Convert the capacity of 5 liters
Based on the above, the capacity of a 5-liter tin is about 500 cm³.
What is the capacity?To be able to convert the capacity of a 5-liter tin to its volume in cm³, One need to use the conversion factor that is, 1 liter is equivalent to 100 cm³.
So, to be able to calculate the volume of a 5-liter tin in cm³, one have to multiply the capacity (5 liters) by the conversion factor (100 cm³/liter):
Volume in cm³ = 5 liters x 1000 cm³/liter
= 500 cm³
Therefore, the capacity of a 5-liter tin is about 500 cm³.

Avery and Seth, the boy she was babysitting, were playing basketball together. Her score was 18 points, and his score was 20 points. Avery wanted to make the game more fair, so she called a time-out and modified the rules a bit. Avery explained that, for the rest of the game, she would get 3 points per basket, and Seth would get 1 point per basket. Then they played a bit longer. After the time-out, they both made the same number of baskets and ended up with a tied score. How many points did each person have at the end? How many baskets did each person make after the time out?
After the time-out, Avery and Seth each made 1 basket, and their scores were tied at 21 points each.
Let's denote the number of baskets made by Avery after the time-out as "A" and the number of baskets made by Seth as "S."
Since Avery gets 3 points per basket and Seth gets 1 point per basket after the time-out, we can set up the following equation based on the given information:
3A + 18 = S + 20.
Since they ended up with a tied score, we can also set up the equation:
3A + 18 = S + 20 + (S - 1)
Simplifying the second equation, we get:
3A + 18 = 2S + 19
Combining the two equations, we have:
S + 20 = 2S + 19
Simplifying, we find:
S = 1
Substituting this value of S back into one of the equations, we get:
3A + 18 = 1 + 20
3A + 18 = 21
Simplifying further, we find:
3A = 3
A = 1
Therefore, after the time-out, Avery and Seth each made 1 basket, and their scores were tied at 21 points each.

Lorena and Julio purchased a home for $205,950. Their tax rate is 1.5%.
Let's calculate how much their monthly taxes will be.
Assessed value is the dollar value of a property for the purposes of taxation, according to the county tax assessor's office.
By multiplying the assessed value by the tax rate we get Property taxes.
Then, divide this number by 12 to obtain the monthly tax.
Let's calculate the annual tax amount first.
Multiplying the assessed value by the tax rate.
$200,500 * 1.5% = $3,007.50
Now let's calculate the monthly tax amount.
$3,007.50 / 12 = $250.62

Two points A and B on a plan represent two localities 12 m apart. Given that the segment AB is 6cn long, find the scale used to draw the plan.
Answer:
The scale is 1:200
Step-by-step explanation:
On the plan we have the drawing as 6 cm
In real representation, we have the distance as 12 m
Firstly we have to convert to same unit
In this case, we use the cm for convenience
Mathematically, 100 cm is 1 m
Thus, 12 m
will be 12 * 100 = 1,200 cm
So, we have the ratio as;
6 cm : 1,200 cm
and that is 1:200 (since 6/1200 = 1/200 and in ratio form, we have that as 1:200)

What is quadratic equation?A quadratic equation, or sometimes just quadratics, is a polynomial equation with a maximum degree of two. It is written as ax² + bx + c = 0, with x being the unknown variable and a, b, and c being the constant terms.
The limit of φ(x) as x tends to negative infinity depends on the behavior of the solution φ(x) to the given initial value problem.
To determine the behavior of the solution, we can consider the characteristic equation associated with the differential equation:
r² + 22r + 146 = 0
Solving this quadratic equation, we find that the roots are complex conjugates:
r = -11 + 5i and r = -11 - 5i
Since the roots are complex, the solution will involve complex exponential functions. The real part of the complex exponential will decay as x tends to negative infinity. Therefore, the limit of φ(x) as x tends to negative infinity is 0.
So, the correct answer is d. The limit of φ(x) as x tends to -[infinity] is 0.

Line N P, is parallel to line O.U, the measure of angle N S R = 5 X plus 12, the measure of angle S T U = 3 X plus 8. What is the measure of angle O. T. Q.
The measure of angle OTQ is 166 degrees.
What are parallel lines?
Parallel lines are two or more lines in a plane that never intersect each other, no matter how far they are extended.
Since line NP is parallel to line OU, we can conclude that angles NRS and STU are corresponding angles, meaning they have the same measure. Therefore:
5X + 12 = 3X + 8
2X = 4
X = 2
Now that we know X, we can find the measure of angle STR:
3X + 8 = 3(2) + 8 = 14
Since angle STR is a straight angle with angle OTQ, we can find the measure of angle OTQ by subtracting the measure of angle STR from 180 degrees:
180 - 14 = 166
Therefore, the measure of angle OTQ is 166 degrees.

whenever n is a nonnegative integer. (b) For which nonnegative integers n is 2n+3≤2
n
? Prove your answer.
The answer to part (b) is that the inequality holds true for all nonnegative integers n
To prove the equation 1/2 + 3/2 + 5/2 + ... + (2n+1)/2 = (3(n+1)(2n+1)(2n+3))/8, we can use mathematical induction.
Step 1: Base Case
For n = 0, we have:
LHS: 1/2 = 1/2
RHS: (3(0+1)(2(0)+1)(2(0)+3))/8 = (3(1)(1)(3))/8 = 9/8
The equation holds true for n = 0.
Step 2: Inductive Hypothesis
Assume that the equation holds true for some arbitrary positive integer k, i.e.,
1/2 + 3/2 + 5/2 + ... + (2k+1)/2 = (3(k+1)(2k+1)(2k+3))/8
Step 3: Inductive Step
We need to prove that the equation holds true for n = k+1, i.e.,
1/2 + 3/2 + 5/2 + ... + (2(k+1)+1)/2 = (3((k+1)+1)(2(k+1)+1)(2(k+1)+3))/8
Starting from the left-hand side (LHS):
LHS: 1/2 + 3/2 + 5/2 + ... + (2(k+1)+1)/2
= (1/2 + 3/2 + 5/2 + ... + (2k+1)/2) + (2(k+1)+1)/2
= [(3(k+1)(2k+1)(2k+3))/8] + (2(k+1)+1)/2 [Using the inductive hypothesis]
= (3(k+1)(2k+1)(2k+3) + 4(k+1)+2)/8
= [(k+1)(2k+1)(6k+9+4+2)]/8
= [(k+1)(2k+1)(6k+15)]/8
= [(k+1)(2k+1)(2k+3)]/8 * 3
= (3((k+1)+1)(2(k+1)+1)(2(k+1)+3))/8
Both sides are equal, so the equation holds true for n = k+1.
Step 4: Conclusion
By mathematical induction, we have proven that for any nonnegative integer n, the equation 1/2 + 3/2 + 5/2 + ... + (2n+1)/2 = (3(n+1)(2n+1)(2n+3))/8 holds true.
(b) To find the values of n for which 2n+3 ≤ 2^n, we can simplify the inequality:
2n+3 ≤ 2^n
2n+3 ≤ 2 * 2 * 2 * ... * 2 (n times)
2n+3 ≤ 2^n
Since the left-hand side (LHS) is a constant (3) and the right-hand side (RHS) is an exponential function, we can compare their values for different nonnegative integers n to determine when the inequality holds true.
For n = 0:
LHS: 2^0+3 = 4
RHS: 2^0 = 1
4 > 1, so the inequality holds true for n = 0.
For n =
1:
LHS: 2^1+3 = 5
RHS: 2^1 = 2
5 > 2, so the inequality holds true for n = 1.
For n = 2:
LHS: 2^2+3 = 7
RHS: 2^2 = 4
7 > 4, so the inequality holds true for n = 2.
We can continue this process and observe that for any nonnegative integer n, the inequality 2n+3 ≤ 2^n holds true. Therefore, the answer to part (b) is that the inequality holds true for all nonnegative integers n.
