The number of square feet of wallpaper that Austin will need for the large wooden storage boxes would be = 1,296 ft².

To calculate the amount of wallpaper needed, we should find the area of the rectangular prism.

The formula for the area of rectangular prism = 2 (lh +wh + lw ).

Where;

Length (l) = 6ft

width (w) = 3ft

Height (h) = 6ft

area = 2( 6×6 + 3×6 + 6×3)

= 2( 36+18+18)

= 2( 72)

= 144 ft²

Therefore the amount of wallpaper needed = 144× 9 = 1296 ft².

55.0% of the people surveyed were satisfied with the car.

We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.

Formula for percentages is (Value/Total value) x 100.

If two values are presented to us, we must determine the percentage difference between them.

Given that, 1,705 said they would buy that type of car again.

Thus, to find people who were satisfied with the car:

Percentage = (Number of satisfied people / Total number of people) x 100%

Percentage = (1,705 / 3,100) x 100% = 55.0%

Hence, 55.0% of the people surveyed were satisfied with the car.

For the equation 7/8 - 6/11, the best estimation is obtained as (1) - (1/2) = 1/2

To estimate 7/8 - 6/11, we need to find a common denominator for the two fractions.

One way to do this is to multiply the numerator and denominator of each fraction by the denominator of the other fraction.

So, we have -

(7/8) x (11/11) - (6/11) x (8/8)

= 77/88 - 48/88

= (77 - 48)/88

= 29/88

To simplify this fraction, we can look for common factors in the numerator and denominator.

The fraction 7/8 is almost 1 and the fraction 6/11 is almost 1/2.

Therefore, the best estimation of the equation 7/8 − 6/11 is -

(1) - (1/2) = 1/2

Therefore, the equation is obtained as (1) - (1/2) = 1/2.

The slope of a line is a measure of its steepness or inclination. It tells us how much the line rises or falls as we move horizontally along it.

Parallel lines will have the same slope. That means if two lines are parallel, they have the same steepness or inclination.

Here we have

Equation of the line is y = 3x --- (1)

Equation(1) is in the form y = mx + x

The slope of the line (1) = 3

Let y = m₁x + c is the line that is parallel to line (1)  

Since the slope of the parallel lines are equal

=> y = 3x + c --- (2)

Given that the line passes through (7, 1)

=> 1 = 3(7) + c

=> c = - 21 + 1

=> c = - 20  

Hence, the equation of the line is y = 3x - 20 --- (3)

It is given that the line will also pass through the point (k, 7)

The total cost for the customer for the entire year is  $48,600.

The customer wants to purchase 20 subscriptions for each of their 20 employees, so they need a total of 20 x 20 = 400 subscriptions.

Each subscription costs $10 per month for a yearly commitment,

so the cost for one subscription for a year would be $10 x 12 = $120.

Therefore, the total cost for 400 subscriptions for a year would be $120 x 400 = $48,000.

In addition, they need 1 extra subscription for a different service for every two employees, so they need 20 / 2 = 10 extra subscriptions.

Each extra subscription costs $5 per month for a yearly commitment, so the cost for one extra subscription for a year would be $5 x 12 = $60.

Therefore, the total cost for 10 extra subscriptions for a year would be $60 x 10 = $600.

Adding the cost of the extra subscriptions to the cost of the regular subscriptions, the total cost for the customer for the entire year would be $48,000 + $600 = $48,600.

The single equivalent discount rate for Company A is 19.28%, and for Company B is 23.18%.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

We are given;

The measures of company A and B= 8/10/14/4 10/6/16/3

Now,

To calculate the single equivalent discount rate for each company, we can use the following formula:

Single equivalent discount rate = [(1 - (Discount % / 100)) ^ (365 / Average payment period) - 1] x 100

For Company A, the average payment period is:

(8 + 10 + 14 + 4) / 4 = 9

Using the formula, we can calculate the single equivalent discount rate for Company A:

Single equivalent discount rate = [(1 - (8/100)) ^ (365 / 9) - 1] x 100 = 19.28%

For Company B, the average payment period is:

(10 + 6 + 16 + 3) / 4 = 8.75

Using the formula, we can calculate the single equivalent discount rate for Company B:

Single equivalent discount rate = [(1 - (10/100)) ^ (365 / 8.75) - 1] x 100 = 23.18%

Answer:

x = 13

Step-by-step explanation:

We know that 5x, x+12, and 90 makes a straight line, which is 180 degrees

5x + x+12 + 90 = 180

Combine like terms.

6x+102=180

Subtract 102 from each side.

6x+102-102=180-102

6x = 78

Divide each side by 6

6x/6 = 78/6

x = 13

Answer:

x = 13

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

We know that,

→ The angle of right angle is 90°.

Forming the equation,

→ (x + 12)° + (5x)° = 90°

Then the value of x will be,

→ (x + 12)° + (5x)° = 90°

→ x + 12 + 5x = 90

→ (x + 5x) + 12 = 90

→ 6x + 12 = 90

→ 6x = 90 - 12

→ 6x = 78

→ x = 78 ÷ 6

→ [ x = 13 ]

Hence, the value of x is 13.

The pair of lines 12x + 4y = 9 and 12x = 36y + 48 are perpendicular.

From the question, we are to determine whether the pair of lines are parallel, perpendicular or neither

To determine whether the pair of lines are parallel, perpendicular, or neither, we need to compare their slopes.

We can rewrite both equations in slope-intercept form, y = mx + b,

Where m is the slope of the line:

12x + 4y = 9

4y = -12x + 9

y = (-3/1)x + 9/4

12x = 36y + 48

12x - 48 = 36y

(1/3)x - 4/3 = y

The slope of the first line is -3/1, and the slope of the second line is 1/3.

Parallel lines have the same slope, so these lines are not parallel.

Perpendicular lines have slopes that are negative reciprocals of each other, meaning their slopes multiply to -1. Therefore, these lines are perpendicular.
