Anna is trying to find the length of segment AC. Which equation could she use? A) AC = 2 + 7 B) AC2 = 42 + 12 C) AC2 = 22 + 72 D) AC2 = 72 − 22

Answer:

$9,830.40

Step-by-step explanation:

1st year--$30,000.00 x .20=$6,000.00= $30,000.00 - $6,000.00 =$24,000.00

2nd year--$24,000.00 x .20=$4 800.00=$24,000.00 -$4,800.00=$19 200.00

3rd year---$19,200.00 x .20 =$3,840.00= $19,200.00 - $3,840.00 = $15,360.00

4th year---$15,360.00 x .20=$3,072.00=$15,360.00 - $3,072.00=$12,288.00

5th year $12,288.00 x .20=$2,457.60=$12,288.00 - $2,457.60 =$9,830.40

Answer: FIrst option, Fourth option and Fifth option.

Step-by-step explanation:

First it is important to know the definition of "Dilation".

A Dilation is defined as a transformation in which the Image (which is the figure obtained after the transformation) and the Pre-Image (this is the original figure, before the transformations) have the same shape, but their sizes are different.

If the length of CD is dilated with a scale factor of "n" and it is centered at the origin, the length C'D' will be:

[tex]C'D'=nCD=(n)(12\ units)[/tex]

Therefore, knowing this, you can determine that:

1. If [tex]n=\frac{3}{2}[/tex] , you get:

[tex]C'D'=(\frac{3}{2})(12\ units)=18\ units[/tex]

2. If [tex]n=4[/tex], then the length of C'D' is:

[tex]C'D'=(4)(12\ units)=48\ units[/tex]

3. If [tex]n=8[/tex], then:

[tex]C'D'=(8)(12\ units)=96\ units[/tex]

4. If [tex]n=2[/tex], then, you get that the lenght of C'D' is:

[tex]C'D'=(2)(12\ units)=24\ units[/tex]

5. If [tex]n=\frac{3}{4}[/tex], the length of C'D' is the following:

[tex]C'D'=(\frac{3}{4})(12\ units)=9\ units[/tex]

Answer:

True

Step-by-step explanation:

A ratio is a numerical comparison broken down to its most simplest form. Theoretically, a ratio can be the same as a percentage.

45% is the same as 45/100. It can be simplified by dividing 5 from it to get 9/20...

which is the same as the 9:20 ratio.

Hope this helps!

Hope this

Final answer:

The statement is true; A being 45% of B is the same as the ratio A:B being 9:20, since 45% can be expressed as the fraction 9/20.

Explanation:

The statement that if A is 45% of B, then the ratio A:B is 9:20 is true. To understand this, we consider that 45% can be written as a fraction, which is 45/100 or simplified to 9/20.

Using the definition of percentage as a ratio that compares numbers with a denominator of 100, we can translate 45% into a fraction or ratio. This makes A/B = 9/20. Hence, expressing A as a percentage of B (A is 45% of B) is the same as writing the ratio of A to B as 9 to 20.

A practical example can illustrate this further. If B were $100, then 45% of $100 is $45, meaning A would be $45. Thus, A:B would be $45:$100, which simplifies down to 9:20 when considering their fractional equivalents.

Answer:

12a + 24 = 6(2a + 4) is the equivalent expressions

Step-by-step explanation:

Given the terms ; 4, 12a, 6, 2a, and 24

There are two terms with unknown = 12a and 2a

but 12a = 2a x 6 .........(1)

from the last term = 24 = 6 x 4 ...........(2)

add both equation 1 and 2 = 12a + 24

12a + 24 = 6(2a + 4) is the equivalent expressions .

to VERIFY; Use a = 2

substitute into the expression ; LHS = RHS

= 12(2) + 24 = 24 + 24 = 48 (LHS)

FOR RHS = 6(2a+4) = 6(2x2 + 4)

= 6(4+4) = 48

Hence LHS = RHS

Answer:

90

Step-by-step explanation:

"The answer is 90.

To round 86 to the nearest ten, one must look at the digit in the ones place, which is 6 in this case. Since 6 is greater than or equal to 5, the number in the tens place is increased by one. The digit in the tens place is 8, so when it is increased by one, it becomes 9. Therefore, 86 rounded to the nearest ten is 90."

Well, first off, any ameteur who read the question once would know he is INCORRECT, this is because you can easily see he's dividing it by 3 not 6 like you should be, so 2.99 divided by 6 is 0.498333 ( continuing ) so since this must be rounded to the nearest hundredth, so, 50 cents per bottle.

So question 1: No, because he divided with the incorrect numbers.

Question 2:( I actually don't understand this question, cause we just established he was wrong ) so since I don't understand this one, imma say no, or meh.

The future value of a condominium bought for $145,000 with a 5% annual appreciation over 5 years is calculated using the compound interest formula, resulting in a value of approximately $185,061.

The question is asking us to calculate the future value of an investment in real estate, specifically a condominium that was bought for $145,000 with an annual appreciation rate of 5% over a span of 5 years. To find the value of the condo in 5 years, we use the formula for compound interest, which is:

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

Where:

A is the amount of money accumulated after n years, including interest.

P is the principal amount (the initial amount of money).

r is the annual interest rate (decimal).

n is the number of times that interest is compounded per year.

t is the time the money is invested for in years.

Since the appreciation is compounded annually, n is 1. So, we can simplify the formula to:

[tex]A = P(1 + r)^t[/tex]

Substituting the given values:

[tex]A = $145,000(1 + 0.05)^5[/tex]

Now, let's calculate the future value:

[tex]A = $145,000(1.05)^5[/tex]

A = $145,000(1.2762825)

A ≈ $185,061

The condominium will be worth approximately $185,061 in 5 years.

Eighteen less than the quotient of twelve and a number is written as:

[tex]\frac{12}{x} - 18[/tex]

Solution:

Given statement is:

Eighteen less than the quotient of twelve and a number

We have to translate the given sentence into algebraic expression

Let "x" be the number

Therefore,

Eighteen less than the quotient of twelve and "x"

Quotient means result of division

Therefore,

[tex]\frac{12}{x} - 18[/tex]

Which means, 18 less than quotient of 12 and x

Thus the given sentence is translated into algebraic expression

The phrase 'eighteen less than the quotient of twelve and a number' is mathematically expressed as 12/n - 18, where n represents the unknown number.

The expression 'eighteen less than the quotient of twelve and a number' translates to a mathematical operation. First, we find the quotient of twelve and a number, which is the result of dividing twelve by that number (let's call it n). Then, we subtract eighteen from that quotient. The algebraic representation of this expression is 12/n - 18.

It's important to follow mathematical rules and order of operations correctly when performing such calculations, similarly to how the rules of arithmetic must be applied correctly regardless of the context, as is described in the example of counting goats or students. Mathematics provides various methods to arrive at the correct answer, and in this case, simplifying the operation is straightforward. It is a demonstration of understanding the correct usage of mathematical operations as well as number fluency.

25. transversal line

Check the picture below.

Based on a sample of 60 students, where 8 have more than 3 siblings, approximately 112 students out of 840 at Showton Middle School are estimated to have more than 3 siblings.

If there are 840 students at the school, we can use this sample to estimate the total number of students likely to have more than 3 siblings across the entire school population. This is a problem related to proportions within a population.

To make this estimation, we need to set up a proportion based on the sample data:

Now we can set up a proportion:

(number of students with >3 siblings) / 840 = 8 / 60

We solve for the unknown number of students with more than 3 siblings by cross-multiplying:

(number of students with >3 siblings) * 60 = 8 * 840

(number of students with >3 siblings) = (8 * 840) / 60

(number of students with >3 siblings) = 112

Therefore, based on Teresa's sample, approximately 112 students at Showton Middle School are likely to have more than 3 siblings.
