Answer:
Science Club- y=10x+20
Math Club- y=5x+50
They will be equal 6 weeks
Step-by-step explanation:
X equals the number of weeks that have passed. In example of the science club, they would gain $10 every week, making the equation y (total money) equal to 10 dollars a week (or 10x.)
Since we know they begin with 20 dollars, we'll simply add that to the 10 dollars a week.
To find the week when they will be equal, we have to put both equations equal to each other.
10x+20=5x+50
Now we solve for x, or the number of weeks when the equations (and values) will be equal.
10x+20=5x+50
5x+20=50
5x=30
x=6
So... 6 weeks :)

what is equavilent to (10x+7r-r^(2))+(-6r^(2)-18+5r)
Answer:
−7r^(2)+12r+10x−18
Step-by-step explanation:
Grab the original equation: 10x+7r−r^(2)−6r^(2)−18+5r
For subtraction bits, treat them as negatives: 10x+7r+−r^(2)+−6r^(2)+−18+5r
Combine like terms: (−r^2+−6r^2)+(7r+5r)+(10x)+(−18)
Simplify that, and you get your final answer: −7r^(2)+12r+10x+−18
A2. Find y' and y" for y^2 = x^2
+ sinxy
Answer:
y' = (2x + y cosxy)/(2y + x cosxy)
Step-by-step explanation:
Using implicit differentiation:
y^2 = x^2 + sin xy
2y y' = 2x + cos xy * (xy' + y)
2y y' = 2x + xy' cos xy + y cos xy
2y y' - xy' cosxy = 2x + ycos xy
y' = (2x + y cosxy)/(2y - x cosxy)
20 POINTS PEOPLE!!!
it was estimated that 200 people would attend game night, but 196 people actually attended what is the percent error, to the nearest percent, of the estimate?
Subtract the two numbers to find the difference:
200-196 =4
Divide the difference by the estimated number:
4/200 = 0.02
Multiply by 100 to change to percent:
0.02 x 100 = 2%
The answer is 2%

2(6 + 3n) - 4
i need the answer...
.....
Answer:
See below.
Step-by-step explanation:
2(6 + 3n) - 4 (Given)
12 + 6n - 4 (Distribute)
6n + 8 (Add like terms)
3n + 4 (Divide by a factor of 2)
In case you wanted to solve for n:
2(6 + 3n) - 4 = 0 (Given)
12 + 6n - 4 = 0 (Distribute)
6n + 8 = 0 (Add like terms)
6n = -8 (Substract on both sides)
n = -4/3 (Divide 6 on both sides)

Which graph shows the solution to the system of linear inequalities? x+5y>=5. y<=2x+4
Answer:
The correct answer is B.
Step-by-step explanation:
The solution to the inequalities is (-11/15. 38/15)
Equation of a lineGiven the systen of inequalities expressed as:
x+5y>=5y<=2x+4inequality graphIn order to get the graph that shows the solution and the coordinate of the solution, equate the inequalities to havee:
(5-x)/5 = 2x + 4
5 - x = 10x + 20
20 - 5 = -11x
15 = -11x
x = -11/15
Given that y = 2x + 4
y = -22/15 + 4
y = 38/15
The solution to the inequalities is (-11/15. 38/15)

5.412 * 105
5.388 * 102
5.388 * 103
5.388 * 105
Answer:
[tex]5.4*10^{5}-1.2*10^{3}=5.388*10^{5}[/tex]
Step-by-step explanation:
We can rewrite [tex]1.2*10^{3}[/tex] as [tex]0.012*10^{5}[/tex].
Now, let's subtract each term:
[tex]5.4*10^{5}-0.012*10^{5}[/tex]
we can take a common factor.
[tex](5.4-0.012)*10^{5}=5.388*10^{5}[/tex]
Therefore the answer is [tex]5.388*10^{5}[/tex].

A local theater charges $8 for adult tickets and $6 for children's tickets to a play. If a group of 24
goes to the theater and pays $164, how many of each ticket type did the group purchase?
Answer:
The theater was attended by 10 adults and 14 children.
Step-by-step explanation:
As the theater charges adults $ 8 and children $ 6 for each ticket, there is a surcharge of $ 2 for each adult. Thus, given that a group of 24 people attended the theater, as a minimum (that is, if they were all children) the establishment should charge $ 144 (6 x 24). Now, since it charges $ 164, there is a difference of $ 20 (164 - 144), attributable to the surcharge paid by adults for each ticket. Thus, since this surcharge is $ 2, dividing 20 by 2 we obtain 10, which is the number of adults who attended the theater.
This is verified by the following calculation:
10 x 8 = 80
14 x 6 = 84
80 + 84 = 164
Therefore, the theater was attended by 10 adults and 14 children.

Answer:
53 remainder 23
= 53 23/38
Step-by-step explanation:
Answer:
52 with 9 remaining
Step-by-step explanation:
When dividing this, we find that our whole number we are going to multiply with is 52, and if it was 53 it would be over 2,037. So, we multiply 39 by 52 and get 2,028, which is an extra of 9 remaining.

How many employees accumulated less than 3,000 miles?b. Convert the frequency distribution to a cumulative frequency distribution.c. Portray the cumulative distribution in the form of a cumulative frequency polygon.d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?
Answer:
a. How many employees accumulated less than 3,000 miles?
The number of employees accumulated less than 3,000 miles= 5
So the number of employees accumulated less than 3,000 miles is 5.
d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?
8.5 thousands of miles, found by starting at 75 percent on the vertical axis on the right, over to the polygon and then down to the horizontal axis.
Step-by-step explanation:
The given frequency distribution representing the number of frequent flier miles accumulated by the employees in a company.
Frequent Flier Miles (000) Frequency
0 up to 3 5
3 up to 6 12
6 up to 9 23
9 up to 12 8
12 up to 15 2
Total 50
a. How many employees accumulated less than 3,000 miles?
The number of employees accumulated less than 3,000 miles= 5
So the number of employees accumulated less than 3,000 miles is 5.
b. Convert the frequency distribution to a cumulative frequency distribution.
We make the cumulative frequency distribution from the frequency distribution by adding up a frequency and all other frequencies below it.
Frequent Flier Miles Frequency Cumulative frequency
0 up to 3 5 5
3 up to 6 12 17
6 up to 9 23 40
9 up to 12 8 48
12 up to 15 2 50
Total 50
d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?
8.5 thousands of miles, found by starting at 75 percent on the vertical axis on the right, over to the polygon and then down to the horizontal axis.
