So let X = ml of 8 % SOLUTION and Y = ml of 20 % SOLUTION
We know that X + Y must = 60 ml.
So first equation is X + Y = 60
The second equation is the statement of the problem
0.2 X + 0.08 Y = 0.1 x 60 = 6
Second equation reduces to
0.2 X + 0.08 Y = 6
Solve the two equations for X and Y and you have your answer.

A slot machine has 3 dials. Each dial has 40 positions, two of which are "Jackpot." To win the jackpot, all three dials must be in the "Jackpot" position. Assuming each play spins the dials and stops each independently and randomly, what are the odds of one play winning the jackpot?
Answer: there is a 1.2% of winning
Step-by-step explanation: there is a 1.2% chance of winning.
Step-by-step explanation:
The odds of one player that wins the jackpot should be 0.00156%.
Given that,
There are 3 dials.
In each dial, there are 40 positions.
So, the probability of receiving the jackpot should be \frac{1}{40}
40
1
Now the odds of one player that wins the jackpot should be
\begin{gathered}= \frac{1}{40} \times \frac{1}{40} \times \frac{1}{40} \\\\\end{gathered}
=
40
1

40

Therefore we can conclude that the odds of one player that wins the jackpot should be 0.00156%.

Which values are solutions of the inequality 7 > 2 - 4?
Choose ALL that apply.
6
7

11
20
Answer: This question does not make sense since 2 minus 4 is -2 and 7 > -2, which means this inequality is true by itself. There are no "solutions" to this inequality since there are no variables. Maybe you made a typo?
Edit: I found the actual question on the internet (it's 7 > z - 4) and the answers are 6, 7, and 10.
This is because simplifying this inequality gives us 11 > z, and 6, 7, and 10 are the only values that are below 11.
Answer:

The average length of a female dolphin is about 181 inches (in).
What is this length in feet (ft) and inches (in)?
The length is ft in.
Answer:
15 ft 1 in
Step-by-step explanation:
To convert inches into feet, we divide by 12.
12 goes into 181 fifteen times, so the # of feet is 15 feet.12 x 15 = 180.181 - 180 = 1, so the # of remaining inches is 1 inchTherefore, the answer is 15 ft 1 in.

The value of x from the triangle is x = 10.6
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be represented as ABC
Now , the measure of hypotenuse of the triangle = 15
Let the angle be θ = 45°
From the trigonometric relations ,
sin θ = opposite / hypotenuse
On simplifying the equation , we get
sin 45° = x / 15
where sin 45° = 0.7071
So , the value of x = 0.7071 x 15
The value of x = 10.6
Hence , the value of x from the triangle is x = 10.6

Step-by-step explanation:
Mr. Miller owns two hotels and is ordering towels for the rooms. He ordered 27 hand towels and 48 bath towels for a bill of $540 for the first hotel. He ordered 50 hand towels and 24 bath towels for a bill of $416 for the other hotel.
What is the cost of one hand towel and one bath towel?
A.
The cost of one hand towel is $9 and the cost of one bath towel is $4.
B.
The cost of one hand towel is $8 and the cost of one bath towel is $5.
C.
The cost of one hand towel is $5 and the cost of one bath towel is $8.
D.
The cost of one hand towel is $4 and the cost of one bath towel is $9.
This question is based on the concept of solving a two linear equation.
Thus, the cost of one bath towel is $9 and one hand towel is $4.
Given:
Number of ordered of hand towels is 27 and bath towels is 48 and for a bill of $540 for the first hotel.
Number of ordered of hand towels is 50 and bath towels is 24 and for a bill of $416 for the other hotel.
We need tom determined the cost of one hand towel and one bath towel.
According to the question:
Let the hand towels be h and bath towels be b.
Therefore, equation of first hotel is
27h + 48b = 540........(1)
Equation of second hotel is
50h + 24b = 416.........(2)
Now, solving both equation for h and b.
Equation (2) multiplying by -2.
-100 h -48 b = - 832..................(3)
Now, solve equation (1) and (3)
27h + 48b = 540 and -100h - 48b = - 832
⇒ -73 h = - 292
⇒ h = -292 / -73
⇒ h = 4
Therefore, the cost of 1 hand towel is $4.
Now, putting the value of h = 4 in equation (1).
⇒ 27(4) + 48b = 540
⇒ 108 + 48b = 540
⇒ 48b = 540 - 108
⇒ 48b = 432
⇒ b = 432/48
⇒ b = 9
Therefore, the cost of 1 bath towel is $9.
Thus, the cost of one bath towel is $9 and one hand towel is $4.

A music-streaming service charges $9 per month for a single user. Additional users within the same household can be added for $3 per month. Write an equation that shows how the monthly cost, y, depends on the number of additional users in the household, X. Do not include dollar signs in the equation. y=
The equation that shows the monthly cost is y = 9 + 3x
What is the equation that represents the monthly cost?
The monthly cost is a function of the charge for a single user and the cost of additional users. The monthly cost increases with the number of additional users.
The charge for a single user can be considered a fixed cost since it remains constant while the cost of the additional user can be considered a variable cost since it increases with the number of users.

(c) What is Euclid’s weight?
(d) Jake adopts a third dog, Riemann. Riemann weighs exactly twice what Euclid weighs. The combined weight of the three dogs is pounds. What is Riemann’s weight, and what is Pythagoras’s weight? Show your work.
Answer:The weight of Euclid is 10.625 pounds, and the weight of Riemann is 21.25 pounds.
Let the current weight of Euclid = x
Let the current weight of Pythagoras = T
Let the January weight of Pythagoras = y
The expression that represents the given scenario is written as;
when Pythagoras lost 13 pounds: T = y - 13
when Pythagoras gains 1.2 times Euclid's weight: = T + 1.2x
when Pythagoras weight is 1/4 pound less than weight in January:
T + 1.2x + 0.25 = y
y- 13 + 1.2x + 0.25 = y
1.2x - 12.75 = 0
Euclid's weight is calculated as follows;
1.2x = 12.75
The weight of Riemann is calculated as follows;

It takes 56 pounds of seed to completely plant an 8-acre field. How many acres can be planted per pound of seed?
Answer:
7
Step-by-step explanation:
8 divided by 56 equals 7
Answer:
1/7 acre
Step-by-step explanation:
The number of acres planted is presumed to be proportional to the number of pounds of seeds:
acres/pounds = 8/56 = x/1
x = 1×8/56 = 1/7
1/7 acre can be planted per pound of seed.
_____
Additional comment
When you recognize that 56 = 8×7, there is a tendency to want to divide 56 by 8. That would result in the unit rate ...
(56 lb)/(8 ac) = 7 lb/ac
That is, it takes 7 pounds of seed to plant 1 acre. The question asks how many acres can be planted with 1 pound. Clearly, that is 1/7 of the amount of seed required for 1 acre, so 1 pound will plant 1/7 acre.
