a laboratory technician needs to make a 90 liter batch of a 20% acid solution.
How can the laboratory technician combine batch of an acid solution that is pure acid with another that that is 10% to get the desired concentration
:
Let x = amt of pure acid
the result is to be 90 liters, therefore
(90-x) = amt of 10% solution required
:
.10(90-x) + x = .20(90)
9 - .1x + x = 18
.9x = 18 - 9
.9x = 9
x = 9/.9
x = 10 liters of pure acid required
then
90 - 10 = 80 liters of the 10% solution required
:
:
See if that checks out
.10(80) + 10 = .20(90)
8 + 10 = 18; confirms our answer

For the given figure, x = 23° and y = 129°
Parallel lines:
Parallel lines are lines that always stay the same distance apart and never meet.
Transversal line :
A transversal is a line that crosses two or more other lines.
given,
∠TLN = (3x - 18)°
∠MZQ = (5x + 14)°
∠NLM = y°
Now,
∠MZP + ∠MZQ = 180° (Linear Pair)
∠MZP = 180° - ∠MZQ ...........(I)
again,
∠NLM + ∠TLN =180° ...........(II) (Linear Pair)
As, ∠TLN = ∠MZP (Corresponding Angle)
(3x - 18)° = 180° - ∠MZQ
(3x - 18)° = 180° - (5x + 14)°
3x + 5x = 180° - 14° + 18°
8x = 184°
x = 184 / 8
x = 23°
From (II),
∠NLM + ∠TLN =180°
y° + 3x - 18° = 180°
y = 180 - 3x + 18
= 180 - 3* 23 + 18
= 180 - 69 +18
y = 129°

The 150 Student Council consists of 6 members: 1 in-state senior, two in-state stude who are not seniors, 1 out-of-state senior, and two out-of-state students wn not seniors. In how many ways can the officers of the Student Advisory Bog selected from these 6 Student Council members if they must obey the rules that if individual members switch offices, this produces a different Board.
Answers
Answer:
P (6, 3) – p (6, 4) – p (6, 2) = 270
Step-by-step explanation:
The 150 student council consist of 6 members.
Included at least one in-state student and at least one senior.
There are total 6 members: in which,
1 in- state senior,
2 in state non-senior,
1 out of state senior and
2 out of state non-senior.
Total member are 6 and we selected 3. So p (6, 3)
The way team will have only non-senior = p (6, 4)
The way team will have out of state = p (6, 2)
Subtracting the total we get:
P (6, 3) – p (6, 4) – p (6, 2) = 6x5x4 – 6 x 5 x 4 x3 – 6x 5
= 30 x 4 – 30 x 12 – 30
= 120 – 360 – 30
=- 270

Wyatt was out at a restaurant for dinner when the bill came. He wanted to leave a tip of 19%. What number should he multiply the cost of the meal by to find the total plus tip in one step?
Answers
Answer:
The cost of the meal should be multiplied by 1.19.---------------------------------------
Let the cost of the meal be x.
Adding a tip of 19%:
x + 19% = x + 0.19x = x (1 + 0.19) = 1.19xAnswer:
Wyatt should multiply with 1.19.
Step-by-step explanation:
Forming the expression,
→ 1 + (19% of 1)
Now the required number is,
→ 1 + (19% of 1)
→ 1 + ((19/100) × 1)
→ 1 + (19/100)
→ 1 + 0.19 = 1.19
Hence, required number is 1.19.

\(m=\frac{10.5-7}{3-2}=\frac{3.5}{1}=3.5\)The constant rate of the relationship is 3.5. It seems like the relationship is a proportional relationship, we can describe it as follows:
\(y=kx\)Where k is the constant rate or constant of proportionality, that in this case is 3.5. The relationship can be described as:

Write the nth rule for each geometric sequence.4) -3, 1, -1/3, 1/9...
Answers
In a geometric sequence each term is found by multiplying the previous term by a constant.
To find the nth term in a geometric sequence we use:
\(a_n=ar^{n-1}\)where a is the first term and r is the common ratio.
To find the common ratio we can divide the second term by the first:
\(\frac{1}{-3}=-\frac{1}{3}\)and the third one by the second:
\(\frac{-\frac{1}{3}}{1}=-\frac{1}{3}\)we notice that this in fact is the common ratio. Now we plug it in the formula above, therefore the geometric sequence is:

Find the present value of an annuity which pays ` 200 at the end of each 3 months for 10 years assuming
money to be worth 5% converted quarterly?
(a) ` 3473.86
(b) ` 3108.60
(c) ` 6265.38
(d) None of thes
Answers
The present value of the annuity is approximately `7032.08. The correct answer is option (d) None of these.
To find the present value of an annuity, we can use the formula:
PV = PMT * (1 - (1 + r)^(-n)) / r
Where PV is the present value, PMT is the periodic payment, r is the interest rate per period, and n is the number of periods.
In this case, the periodic payment is `200, the interest rate is 5% (or 0.05) converted quarterly, and the number of periods is 10 years, which equals 40 quarters.
Plugging in these values into the formula, we get:
PV = 200 * (1 - (1 + 0.05)^(-40)) / 0.05
Simplifying the equation, we find:
PV ≈ 200 * (1 - 0.12198) / 0.05
PV ≈ 200 * 0.87802 / 0.05
PV ≈ 35160.4 / 0.05
PV ≈ 7032.08
Therefore, the present value of the annuity is approximately `7032.08.

Answers
Answer:

Answer:
Restaurant A's chicken salad has 7.7 grams of fat.
Restaurant B's chicken salad has 61.6 grams of fat.
Restaurant C's chicken salad has 7.7 grams of fat.
Step-by-step explanation:
Restaurant A = C
Restaurant B = 8 × Restaurant A
Total Grams of Salad = 77
Let Reataurat A and C be x
and Reataurant B be 8x
so
A + B + C = 77
x + 8x + x = 77
2x + 8x = 77
10x = 77
x = 77 ÷ 10
x = 7.7
Restaurant A's chicken salad has 7.7 grams of fat.
Restaurant B's chicken salad has 61.6 grams of fat.
Restaurant C's chicken salad has 7.7 grams of fat.

which of the following best describes the graph shown below
Answers
The given graph is of a function because for a particular value of y, there is a fixed value of 'x'.
Also, since there are two different values of x having same value for y, so the function is not one-to-one. For example, If y = f(x) is the function, then f(1.5) = f(-1) = 3.
Therefore, the graph represents a function, but it is not one-to-one.
Thus, the correct option is (A) THE ANSWER Is A
Answer:
A
Step-by-step explanation:
In the graph shown, no two y values share an x value. If you were to pass a vertical line through it at any point, it would only intersect it once, which makes it a function.
Many x values in the graph share y values; if you were to pass a horizontal line through it, it would intersect it more than once at certain points, which makes it NOT one-to-one.
This means that the answer is A: This is the graph of a function, but it's not one-to-one.
