In your own words, explain the place value relationship when the same two digits are next to each number in a multi-digit number
The relationship of the two of the same digits that are next to each other in a multi-digit number lies in their place value, wherein the digits from the decimal point that is to the left, is 10 times of larger value compared to the digit in their left. And from the decimal point to the right, it is 10 times of small value that the digit in their right.
Let’s see an example:
123.45, wherein 1 is hundreds, two is tens, 3 is ones, and then after the
decimal points, is where 4 is the tenths and 5 is the hundredths.
Take note of each place value that is next to each other since each value
is 10 times in difference.

Mr. Brown owned a house a house, which he rented for $60 a month. The house was assessed for $9000. In 1975 the rate of taxation was increased from $25 to $28 per $1000 assessed valuation. By what amount should the monthly rent have been raised to absorb the increase in that year's taxes?
Mr. Brown should increase the monthly rent by $2.25 to cover the additional annual property tax caused by the tax rate increase from $25 to $28 per $1000 assessed valuation on a $9000 house.
The student is asking for a calculation of how much the monthly rent of a house should be increased to cover the additional property tax imposed when the tax rate was increased from $25 to $28 per $1000 assessed valuation. The house is valued at $9000.
First, we calculate the initial annual tax by multiplying the assessed valuation by the initial tax rate:
Initial annual tax = $9000 / 1000 times $25 = $225
Then we calculate the new annual tax with the increased rate:
New annual tax = $9000 / 1000 times $28 = $252
The increase in the annual tax amount is:
Increased tax amount = New annual tax - Initial annual tax = $252 - $225 = $27
To find the monthly increase, we divide by 12:
Monthly rent increase = Increased tax amount / 12 = $27 / 12 = $2.25
Therefore, the monthly rent should be raised by $2.25 to absorb the increase in that year's taxes.
You have learned about special right triangles. Using that knowledge, you decide to take a square cake with 10-inch sides and divide it diagonally to form two special right triangles. Find and explain how you know the exact (no decimals) measure of the hypotenuse.
Now find the exact diagonal measure of cakes that are an 8-inch square, a 12-inch square, and a 15-inch square.
Did you discover a shortcut that works with any square cake? Explain.
Please show your work
The hypotenuse of a right triangle formed by dividing a square cake diagonally can be found using the Pythagorean Theorem, with the shortcut that the hypotenuse is the side length of the square multiplied by √2. Examples include a hypotenuse of 10√2 inches for a 10-inch square, 8√2 inches for an 8-inch square, 12√2 inches for a 12-inch square, and 15√2 inches for a 15-inch square.
Finding the Hypotenuse of Right Triangles in Squares
To find the length of the hypotenuse in a right triangle that is formed by dividing a square cake diagonally, we use the Pythagorean Theorem which states that for a right triangle with sides a and b and hypotenuse c, the relation is c = √(a ² + b ²). Since the sides of the square are equal in length, for a square with 10-inch sides, the hypotenuse will be √(10 inches ² + 10 inches ²) = √(100 + 100) = √200 inches = 10√2 inches.
For the other square cakes:
8-inch square: Hypotenuse = √(64 + 64) = 8√2 inches
12-inch square: Hypotenuse = √(144 + 144) = 12√2 inches
15-inch square: Hypotenuse = √(225 + 225) = 15√2 inches
The shortcut discovered is that the length of the hypotenuse is always the side length of the square multiplied by √2, because each side of the square forms a right triangle with equal sides when the square is divided diagonally.

Step-by-step explanation:
A bus traveled on a level road for 4 hours at an average speed of 20 miles per hour faster than it traveled on a winding road. The time spent on the winding road was 5 hours. Find the average speed on the level road if the entire trip was 449 miles.
To solve this problem, we must recall that the formula for velocity assuming linear motion:
v = d / t
Where,
v = velocity
d = distance
t = time
For condition 1: bus travelling on a level road
v1 = d1 / t1
(v2 + 20) = (449 – d2) / 4 --->1
For condition 2: bus travelling on a winding road
v2 = d2 / t2
v2 = d2 / 5 --->2
Combining equations 1 and 2:
(d2 / 5) + 20 = (449 – d2) / 4
0.8 d2 + 80 = 449 – d2
1.8 d2 = 369
d2 = 205 miles
Using equation 2, find for v2:
v2 = 205 / 5
v2 = 41 mph
Since v1 = v2 + 20
v1 = 41 + 20
v1 = 61 mph
Therefore the average speed on the level road is 61 mph.

The map of a biking trail is drawn on a coordinate grid. The trail starts at P(−3, 2) and goes to Q(1, 2). It continues from Q to R(1, −1) and then to S(8, −1). What is the total length (in units) of the biking trail?
Answer:
Total length of the biking trail is 14 units
Step-by-step explanation:
The trail starts from point P(-3, 2) and touches points Q(1, 2), R(1, -1) and S(8, -1).
We have to calculate the total length of the biking trail.
Since distance between two points are represented by
d = [tex]\sqrt{(x-x')^{2}+(y-y')^{2}}[/tex]
So length of PQ = [tex]\sqrt{(1+3)^{2}+(2-2)^{2}}[/tex]
PQ = [tex]\sqrt{(4)^{2}}[/tex]
PQ = 4 units
QR = [tex]\sqrt{(1-1)^{2}+(2+1)^{2}}[/tex]
QR = [tex]\sqrt{(3)^{2}}[/tex]
QR = 3 units
RS = [tex]\sqrt{(8-1)^{2}+(-1+1)^{2}}[/tex]
RS = [tex]\sqrt{(7)^{2}}[/tex]
RS = 7 units
Now total biking trail = PQ + QR + RS
= 4 + 3 + 7
= 14 units
Total length of the biking trail is 14 units
Answer:
The answer is 14 units

How many four-digit even numbers are possible if the leftmost digit cannot be zero
There are 4500 four-digit even numbers possible when the leftmost digit cannot be a zero.
Explanation:The question is about finding out the number of four-digit even numbers possible given that the first or leftmost digit cannot be a zero. In a four-digit even number, the last digit (rightmost) should be an even number, i.e., 0, 2, 4, 6, or 8. Hence, there are 5 possibilities for the last digit.
Next, since the leftmost digit cannot be a zero, it leaves us with 9 possibilities (1-9). Lastly, the middle two digits can be any digit from 0 to 9, so there are 10 possibilities each for the second and third digits.
Therefore, the total number of four-digit even numbers under the given conditions is found by multiplying these possibilities: 9 (for the first digit) * 10 (for the second digit) * 10 (for the third digit) * 5 (for the last digit) = 4500.

To find the number of four-digit even numbers where the leftmost digit cannot be zero, there are 9000 possibilities.
Explanation:To find the number of four-digit even numbers where the leftmost digit cannot be zero, we need to consider the following:
Choose the digit for the leftmost position (excluding zero). This can be done in 9 ways.Choose the digits for the other three positions (including zero for even numbers) in 10 ways each (0-9).By multiplying the number of choices for each position, we get the total number of four-digit even numbers without leading zeros: 9 * 10 * 10 * 10 = 9000.

The average number of field mice per acre in a 5-acre wheat field is estimated to be 12. find the probability that fewer than 7 field mice are found
The probability that fewer than 7 field mice are found in the 5-acre field is 0.0458.
The probability that fewer than 7 field mice are found in the entire 5-acre field is not simply 58.10% multiplied by 5. This is because the mice are not independent on each other. The number of mice on one acre doesn't affect the number found on another.
To find the probability for the entire field, we need to consider all possible combinations of the number of mice on each acre. This can be a complex calculation involving multiple Poisson distributions.
However, if we assume that the distribution of mice across the field is approximately uniform, we can use a simpler approach. We can assume that the probability of finding fewer than 7 mice on each acre is independent of the others and multiply the individual probabilities:
P(total < 7) ≈ (0.5810)^5 ≈ 0.0458
Therefore, under the assumption of approximate uniformity, the probability of finding fewer than 7 field mice in the entire 5-acre field is approximately 0.0458%.

Why does a calculator return an error when trying to find inverse sine of 1.055?
Answer:
1.055 is outside the domain of the sine function.
Step-by-step explanation:
When we are taking the inverse sine, we are finding an angle that gives a value of 1.055.
The sine function NEVER gives a value greater than 1 or less than -1. The domain of the sine function is between -1 and 1, inclusive.
So wanting to know which angle gives a sine value of 1.055 is futile. Sine can never be greater than 1.
That's why the calculator gives an error, because 1.055 is outside the domain of the sine function.
