The value of y varies inversely as the cube of x and y=1 when x=6. Find the value of y when x =2.
Answer:
y=27 when x=2
Step-by-step explanation:
y varies inversely as the cube of x
y=k(1/X^3)
y=1 when x=6
y=k(1/X^3)
1=k(1/6^3)
1=k(1/216)
k=1÷1/216
K=1×216/1
k=216
find y when x=2
y=k(1/X^3)
y=216(1/2^3)
y=216(1/8)
y=216/8
y=27
Dr. Khan is combining a 20% acetic acid solution with a 60% acetic acid solution. She wants to obtain 10 liters of a 40% acetic acid solution, how many liters of the 20% acetic acid solution does Dr. Khan need to create the 40% acetic acid solution?
Answer:
Dr Khan will add 5 liters of 20% acetic acid solution.
Step-by-step explanation:
Dr Khan is combining two solutions of acetic acid with the given concentrations of 20% and 60% respectively.
Let the amount of 20% acetic acid, he added to get 10 liters of 40% solution = 'a' liters
Volume of 60% solution used will be = (10 - a) liters
Now the equation will be,
Amount of solution (1) × 20% + Amount of solution (2) × 60% = Amount of final solution × 40%
[tex]a\times \frac{20}{100}+(10-a)\times \frac{60}{100}=10\times \frac{40}{100}[/tex]
20a + 60(10 - a) = 400
20a + 600 - 60a = 400
600 - 40a = 400
40a = 600 - 400
a = [tex]\frac{200}{40}[/tex]
a = 5 liters
Therefore, Dr Khan will add 5 liters of acetic acid to get 40% acetic acid solution.
Solution:
Let the amount of 20% acetic acid, he added to get 10 liters of 40% solution = 'a' liters
Volume of 60% solution used will be = (10 - a) liters
Equation will be,
Amount of solution (1) × 20% + Amount of solution (2) × 60% = Amount of final solution × 40%
a*20/100+(10-a)*60/100=10*40/100
20a + 60(10 - a) = 400
20a + 600 - 60a = 400
600 - 40a = 400
40a = 600 - 400
a=200/40
a = 5 liters
Thus, Dr Khan need to create 5 liters of acetic acid to get 40% acetic acid solution.

The distance between port M and port N is 162m. A ship left port M with a speed of 45 mph. In 45 minutes another ship left port N and went towards the first ship with a speed of 36 mph. How long after the departure of the first ship will the two ships meet?
Answer:
900 min = 15 hours
Step-by-step explanation:
when we convert the velocities of the ships into miles/ min we get
45mph = 45m/60min = 0.75m/min
36mph = 36m/60min = 0.6m/min
The equations determining the distances of the ships from the port M (set at x=0) are
D1 = 0.75t (for 45mph ship)
D2 = 162 + 0.6(t-45) (for 36mph ship)
The solution to these equation lie at t= 900 minutes; therefore the two ships will meet 900 minutes after the departure of the first ship.

sarra binged watched 12 of the 15 episodes of " the dudes i dont dig"; what percent of the shows has she watched?
Answer:
Sarra watched 80% of the show.
Step-by-step explanation:
12÷15×100
Answer:
80%
Step-by-step explanation:
You have to take the total number of TV show episodes and divide it by the amount the person watched, in this case 15/12. Next, you have to multiply the answer you get by 100, in this case 0.8*100, this leads you to move the decimal point two places to the right giving you 80%.

How would you explain function notation to a friend?
Many students seem puzzled by function notation well after it has been introduced, and ask “why can’t we just write

How can you determine the distance between the corners without measuring it?
Answer:
The distance formula
Step-by-step explanation:
This was kind of vague, but I'll try my best.
You can use the distance formula! It is basically the pythagorean theorem.
Here's the steps,
1. draw a right triangle from the corners. If you have graph paper, this should be relatively easy.
2. locate the hypotenuse, that is the distance.
3. next use the pythagorean theorem/ distance formula (same thing)
4. Except, instead of a and b and c, replace them with
(Change in x)²+(change in y)²= distance²
Now plug in the values
Now you're done!
