Step-by-step explanation:

From the given diagram we notice that

1. Line AB is equal to Line DE.

2. Line AC is equal to line DF.

3. Angle A is equal to angle D

Then, it shows that 2 sides of the triangle are similar and 1 of it's angle is also similar. Then, it is SAS

Where, S- represent sides and A- represents angle

NOTE : we have SSS, ASA, AAS and SAS, we don't have SSA

To write the similar triangle equation

∆ABC ≈ ∆DEF

Since AB is equal to DE, the we replace It with DE and also Angle A is equal to angle D. Also AC is equal to DF, then we replace C with F.

So the answer is C

∆ABC ≈ ∆DEF SAS

Answer:

$2 per ride

Step-by-step explanation:

$32-$20=$12

McKenna rode 6 rides so $12 divided by 6 rides is $2 for every ride

Final answer:

The equation to find the price for each ride McKenna paid at the carnival is $32 - 6P = $20. Solving for P gives us P = $2, so each ride costs $2.

Explanation:

To find the price for each ride that McKenna paid at the carnival, we need to set up an equation based on the information given. McKenna started with $32 and ended with $20 after riding 6 rides. The amount spent on rides is the difference between the starting amount and the remaining amount.

The equation will be:

Initial amount - (Price per ride × Number of rides) = Remaining amount

$32 - (Price per ride × 6) = $20

Let's denote the price for each ride as P. So the equation becomes:

$32 - 6P = $20

To solve for P, we rearrange the equation:

6P = $32 - $20

6P = $12

P = $12 / 6

P = $2

Hence, the price for each ride is $2.

Answer: radius=8, circumference=16π

Step-by-step explanation:

diameter is 16 centimeters

the radius of a circle is half its diameter

so, radius = 16/2 = 8

circumference of a circle = 2πr

so, circumference = 2π(8cm) = (16π) cm

Answer:

$0.10x + $0.25y = $0.80

The equation in standard form that represents the situation is 10x + 25y = 80.

To represent the situation in terms of the number of dimes and quarters, we can use the equation 0.10x + 0.25y = 0.80. This equation states that the value of the dimes (0.10x) plus the value of the quarters (0.25y) equals $0.80. Rearranging the equation to standard form, we have:

0.10x + 0.25y = 0.80

10x + 25y = 80

So, the equation in standard form that represents the situation is 10x + 25y = 80.

Answer:

The company's profit be in the year 2008 is $8.3 million.

Step-by-step explanation:

Given:

In the year 2006, a company made $7 million in profit, their profit increased by 9%.

So, we need to calculate the company's profit be in the year 2008.

Now, by putting the formula to find the profit(P) after the two year:

Difference between the year = 2008 - 2006 = 2 year.

So, number of years(n) = 2 year

Rate of profit increasing(r) = 9%

Amount company made in 2006 (A) = $7 million.

[tex]P=A(1+\frac{r}{100})^{n}[/tex]

[tex]P=7(1+\frac{9}{100})^{2}[/tex]

[tex]P=7(1+0.09)^{2}[/tex]

[tex]P=7(1.09)^{2}[/tex]

[tex]P=7\times 1.188[/tex]

[tex]P=8.316[/tex]

Profit in the year 2008 would be 8.316 million, and nearest to the tenth of a million dollars is $8.3 as 3 is in the tenth place of the decimal and 1 in the hundredth so rounding will change $8.316 to $8.3.

Therefore, the company's profit be in the year 2008 is $8.3 million.

Final answer:

To find the company's profit in 2008 after a 9% increase each year from 2006, we calculate compound growth over two years. The profit in 2008 would be $8,316,700, which rounds to $8.3 million.

Explanation:

To calculate the company's profit in the year 2008 after it increased by 9% each year following 2006, we can use the formula for compound interest which is similar to calculating compounded profit growth. The formula is:

[tex]P = P_0 \times (1 + r)^t[/tex]

Where:

P is the future profit

P₀ is the initial profit ($7 million)

r is the annual growth rate (9% or 0.09)

t is the number of years since 2006 (2008 - 2006 = 2 years)

Let's calculate the profit for 2008:

P = $7,000,000 × (1 + 0.09)²

First, calculate the growth factor for one year:

1 + 0.09 = 1.09

Now, apply the growth factor for two years:

1.09² = 1.1881

Multiply the initial profit by the growth factor:

P = $7,000,000 × 1.1881 = $8,316,700

To the nearest tenth of a million dollars, the company's profit in 2008 would be $8.3 million.

Answer:

5x + y - 4 = 0

Step-by-step explanation:

When we are given two points and are asked to find the equation of the line we use the two - point form.

Two - point form: [tex]$ \frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 - x_1} $[/tex].

where: [tex]$ (x_1,y_1) $[/tex] and [tex]$ (x_2,y_2) $[/tex] are the two points on the line.

Given the two points are: (5,21) and (-5,-29).

Substituting in the two point form:

⇒  [tex]$ \frac{y - 21}{-29 - 21} = \frac{x - 5}{-5 -5} $[/tex]

Final answer:

Three half squared is (3/2)², which equals 9/4 when you square the numerator (3² = 9) and the denominator (2² = 4) separately.

Explanation:

The expression 'three half squared' refers to the quantity (3/2) squared. To square a fraction, you square the numerator and the denominator separately. Therefore, (3/2) squared is (3 squared) over (2 squared), which is 9 over 4. Since there are no further simplifications to make, 9/4 is the final answer as a fraction.

To understand this conceptually, think about the process of squaring as finding the area of a square with side lengths of the original number. So, if the side length of a square is 3/2, the area (which represents the square of the number) will be 9/4 square units.

Final answer:

To determine what three-half squared is as a fraction, you simply square the numerator and denominator separately, arriving at the fraction 9/4.

Explanation:

Calculating Three-Half Squared as a Fraction

To find what three half squared is as a fraction, you square both the numerator and the denominator of the fraction 3/2. When you square the numerator (3), you get 9, and when you square the denominator (2), you get 4. Therefore, the answer to three half squared is 9/4, as we have calculated (3/2)² = (3²)/(2²) = 9/4.

This calculation is similar to understanding that if you start with half of a pie and you multiply this amount by itself, you are essentially getting a fraction of the original whole. In our example, by squaring half, we get a quarter, thereby following the intuitive sense of fractions.

Final answer:

The point estimate for the proportion of homeowners in the given sample is 75%, calculated by dividing the number of homeowners (24) by the total number surveyed (32).

Explanation:

To obtain a point estimate of the proportion of homeowners from the given sample, we would calculate the proportion of those who did not rent, since owning and renting are the only two options provided. Out of 32 people, 8 said they rented, which means 32 - 8 = 24 owned their home. The point estimate for the proportion of homeowners is then given by the number of homeowners divided by the total number of people surveyed:

Point estimate for homeowners = (Number of homeowners) / (Total number surveyed) = 24 / 32 = 0.75 or 75%

This mean 75% of the surveyed individuals are estimated to be homeowners.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

-5x+3y=51 ..........(1)

y=10x-8 .............(2)

Put the value of y from equation (2) in equation (1) we get

-5x+ 3(10x - 8)= 51

-5x + 30x - 24 = 51

25x = 51+ 24

25x = 75

x= 3

Answer:

2.5%

Step-by-step explanation:

The price increased from 2 to 2.05. So the increase was:

2.05 - 2 = 0.05 dollars

Now, to find percentage increase, we use the formula below:

[tex]\frac{New-Old}{Old}*100[/tex]

Where

New is the latest price (here it is the increased price of 2.05)

Old is the previous price (here it is the less price of 2.00)

Now, we substitute and find:

[tex]\frac{2.05-2.00}{2.00}*100=2.5[/tex]

So the price increase was 2.5%

To find the alcohol percentage in the 4:1 ratio, we use the information from the 3:2 ratio. For every 3 parts alcohol, there are 2 parts water. When mixed at a ratio of 4:1, the alcohol percentage is 24%.

Explanation:

To determine the alcohol percentage of the solution when mixed at a ratio of 4:1, we can use the information given in the question. When mixed at a ratio of 3:2, the solution contains 18% alcohol. This means that for every 3 parts alcohol, there are 2 parts water. We can use this information to find the alcohol percentage for the 4:1 ratio.

Let's say we have 4 mL of alcohol and 1 mL of water. The total volume is 4+1 = 5 mL. In the 3:2 ratio, the alcohol percentage is 18%. So, for 3 mL of alcohol, the total volume is 3+2 = 5 mL. Therefore, the alcohol percentage for the 4:1 ratio is (18/3) * 4 = 24%.

To find the total price including tax after a meal at a restaurant, convert the tax rate to a decimal, then multiply it by the total cost and add the result to the original total cost.

First, find the amount of sales tax. To do this, convert the percent to a decimal by dividing by 100: 8.25% = 0.0825.

Then multiply the total cost by the decimal tax rate to get the tax amount. In this case, $95 * 0.0825 = $7.8375.

Next, add the tax amount to the original total cost to find the total price: $95 (original cost) + $7.8375 (tax) = $102.8375.

Therefore, the total price, including tax, for Shirley and her family's meal last night was $102.84.

Vertex-edge graphs can model real-world problems, not all graphs can be solved, Euler paths and Hamilton paths are different, and in a Hamilton circuit, all vertices must be used exactly once.

Explanation:

Vertex-edge graphs, also known as graphs or networks, are mathematical structures that consist of vertices (also called nodes) connected by edges. They are widely used to model real-world problems across various fields such as computer science, transportation planning, and social networks, among others (1). While some vertex-edge graphs can be solved, it is not true that all graphs can be solved. Solvability depends on the specific problem being represented by the graph and the algorithms or methods used to solve it (2). Euler paths and Hamilton paths are not the same. An Euler path is a path in a graph that visits every edge exactly once, while a Hamilton path visits every vertex exactly once (3). In a Hamilton circuit, all vertices must be used exactly once, but not in a Hamilton path. There can be more than one Hamilton path in a graph, depending on its structure (4).
