Answer:

Eqn of the problem: 2(3x + x) = 30

Solution: Width = 3.75 inches  and Length= 11.25 inches

Step-by-step explanation:

We are given;

We are required to represent the equation of the problem;

The formula for getting the perimeter of a rectangle is;

Perimeter = 2 (l+w)

In this case;

2(3x + x) = 30

Therefore;

The equation for the problem is;

2(3x + x) = 30

8x=30

Thus;

8x = 30

  x = 3.75 inches

 3x = 11.25 inches

Hence, the with is 3.75 inches while the length is 11.25 inches

The weight of 4 screws is 0.1 ounces

Step-by-step explanation:

The problem can be solved by setting up a proportion.

We can write the following proportion:

[tex]\frac{80}{2}=\frac{4}{x}[/tex]

where

x is the weight of 4 screws

Solving the equation, we find:

[tex]x=\frac{4\cdot 2}{80}=0.1[/tex]

Answer:

The plumber worked for 43 minutes.

Step-by-step explanation:

A plumber charged $70 for the first 30 minutes of each house call plus $4 for each additional minute he works.

Now, the total amount to be paid to the plumber C(x) as a function of x number of minutes that he works can be modeled by the equation

C(x) = 70 for x ≤ 30 minutes and C(x) = 70 + (x - 30)4 for x > 30 minutes.

Now, the plumber charges Hayden $122 for the house visit. In that case, x must be greater than 30 minutes.

So, we can write

122 = 70 + (x - 30)4

⇒ 122 = 70 + 4x - 120

⇒ 4x = 172

⇒ x = 43 minutes.

Therefore, the plumber worked for 43 minutes. (Answer)

Answer:

2(x-7) = 2

Step-by-step explanation:

First, let's look at the first part -- "Twice the difference of a number and 7".  The difference between a number (x) and 7 means x-7.  It also says twice the difference, so we are going to multiply x-7 by 2.  So that ends us with 2(x-7)

The last part -- "equals 2" means we will set what we currently have to 2.  2(x-7) = 2

Answer:

2(x-7)=2

Step-by-step explanation:

The difference of a number and 7 is x-7 (difference means subtract)

132,874,015 rounded to the nearest hundred thousand....

132,900,000 <===

The total amount is $ 780

Solution:

Let the total amount be "x"

Given that,

First person gets $ 268

Second person gets $ 200

Third person gets 40 %

This means, third person gets 40 % of total amount

Third person = 40 % of x

[tex]Third\ person = 40 \% \times x\\\\Third\ person = \frac{40}{100} \times x\\\\Third\ person = 0.4x[/tex]

We know that, total amount is equal to sum of amount got by all three persons

Total amount = first person + second person + third perosn

[tex]x = 268 + 200+ 0.4x\\\\x - 0.4x = 268 + 200\\\\0.6x = 468\\\\x = \frac{468}{0.6}\\\\x = 780[/tex]

Thus the total amount is $ 780

d = 5t + 20

Step-by-step explanation:

d represents the distance and t represents the time, in hours

Let he equation which model this situation ⇒ d = a t + b

Where a and b are constant.

Let the gas station is the starting point

So, at gas station t = 0 , d = 20

∴ 20 = 0 * a + b ⇒ b = 20

When he reaches home 2 hours later notes that he has traveled 30 miles.

and with substituting with b = 20

∴ 30 = 2 * a + 20

2a = 30 - 20 = 10  ⇒ a = 10/2 = 5

∴ d = 5t + 20

Final answer:

To find the distance between Ernie and Trevor in the camping scenario, trigonometry principles utilizing the law of sines can be applied effectively, resulting in a distance of approximately 15.54m between them.

Explanation:

To find the distance between Ernie and Trevor, we can use trigonometry. Let's focus on the triangle formed by Bert, Ernie, and Trevor. Since Bert and Ernie are 10m apart with a 30-degree angle at Bert, we can use the law of sines to find Ernie and Trevor's distance. By the law of sines:

For this case we have the following equation:

[tex]p + 2p + 3p = 12[/tex]

To solve we follow the steps below:

We add similar terms from the left side of the equation:

[tex]6p = 12[/tex]

We divide between 6 on both sides of the equation:

[tex]p = \frac {12} {6}\\p = 2[/tex]

Answer:

$14,800 at 10.5%

$38,850 at 12%

Step-by-step explanation:

Investment at 10.5% (x):

(0.12[$53,650 - x])/0.105x = 3

$6,438 - 0.12x = 0.315x

0.435x = $6,438

x = $14,800

Investment at 12%:

= $53,650 - $14,800

= $38,850

Answer: Investments: @ 10.5%, $14,800; @ 12%, $38,850

Proof: (income from 1st is 1/3 that of the income from the 2nd):

= (0.105[$14,800])/(0.12[$38,850])

= $1,554/$4,662

= 1/3

Let's denote as 'x' the amount of money invested by Ms. Burke at the rate of 10.5%. Given that the total amount of investment is $53,650, it follows that the remaining money invested at 12% is given by $53,650 minus 'x'.

The income from the 10.5% investment is 0.105 multiplied by 'x' and the income from the 12% investment is 0.12 multiplied by the quantity $53,650 minus 'x'.

According to the problem statement, the income from the 10.5% investment is one-third of the income from the 12% investment. Therefore, we can write down the following equation:

0.105*x = (1/3)*0.12*($53,650 - x)

We solve this equation to determine 'x'. The solution for this equation yields 'x' equal to approximately $14,800. This means Ms. Burke invested approximately $14,800 at 10.5%.

Also, we know that the difference between the total amount invested and the amount invested at 10.5% will give us the amount invested at 12%. Hence, by subtracting $14,800 from $53,650, we obtain $38,850.

Therefore, Ms. Burke invested approximately $14,800 at the rate of 10.5% and $38,850 at the rate of 12%.

To find the width of a 16-inch laptop screen that is 8 inches tall, we can use the 16:9 aspect ratio typical for screens and calculate that the width is approximately 14.22 inches.

Finding the Width of the Laptop Screen

To find out how wide a 16-inch laptop screen is, given that it is 8 inches tall, we can use the Pythagorean theorem assuming the screen has a 16:9 aspect ratio which is typical for laptop screens. To use the Pythagorean theorem, we first need to establish the diagonal (16 inches) as the hypotenuse of a right-angled triangle, with the height and width as the other two sides.

As per the given scale factor for this problem (1/160), it does not seem relevant to finding the width using the Pythagorean theorem. Instead, we can use the aspect ratio to find the width. For a 16:9 aspect ratio:

Height = 9x

Width = 16x

Given the height (8 inches) and assuming it to be 9x:

9x = 8 inches

x = 8 / 9

Now to find the width which is 16x:

Width = 16 * (8 / 9)

Width = 14.222... inches (approximately)

The width of the screen is therefore approximately 14.22 inches.
