Answer:
The following points are on the line
(x,y) = (2,120)(x,y) = (3,180)(x,y) = (4,240)There are other points on the line, but I'm focusing on the points where the three filled in circles are shown. I'm ignoring (0,0) because that point won't be useful for the next section below.
Pick any of the three points and divide y over x
y/x = 120/2 = 60y/x = 180/3 = 60y/x = 240/3 = 60Whatever point you choose, you'll get the same ratio. The constant of proportionality is 60.
In the context of this problem, the 60 refers to the speed of the car.
The car travels 60 miles in 1 hour, or at a speed of 60 mph.

Alex and Carmen both sell items at craft fairs. Alex earns $36 for 3 birdhouses, and Carmen earns $75 for 5 scarves. What is the unit rate that each person earns for their craft? How many birdhouses will Alex need to sell in order to make as much as Carmen does when she sells 12 scarves? How do you know?
Answers
Answer:
To be able to find the unit rate that each person earns for their craft, you have to divide the amount each person earns by the number of units:
Alex: $36/3=$12 per unit
Carmen: $75/5=$15 per unit
To find the amount of birdhouses that Alex will need to sell in order to make as much as Carmen does when she sells 12 scarves, first you have to determine the amount that Carmen earns when she sells 12 scarves:
$15*12=$180
Now, you need to divide $180 by the price per unit Alex earns to find the amount of birdhouses that he needs to sell:
$180/$12=15
This means that Alex needs to sell 15 birdhouses to make as much as Carmen does when she sells 12 scarves
A restaurant earns $10 for each hour worked up to 40 hours each week and 15 for each additional hour worked over 40 hours. If x represents the total number of hours the restaurant host work,which function,f(x), represent the total amount the restaurant host would earn if working for more than 40 hours
Answers
Answer:
[tex]f(x) = 15x - 200[/tex]
Step-by-step explanation:
Given
[tex]Earnings = \$10[/tex] per hour for 40 hours, weekly
[tex]Additional\ Hour = \$15[/tex] per hour over 40 hours, weekly
Required
Determine f(x)
From the question, we have that
x represents hours worked
Earnings in 40 hours is: 40 * 10 = $400
Hours over 40 will be: x - 40
So, earnings during this time will be: (x - 40) * 15
Total earnings is:
[tex]f(x) = 400 + (x - 40) * 15[/tex]
[tex]f(x) = 400 + 15x - 600[/tex]
[tex]f(x) = 15x - 600 + 400[/tex]
[tex]f(x) = 15x - 200[/tex]

A hockey player strikes a hockey puck. The height of the puck increases until it reaches and maximum height of 3 feet, 55 feet away from the player. The height y (in feet) of a second hockey puck is modeled by y=x(0.15-0.001x), where x is the horizontal distance (in feet). Compare the distances traveled by the hockey pucks before hitting the ground.
Answers
Answer:
Distance traveled by hockey puck of second player is 40 feet more than that of first player.
Step-by-step explanation:
Maximum height of 3 feet is attained by the hockey puck of first player is when the puck is 55 feet away from the player.
It is at the mid point of the total horizontal distance to be traveled by the hockey puck.
So, the horizontal distance traveled by hockey puck of first player = 55 + 55 = 110 feet
Second player:
[tex]y=x(0.15-0.001x)[/tex]
where [tex]y[/tex] is the height of a second hockey puck
[tex]x[/tex] is the horizontal distance.
When the puck hits the ground, [tex]y=0[/tex]
Now, let us find the value of [tex]x[/tex].
[tex]\Rightarrow 0=x(0.15-0.001x)[/tex]
At [tex]x=0[/tex] feet or [tex]x=150[/tex] feet, [tex]y=0[/tex]
Therefore, the distance traveled by second hockey puck is 150 feet.
So, the answer is:
Distance traveled by hockey puck of second player is 40 feet more than that of first player.

y = 15∠abc = 68°∠bac = 78°∠acb = 34°Step-by-step explanation:
It is helpful to realize that the exterior angle is equal to the sum of the remote interior angles:
146° = (5y+3)° +(4y+8)°
135 = 9y . . . . . . . . . . . . . . divide by °, subtract 11
15 = y . . . . . . . . . divide by 9
∠abc = (4y+8)° = (4·15 +8)° = 68°
∠bac = (5y+3)° = (5·15 +3)° = 78°
∠acb = 180° -146° = 34°
