Answer:
500, or 400 if its 4
Step-by-step explanation:
Answer:
1) x = 0, x = 1
2) x = -0.387 , x = 1.721
Step-by-step explanation:
3x² - 3x + 2 = 2
To convert this into the given graph, subtract 3 from both sides, you get
3x² - 3x - 1 = -1
You can find the x values for y = -1 to solve the given equation.
At y = -1, x = 0, 1
3x² - 3x - 1 = x + 1
To solve for this, add a straight line y = x + 1 on the same graph and look for the point of intersections
You'll see the line and the graph meet at two points:
x = -0.387 and x = 1.721
Find multiples of 30 and 40:
30: 30, 60, 90, 120, 150
40: 40, 80, 120, 160
The least common multiple is 120, so every 120 minutes they willl both ring.
1 hour = 60 minutes:
120/60 = 2 hours.
The bells ring together every 2 hours.
8 + 2 = 10 am
10 + = 12pm
12 + 2 = 2 pm
The bells will ring together at am, 12 pm and 2 pm.
Answer and Step-by-step explanation:
It be more than 2 ounces and less than 1.5 ounces
The amount of plastic that is melted in 5.7 minutes is 1.71
To find this, you would use the point on the graph. Divide both of those numbers by 4.
(4, 1.2)
4/4 = 1.
1.2/4 = 0.3.
So, for every minute, 0.3 of an ounce of plastic is melted.
We then multiply 0.3 by 5.7 to get 1.71.

These problems are what is known as changing a mixed fraction to an improper fraction. Lets start with 5 1/8.
What we want to do is take the big number on the side and add it to the top of the fraction in a special way to make it an improper fraction. (An improper fraction means a fraction with a bigger top than bottom).
To add 5 to 1/8, we have to multiply 5 by 8 and then add it. 5 times 8 is 40 so if we add that to the top we know that the improper fraction we are looking for is 41/8.
We can do the same thing for 3 4/12, multiply 3 by 12 and add it to the top of the fraction. 3 times 12 is 36, add that to the top to get 40/12.
See if you can do 1 6/12 and comment with an answer, if you get it wrong I will keep helping you till we get this down!
