AABC is similar to AGED with a scale factor of 22.5/48, which means that the width of the cart is proportional to the height, with a ratio of 30:22.5.
Since AABC and Matured are comparative, their relating points are equivalent, and their comparing sides are corresponding.
By definition, point An in AABC is equivalent to point An in Matured, as they are both right points. Likewise, point E in Matured is equivalent to point C in AABC, as they are both vertical points. At long last, point B in AABC is equivalent to point D in Matured, as they are both correlative points to point An and E, separately.
To demonstrate the sides are relative, we can utilize the proportions of comparing sides:
Stomach muscle/AG = BC/ED = AC/Promotion
Subbing the given qualities, we get:
Stomach muscle/48 = BC/36 = AC/x
where x is the length of the truck.
Tackling for x, we get:
x = AC * 36/BC
x = 30 * 36/48
x = 22.5 inches
In this way, AABC is like Matured with a scale variable of 22.5/48, and that implies that the width of the truck is relative to the level, with a proportion of 30:22.5.

A student is making a model of the Great Pyramid of Giza for the school arts festival. The edge length of the right square pyramid is 1.6 meters and its height is 2.4 meters. If the pyramid is to be painted with paint costing $8 per square meter, then, approximately what is the cost of painting the entire surface area of the pyramid, including its square base?.
The cost of painting the entire surface area of the pyramid, including its square base, is approximately $85.44.
What is the cost of painting?
The Great Pyramid of Giza has a square base, so the surface area of the base is simply the area of a square with side length 1.6 meters:
Area of base = (1.6 m)² = 2.56 m²
To find the surface area of the rest of the pyramid, we need to find the area of each of the four triangular faces. Each face is a right triangle with one leg equal to the slant height of the pyramid (which we can find using the Pythagorean theorem) and the other leg equal to half the length of one side of the base.
The slant height can be found using the Pythagorean theorem:
slant height = √((height)² + (1/2 × base)²)
slant height = √((2.4)² + (0.8)²) ≈ 2.53 meters
Then, the area of one triangular face is:
Area of triangular face = (1/2)baseheight
Area of triangular face = (1/2)(1.6 m)(2.53 m) ≈ 2.03 m²
Since there are four triangular faces, the total surface area of the pyramid is:
Total surface area = 4 × (Area of triangular face) + (Area of base)
Total surface area = 4 × (2.03 m²) + 2.56 m²
Total surface area ≈ 10.68 m²
Therefore, the cost of painting the entire surface area of the pyramid at a rate of $8 per square meter is approximately:
Cost = Total surface area × Cost per m²
Cost = 10.68 m² × $8/m²
Cost ≈ $85.44
So, the cost of painting the entire surface area of the pyramid, including its square base, is approximately $85.44.

Maricopa's Success scholarship fund receives a gift of $ 95000. The money is invested in stocks, bonds, and CDs. CDs pay 4.75 % interest, bonds pay 4.2 % interest, and stocks pay 11.2 % interest. Maricopa Success invests $ 35000 more in bonds than in CDs. If the annual income from the investments is $ 6845 , how much was invested in each account?
Answer:
$15000 was invested in CDs, $50000 was invested in bonds, and $30000 was invested in stocks.
Step-by-step explanation:
Let x be the amount invested in CDs. Then, the amount invested in bonds is x + 35000. The remaining amount invested in stocks is 95000 - (x + x + 35000) = 25000 - x.
The annual income from CDs is 0.0475x dollars. The annual income from bonds is 0.042(x + 35000) dollars. The annual income from stocks is 0.112(25000 - x) dollars.
The total annual income from all three investments is $6845: 0.0475x + 0.042(x + 35000) + 0.112(25000 - x) = 6845
Solving for x gives: x = $15000
Therefore, $15000 was invested in CDs, $50000 was invested in bonds, and $30000 was invested in stocks.

During the first couple weeks of a new flu outbreak, the disease spreads according to the equation I(t) = 3900e^0.0514, where I(t) is the number of infected people t days after the outbreak was first identified. Find the rate at which the infected population is growing after 8 days and select the appropriate units.
The rate at which the infected population is growing after 8 days of the outbreak is approximately 1096.57 people per day, as determined by the derivative of the given function with respect to time.
To find the rate at which the infected population is growing after 8 days, we need to take the derivative of the given function I(t) with respect to t:
[tex]dI/dt = 3900(0.0514)e^(0.0514t)[/tex]
At t=8, the rate at which the infected population is growing is:
[tex]dI/dt = 3900(0.0514)e^(0.0514*8) = 1096.57[/tex]
Therefore, the rate at which the infected population is growing after 8 days is approximately 1096.57 people per day.
It is important to note that this rate of growth is an instantaneous rate at t=8, and it will likely change as time passes and the outbreak progresses. Furthermore, the rate of growth of the infected population depends on various factors such as the transmission rate of the virus, the effectiveness of preventive measures, and the availability of healthcare resources.
In conclusion, the rate at which the infected population is growing after 8 days of the outbreak is approximately 1096.57 people per day, as determined by the derivative of the given function with respect to time. This result provides insight into the early stages of a flu outbreak, but further analysis is required to understand the longer-term dynamics of the outbreak and the factors that affect the spread of the disease.

Rewrite each explicit formula in function form.
g n= − 3 · (1_2)n − 1g
and
n= 4 · (1_3)n − 1
Rewriting each explicit formula in function form given below:
[tex]g(n) = -3 * (1/2)^(^n^-^1^)[/tex]
[tex]f(n) = 4 * (1/3)^(^n^-^1^)[/tex]
How to solveTo convert an explicit formula into a function form, one must denote the variable 'n' as its respective input and represent the formula with that of a function.
Listed below are the steps required:
Original formulas:
[tex]g n = -3.(1_2)n- 1g[/tex]
[tex]n = 4.(1_3)n-1[/tex]
In order to transform the original expression to function format, follow these instructions for each individual formula:
- Step 1: Establish both the name of the function and the input parameter it accepts, denoted respectively by 'g', or 'n'.
- Step 2: Alter the specified representation; replace "g n" with "g(n)".
- Step 3: Substitute the hyphen sign '_' with a division symbol '/'.
Subsequently, applying this method specifically on equation g n = -3 * (1_2)n - 1g generates:
[tex]g(n) = -3 * (1/2)^(^n^-^1^)[/tex]
Thus, the rewritten version in function format is displayed as priorly referred:
[tex]g(n) = -3 * (1/2)^(^n^-^1^)[/tex]
To implement the same procedure on another given formula, where it states n = 4 * (1_3)n - 1:
- Step 1: Uncover the variables' identity with regards to the name of the function and the current parameters utilized, therefore establishing a new function label 'f' while preserving the relative input, just like previously conducted during the initial steps.
- Step 2: Adapt your notation appropriately utilizing the newly established variables mentioned in Step 1.
- Step 3: Substitute the underscore designation '*' present within the term with a forward slash '/'.
As a result, following the process will create the convenient formulation of the certain algebraic formula as f(n) = [tex]4 * (1/3)^(^n^-^1^).[/tex]
Thus, the final draft written in functional form is presented as:
[tex]f(n) = 4 * (1/3)^(^n^-^1^)[/tex]

A vegetable has six carrot sticks four celery sticks five tomatoes and three pieces of cauliflower. in how many different orders could we eat all the vegetables?
Answer:
There are 18 total pieces of vegetables, so there are 18 possible choices for the first piece, 17 possible choices for the second piece, 16 possible choices for the third piece, and so on, until there is only 1 possible choice for the last piece. Therefore, the total number of different orders we could eat all the vegetables is:
18 x 17 x 16 x 15 x 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

20ft flag pole has a rope tied from to top to the ground. The rope makes a 35° angle with the ground. How long is the rope?
the length of the rope is approximately 11.9 feet.
What is right angle triangle?
The term "right-angled triangle" refers to any triangle with an internal angle that is either a right angle or 90 degrees in value. The right triangle or the 90-degree triangle are other names for this triangle because of this. Right triangles have "opposite" and "adjacent" sides, which refer to the sides that are across from and next to respective angles, respectively. When a right triangle is formed, the hypotenuse is its longest side.
We can consider the flagpole, the ground, and the rope as forming a right triangle. The angle between the flagpole and the rope is 90 degrees, and the angle between the rope and the ground is 35 degrees. Therefore, the angle between the flagpole and the ground is 90 - 35 = 55 degrees.
Let's call the length of the rope "r". We can use the trigonometric function tangent to find r:
tan(35°) = opposite/adjacent = r/20
Multiplying both sides by 20, we get:
r = 20 tan(35°)
Using a calculator, we get:
r ≈ 11.9 feet
Therefore, the length of the rope is approximately 11.9 feet.

Where else would the sample size be?For the 100 m race with Mark Chase and Beatrice, the sample space of all the possible ways in which the three runners can win first, second, and third place is:
{M-C-B, M-B-C, C-M-B, C-B-M, B-M-C, B-C-M}
where M stands for Mark, C stands for Chase, and B stands for Beatrice. We have six possible permutations because there are three choices for the first place, two choices for the second place (as one person has already won first place), and one choice left for the third place.
If there were four runners and three positions to be won, the sample space would be:
{A-B-C-D, A-B-D-C, A-C-B-D, A-C-D-B, A-D-B-C, A-D-C-B, B-A-C-D, B-A-D-C, B-C-A-D, B-C-D-A, B-D-A-C, B-D-C-A, C-A-B-D, C-A-D-B, C-B-A-D, C-B-D-A, C-D-A-B, C-D-B-A, D-A-B-C, D-A-C-B, D-B-A-C, D-B-C-A, D-C-A-B, D-C-B-A}
where A, B, C, and D represent the four runners. We have 24 possible permutations because there are four choices for the first place, three choices for the second place (as two people have already won first and second place), and two choices for the third place (as three people have already won first, second, and third place).
Note that in both cases, we assume that all runners are equally skilled and have an equal chance of winning each position. In reality, there may be differences in skill levels, which would affect the probabilities of each possible outcome.
