16 = 14/32
This gives us the answer to the first two questions.
Then add up the amount of pieces each person ate. Carrie has two brothers, so we double 4/32, which gives us 8/32. 8/32 + 14/32 = 22/32.
32 - 22 = 10, so there are 10 pieces remaining.
Hope this helps!
Answer:
Carries two brothers ate 4 pieces.
The rest of Carries family ate 14 pieces.
There were 14 pieces remaining.
Step-by-step explanation:
To find out how much the brothers ate you can divide 32 by 8 to get 4. For the family you can turn 7/16 into 32nds
16 x 2 = 32 and 7 x 2 = 14
so the family ate 14 pieces. Add 14 + 4= 18 so that's how much they all ate in total then 32-18 = 14. That means 14 pieces are left.
Hope that helps and have a great day!

Evaluate f(2) for the function f(x) = 3x2 + 2x - 5
Answer:
The answer for f(2) is 11.
Step-by-step explanation:
f(x) = 3x2 + 2x - 5
f(2) = 3(2)2 + 2(2) - 5
f(2) = 6(2) + 4 - 5
f(2) = 12 + 4 - 5
f(2) = 16 - 5
f(2) = 11
The value of f(2) is 11 and this can be determined by using the arithmetic operations and the given data.
Given :
[tex]\rm f(x) = 3x^2+2x-5[/tex]
The following steps can be used in order to determine the value of f(2):
Step 1 - Write the given function.
[tex]\rm f(x) = 3x^2+2x-5[/tex]
Step 2 - The arithmetic operations can be used in order to determine the value of f(2).
Step 3 - Now, substitute the value of (x = 2) in the given function.
[tex]\rm f(2) = 3(2)^2+2(2)-5[/tex]
Step 4 - Simplify the above expression.
[tex]\rm f(2) = 3\times 4+4-5[/tex]
f(2) = 12 - 1
f(2) = 11
