-Show Schedule-
Chemistry-Every 10 minutes
Electricity-Every 20 minutes
Recycling-Every 6 minutes
Fossils-Every 45 minutes
The first showing for all shows is at 10:00 A.M.
Answers
Chemistry: 10:00 10:10 10:20 10:30
Recycling: 10:00 10:06 10:12 10:18 10:24 10:30
As you can see both Chemistry and Recycling both have a LCM of 10:30 which tells us that the time for which both Chemistry and Recycling start at the same time during the show is 10:30AM.
Final answer:
The chemistry and recycling presentations coincide every 30 minutes starting from 10:00 A.M. They will occur at the same time at 10:30 A.M., 11:00 A.M., 11:30 A.M., etc., until 5:00 P.M.
Explanation:
To solve this problem, we need to find the common multiple of 10 and 6, which is the frequency in minutes of the chemistry and recycling presentations respectively. The least common multiple (LCM) of 10 and 6 is 30. So, the chemistry and recycling presentations will coincide every 30 minutes.
Starting at 10:00 A.M., they would coincide at 10:30 A.M., 11:00 A.M., 11:30 A.M., and continue in this pattern until 5:00 P.M.

I can help you with graphing quadratics in intercept form. Here's a step-by-step guide:
Step 1: Identify the intercepts
The intercepts are the points where the parabola crosses the x-axis and y-axis. In intercept form, the x-intercepts are given by the factors of the quadratic expression. For example, in the equation f(x) = 2(x+4)(x+6), the x-intercepts are -4 and -6. To find the y-intercept, set x = 0 and solve for y.
Step 2: Find the vertex
The vertex is the point where the parabola reaches its maximum or minimum value. The x-coordinate of the vertex is the average of the x-intercepts. In the equation f(x) = 2(x+4)(x+6), the x-intercepts are -4 and -6, so the x-coordinate of the vertex is (-4 + -6)/2 = -5. To find the y-coordinate of the vertex, substitute the x-coordinate into the equation and solve for y.
Step 3: Plot the intercepts and vertex
Mark the intercepts and vertex on the coordinate plane.
Step 4: Sketch the parabola
Draw a smooth curve that passes through the intercepts and vertex. The parabola should be symmetric about the vertical line passing through the vertex.
Example:
Let's graph the equation f(x) = 2(x+4)(x+6).
Step 1: Identify the intercepts
The x-intercepts are -4 and -6. To find the y-intercept, set x = 0 and solve for y:
f(0) = 2(0+4)(0+6) = 48
So the y-intercept is (0, 48).
Step 2: Find the vertex
The x-coordinate of the vertex is (-4 + -6)/2 = -5. To find the y-coordinate of the vertex, substitute x = -5 into the equation:
f(-5) = 2(-5+4)(-5+6) = 2
So the vertex is (-5, 2).
Step 3: Plot the intercepts and vertex
Plot the intercepts (-4, 0), (-6, 0), and (0, 48), and the vertex (-5, 2) on the coordinate plane.
Step 4: Sketch the parabola
Draw a smooth curve that passes through the intercepts and vertex. The parabola should be symmetric about the vertical line passing through the vertex.
The graph of the equation f(x) = 2(x+4)(x+6) is a parabola that opens upwards and has intercepts at (-4, 0), (-6, 0), and (0, 48). The vertex of the parabola is at (-5, 2).

Let x represent the months, and y for the amount of money.
For Carissa: For Louann:
x = y x = y
-- -- -- --
0 $250 0 $1230
1 $330 1 $1170
2 $410 2 $1110
3 $490 3 $1050
4 $570 4 $990
5 $650 5 $930
6 $730 6 $870
7 $810 7 $810
You could also do the equation:
80x + 250 = -60x + 1250
where you will get x=7.
Then substitute 7 to the x's in the equation which will give you $810 for each.
The answer is: It will take 7 months. Then, they will both have $810 in their accounts.
This exercise is trying to get you to write an equation
that describes what's going on.
Carissa has $250 today, and she adds $80 to it each month.
In 'm' months from now, she'll have 80m more than $250.
C (for Carissa) = 250 + 80m
Louann has $1230 today, and she takes out $60 each month.
In 'm' months from now, she'll have 60m less than $1230.
L (for Louann) = 1230 - 60m
Carissa has less money today, but it's growing $80 every month.
Louann has more money today, but it's losing $60 every month.
Eventually, they'll both have the same amount.
The question is: When and how much ?
Well, when they both have the same amount, then C = L .
250 + 80m = 1230 - 60m
That's the end of the hard part of this problem ... writing
the equation. The rest is easy, and I'm sure you'd have
no trouble solving it. But since I'm on a roll, and I'm
going to take your 5 points, I might as well keep going:
250 + 80m = 1230 - 60m
Subtract 250 from each side: 80m = 980 - 60m
Add 60m to each side: 140m = 980
Divide each side by 140 : m = 7
This is telling us that after 7 months, Carissa and Louann will both
have the same amount of money in their accounts.
The problem also asks us how much that is. So let's find the
amount for both of them, just to check our work and make sure
they're both the same:
Carissa: 250 today + (7 months x $80/month) = 250+560 = $810 .
Louann: 1230 today - (7 months x $60/month) = 1230-420 = $810
yay !
