Complete question :
Scottie is standing next to a lighthouse on the edge of a cliff overlooking the ocean. The cliff is 30 meters above
sea level, and the lighthouse has a height of 15 meters. There is a man fishing in a boat directly below Scottie who
has hooked a fish that is 10 meters below the surface of the water.
a. Use positive and negative numbers to represent the locations in relation to sea level.
Scottie =
Top of the lighthouse =
The boat =
The fish =
meters
b. How far is Scottie from the fish?
Answer:
30 m ;
15 m ;
0 m;
40 m
Step-by-step explanation:
Scottie's position = standing on cliff
Height of cliff = 30 m above sea level
Height of lighthouse = 15 meters
Position of fish = 10m below sea level
Above sea level = positive, +
Below sea level = negative, -
Scottie's position = 30 m
Top of lighthouse = 15m
BOAT = surface of sea = 0m
Fish = - 10 m
Distance of Scottie from fish :
Scottie's position - Position of fish
30m - (-10)m
30m + 10m
= 40m

Can someone plz help me!!!!
Answer:
The answer is 3.16
Answer:
8
Step-by-step explanation:
Use Pythagorean theorem a^2 + b^2= c^2.
6^2 + x^2 = 10^2 or 36 + x^2 = 100. Solve for x by subtracting 36 from both sides. X^2 = 64, then take the square root of both sides. X =8

Use the Law of Cosines to write an expression equivalent to a. I need this answer urgently pls!
9514 1404 393
Answer:
a = √(b² +c² -2bc·cos(A))
a = √(c² -b²)
Step-by-step explanation:
For sides a, b, c, and opposite angles A, B, C, the general form of the law of cosines is ...
a² = b² + c² -2bc·cos(A)
An expression for 'a' can be written by taking the square root.
a = √(b² +c² -2bc·cos(A))
__
If you recognize that cos(A) = b/c, then a substitution can be made:
a = √(b² +c² -2(bc)(b/c)) = √(b² +c² -2b²)
a = √(c² -b²) . . . . . . . same as the Pythagorean theorem

A motarcar is running at the rate of 66 km per hour. Each other its wheels makes 500 revolutios per minute. find the radius of the wheel.
Answer:
simple
Step-by-step explanation:
The radius of the wheel can be solved from its given speed and RPM.
Converting km/h to m/min
speed = 66 km / h = 66000 m / 60 min
speed = 1100 m / min
Converting one revolution to meters
1100 m / min = 500 revolution / min ... (given)
500 revolutions = 1100 m
1 revolution = 2.2 m
Solving for the radius of the wheels in meters
1 revolution = 2.2 m
2 * pi * radius = 2.2 m
radius = 2.2 m / 2 * pi
radius = 1.1 m / pi
radius = 0.3501 m

The measures of the three angles whose sum is 160 are in the extended ratio 2:5:9. Find the exact angle measures.
Answer: 20°, 50° and 90°
Step-by-step explanation:
From the question, we are informed that the measures of the three angles whose sum is 160 are in the extended ratio 2:5:9.
The exact angle measures will then be:
= 2/(2+5+9) × 160°
= 2/16 × 160°
= 20°
= 5/(2+5+9) × 160°
= 5/16 × 160°
= 50°
= 9/(2+5+9) × 160°
= 9/16 × 160°
= 90°

Answer:
7/12
Step-by-step explanation:
the least common denominator is 12
4 goes into 12 three times so you multiply both numbers in 3/4 by three
3/4 = 9/12
6 goes into 12 twice so multiply both the 1 and 6 by two
1/6 = 2/12
so the equation becomes 9/12 - 2/12
subtract the numerators

Step-by-step explanation:
The area of the shape in Step n is (n+1)²-2.
What is pattern?A recurring arrangement of numbers, forms, colours, and other elements constitutes a pattern in mathematics. The Pattern can be connected to any kind of occasion or thing. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern. Patterns can also occasionally be referred to as a series.
From the given pattern,
Area of the shape in step 1 is 2 square centimeter
Area of the shape in step 2 is 7 square centimeter
Area of the shape in step 3 is 14 square centimeter
Here, the pattern is 2²-2=2
3²-2=7
4²-2=14
so, the general form is (n+1)²-2
Therefore, the area of the shape in Step n is (n+1)²-2.

The measure of angle R is 3 degrees less than twice the measure of angle S. If the sum of the measures of the two angles is 72 degrees, find the measure of each angle.
Measures of the given angles:
∠S = 25° and ∠R = 47°
What is an angle?In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle.
There are two main parts related to an angle - the arms and the vertex.
Given,
Measure of angle R is 3 degrees less than twice the measure of angle S
⇒ 2∠S - ∠R = 3°
⇒ ∠R = 2∠S - 3° ------(a)
Sum of R and S
⇒ ∠R + ∠S = 72°
Substituting ∠R in terms of ∠S in above equation from equation (a)
2∠S - 3° + ∠S = 72°
3∠S - 3° = 72°
3∠S = 72° + 3°
3∠S = 75°
∠S = 75°/3
∠S = 25°
Substituting value of ∠S in equation (a)
∠R = 2 × 25° - 3°
∠R = 50° - 3°
∠R = 47°
Hence, ∠S = 25° and ∠R = 47° are the measures of given angles.

Consider U = {x|x is a negative real number}. Which is an empty set? {x|x ∈ U and x has a negative cube root} {x|x ∈ U and x has a negative square root} {x|x ∈ U and x is equal to the product of a positive number and –1} {x|x ∈ U and x is equal to the sum of one negative and one positive number}
Answer:
{x\ x e U and x has a negative square root} is an empty set.
Step-by-step explanation:
If x e U, x is a negative real number, and they don't have a square root (they don't have even roots). Their square roots are complex numbers, not real ones.
The set that will give an empty set will be {x|x ∈ U and x has a negative square root}
What is a set?A set is a collection of numbers or objects. They are not necessarily arranged in pattern.
Given the following sets
r U = {x|x is a negative real number}
We are to determine the set that is empty. This means we need the set of numbers that are not real numbers.
The square root of a negative number will give a complex number. Hence the set that will give an empty set will be {x|x ∈ U and x has a negative square root}

We want to find the graph of a system of inequalities. We want to select the correct option, but sadly is really hard to interpret the given text, so I will add a graph of the system at the end.
The system is:
y ≤ -3x + 1y ≤ (1/2)*x+ 3To graph these we first need to graph the two lines:
y =-3x + 1
Is a line with a negative slope that passes through the y-axis at y = 1.
Because here we have y ≤ -3x + 1 we know that y must be equal or smaller than the line, thus we need to shade below the line, and because y can be equal to any value in the line we need to use a solid line.
For the other equation:
y = (1/2)*x+ 3
We have a positive slope and this line intercepts the y-axis at y = 3.
Similar as before, here we have y ≤ (1/2)*x+ 3 so the shaded area will be below the line and the line must be solid.
With this in mind, we can graph the system, and you can see it below:

A linear function in slope intercept form is
y = mx + c
To find the equation, you need m and c. This can be found by substituting the points you have.
For example, 5 = -1(m) + c and -7 = 2(m) + c
From here, do simultaneous equations
c = m + 5
-7 = 2(m) + m + 5
3m = -7 -5
m = -4
c = m + 5
c = 1

HELP In △ABC, m∠A = 75° and m∠C = 20°, What is m∠B?
To solve this question, we must know the the angle sum property of a triangle. Therefore the value of ∠B is 85° when ∠A = 75° and ∠C=20° in △ABC
What is angle sum property of a triangle?According to angle sum property of a triangle, the sum of all angles of a triangle is always 180 degree. It can never be more than or less than 180 degree. If two angles of a triangle is given then the third angle can be calculated by subtracting the sum of two angle from 180°
The sum of the three angles in a triangle = 180° , that is
∠ A + ∠ B + ∠ C = 180°
Substituting the given values in the given equation we get
75° + ∠ B + 20° = 180°
∠ B + 95° = 180°
subtracting 95° from both sides we get
∠ B = 85°
Therefore the value of ∠B is 85° when ∠A = 75° and ∠C=20° in △ABC
