Katrina owns a 9-acre farm. Last month, she bought her neighbor’s adjoining 8-acre farm. How large is Katrina’s farm now?

Answer:

33.61 ft

Step-by-step explanation:

First you find the product of 3ft and 8%

3.0(0.8)=2.4

Then you find the product of 2.4 and 14years

2.4(14)=33.61

Using the formula for exponential growth, a tree that is initially 3 feet tall and grows at a rate of 8% per year would be approximately 5.23 feet tall at the end of 14 years.

To solve this problem, we can use the formula for exponential growth: Final amount = Initial amount * (1 + Growth rate) ^ Number of periods.

The initial height of the tree is given as 3 feet. This is our initial amount. The growth rate is 8% per year, so we represent this as 0.08 in our formula. The number of periods is 14 years.

So, we have:

Final height = 3 * (1 + 0.08) ^ 14

To find the final height, we multiply 3 by 1.08 raised to the power of 14. Doing the math, the tree would be approximately 5.23 feet tall at the end of 14 years, rounded to the nearest hundredth.

Answer:

$3,450

Step-by-step explanation:

As Maria earns 15% commission, a car sale of $23,000 would lead to a $3,450 commission. This can be achieved by multiplying .15 (15% translated into a decimal) to the total car sale of $23,000.

x = commission

x = 23,000 * (.15) = 3,450

Final answer:

Maria would earn a commission of $3,450 on a sale of a car priced at $23,000, calculated by multiplying the sale amount by her 15% commission rate.

Explanation:

Maria earns a 15% commission on her car sales. If she sells a car for $23,000, her commission is calculated by multiplying the total sale amount by the commission rate. To find the commission, use the following formula:

Commission = Sale Amount × Commission Rate

Commission = $23,000 × 0.15

Commission = $3,450

Therefore, Maria would earn a commission of $3,450 on a sale of $23,000.

You can do it four ways for horizontal straight line using a ruler.

Step-by-step explanation:

i did was make a 2x2 grid, and then arrange the four pictures inside.

Final answer:

There are 24 different ways to arrange four pictures on a wall in a horizontal straight line, calculated using the factorial of the number of pictures (4!).

Explanation:

The question of how many different ways you can arrange four pictures on a wall if you want them in a horizontal straight line is a problem of permutations, which is a concept in mathematics. To determine the number of different arrangements, we calculate the factorial of the number of pictures. The factorial, represented by an exclamation mark (!), means that you multiply the number by every number below it down to 1. For four pictures, the calculation is 4! (which is 4 x 3 x 2 x 1).

The result is:

Therefore, there are 24 different ways to arrange four pictures on a wall in a horizontal straight line.

Answer:

468

Step-by-step explanation:

The volume of a cube is V = s³. Fin the volume of each cube separately and add together for the volume all together.

The small cube has side length 5 so V = 5³ = 125.

The large cube has side length 7 since 12 - 5 = 7. So V = 7³ = 343.

Together the volume is 125 + 343 = 468

Answer:

Step-by-step explanation:

The mean number of acres for each park for the two cities is:

City A: 7.5

City B: 7.3

Hence, It is Much greater for City A than for City B.

And, The range for the number of acres for parks for the two cities is : 8

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

The table shows the number of acres for each park in the two cities.

City A:  6   9   10   7   10   10   2   5   8   8

City B :  5   10   8   11    7    12   6   5   4   5

For City A:

Minimum acre of park = 2

Maximum acre of park = 10

Hence, Range = Maximum-Minimum

Range = 10-2

Range = 8

Now mean is calculated as:

Mean = 6 + 9 + 10 + 7 + 10 + 10 + 2 + 5 + 8 + 8 / 10

          = 75/10

          = 7.5

For City B:

Minimum acre of park = 4

Maximum acre of park = 12

Hence, Range = Maximum-Minimum

Range = 12-4

Range = 8

Now mean is calculated as:

Mean = 5 + 10 + 8 + 11 + 7 + 12+ 6 + 5+ 4 + 5 / 10

         = 73/10

         = 7.3

Hence, The mean number of acres for each park for the two cities is:

City A: 7.5

City B: 7.3

Hence, It is Much greater for City A than for City B.

And, The range for the number of acres for parks for the two cities is : 8

Answer:

[tex]\frac{x}{4}-\frac{111}{4}\\x=2y+7[/tex]

I'm pretty sure this is correct!

Answer:

(- 97, - 52)

Step-by-step explanation:

given the 2 equations

x - 4y = 111 → (1)

2y - x = - 7 → (2)

Rearrange (1) expressing x in terms of y by adding 4y to both sides

x = 111 + 4y → (3)

Substitute x = 111 + 4y into (2)

2y - (111 + 4y ) = - 7 ← distribute and simplify left side

2y - 111 - 4y = - 7

- 2y - 111 = - 7 ( add 111 to both sides )

- 2y = 104 ( divide both sides by - 2 )

y = - 52

Substitute y = - 52 into (3) for corresponding value of x

x = 111 + 4(- 52) = 111 - 208 = -97

Solution is ( - 97, - 52 )

Step-by-step explanation:

The inequality is determined by examining the graph, identifying the lines, their slopes and determining if they are increasing or decreasing. Positive slopes are for increasing lines and negative slopes are for decreasing lines. Inequalities should represent the identified lines and their slopes.

From your question, it seems that there's a graph involved depicting certain lines and you're supposed to choose an inequality that represents the graph. As per the given information that line A is decreasing and line B is increasing, it sounds like these lines may represent an inequality on the coordinate plane. Consider the slope of line A and line B. If one is steeper than the other, the steeper slope has a larger absolute value. An increasing line indicates a positive slope, while a decreasing line indicates a negative slope. For example, if line A is y < -2x + 3 (negative slope, line decreasing) and line B is [tex]y > 5x + 1[/tex](positive slope, line increasing), the inequality would be [tex]y > 5x + 1 - y < -2x + 3.[/tex]For a precise and correct answer, you need to analyze the graph, identify lines, intercepts, slopes, and shading to form the correct inequality.

Answer:

2(x-4) = 5

Step-by-step explanation:

2(x-4) = 5 since the difference of a number and 4 translates to x-4 and twice the difference translates to 2(x-4).

The required equation is, 2(x-4) = 5

It is a mathematical statement which contains two algebraic expressions on both sides of an ' = ' sign.

Equation shows the equality between the expressions in left hand and right hand side.

According to the problem, the variable for the unknown number = x

Now we have to establish the equation.

Difference between x & 4 = (x-4)

Twice the difference between x & 4 = 2(x-4)

Twice the difference between x & 4 is equals to 5.

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

Number of students asked in a survey = 60

Number of students who play an instrument = 35

Number of students who are in band = 30

Number of students who are not in band = 30

So, the two way frequency table would be :

                                          Play instrument     Not play instrument    Total

In band                                       30                             0                           30

Not in band                                  5                             25                          30

The slope of the given linear line is 3/5 thus the equation is y = 3/5 x so option (A) is correct.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given,

The slope of the line is 3/5

Since, the equation is y = mx + c where m is the slope and c is the y-intercept.

In the given line c = 0 and m = 3/5

y = 3/5 x

Hence "The slope of the given linear line is 3/5 thus the equation is y = 3/5 x".
