The chemist has three different acidic solutions. The first solution contains 20% acid, the second contains 35% acid, and the third contains 80% acid. She created 54 liters of a 50% acid mixture, using all 3 solutions. The number of liters of 80% solution used is 2 times the number of liters of 35% solution used.
Let the amounts of 20% solution, 35% solution, and 80% solution used be x, y, and z. We already know that z = 2y. We can write equations as given below.
The sum of the volumes must be equal to the final volume.
x + y + z = 54
x + y + 2y = 54
x = 54 - 3y
Now we will write the equation using the concentrations of the acid.
50%*54 = 20%*x + 35%*y + 80%*z
27 = 0.2(54 - 3y) + 0.35y + 0.8(2y)
2700 = 20(54 - 3y) + 35y + 80(2y)
2700 = 1080 - 60y + 35y + 160y
1620 = 135y
y = 1620/135 = 12

Determine the convergence of divergence of the sequence. If the sequence converges, find its limit.
The sequence converges and its limit is zero
What is a sequence?A sequence is an ordered set of numbers governed by a rule.
What is the limit of a sequence?The limit of a sequence is the value the sequence approaches
What is convergence of a sequence?The convergence of a sequence is when the sequence approached a definite value
What is divergence of a sequence?The divergence of a sequence is when the sequence does not approach a definite value.
How to determine the convergence of divergence of the sequence?Since we have the sequence (√3 - √1), (√4 - √2), (√5 - √3), (√6 - √2), We need to find the general term of the sequence.
Observing this, we find that the general term Uₙ = √(n + 2) - √n
To determine if the limit converges or diverges, we take the limit of the sequence as n → ∞.
So,
[tex]\lim_{n \to \infty} U_n = \lim_{n \to \infty} \sqrt{n + 2} - \sqrt{n} \\= \lim_{n \to \infty} \sqrt{n + 2} - \lim_{n \to \infty} \sqrt{n} \\= \sqrt{\infty - 2} - \sqrt{\infty} \\= \sqrt{\infty} - \sqrt{\infty} \\= \infty -\infty[/tex]
Since this is an indeterminate form, we use L'hopital's rule to find the limit.
Uₙ = √(n + 2) - √n
= √n{√[(n + 2)/n] - 1}
= √n÷ 1/{√[(1 + 2/n] - 1}
Differentiating, we have
lim n → ∞ Uₙ = lim n → ∞ d√n/dn ÷ d(1/{√[(1 + 2/n] - 1})/dn
= 1/(2√n)/-√[(1 + 2/n] - 1})⁻² × 1/2√(1 + 2/n] × (-2/n²)
= n²[√(1 + 2/n] - 1})²/(2√n)√(1 + 2/n]
= n²[√(1 + 2/n] - 1})²/(2√n)√(1 + 2/n)]
Dividing through by n², we have
= n²[√(1 + 2/n] - 1})²/n² ÷ (2√n)√(1 + 2/n)]/n²
= [√(1 + 2/n] - 1})² ÷ (2(√n)³√(1 + 2/n³)]
Dividing both the numerator and denominator by (√n)³, we have
= [√(1 + 2/n] - 1})²/(√n)³ ÷ (2(√n)³√(1 + 2/n³)]/(√n)³
= (1 + 2/n] - √(1 + 2/n] + 1)/(√n)³ ÷ [2√(1 + 2/n³)]
= (1(√n)³ + 2/n²] - √{(1 + 2/n]/n)³} + 1/(√n)³) ÷ [2√(1 + 2/n³)]
= (1(√n)³ + 2/n²] - √{(1/n³ + 2/n⁴} + 1/√n)³) ÷ [2√(1 + 2/n³)]
So, lim n → ∞ Uₙ = lim n → ∞ (1(√n)³ + 2/n²] - √{(1/n³ + 2/n⁴} + 1/√n)³) ÷ [2√(1 + 2/n³)]
= (1(√∞)³ + 2/∞²] - √{(1/∞³ + 2/∞⁴} + 1/√∞)³) ÷ [2√(1 + 2/∞³)]
= (0 + 0] - √{(0 + 0} + 0) ÷ [2√(1 + 0)]
= (0 - 0 + 0)/2
= 0/2

Write a recursive formula: 3, 5, 7, 9, 11, 13, 15, 17, 19, 21
Answer:
[tex]a_1=3[/tex]
[tex]a_n=a_n_-_1+2[/tex]
Step-by-step explanation:
Recursive formula : an = a(n-1) + d
where d = common difference , an = nth term, and n = number of terms
Because we are just writing the recursive formula rather than the explicit formula, the only defined term will be "d" or the common difference.
Here, the common difference is +2. This is evident as you must add 2 to get to 5 and then add 2 to get to 7 etc.
So d = 2
Plugging this into the recursive formula we get an = a(n-1) + 2
Also it's very important to state the first term which is 3 so a1 = 3

What are the dimensions of the pool? If the depth of the pool is 6 feet, how much water can the pool hold if the height of water is 1 foot below the top of the pool?
Convert cubic feet to gallons
The length of the swimming pool is 30 feet
The width of the swimming pool is 15 feet
The volume of the swimming pool is 16875 gallons
Given,
Length of the rectangular swimming pool = 2x
Width of the rectangular swimming pool = x
A small concrete walkway surrounds the pool.
The width of the walkway = 2 feet
The area of the walkway = 196 square feet
We have to find the dimensions of the pool;
Here,
Area of rectangle = length x width
Area of walkways = (4x + 8x) + 4 x 4 = 196
12x + 16 = 196
12x = 196 - 16
12x = 180
x = 180/12
x = 15
That is,
Width of the pool is 15 feet
Length of the pool = 2 × x = 15 x 2 = 30 feet
Now,
If the depth of the pool is 6 feet, we have to find the amount of water that the pool can hold if the height of water is 1 foot below the top of the pool.
That is,
Volume of pool = length x width x depth
Here, depth = 6 - 1 = 5 feet

420.9536 Find the digits in the ones place, in the tenths place, and in the thousandths place for the following number.
Answer:
ones: 0
tenths: 9
thousandths: 3
Step-by-step explanation:
Because 0 is at the beginning of the whole "part" of the number, it is a "one" in place value (confusing right??) for example, in the number 54,743, 3 would be the digit in the ones place.
Because 9 is one decimal place across the example number, it is a tenth - because you would need 10 lots of 0.1 in order to make a whole number.
Because 3 is three decimal places across the example number, it is a thousandth - because you would need 1000 lots of 0.001 to make a whole number.
A good way of remembering these decimal place values is by using the number of zeros after 10, 100, 1,000, 10,000, and so on (one zero is a ten-th, two zeros is a hundred-th, etc, etc.)

the dimensions of the dumpster that will minimize its surface area
length l = 6.32
width w = 1.58
height h = 0.39
Length = l
width = w
height = h
given that length is four times its width
l = 4w
Now, the formula for the surface area of a cube is;
S = 2lh + 2lw + 2wh
substitute l = 4w in the above equation
S = 2(4w)h+2(4w)w+2wh
S = 8wh+8[tex]w^{2}[/tex]+2wh
S = 10wh + 8[tex]w^{2}[/tex]
formula for the volume of a cube is;
V = lwh
now substitute l=4w in the above equation
V = (4w)wh
V = 4[tex]w^{2}[/tex]h
h = 4[tex]w^{2}[/tex]/V
Put V/2w² for h in the surface area equation to get;
S= 8w² + 10w(V/4w²)
= 8w² + 5V/2w
given that volume V = 25.6 substitute that in the above equation
S = 8w² + 5(25.6)/2w
= 8w² + 128/2w
Since we want to minimize the surface area, let us find the first derivative of S to get;
S' = 16w - 128/2w²
At S' = 0
0 = 16w- 128/2w²
16w = 128/2w²
32w³ = 128
w³ = 128/32
w³ = 4
w = [tex]\sqrt[3]{4}[/tex]
w = 1.58 yds
since l = 4w substitute the value of w in that
l = 4(1.58) = 6.32
h = 4[tex]w^{2}[/tex]/V = 4([tex]1.58^{2}[/tex])/25.6

the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Determine the range of the following graph:
The range of the given function is represented as {y | -5 ≤ y ≤ 5 , y ∈ R} .
Range of a function is defined as the possible values of y or the dependent variable in relation to the values of x.
Here from the graph we can see that the greatest value y achieves is 5.
The lowest value of y from the graph is -5 for all the values of x.
Hence the range will be {-5 ≤ y ≤ 5}
Now the graph is continuous, so we accept all values of y, hence y ∈ R .
Therefore the range will be: {y | -5 ≤ y ≤ 5 , y ∈ R} .
The set of all possible values for the results of the dependent variable, or the entire set of all possible values when the domain is substituted, is the range of a function.
The steps to find the range is:
