Use the Pythagorean theorem: a² + b² = c²

9 ft² + h² = 144 ft²

h² = 135 ft²

h = √(135 ft²)

h = 11.6 ft

a) The assessed value of the residential property is, proportionately, $45,806.

b) Proportionately, the market value of the property is $111,722.

Proportion refers to two ratios equated to each other.

Proportion is a fractional value, expressed as the relative size of a variable or number to another.

We represent proportions as decimals, fractions, or percentages.

The assessed value of a residential property = 41% of the market value

Residential property tax rate = 3³/₅% or 3.6% of the assessed value

Tax = $1,649

Assessed value = $45,806 ($1,649/3.6%)

Market value = $111,722 ($45,806/41%)

The cosine of the angle opposite the side of length 5.64 meters is 0.4536.

In a triangle, the cosine of the angle opposite a side is given by the formula:

cos(angle) = (a^2 + b^2 - c^2)/(2ab) where a, b, and c are the lengths of the sides of the triangle and angle is the angle opposite the side of length c. Given the side lengths of the triangle as 3.18 meters, 7.82 meters and 5.64 meters, the side opposite angle we want to find is 5.64 meters.

so we can use the above formula and substitute the values,

cos(angle) = (3.18^2 + 7.82^2 - 5.64^2)/(23.187.82) = 0.4536

Answer:

If 55% of the fish in the pond are goldfish, that would be 55/100 of the total number of fish. To express this as a fraction in its simplest form, we would divide the numerator and denominator by the greatest common divisor, 5. So, 55/100 simplifies to 11/20.

10/3 of the fish in the pond are perch, which in its simplest form is already in the form of 10/3.

The rest of the fish are sticklebacks, meaning the total number of goldfish, perch, and sticklebacks must add up to 100%. Therefore, to find the ratio of sticklebacks to goldfish and perch, we can subtract the percentage of goldfish and perch from 100%.

100 - 55 - (10/3) = 100 - 55 - 10/3 = 100 - 55 - (10/3) = 100 - 55 - (10*3/3) = 100 - 55 - 10 = 35.

So the ratio of goldfish to perch to sticklebacks in this pond is 11/20: 10/3: 35/100 in its simplest form.

The result of the calculation, 120, will be stored in register r7.

Factorial is a mathematical operation where a number is multiplied by all its preceding numbers until 1. For example, 5! is calculated by multiplying 5 by 4, then 4 by 3, then 3 by 2, then 2 by 1. In mathematical notation, this is expressed as:

5! = 5 * 4 * 3 * 2 * 1

= 120

In arm assembly language, we can create a loop that multiplies the number that is stored in register r0 with all of its preceding numbers until 1 is reached. The result of the calculation will be stored in register r7. For example, to calculate 5!, we can set the initial value of r0 to 5 and the initial value of r7 to 1. Then, we can create a loop that multiplies the value of r0 by the value of r7 and then decrements the value of r0. This loop will run until r0 is equal to 1. At that point, the loop will end and the result of the calculation will be stored in r7. The following example shows the code for a program to calculate 5!:

MOV R0, #5

MOV R7, #1

MUL R7, R0

a. Equation for Bert to figure out Ernie's original number is x = 5(2x - 6) + (-6).

b. Ernie's original number/integer was 4.

c. On checking and verifying the original integer is obtained as 4.

What is integers?

The Latin term "Integer," which implies entire or intact, is where the word "integer" first appeared. Zero, positive numbers, and negative numbers make up the particular set of numbers known as integers.

Ernie picks an integer from 1 to 10.

Let the value of the integer be x.

First the number is doubled, so the value of integer becomes = 2x.

Then 6 is subtracted from the number, so the value of integer becomes = 2x - 6.

Then the entire difference is multiplied by 5, so the value of integer becomes = 5(2x - 6).

Lastly -6 is added to the product, so the value of integer becomes = 5(2x - 6) + (-6).

So, the equation to find the integer is -

x = 5(2x - 6) + (-6)

Now, simplify this expression to obtain the number.

x = 5(2x - 6) + (-6)

x = 10x - 30 - 6

x - 10x = -36

-9x = -36

x = -36/-9

x = 4

Check if 4 is the correct number -

First the number is doubled = 4 × 2 = 8

Subtract 6 from the number = 8 - 6 = 2

Then multiply the difference by 5 = 5 × 2 = 10

Then subtract -6 from the number = 10 - 6 = 4

Therefore, the original number was 4.

We have 50 cases to distribute among 8 varieties of dairy products, with a restriction of 20 cases of milk.

To find the total number of ways to place the order, you can use the binomial coefficient formula, which is often used in combinatorics to count the number of ways to choose k items from a set of n items without regard to order. In this case, you have 8 varieties of dairy products and you want to choose 50 cases in total, with no regard to the order in which you choose the cases. So, the number of ways to place the order is:

(n k) = (8 50) = 8! / (50! (8-50)!) = 8! / (50! (-42)!) = 8! / 50! = 87654321 / (50494847464544434241)

This is a very large number, and it's impractical to calculate it exactly.

To find the number of ways to place the order if they order at most 20 cases of milk, you can use a similar approach, but with a restriction on the number of cases of milk. One way to do this is to use the stars and bars method, which is a combinatorial method for counting the number of ways to distribute n identical items into k distinguishable containers, with a restriction on the number of items in some of the containers.

In this case, we have 50 cases to distribute among 8 varieties of dairy products, with a restriction of 20 cases of milk. So, the number of ways to place the order is:

(50 + 8 - 1) choose (8 - 1) = 56 choose 7 = 56! / (7! 49!) = 56555453525150 / (7654321) = 807,794,400

The distance covered by the particle or the body in an hour is called the average speed. It is a scalar quantity. It is the ratio of the total distance to the total time.

We know that the average speed formula is given as,

Average speed = Total distance / Total time

Brice is taking a bike tour of the city. The entire tour is 24 ⁷/₁₀ kilometers long. Brice knows that his average biking rate is 4.3 meters per second.

Convert the mixed fraction number to a decimal number. Then we have

24 ⁷/₁₀ = 24 + 0.70

24 ⁷/₁₀ = 24.70 kilometers

Convert the speed into kilometers per hour. Then we have

Speed = 4.3 x 18/5

Speed = 15.48 kilometers per hour

Then the total number of hours for the trip is given as,

15.48 = 24.70 / T

T = 24.70 / 15.48

The slope of the line is -20

The slope of a line is a measure of how steep the line is. It is defined as the ratio of the change in the y-coordinate (rise) to the change in the x-coordinate (run) between two points on the line. The formula for the slope of a line is:

m = (y2 - y1) / (x2 - x1)

Where (x1, y1) and (x2, y2) are the coordinates of two distinct points on the line.

From the graph, you can pick any two points. That is:

x1 = 0, y1 = 120 and x2 = 4, y2 = 40

m = (y2 - y1) / (x2 - x1)

m = (40- 120) / (4 - 0)

m = -80/4
