Two solutions of salt water contain 0.06% and 0.21% salt respectively. A lab technician wants to make 1 liter of solution which contains 0.12% salt. How much of each solution should she use?
Answer:
The first solution must have 0.6 l and the second one 0.4 l.
Step-by-step explanation:
The volume of the first solution will be called "x", while the one from the second will be "y". The salt content on the first solution is "0.0006*x", while the salt content on the second solution is "0.0021*y", and the sum of these two values must be the same as the one in the final solution, so we have:
0.0006*x + 0.0021*y = 0.0012
And the sum of volumes must be equal to 1 liter.
x + y = 1
We have the equation system:
x + y = 1 (1)
0.0006*x + 0.0021*y = 0.0012 (2)
Isolating the "x" variable in the first equation and applying it in the second we have:
x = 1 - y
0.0006*(1-y) + 0.0021*y = 0.0012
0.0006 - 0.0006*y + 0.0021*y = 0.0012
0.0015*y = 0.0006
y = 0.0006/0.0015 = 0.4
x = 1 - 0.4 = 0.6
The first solution must have 0.6 l and the second one 0.4 l.

if you flip a coin and roll a 6 sided die, what is the probability that you will flip a tails and roll 2
Answer:
1/12.
Step-by-step explanation:
6 sides and 2 sides. 2 possible outcomes for each side of the dice
Answer:
[tex]\frac{1}{12}[/tex]
Step-by-step explanation:
The combinations:
heads and 1, heads and 2, heads and 3, heads and 4, heads and 5, heads and 6, tails and 1, tails and 2, tails and 3, tails and 4, tails and 5, tails and 6
There are 12 combinations (count if you don't believe me). An easy way to find this is by multiplying the number of things you can get from the coin (2)and the number of things you can get from the die (6).There is only one combination where you can get tails and roll 2, so the probability will be [tex]\frac{1}{12}[/tex]A cylinder has a volume of 792cm3 and a radius of 6m find its height
Answer:
Step-by-step explanation:
7
Answer:
≈ 7
Step-by-step explanation:
the formula of the volume of a cylinder is:
V = π r^2 * h
792 = 3.14 * 6^2 *h
so first divide by 6^2 (or 36) on both sides so you can start to isolate h
36/36 = 1 and 792/36 = 22
22 = 3.14 *h
now divide by 3.14 to get h by itself
3.14/3.14 = 1 and 22/3.14 ≈ 7
the answer is approximately 7 and precisely 7.002817496

Ed is constructing the perpendicular bisector of a segment on his paper. He just finished
labeling the points of intersection of the two arcs that he drew. What is his next step?
Answer:
The next step is to draw a line connecting the two labelled points, that is from one side of the line to be bisected to the other
The line drawn in the above step, from the two labelled points is the perpendicular bisector of the segment
Step-by-step explanation:
To draw a perpendicular bisector of a segment, we have;
1. Ensure the compass is opened to more than half of the length of the segment to be bisected
2. Draw arcs of the same radius with center at the ends of the line to be bisected
3. Label the points where the arcs drawn from both ends cross each other on opposite sides of the line
4. Draw a line connecting the two labelled points, that is from one side of the line to be bisected to the other
5. The line so drawn from the two labelled points is the perpendicular bisector of the segment.
Lewis was driving at 90 km per hour when he sneezed.
During the sneeze, his eyes were closed for half a second.
Work out how many metres he travelled in this time.
Answer:
12.5 m
Step-by-step explanation:
recall that 1 km = 1000 m
hence 90 km/h is equivalent to 90 km/h x 1000 m/km = 90,000 m/hr
also recall that 1 hour = 60 x 60 = 3600 s
hence 90,000 m/hr is equivalent to 90,000 m/hr x (1/3600) hr/s = 25 m/s.
given that is eyes were closed for 0.5 s.
in 0.5s, he travelled :
0.5s x 25 m/s = 12.5 m

En 16 días se consume 1/8 de la carga de una batería. ¿Cuantos se consumirá en 48 días?
Answer: 3/8
Step-by-step explanation:
1/8 of the charge of a battery is consumed in 16 days. How will be consumed in 48 days?
So, to answer this question we simple have to apply a proportion:
(1/8 )/16 = charge consumed /days
For 48 days= x /48 days
(1/8 )/16 = x/48
Solving for x (charge)
[(1/8 )/16] 48 = x
3/8 =x

Answer:
x = ± sqrt(-49)
or x = ± 7i
Step-by-step explanation:
x^2 +49 = 0
Subtract 49 from each side
x^2 +49 -49 = 0-49
x^2 = -49
Take the square root of each side
sqrt(x^2) = ± sqrt(-49)
x = ± sqrt(-49)
We have to complex numbers to solve
x = ± sqrt(-1) sqrt(49)
sqrt(-1) = i
x = ±i *7
x = ± 7i

Ashley said 3/4 of her stuffed animals have buttons eyes. Pam said Ashley has 15 stuffed animals. is it possible that Pam is correct? Please explain.
Answer: No it is not possible
3/4 has a denominator of 4, which is not a factor of 15. This means that there is a contradiction somewhere. Note how (3/4)*15 = 11.25 is not a whole number. So if Ashley did have 15 stuffed animals, then 3/4 of that wouldn't be a whole number and it would contradict what Ashley is stating. The same can be said in reverse: if Ashley's statement is correct, then there's no way Pam is correct as well.

The cost of 24 bottles of water is $6. How much does it cost for 10 bottles of water?
Find the unit rate: 24 water bottles ÷ 6 dollars total = $0.25 a water bottle
Next, take the rate per water bottle and multiply it by ten: $0.25 a water bottle x 10 bottles of water = $2.50 total
So, this gives you your final answer. Ten bottles of water cost you $2.50!

There are 4 fewer blue pens in a box than black pens. There are 15 black pens in each box.
How many blue pens are in 3 boxes?
Add 15 and 4. Then multiply the sum by 3.
Subtract 4 from 15. Then multiply the difference by 3.
Subtract 4 from 15. Then divide the difference by 3.
Answer:
the answer is: "Subtract 4 from 15. Then multiply the difference by 3."
Step-by-step explanation:
If there are 4 fewer blue pens in a box than black pens, and there are 15 black pens in each box, then that means there are 11 blue pens in each box.
So then, how many blue pens are in 3 boxes? There are 33 blue pens in 3 boxes, you can find this out by multiplying, 11 by 3.
the numerical answer is:
11 x 3 = 33
or, 3 x ( 15 - 4)
