Answer:

a) 42%

b) 62%

Step-by-step explanation:

a) (73+32)/250 × 100 = 42

b) (32+123)/250 × 100 = 62

58% of shoppers do not have access to a computer at home, and 62% of shoppers do not have an e-mail account.

Let's first calculate the total number of shoppers. From the survey, 250 people were interviewed. We want to find (a) The percentage of shoppers who do not have computer access at home and (b) the percentage of shoppers who do not have an e-mail account.

(a) According to the table, the number of shoppers who do not have computer access at home is 22 + 123 = 145. The percentage can be calculated as 145/250 * 100 = 58%. Therefore, 58% of shoppers do not have computer access at home.

(b) The number of shoppers who do not have an e-mail account equals 32 + 123 = 155. The percentage is calculated in the same way, 155/250 * 100 = 62%. Therefore, the percentage of shoppers who do not have an e-mail account is 62%.

Answer:

You would divide both sides by 0.05b, so that you would get h = A/0.05b

Step-by-step explanation:

SInce you are trying to isolate the variable, and the variable is being multiplied by 0.05b, you would simply do the opposite, or divide, in order to get h by itself.

Answer:

A=0.05bh  we divide both sides by "h"

A/h = .05b then we multiply both sides by 20

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]

Step-by-step explanation:

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).

Option C: [tex]a=3, b=4[/tex] is the value of a and b

Explanation:

Given that the expression [tex]\sqrt{648}=\sqrt{2^a\times3^b}[/tex]

We need to determine the value of a and b

Let us consider the term [tex]\sqrt{648}[/tex] and take the prime factorization of the term 648

Thus, we have,

648 divides by 2,

[tex]648=2 \cdot 324[/tex]

324 divides by 2,

[tex]648=2 \cdot 2 \cdot 162[/tex]

162 divides by 2,

[tex]648=2 \cdot 2 \cdot 2 \cdot 81[/tex]

81 divides by 3,

[tex]648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 27[/tex]

27 divides by 3,

[tex]648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 3 \cdot 9[/tex]

9 divides by 3,

[tex]648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 3 \cdot 3 \cdot 3[/tex]

Thus, we have,

[tex]\sqrt{648}=\sqrt{2^{3} \cdot 3^{4}}[/tex]

Therefore, equating the powers of 2 and 3, we get,

[tex]a=3, b=4[/tex]

Hence, the value of a and b is 3 and 4

Thus, Option C is the correct answer.

The values of a and b which make the equation true are; a = 3 and b = 4 respectively.

From the question; the expression given is;

[tex] \sqrt{648} = \sqrt{ {2}^{a} \times {3}^{b} } [/tex]

In essence; we have;

By expression of of 648 as the product of its lowest factors; we have;

In which case; we have;

Ultimately, the values of a and b which make the equation true are 3 and 4 respectively.

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.

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!
