Vectors: A boat moves through the ocean on a foggy day. The boat is pointing North and can typically move at a speed of 12.8 m/s in calm waters. The boat travels through water where there is a 5.9 m/s current flowing to the East. What is the speed of the boat relative to a stationary observer on land? __m/s Part 2 The boat turns to face directly West. Now how fast is the boat moving relative to land? __m/s
Answer:
1.) 14.09 m/s
2.) 6.9 m/s
Step-by-step explanation:
Given that the boat is pointing North and can typically move at a speed of 12.8 m/s in calm waters. The boat travels through water where there is a 5.9 m/s current flowing to the East.
The speed of the boat relative to a stationary observer on land will be achieved by using pythagorean theorem
V^2 = 12.8^2 + 5.9^2
V^2 = 198.65
Square root both sides
V = 14.09 m/s
2.) If the boat turns to face directly West.
Since the boat can move at speed 12.8 m/s in a calm water, the speed of the boat if it face west will be
12.8 - 5.9 = 6.9 m/s
Therefore, the boat is moving relative to land at 6.9m/s

use deductive reasoning to write a formula for the perimeter P of a regular polygon with n sides, where each side is s.
Step-by-step explanation:
If each side is s and the regular polygon has n sides, then the perimeter P must be n * s.
Equation for perimeter of regular polygon = ns
Given that;
Number of sides of regular polygon = n
Length of each side = s unit
Find:
Equation for perimeter of regular polygon
Computation:
Perimeter of regular polygon = [Number of sides of regular polygon[[Length of each side]
Equation for perimeter of regular polygon = [n][s]
So,
P = ns

Nia has a membership to Apple Music. She pays $9.99 per month and $0.10 per download. If she spent $10.89 last month, how many downloads did she make last month?
Answer:
9 downloads
Step-by-step explanation:
Let's start by subtracting the initial fee of $9.99 from her total bill of $10.89.
$10.89 - $9.99 = $0.90
Now, let's divide her total cost of downloads by the individual cost of downloads.
$0.90/$0.10 = 9
Nia made 9 downloads last month.

Dale is a software salesman. His base salary is S1800, and he makes an additional S90 for every copy of English is Fun he sells.
Let P represent his total pay (in dollars), and let N represent the number of copies of English is Fun he sells. Write an equation relating P to N. Then use this
equation to find his total pay if he sells 23 copies of English is Fun.
Answer:
P = 90N +1800$3870Step-by-step explanation:
For sales of N copies at $90 each, 90N is added to Dale's base salary of $1800.
P = 90N +1800
__
For N=23, Dale's salary would be ...
P = 90(23) +1800 = 2070 +1800 = 3870
Dale's total pay for selling 23 copies would be $3870.
As the owner of a pastry shop, you decide to have a sale on brownies. You price each brownie at 37 cents. At the end of the sale, you have sold 10 trays of brownies, with 12 brownies in each tray.
How much money did you receive from selling the brownies?
Answer:

10×12= 120 so you would 120 brownie.
so 120 × 37 for each is 4440 so your answer would be 4440. I used desmos.com, it is very helpful. You should give it a try!
Answer:
$44.40
Step-by-step explanation:
Each tray has 12 brownies, And you sold 10 trays
calculate total amount of brownies
10 × 12 = 120 brownies
37 cents = 0.37
multiply them together
120 × 0.37 = 44.40
Thus, you recieve 44.40

Answer:
The ratio of this number to the rectangle’s area is 9:32.
Step-by-step explanation:
The information provided are:
Tom made a square measuring 8 feet by 8 feet.He had 18 friends stand inside it as if they are watching a band at a small club.The area of the square is:
A = (side)²
[tex]=(8\ \text{feet})^{2}\\\\=64\ \text{feet}^{2}[/tex]
The number of people standing insider the square is:
n = 18
Compute the ration of n to A as follows:
[tex]n:A=18:64[/tex]
[tex]=\frac{18}{64}\\\\=\frac{9}{32}\\\\=9:32[/tex]
Thus, the ratio of this number to the rectangle’s area is 9:32.
