Amanda and Jeremiah are standing on the same side of a large lake. They are separated by a horizontal distance of 4000 ft. Both Amanda and Jeremiah can see a helicopter that is directly above the horizontal distance between them. Amanda’s angle of elevation to see the helicopter is 60 and Jeremiah’s angle of elevation to see it is 30. 1.What is the distance between Amanda and the helicopter?
Explanation: First of all we need to know if our triangle is a right triangle (has one 90° inner angle) to be able to use the law of sines to calculate the distance between Amanda and the helicopter.
Step 1: Once we know that the sum of all inner angles of a triangle is equal to 180° we can calculate the unknown angle as follows
As we can see above the missing inner angle is 90° which means it is a right triangle.
Step 2: Now we can use the law of sines as follows
once sin (90°) = 1 and sin (30°) = 0.5, let's calculate "x" below
[tex]\begin{gathered} \frac{x}{sin(30)}=\frac{4000}{sin90} \\ x=\frac{4000*0.5}{1} \\ x=2000ft \end{gathered}[/tex]Final answer: As we can see above, the final answer is 2000 ft

What are Fractions?
Fractions are referred to as the components of a whole in mathematics. A single thing or a collection of objects might be entire. When we cut a slice of cake in real life from the entire cake, the part represents the percent of the cake. The word "fraction" is derived from Latin. "Fractus" means "broken" in Latin. The fraction was expressed verbally in earlier times. It was afterward presented in numerical form.
A piece or sector of any quantity is another name for the fraction. It is indicated by the sign "/," such as a/b. For instance, in the fraction 2/4, the bottom part represents the denominator, and the top part the numerator. This article's focus is on going to learn the meaning of fractions in mathematics, different sorts of fractions, how to convert fractions to decimals, and a ton of problems that have been solved and well explained.

Solve the linear system using the elimination method. Type youranswer as an ordered pair in the form (#,#). 6x + 5y = -15-2x – 3y = 17
1) Solving that linear system using the elimination method, we'll proceed this way.
1.1 Choose one variable to be canceled out firstly. Let's choose the x variable:
6x + 5y = -15
-2x -3y= 17 Multiply this whole equation by 3
6x + 5y = -15
-6x -9y= 51 Add both equations
----------------------
0 -4y =36 Divide both sides by -4
y = -9
2) Now let's plug into any equation, usually the one with smaller numbers y= -9
-2x -3(-9) = 17
-2x +27 = 17 Subtract 17 from both sides
-2x =17-27
-2x = -10 Divide both sides by -2
x= 5
3) So the solution is (5, -9)

Ensure to write the equation withthe appropriate numbers plugged in.b. Maryse uses her equation to predict that she would travel 40 miles if she rode for four hours.Did she use her equation correctly? Explain why or why not.
ANSWER
1.) YES! Maryse used her equation correctly.
2.) NO! Maryse did not use her equation correctly.
EXPLANATION
Given:
A bike ride model: y = 7x
where:
1). x is the time Maryse spent riding,
2). y is the distance she traveled
Now, she rode 14 miles in the first two hours of her trip
That is:
y = 7x
where y = 14 miles and x = 2 hours
14 = 7(2)
14 = 14
She indeed used her equation correctly.
When she predicted that she would travel 40 miles if she rode for four hours.
That is:
y = 7x
where y = 40 miles and x = 4 hours
[tex]\begin{gathered} 40\text{ }\ne\text{ 7\lparen4\rparen} \\ 40\ne28 \end{gathered}[/tex]Hence, She indeed used her equation correctly in part one but she did not use her equation correctly in part two.

Let's start by completing the first table.
The questions gives the depth in two times:
- 2 hours after start -> 64 inches of water
- 4 hours after start -> 48 inches of water
From this, we can identifythe units:
- for time, we will use hours
- for depth, we will use inches
The first given values are:
- for time, 2
- for depth, 64
The second given valuesa are:
- for time, 4
- for depth, 48
So, the table is:
Quantity Name | Time | Depth of Pool
Unit | hour | inch
Given Value 1 | 2 | 64
Given Value 2 | 4 | 48
Now, we need to calculate the slope, which can be done using the given points and the equation:
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{48-64}{4-2} \\ m=\frac{-16}{2} \\ m=-8 \end{gathered}[/tex]So, the slope is -8 inches per hour.
The interceptwe the b in the equation:
[tex]y=mx+b[/tex]Where y is the depth and x is the time. So, using the first given values and the slope, we can find b:
[tex]\begin{gathered} 64=-8\cdot2+b \\ 64=-16+b \\ b=64+16 \\ b=80 \end{gathered}[/tex]Thus, the intercept is 80 inches.
So, the formula we have for the pump is:
[tex]y=-8x+80[/tex]Using it, we can answer questions 1 and 2:
1. After 6 hours means x = 6, so:
[tex]\begin{gathered} y=-8\cdot6+80 \\ y=-48+80 \\ y=32 \end{gathered}[/tex]So, y = 32, thus, the depth of the water will be 32 inches.
2. The level 24 inches mean y = 24, so:
[tex]\begin{gathered} 24=-8x+80 \\ 8x=80-24 \\ 8x=56 \\ x=\frac{56}{8} \\ x=7 \end{gathered}[/tex]Thus, x = 7, and the water will be at 24 inches after 7 hours.

20. A room is 24 feet long and 15 feet wide. How much will it cost to cover the floorwith carpet costing $36 a square yard if an extra 4 square yards must be purchasedfor matching?Answer
At first, we will change the feet to the yard because the cost of carpet is per square yard
Since 1 yard = 3 feet, then
Divide each dimension by 3 to change it from feet to yard
Since the length of the room = 24 feet, then
The length of the room = 24/3 = 8 yards
Since the width of the room = 15 feet, then
The width of the room = 15/3 = 5 yards
The rule of the area of the rectangle is
Area = Length x width, then
The area of the room = 8 x 5 = 40 square yards
Since we will add extra 4 square yards to it, then
The total area needs to cover = 40 + 4 = 44 square yards
Since the cost of 1 square yard = $36, then
Multiply the area by the cost to find the cost of the carpet
The total cost = 44 x 36 = 1584
The cost of the carpet is $1584

72b384 is a number in which one of its digits is 'b'. if the number is a multiple of 9, what is the numerical value of 'b'?
Answer:
3
Step-by-step explanation:
Hello!
A simple way to find if the number is a multiple of 9 is if the sum of the digits in the number is a multiple of 9, then the number itself is a multiple of 9.
So that means: 7 + 2 + b + 3 + 8 + 4 is a multiple of 9
If we add it up we should get: 24 + b
The multiples of 9 include 9,18,27,36,45,54....., and the closest multiple of 9 to 24 is 27. Therefore, the missing digit should be 3, as 27 - 24 is 3.
The next closest numbers would be 18 and 36, but you would need to add a negative number to get 18, and a two-digit number to get 36.

Decorations for the dance cost $120
the club is charging $10 per student that attends.
In the graph, the x axis is labelled with number of students and the y axis with amount of money collected
As they spend $120 for the decorations of the dance the starting point for the money raised is -120, upon charging 2 students the money they will get is 2 x 10 = 20
So the money raised will be
-120 + 20 = -100
The line will pass from point (0, -120) through (2, -100)
Therefore, graph with the x axis labeled number of students and the y axis labeled amount of money raised and a line going from the point 0 comma negative 120 through the point 2 comma negative 100 is correct.
