A boat sails on a bearing of 73 degrees for 128 miles and then turns and sails 209 miles on a bearing of 190 degrees. Find the distance of the boat from its starting point.
Answer:
189.14 miles.
Step-by-step explanation:
This is a vector problem.
A boat sails on a bearing of 73°. This means it is going north, forming a 90° triangle.
The sum of angles in a triangle = 180°
We need to find the third angle.
180° = 90° + 73° + x°
x° = 180° - (90 + 73) °
x = 180° - 163°
x = 17°
The boat then turns and sails 209 miles on a bearing of 190 degrees.
Since it is sailing 190°, it is sailing more than 180°
= 190° - 180° = 10°
This would lead to the formation of another triangle let us call it ABC
Hence, we would have:
90° - ( 10 + 17)°
90° - 27° = 63°
To find the distance of the boat, we would use Cosine rule.
a² = b² + c² - 2bc × Cos A
a = √(b² + c² - 2bc × Cos A
b = 128 miles
c = 209 miles
A = 63°
a = √(128² + 209² -2 × 128 × 209 × Cos 63°)
a = 189.14199miles
Approximately 189.14 miles.
Therefore, the distance of the boat from it's starting point is 189.14 miles.

Answer:
[tex]\Large \boxed{\mathrm{12. \ 54}}[/tex]
[tex]\Large \boxed{\mathrm{13. \ -7.6}}[/tex]
Step-by-step explanation:
|54|
Solve for absolute value.
Apply rule : |a| = a
|54| = 54
-|-7.6|
Apply rule : |-a| = a
-|-7.6| = -7.6
Answer:
12: 54 and 13: -7.6
Step-by-step explanation:
The absolute value of a number is basically the distance it is from 0. For example, |1| = 1. There is a "rule" for absolute value, if a number x ≥ 0, then |x| = x but if x < 0, then |x| = -x. This is because absolute value is always positive, and if a number is negative, all you have to do to make it positive is multiply it by -1. Therefore, the answer for 12 is 54 since x > 0 in this case. To find the answer to 13, we know that |-7.6| = -(-7.6) = 7.6. -(7.6) = -7.6.

Answer:
8 roses and 12 carnations.
Step-by-step explanation:
For this question, we can use substitution.
r + c = 20, so r = 20 - c.
Substitute this into the second equation, and we get (0.75)(20 - c) + 0.5 c = 12
We can expand, getting 15 - 0.75c + 0.5c = 12.
Combine like terms, and we get 0.25c = 3.
We then solve for c: 12.
Plug this back into the first equation, and we get r = 8.
There are 8 roses and 12 carnations in Denny's bouquet.

On a number line, suppose the coordinate of A is 0 and AR=21. What are the possible coordinates of the midpoint of AR?
Answer:
The possible coordinates of the midpoint are -10.5 and 10.5
Step-by-step explanation:
The given parameters are;
The coordinate of A = 0
The distance from A to R which is the same as AR = 21
Given that R is on the number line, we have;
When R is on the left side of A, which is = 0 - 21 = -21, we have;
The coordinates of the midpoint, M from -21 to 0 is given as follows;
M = (A + R)/2 = (0 - 21)/2 = -10.5
When R is on the right side of A, which is = 21 - 0 = 21, we have;
The coordinates of the midpoint, M from 21 to 0 is given as follows;
M = (A + R)/2 = (0 + 21)/2 = 10.5
Therefore, the possible coordinates of the midpoint are -10.5 and 10.5.

Answer:
all real numbers
Step-by-step explanation:
simplify each side of the inequality
26 + 6b -- already fully simplified
2(3b + 4) → 6b + 8
26 + 6b ≥ 6b + 8
subtract 6b from both sides
26 ≥ 8
since this expression is true (26 is greater than 8), then the solution is all real numbers. any value could take the place of b because in the end, it will be canceled out by itself, resulting in 26 ≥ 8
Enter the value for x that makes the given equation true.
2(-2x - 4) + 6 = 5 – 3(x + 1)
Answer:
Step-by-step explanation:
-4x - 8 + 6 = 5 -3x - 3
-4x - 2 = -3x + 2
-x - 2 = 2
-x = 4
x = -4
For the expression 2(-2x - 4) + 6 = 5 – 3(x + 1) the value of x is -4.
What is algebra?Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.
The given expression is,
2(-2x - 4) + 6 = 5 - 3(x + 1)
To find the value of x, simplify the expression,
-4x - 8 + 6 = 5 - 3x - 3
-4x - 2 = 2 - 3x
-4 = 4x - 3x
x = -4
The required value of x is -4.

jimmy cn run 3.5 miles in 20 minutes. How far can he run in one hour and ten minutes?
Answer: 12.25miles.
Step-by-step explanation:
This is a simple proportion.
20 miles = 3.5miles
∴ 1 mile = 3.5/20
∴ 1hour 10minutes which is equivalent to 70minutes will be

A 700 g dry fruit pack costs ₹216 .It contains some almonds and the rest cashew kernel.If almonds cost ₹288 per kg and cashew kernel cost ₹336 per kg what are the quantities of the two dry fruits separately?
Answer:
Almonds = 400grams
Cashew = 300 grams
Step-by-step explanation:
Let the grams of cashew be represented by = C
the grams of almonds be represented by = A
A 700 g dry fruit pack costs ₹216 .It contains some almonds and the rest cashew kernel
C + A = 700g ......Equation 1
C = 700 - A
If almonds cost ₹288 per kg and cashew kernel cost ₹336 per kg
Let's convert them to grams
1 kg = 1000grams
For almonds
= 288/1000 = 0.288g
For cashew
= 336/1000 = 0.336g
Hence,
0.288 × A + 0.336g × C = ₹216
0.288A + 0.336C = 216
From Equation 1, substitute 700 - A for C in Equation 2
0.288A + 0.336(700 - A) = 216
0.288A + 235.2 - 0.336A = 216
Collect like terms
0.288A - 0.336A = 216 - 235.2
- 0.048A = -19.2
A = -19.2/-0.048
A = 400 grams
Substitute 400g for a in Equation 1
C + A = 700g ......Equation 1
= C + 400g = 700g
C = 700g - 400g
C = 300g
Therefore, the number of grams of Almonds = 400grams
Cashew = 300 grams

3x < -7-2 .... subtract 2 from both sides
3x < -9
x < -9/3 .... divide both sides by 3
x < -3
Do the same for the second inequality
-4x+5 < 1
-4x < 1-5
-4x < -4
x > -4/(-4) .... note the inequality sign flips
x > 1
So either x < -3 or x > 1. This points to choice A as the answer.

f(x) = (x + 2)^2 - 16 Enter the solutions from least to greatest.
Answer:
-6,2
Step-by-step explanation:
f(x) = (x + 2)^2 - 16
Set this equal to zero to find the solutions
0 = (x + 2)^2 - 16
Add 16 to each side
16 = (x + 2)^2
Take the square root of each side
±sqrt(16) = sqrt( (x + 2)^2)
±4 = x+2
Subtract 2 from each side
±4 -2 = x+2-2
±4 -2 = x

john receives a day worth of pay, p, for 4 days of newspaper delivery. He spent half of his money on gas. Then he spent 5$ on coffee. He now has 35$ left. How much does John get paid each day for newspaper delivery?
Answer:
Let's assume John gets p for each day so his total is 4p. He spends half of that on gas, (4p)/2 = 2p. He has 2p left. Now subtract 5 from 2p for the coffee, and there is 35 left. So 2p - 5 = 35. Right? Now you can solve for p, by simplifying that equation.

Order from least to greatest using number line
First, we have to order the temperatures:
In order from least to greatest, we have: -3°C -1°C 0°C 2°C 5°C
Next, we calculate the range;
Range = Highest - Least
Range = 5°C - 3°C

Please Help, I Really Need The Answer To This Question
Answer: y < (-1/4)*x + 1.
Step-by-step explanation:
The first thing you need to notice is that the line is not solid and that the shaded part is under the line, so our inequality will be strictly smaller than a linear equation.
y < a*x + b.
Now let's find the equation of the line.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
In the graph, we can see that the line passes through the points: (0,1) and (4. 0)
Then the slope is:
a = (0 - 1)/(4 -0) = -1/4.
Now we know that the line is:
y = (-1/4)*x + b
To find the value of b, just replace the value of one of the points in the equation.
We know that (0,1) is a solution of the equation (x= 0, y = 1)
1 = (-1/4)*0 + b = b
1 = b
Then our inequality is:
y < (-1/4)*x + 1.

Answer:
y = 6
Step-by-step explanation:
Given a parallelogram ABCD with diagonals AC and BD.
Kindly refer to the diagram attached for the given parallelogram.
[tex]AE=2x\\BE=y+10\\CE=x+2\\DE=4y-8[/tex]
To find:
The value of y = ?
Solution:
First of all, let us consider a property of parallelogram and its diagonals.
The intersecting point of diagonals of a parallelogram bisect the diagonals in two equal parts.
Let us consider the given parallelogram ABCD which has its diagonals BD and AC intersecting at point E.
As per the property stated above:
AE = CE and
DE = BE
Putting the values of AE, CE, DE and BE as given in the question statement and solving for [tex]x[/tex] and [tex]y[/tex]:
[tex]2x = x+2\\\Rightarrow \bold{x = 2}[/tex]
and
[tex]y+10=4y-8\\\Rightarrow 4y-y = 10+8\\\Rightarrow 3y=18\\\Rightarrow y =\dfrac{18}{3}\\\Rightarrow \bold{y= 6}[/tex]
So, the answer is:
y = 6
