169 divided, simplified
The number 169 is called the numerator or dividend, and the number 3 is called the denominator or divisor. The quotient of 169 and 3, the ratio of 169 and 3, as well as the fraction of 169 and 3 all mean (almost) the same: 169 divided by 3, often written as 169/3.
What is denominator or divisor?The number that is on top is called the numerator, and the number on the bottom is called the denominator (the prefix 'de-' is Latin for reverse) or divisor. These two numbers are always separated by a line, which is known as a fraction bar. This way of representing fractions is called display representation.
When we divide two numbers, the number that is being divided is the dividend, whereas the number by which we divide is the divisor. For example, 12 candies are to be divided among 3 children. So we have 12 ÷ 3. Here, 12 is the dividend, and 3 is the divisor.

If x and y are positive integers less than 10, and 3x + 2y = 13, using a guess-and check method, what could be the value of y?
Find one of the two possible correct answers. Enter a number for y only!
Hint: Substitute numbers in for x and y and find a pair that works!
y = ____
Step-by-step explanation:
we can do even a little bit better than wild guessing and trying.
3x + 2y = 13
tells us that the sum of 2 terms is an odd number.
that means one term has to be odd and the other even, as only then their sum will be odd.
2y is because of the included factor 2 an even number. always.
so, 3x has to be odd.
and that means x has to be odd too. because an even number multiplied with any number is always even.
so, x can only be 1 or 3. because 3×5 = 15 (3×7 = 21, 3×9 = 27) and already too big for the sum 13.
so, for x = 1 we have
3×1 + 2y = 13
3 + 2y = 13
2y = 10
y = 5
for x = 3 we have
3×3 + 2y = 13
9 + 2y = 13
2y = 4
y = 2
so, the answer is either y = 2 or y = 5.

b. As part of the assignment, you need to make a ratio table using the scale factor 0.5 nm

where the question marks (?) are? Show all your work.
Nanometers Inches
? 5
0.5 10
1 20
3 ?
Answer: The ratio between the units of measurement of nanometers and inches is 0.5 nm to 10 inches. This means that for every 0.5 nanometers, the equivalent measurement in inches is 10 inches.
We can use this ratio to find the conversion of other values from nanometers to inches as well.
We know that 1 nm = 20 inches, we can multiply the value 1 by 20 to get 20 inches
So 3 nm will be 3 * 20 = 60 inches
so, the value that can be placed in the ratio table where the question marks (?) are would be 1 nm = 20 inches
and 3 nm = 60 inches.

Write the inequality using interval notation ?To arrange the intervals in interval notation, use brackets and parenthesis.The number at the extremity of the interval is included when it is enclosed in brackets [or], and it is not included when it is enclosed in parentheses (or). We always use parentheses for infinite.For instance:Numbers higher than a and less than or equal to b are not included in this interval, so a x b applies.In this case, the expression x > 0 refers to numbers greater than or equal to zero.Since there is no upper bound specified, we must use a right parenthesis with an infinite symbol and a left bracket for zero in interval notation (since it includes the integer). Therefore, this is [0,] in interval notation.We first create a number line on which the extremes of the interval or intervals can be seen before graphing this.If one of them is an endless symbol, we must indicate that with an arrow, using a left arrow for - and a right arrow for.

After 16 years in an account with a 5.9% annual interest rate compounded continuously, an investment is worth a total of $37,950.24. What is the value of the principal investment? Round the answer to the nearest penny. $14,765.24 $14,859.72 $23,185.00 $23,090.52
Answer: We can use the formula A = Pert to find the value of the principal investment P
Where A is the future value of the investment, r is the annual interest rate, t is the number of years, and e is the mathematical constant approximately equal to 2.718
In this case,
A = 37950.24, r = 0.059, t = 16
We can plug in the given values into the formula and solve for P:
37950.24 = P * e^(0.059 * 16)
To find the value of P we will divide both sides by e^(0.059 * 16)
P = 37950.24 / e^(0.059 * 16)
using the calculator to find the value of e^(0.059 * 16) gives 1.966862298
P = 37950.24 / 1.966862298
The value of P is $19,169.99.
Rounded to the nearest penny $19170

Determine the average rate of change of B from t = 0 $ to t = 332 s. Time (s) Concentration of A (M) 0 0.670 166 0.415 332 0.160
A -> 2B rateB =__________________ M/s
The rate of B is -0.003072 M/s.
The average rate of change is a measure of how much a quantity changes over a certain period of time. In this case, we are looking at the concentration of B, and we want to know how much it changes over the time interval from 0 to 332 seconds. To calculate this, we first need to determine the initial and final concentrations of B at these two points in time.
From the given data, we know that
the initial concentration of B at t = 0 is 0.670 Mthe final concentration of B at t = 332 s is 0.160 M.Once we have these values, we can calculate the change in concentration of B by subtracting the initial concentration from the final concentration: 0.160 M - 0.670 M = -0.510 M. This tells us that the concentration of B decreases by 0.510 M over the time interval from 0 to 332 seconds.
Next, we need to divide this change in concentration by the length of the time interval to get the average rate of change. The length of the time interval is the difference between the final and initial time: 332 s - 0 s = 332 s. So, the average rate of change of B is (-0.510 M) / (332 s) = -0.001536 M/s. This tells us that the concentration of B decreases by 0.001536 M per second on average over the given time interval.
As we know that the reaction is of form A -> 2B, the rate of formation of B is equal to twice the rate of A.
So, Rate of B = 2* Rate of A = 2*(-0.001536) = -0.003072 M/s
