Answer: 20

Step-by-step explanation:

C = 5/9 (f - 32)

since f = 68 and substitute it into the equation above

C = 5/9 ( 68 - 32)

C = 5/9 (36)

opening the bracket

C = 5/9 x 36

C = 180/9

C = 20

Answer:

Each result is equally likely

The sample space has 36 different outcomes

Step-by-step explanation:

A number cube has 6 sides, and there are 2 number cubes so there are 36 possible outcomes because 6²=36

Remind me if im wrong

The statements which are true are each result is equally likely , the sample space has 36 different outcomes and the total roll of 7 is very likely.

When a green number cube and a red number cube are rolled, the outcomes indeed have specific characteristics. Here's a breakdown based on the selections provided in the question:

Each result is equally likely is true, because when rolling two fair six-sided dice (or in this case, cubes), each side of each cube has an equal chance of landing face up, making each combination of the two cubes equally likely

The sample space has 36 different outcomes is  true, as each cube has 6 faces, and when two are rolled together, the total number of possible outcomes (or the sample space) is 6 times 6, equating to 36

The sample space has 11 different outcomes is false, because as previously stated, there are 36 possible outcomes based on the combination of two six-sided dice.

A total roll of 7 is very likely is true, not because it will happen every time, but because there are more combinations (6 in total) that sum to 7 than any other number. These are (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1).

Answer:x^2-6x+9

Step-by-step explanation:

Answer:

a) rational

b) irrational

Step-by-step explanation:

a) 36 = 6²

So sqrt(36) = 6

b) 72 = 2 × 36

sqrt(72) = sqrt(2) × sqrt(36)

Since 2 is not a perfect square, sqrt(72) is irrational

Final answer:

√36 is a rational number because 36 is a perfect square, which results in a whole number when square rooted. However, √78 is an irrational number as it is not a perfect square and cannot be simplified to a fraction of two integers.

Explanation:

We are tasked with determining whether each given root, √36 and √78, is a rational or irrational number. First, we observe that √36 is the square root of 36. Since 36 is a perfect square (6 x 6), √36 equals 6, which is a rational number because it can be expressed as the quotient of two integers (6/1).

On the other hand, √78 is not a perfect square; its square root cannot be simplified to a whole number or a simple fraction of two integers. Therefore, √78 is an irrational number because it cannot be written exactly as a simple fraction or repeating or terminating decimal.

Answer:

Step-by-step explanation:

Students learn that the prime factorization of a number is the given number written as the product of its prime factors. For example, to find the prime factorization of 45, use a factor tree to find that 45 is 5 x 9, and 9 is 3 x 3. So the prime factorization of 45 is 5 x 3 x 3, or 5 x 3^2.

Answer:

Option B, 3^2 * 5

Step-by-step explanation:

Step 1:  Find the prime factorization of 45

45 = 9 * 5

9 can be simplified as 3^2

5 cannot be simplified because it is a prime number

9 * 5

3^2 * 5

So, 45 = 3^2 * 5

Answer below, let me know if it didn't make sense.  

Step-by-step explanation:

I attached a picture of the scatterplot with a line connecting the points.  There is a definite upside down u type shape, and it doesn't look close to a line at all, so linear is not a good choice.  

an upside down u shape (or right side up u shape for that matter) is exactly what a quadratic is, or any polynomial if you do it right, but quadratic is the simplest, so let's go with that.

A linear representation is not the best way to represent the data from the equation gotten from the regression calculator.

Regression simply means a statistical measurement that is used to determine the strength of the relationship that exists between the dependent and independent variables.

In this case, a linear representation is not the best way to represent the data from the equation. A quadratic equation will have been more appropriate in this case.

Answer :

Toby: 4 of the $1.64, 1 of the $0.77, and 1 of the $3.59

Elisa: 3 of the $3.59

Heidi: 3 of the $3.59, and 1 of the $0.77

The question is a math problem about calculating the total cost of purchased fruits within a given budget. It requires us to determine the fruit combinations that match the total spending amount and the number of items bought for each individual.

The problem is a typical mathematics question focusing on money and budgeting. Toby, Elisa, and Heidi each have a budget between $10 and $12 to spend on fruit. Each fruit item's cost is given, and we need to assign a combination of fruits to each person that matches their total spending amount. Toby bought 6 items, Elisa bought 3, and Heidi bought 4.

For example, if Toby bought 6 bananas at 20 cents each, his total would be $1.20. As he needs to spend between $10 and $12, you would continue to mix and match the rest of the fruits until his purchase meets the criteria of total amount spent and number of items bought.

The measure of arcWUX in circle V of the given diagram with the circle geometry is; C: 120°

From the complete image as seen online, we can say that;

The measure of ∠WUX is similar to the measure of vertex ∠V.

To get the measure of angle V (∠V), we will use the sum of angles in a triangle theorem to get;

30 + ∠V + ∠X = 180

60 + ∠V = 180

∠V = 180 - 60

∠V = 120°

Since ∠V = arcWUX

Then, measure of arcWUX is 120°

Answer:

The first thing we need to do is find the area of the rectangle...

l x w = A

7 x 8 = 56

So the area of the first rectangle is 56m.

Now we multiply each dimension by 5...

8 x 5 = 40

7 x 5 = 35

So, now the width is 40m and the length is 35m,

Then, find the area of the new rectangle...

35 x 40 = 1400

The area of this rectangle is 1,400m!

1,400 / 56 = 25

So, by multiplying each dimension by 5, the area is now multiplied by 25!

12*2=24mm is the answer

The measure of the matching side of the smaller triangle is 24 millimeters.

When dealing with similar triangles, the lengths of corresponding sides are proportional. This means that if one triangle has sides that are a constant multiple of the sides of another triangle, we can find the length of a matching side by using that constant multiple. In this case, the sides of the smaller triangle are said to be 2/3 the lengths of the sides of the larger triangle.

To find the matching side of the smaller triangle when a side of the larger triangle is 36 mm, we use the proportionality factor, which is 2/3. Therefore, the length of the corresponding side in the smaller triangle is 2/3 of 36 mm, which can be calculated as:

(2/3) * 36 mm = 24 mm

So, the measure of the matching side of the smaller triangle is 24 millimeters.

Answer:

In 1981 was the building worth double it’s value.

Step-by-step explanation:

Given : A townhouse in San Francisco was purchased for $80,000 in 1975. The appreciation of the building is modeled by the equation : [tex]A=80000(1.12)^t[/tex], where t represents time in years.

To find : In what year was the building worth double it’s value in 1975?

Solution :

The amount is $80,000.

The building worth double it’s value in 1975.

i.e. amount became A=2(80000).

Substitute in the model,

[tex]2(80000)=80000(1.12)^t[/tex]

[tex](1.12)^t=\frac{2(80000)}{80000}[/tex]

[tex](1.12)^t=2[/tex]

Taking log both side,

[tex]t\log (1.12)=\log 2[/tex]

[tex]t=\frac{\log 2}{\log (1.12)}[/tex]

[tex]t=6.11[/tex]

i.e. Approx in 6 years.

So, 1975+6=1981

Therefore, in 1981 was the building worth double it’s value.

The building was worth double its value in [tex]1975[/tex] around the year [tex]1981[/tex]

To determine in what year the building was worth double its value in [tex]1975[/tex], we need to set up the equation based on the appreciation model given:

[tex]\[ A = 80000 \times (1.12)^t \][/tex]

Here, [tex]\( A \)[/tex] represents the current value of the townhouse in dollars, and [tex]\( t \)[/tex] represents the time in years since [tex]1975.[/tex]

We want to find the year [tex]\( t \)[/tex] when the value [tex]\( A \)[/tex] is double the initial value of [tex]\$80,000[/tex]

[tex]\[ A = 2 \times 80000 = 160000 \][/tex]

Now, substitute [tex]\( A = 160000 \)[/tex] into the equation:

[tex]\[ 160000 = 80000 \times (1.12)^t \][/tex]

Divide both sides by [tex]80000[/tex] to solve for [tex]\( (1.12)^t \)[/tex]

[tex]\[ 2 = (1.12)^t \][/tex]

To solve for [tex]\( t \)[/tex], take the natural logarithm ([tex]ln[/tex]) of both sides:

[tex]\[ \ln(2) = \ln((1.12)^t) \][/tex]

[tex]\[ \ln(2) = t \times \ln(1.12) \][/tex]

Now, divide both sides by [tex]\( \ln(1.12) \)[/tex] to solve for [tex]\( t \)[/tex]:

[tex]\[ t = \frac{\ln(2)}{\ln(1.12)} \][/tex]

Using a calculator to find the approximate value:

[tex]\[ t = \frac{0.6931}{0.1178} = 5.88 \][/tex]

Since [tex]\( t \)[/tex] represents years after [tex]1975[/tex], we add this to [tex]1975[/tex] to find the year when the building was worth double its value in [tex]1975[/tex]:

[tex]\[ \text{Year} = 1975 + 5.88 = 1980.88 \][/tex]

In [tex]1981[/tex], the building was worth double its value in [tex]1975.[/tex]
