Answer:
d₃ = 803.9 Miles
Step-by-step explanation:
d₁ = 560 Miles
R₁ = N35⁰E
d₂ = 410 Miles
R₂ = S76⁰E
d₃ = ?
α = 35⁰+76⁰ = 111⁰
We can apply the Law of Cosines as follows
d₃ = √(d₁² + d₂² - 2*d₁*d₂* Cos α)
⇒ d₃ = √(560² + 410² - 2*560*410* Cos 111⁰) = 803.9 Miles

Amy spent $6.00 for 2 gallons of gas. Bobby paid $15.00 for 6 gallons of gas. Carlos paid $32.00 for 8 gallons of gas. List the people in order of how much they paid for one gallon of gas, from the cheapest to the most expensive cost per gallon. Amy, Carlos, Bobby Amy, Bobby, Carlos Bobby, Amy, Carlos Bobby, Carlos, Amy
Answer: Bobby, Amy, Carlos
Step-by-step explanation:
Amy spent $6.00 for 2 gallons of gas.
The price per gallon will be:
= $6/2
= $3 per gallon
Bobby paid $15.00 for 6 gallons of gas.
The price per gallon will be:
= $15/6
= $2.5 per gallon
Carlos paid $32.00 for 8 gallons of gas.
The price per gallon will be:
= $32/8
= $4 per gallon
From the cheapest to the most expensive will be:

A firefighter truck can hold 3000 gallons of water. A firefighter can deliver 160 gallons of water every 2 minutes.
1. How much water will be delivered in 10 minutes?
2. How long will it take for the firefighter to empty the tank?
Answer:
Step-by-step explanation:
1. solution
160 gallons = 2 min
160 x 5 = 2 x 5
800 gallons = 10 min
2. solution
160 x 19 = 2 x 19
2880 = 36
So
approximately 38 min

A charity organization had a fundraiser where each ticket was sold for a fixed price. After selling 200 tickets, they had a net profit of $12,000.
They had to sell a few tickets just to cover necessary production costs of $1,200.
Let y represent the net profit (in dollars) when they have sold x tickets.
Which of the following could be the graph of the relationship?
Answer:
Step-by-step explanation:
y = 66x - 1200
The charity organisation has to sell a number of tickets to cover their production costs of $1,200. It is given that after selling 200 tickets they retain a net profit of $12,000. Net profit is deduced as: Total sales - total costs. Sales is calculated as total tickets x selling price per ticket.
If we let b represent the sales earned from selling tickets, then:
Net profit = total sales - total costs
12,000 = 200b - 1,200
We can then solve for b by taking the 1200 to the other side of the equal sign. When we do that the sign of that number changes. This is also the same as adding 1200 to both sides of the equal sign:
∴12000 + 1200 = 200b
13200 = 200b
To get the price of one single ticket, b, we need to divide both sides by 200.
∴ b = 66
This means that each ticket's selling price is $66.
So when when we take it back to the calculation of net profit then it becomes:
Net profit = total sales - total costs
y = 66x - 1200
To test:
y = 66x - 1200
= 66 (200 tickets) - 1200
= $12,000

Zelda and Ricky are laying floor tiles for a 15 ft by 18 ft room using a scale drawing. Their drawing is 9 in. by 10.8 in. Zelda thinks the scale for the drawing is 1 to 5/3. Ricky thinks it is 1 to 20. Can they both be right? Explain why or why not?
ANSWER QUICKLY 10 min Please Will Brainliest
Answer:
No, they cannot both be right
Step-by-step explanation:
Firstly, we need to convert the ft in the real room to inches
Mathematically; 1 foot = 12 inches
So 15 ft will be 15 * 12 = 180 inches
18 ft will be 18 * 12 = 216 inches
Now let’s look at their drawings;
9 to 10.8
So 9 translated to 180 while 10.8 translated to 216
So the ratios here are;
9/180 and 10.8/216 = 1 : 20 for the ratio of the drawing to the real measure
This shows that only Ricky is right

a random group of high school and college students were asked if they study with or without listening to music. the frequency table below shows the results of the poll. a 4-column table with 3 rows. the first column has no label with entries high school, college, total. the second column is labeled music with entries 68, 85, 153. the third column is labeled no music with entries 65, 51, 116. the fourth column is labeled total with entries 133, 136, 269. which statements are true? check all that apply. the table shows conditional relative frequencies by column. the table shows conditional relative frequencies by row. the conditional relative frequency that someone is in high school, given that the person prefers to study without music, is about 0.56. if someone prefers to study with music, the probability the person is in college is about 63%. if someone prefers to study with music, the probability the person is in hs is about 44%.
Answer:
The conditional relative frequency that someone is in high school, given that the person prefers to study without music, is about 0.56.
If someone prefers to study music, the probability the person is in HS is about 44%.
Step-by-step explanation:
In the music column, we see that
total people who prefer to study with music = 153
high school students = 68
So, probability of high school students who study with music
= 68/153
= 0.44
= 44%.
College students = 85
Probability of college students who prefer to study with music
= 85/153
= 0.56
= 56%.
So, the correct statements are :
The conditional relative frequency that someone is in high school, given that the person prefers to study without music, is about 0.56.
If someone prefers to study with music, the probability the person is in HS is about 44%.

61 miles. Write and solve an equation to find the number of days Claire traveled. Explain each step
of your problem solving strategy.
Gm
d = 5
What was the total number of days that Claire traveled?
Claire drove for days in all
(Type a whole number.)
Answer:
Claire traveled for 9 days.
Step-by-step explanation:
Given:
Total Distance traveled = 701 miles
Distance traveled each day = 80 miles
Distance traveled on last day = 61 miles
We need to find the number of days Claire traveled.
Solution:
Let the number of days Claire traveled be denoted by 'd'.
Now we can say that;
Total Distance traveled is equal to sum of Distance traveled each day multiplied by number of days and Distance traveled on last day.
framing in equation form we get;
Now Subtracting both side by 61 using Subtraction Property of Equality we get;
Now Dividing both side by 80 we get;
Hence Claire traveled 80 miles in 8 days and 61 miles on last day making of total 9 days of travel.

Intersection points will be those points that belong to both lines.
We have the lines Line FG and Line GF.
Line FG: This is the line that connects the point F and the point G.
Line GF: this is the line that connects the point G and the point F.
Now, by unicity, we know that there is only one line that connects two points, then Line FG and Line GF must be the same line.
Then, because both lines are the same line, we can say that "All the points in Line GF are in the Line FG"

EQUATION:
(10 + 10 + 13 + 14 + 16 + 19 + 23) / 7
10 + 10 + 13 + 14 + 16 + 19 + 23

3. The equation 4x + 16y = 36 is a true equation for a particular
value of x. Explain why x + 4y = 9 is also true for the same value of x.
Answer:
See below.
Step-by-step explanation:
We know that the equation [tex]4x+16y=36[/tex] is a true equation for a particular value of x.
Now, let's see what happens if we divide everything by 4. In other words:
[tex]\frac{4x+16}{4}=\frac{36}{4}[/tex]
Divide:
[tex]x+4=9[/tex]
So, we get [tex]x+4=9[/tex].
When we divided everything by 4, we used the division property of equality. Under this property, the equation remains the same even if we divided since we did the same thing to both sides of the equation.
Therefore, [tex]x+4y=9[/tex] is also true for the same value of x because it is just a simplified version of [tex]4x+16y=36[/tex].

What are the domain and range of f (x) = log (x 6) minus 4?
Answer:
We will see that the domain of the function is:
D: {x | x ∈ R | x > -6}
How to find the domain of a function?
To find the domain of a function, we start by assuming that it is the set of all real numbers, and then we remove the problematic points.
In this case, we have a logarithm, and as you may remember, we can only evaluate the logarithm in positive values, so we need to remove all the values of x such that:
x + 6 ≤ 0
Solving for x, we get:
x ≤ -6
So the only values of x allowed are the ones that make the next inequality true:
x > -6.
Thus we can write the domain as:
D {x | x ∈ R | x > -6}
Where the second part, x ∈ R, is usually ignored, as we assume that x is a real number unless we specify that it is not, but just for completion, I wrote it.
