Mike and Lilly are working together on a science project. They agreed to
meet halfway between their houses and ride their bikes to the library
together. Approximately how far will Mike and Lilly ride to the library once
they meet each other at the halfway point?
Answers
The approximate distance Mike and Lilly will have to travel between halfway point and Library is 7.8 miles.
From the graph :
Mike's coordinate = (-4, 2) Lilly's coordinate = (2, - 2) Library coordinate = (4, 6)Meeting point = Halfway point :
(x1 + x2) /2 ; (y1 + y2) / 2
X - coordinate = (-4 + 2) / 2 = - 2/ 2 = - 1
Y - coordinate = (2 + (-2)) /2 = 0/2 = 0
Hence, meeting point = (-1, 0)
The distance between meeting point and library :
Distance = √[(x2 - x1)² + (y2 - y1)²]
Distance = √[(4 - (-1))² + (6 - 0)²]
Distance = √(25 + 36)
Distance = √61 = 7.8 miles
Therefore, the distance between halfway point and library ls approximately 7.8 miles

find the length of the hypotenuse of the right triangle. leave your answer in simplest radical form. not drawn to scale.
Answers
1) Notice that this is a 45-45-90 triangle, meaning the ratio of sides and hypotenuse is 1:1:sqrt(2)
Since the legs are 4, that would mean the hypotenuse would be 4*sqrt(2)
2) Pythagorean theorem: a^2 + b^2 = c^2
4^2 + 4^2 = 32

Answers
Answer:
x = 32
Step-by-step explanation:
The angle above 72° is 108° because they are supplementary angles, meaning they add up to 180°. Then we can set the equation 108° = (3x + 12)° because they are alternate interior angles, meaning that they are the same. So then we just solve for x.
108 = (3x + 12)
108 - 12 = 3x
96 = 3x
96 / 3 = x
32 = x
A student wrote a photography manual which she plans to sell online for $ 13 per copy. Her total expenses were $ 55. Write a linear equation to show the relationship between x , the number of manuals the student sells, and y , the profit the student earns.
Answers
Answer:
y = 13x - 55
Step-by-step explanation:
So this is what we know
Selling price = $13 per copy
Expenses = $55
The formula for profit in this case is:
Profit = total selling price - expenses
In which y is the profit
The total selling price is 13x. x here is for the number of manuals she sells
The expenses are $55.
This then becomes y =13x - 55

The required magnitude of the constant of the proportionality is 8.25.
Given that,
The cost of a birthday party at a skating rink is proportional to the number of guests. The skating rink charges $82.50 for 10 guests.
proportionality is defined as between two or more sets of values, and how these values are related to each other in a sense are they directly proportional or inversely proportional to each other.
Here,
Let the number of the guest be x and the total charge for the party be y,
y = kx
Where K is the constant of proportionality,
Substitute the values in the equation for the number of guests and corresponding charges,
82.50= K(10)
K = 8.25
Thus, the required magnitude of the constant of the proportionality is 8.25.

One week, Sharon worked 18 hours as a lifeguard and 12 hours at a concession stand and earned $228. The next week, she earned $254 for 24 hours as a lifeguard and 8 hours at the concession stand. How much per hour does she get paid for each job?
Answers
Answer:
She is paid $6.25.hour at the concession and $8.50 as a lifeguard.
Step-by-step explanation:
We know:
18 hours as a lifeguard
12 hours at concession
Total earned = $228
18L + 12C = 228
Then:
24 hours as a lifeguard
8 hours at concession
Total earned = $254
24L + 8C = 254
Move one equation around to get one variable by itself: in this case we can solve for L:
18L + 12C = 228
18L = 228 - 12C
L = (228/18) - (12/18)C
Plug in for L:
24((228/18) - (12/18)C) + 8C = 254
Solve for C:
C = 6.25
Now that we know C, plug in value for C and solve for L:
18L + 12(6.25) = 228
L = 8.5
So she is paid $6.25.hour at the concession and $8.50 as a lifeguard.

To solve for the slope, choose two pairs of coordinates and substitute their values into the slope formula.
Let (x1, y1) = (1, 5)
(x2, y2) = (2, 4)
m = (y2 - y1)/(x2 - x1)
m = (4 - 5)/(2 - 1)
m = -1/1
m = - 1
Therefore, the slope, m = -1.
For the y-intercept, choose one of the given points, and use it along with the slope to solve for the y-intercept. Using point (2, 4) and the slope, m = -1, substitute their values into the slope-intercept form:
y = mx + b
4 = -1(2) + b
4 = -2 + b
Add 2 to both sides to solve for b:
4 + 2 = -2 + 2 + b
6 = b
Therefore, the linear equation is :
y = -x + 6

The correct answer is 20.0% increase.
Step-by-step explanation:
In this situation, you would need to find how to find the percentage of change.
Therefore, you will need to first use subtraction, division and then multiplication to justify your answer.

A landfill has 30,000 tons of waste in it. Each month it accumulates an average of 585 more tons of waste. Let m represent the number of months.
What is a function that represents the total amount of waste after m months?
Answers
Answer:
f(m) = 585m + 30, 000
Step-by-step explanation:
First you need to set up your variable which is m which makes f(m) and since each month gives 585 tons per month we have the variable attached to that (585m). However, we already start with 30,000 so we add that in. You can check the answer by replacing m with a number, which for me I will choose 10, which gives me 35,850 which makes sense.
