Emma and Ed walk into a room containing 30 assembled Tworks and enough pieces to assemble 100 more Tworks. A Twork takes eight minutes to assemble and 10 minutes to disassemble. If Emma starts assembling Tworks as Ed begins disassembling the ones that were already made, and they both continue to work until there are exactly 35 assembled Tworks in the room (and no partially assembled or disassembled Tworks), how many minutes will Emma have worked?
Answers
Answer:
Start with 30 assembled, parts for 100 more.
Each minute results in +1/8 and -1/10
So we want
30 + x/8 - x/10 = 35
x/8 - x/10 = 5
5x - 4x = 200
x = 200 minutes
During 200 minutes, 25 are assembled, 20 are disassembled,
resulting in a net gain of 5, added to the original 30.
Bike ride:
Total distance: 40 km
Desired average speed 20 km/hr
Total time will be 2 hours
20 km at 15 km / hr = 4/3 hour taken
Leaves 2/3 hour for 20 km
20 km in 2/3 hour = 30 km/hr
Gas mileage:
Let m = city mileage
m + 3 = highway mileage
136 / (m+3) + 155 / m = 9
9m^2 - 264m - 465 = 0
m = 31 (discarding negative value)
Bricklaying:
Let b = number of bricks in wall
Lisa lays b/9 bricks per hour
Lauren lays b/10 bricks per hour
b = 5 * (b/9 + b/10 - 10)
b = 5b/9 + 5b/10 - 50
90b = 50b + 45b - 4500
b = 900
Lisa does 100 per hour
Lauren does 90 per hour
Together they do 180 per hour.

Step-by-step explanation:
Emma will have worked for 200 minutes.
Given, there are 30 assembled T works in the room initially.
A T work takes eight minutes to assemble, so the rate of assembling T work in one minute will be [tex]\frac{1}{8}[/tex].
Similarly, a T work takes 10 minutes to disassemble. so the rate of disassemble of T work will be [tex]\frac{1}{10}[/tex].
Let Emma worked for x min.
According to the question, Emma starts assembling T works as Ed begins disassembling the ones that were already made and they both continue to work until there are exactly 35 assembled T works in the room. So we can write it in equation for form as,
[tex]30+\frac{x}{8} -\frac{x}{10} =35[/tex]
[tex]\frac{x}{8} -\frac{x}{10}=5\\[/tex]
[tex]\frac{5x-4x}{40} =5[/tex]
[tex]x=5\times40[/tex]
[tex]x=200[/tex]
Hence Emma have to work for 200 minutes.

Jacinta says that the product of a rational number and an irrational number is always irrational. Explain her error.
Answers
Jacinta says that the product of a rational number and an irrational number is always irrational her claim is wrong.
What is a rational number?A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.
Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.
Given that Jacinta says that the product of a rational number and an irrational number is always irrational.
Her statement is incorrect because if 0 a rational number is multiplied with the π which is irrational then the result will be 0 which is rational.
Therefore, Jacinta's claim is wrong.

Answers
Answer:
C
Step-by-step explanation:
To do this, let's let the decimal equal n. Thus:
[tex]2.\bar1=n[/tex]
There is only one digit repeating, so let's multiply both sides of the equation by 10:
[tex]21.\bar1=10n[/tex]
Now, subtract n from both sides:
[tex]21.\bar1-n=10n-n[/tex]
On the right, it becomes 9n. However, the left, however, expand, the decimal. In other words:
[tex]21.1111...-2.1111...=9n[/tex]
All of the repeating 1s will cancel out. Thus:
[tex]21-2=9n[/tex]
Subtract:
[tex]19=9n[/tex]
Divide both sides by 9:
[tex]n=\frac{19}{9}[/tex]
And since we set the decimal equal to n originally...
[tex]2.\bar1=\frac{19}{9}[/tex]
And we're done!
Notes:
This is the algebraic way to write a repeating decimal into a fraction. You can, of course, always just use a calculator and guess and check.

This makes squares the numerator and circles the denominator. After you set it into a fraction just reduce the fraction to its simplest form.
