- When the price for the TV is $190, there are 500 TVs sold.

The other sentence "A total of 190 TVs can be sold if the price is set at $500. When the price for the TV is $500, there are 190 TVs sold" is not correct as it has the price and the quantity of TVs sold reversed.

In interpretation, it is important to pay attention to the context and the logic of the problem to ensure that the sentence accurately reflects the information provided. In this case, the correct interpretation sentences reflect the relationship between the price and the quantity of TVs sold.

Robyn has 4 important files saved on her computer.

To solve this problem, we can use a simple formula that relates the total space occupied by the files to the size of each file:

Total space occupied = Size of each file x Number of files

In this case, we know the total space occupied (84.6 megabytes) and the size of each file (21.15 megabytes), so we can rearrange the formula to solve for the number of files:

Number of files = Total space occupied ÷ Size of each file

Plugging in the values we know, we get:

Number of files = 84.6 megabytes ÷ 21.15 megabytes per file

Simplifying this expression gives us:

Number of files = 4

Therefore, Robyn has 4 important files saved on her computer.

It's important to note that this problem assumes that each file uses exactly 21.15 megabytes of memory. In reality, file sizes can vary depending on their content, so this may not always be the case. Additionally, it's worth noting that file size can be affected by various factors such as compression and encoding, so the actual size of a file on disk may differ from its theoretical size. Nonetheless, for the purposes of this problem, we can assume that each file uses exactly 21.15 megabytes of memory.

The number of years that it will take for the Valence of the account to be $6500 = 6.9 years

Annual simple interest is defined as the amount of money that is being paid to an individual who invested a specific amount of money for a period of time.

The principal amount = $4000

The rate for earnings= 9%

The simple interest= $6500 - 4000 = 2500

Time = X

Using the formula:

Simple interest = P ×T×R/100

Make T the subject of formula;

T = Simple interest × 100/ P × R

T = 2500 × 100/ 4000× 9

T = 250000/36000

On January 31st, the money invested would have amounted to $10,737,418.

What is meant by investment?

An asset or object acquired with the intention of creating income or recognition is referred to as an investment. The purchase of products that are not consumed right away but will be utilised to create wealth down the road is referred to as an investment in an economic outlook. An investment in finance is a financial asset that is purchased with the expectation that it will either continue to generate income or be sold at a profit at a later date.

Given,

 A penny is invested on January 1.

It doubles each day.

We should find the amount on January 31.

First day = 1

Second day = 2

Third day = 4

Fourth day = 8

So basically if it is the xth day of January, then the amount on that day is 2ˣ⁻¹

Therefore on the January 31st, the money invested would have amounted to

2³¹⁻¹ = 2³⁰ = 1,073,741,824 pennies = $10,737,418.24 = $10,737,418

The reported sky cover is one continuous overcast layer, its thickness is 5,780 feet.

To calculate the thickness of a cloud layer, you need to subtract the cloud base height from the cloud top height. In this case, the sky cover is reported as one continuous layer, and the cloud top is reported at 6,500 feet.

Aviation Routine Weather Reports (METARs) typically include cloud height information in increments of 100 feet above ground level (AGL). If the sky cover is reported as overcast (OVC) with no height information, it is assumed to be at or below 6,000 feet AGL.

Therefore, the thickness of the cloud layer in this scenario can be calculated as follows:

Cloud base height = 620 feet (field elevation) + 100 feet = 720 feet AGL

Cloud thickness = Cloud top height - Cloud base height

= 6,500 feet - 720 feet

= 5,780 feet

Step-by-step explanation:

Answer:

Option A and C

Step-by-step explanation:

First of all we know the speed formula,

\(Speed=\frac{distance}{Time}\)

So to find time,

\(Time=\frac{distance}{speed}\)

Now let’s find the time of each option

Option a:

Speed = 60 mph

Distance : 120 miles

Time = 120/60

= 2 hours

Therefore option a is correct

Option b:

Speed = 3 mph

Distance = 1.5 miles

Time = 1.5/3

= 1/2 hours

Therefore option b is not applicable.

Option c:

Speed = 80 mph

Distance = 160 miles

Time = 160/80

= 2 hours

Therefore option c is correct.

Option A and C are the answers

The total area of the back and side walls that should be painted is 57 square meters.

To calculate the total area of the back and side walls that need to be painted, we need the dimensions of the walls. Let's assume we have the following dimensions:

Back Wall:

Height = 3 meters

Width = 5 meters

Side Wall 1:

Height = 3 meters

Length = 8 meters

Side Wall 2:

Height = 3 meters

Length = 6 meters

To calculate the area of each wall, we multiply the height by the width/length:

Area of Back Wall = Height * Width = 3 meters * 5 meters = 15 square meters

Area of Side Wall 1 = Height * Length = 3 meters * 8 meters = 24 square meters

Area of Side Wall 2 = Height * Length = 3 meters * 6 meters = 18 square meters

To calculate the total area of the back and side walls that need to be painted, we add up the individual areas:

Total Area = Area of Back Wall + Area of Side Wall 1 + Area of Side Wall 2

          = 15 square meters + 24 square meters + 18 square meters

Using binary search to find the key 60 in the given list, the elements compared in order are: 38, 76, 60.

1. We start by comparing the key (60) to the middle element of the list, which is 38. Since 60 is greater than 38, we know that the key must be in the second half of the list.
2. Next, we compare the key to the middle element of the second half of the list, which is 76. Since 60 is less than 76, we know that the key must be in the first half of the second half of the list.
3. We then compare the key to the middle element of the first half of the second half of the list, which is 50. Since 60 is greater than 50, we know that the key must be in the second half of the first half of the second half of the list.
4. Next, we compare the key to the middle element of the second half of the first half of the second half of the list, which is 72. Since 60 is less than 72, we know that the key must be in the first half of the second half of the first half of the second half of the list.
5. Finally, we compare the key to the middle element of the first half of the second half of the first half of the second half of the list, which is 60. Since 60 is equal to 60, we have found the position of the key in the list.

The mass of salt in the tank at time t.

dS/dt = 10 - S/400

S(0) = 100 grams

The solution is S(t) = 4000 - 3900\(e^{\frac{-t}{400}}\)

A tank holds water V(0) = 4000 liters in which salt S(0) = 100 grams.

So dS/dt = S(in) - S(out)

S(in) = 1 × 10 = 10 gram/liters

S(out) = S/V × 10 = 10S/V gram/liters

V = V(0) + q(in) - q(out)

V = 4000 + 10t - 10t

V = 4000 liters

dS/dt = 10 - 10S/V

dS/dt = 10 - 10S/4000

dS/dt = 10 - S/400

Now given; S(0) = 100.

Here, p(t) = 1/400, q(t) = 10

\(\int p(t)dt = \int\frac{1}{400}dt\)\(\int p(t)dt = \frac{1}{400}t\)

\(\mu=e^{\int p(t)dt}\)

\(\mu=e^{\frac{t}{400}}\)

So, S(t) = \(\frac{\int\mu q(t)dt+C}{\mu}\)

S(t) = \(\frac{\int e^{\frac{t}{400}} \cdot10dt+C}{e^{\frac{t}{400}}}\)

S(t) = \(e^{\frac{-t}{400}} \left({\int e^{\frac{t}{400}} \cdot10dt+C}\right)\)

S(t) = \(e^{\frac{-t}{400}} \left({10\times\frac{e^{\frac{t}{400}}}{1/400} +C}\right)\)

S(t) = \(e^{\frac{-t}{400}} \left({4000\times{e^{\frac{t}{400}} +C}\right)\)

Now solving the bracket

S(t) = 4000 + \(e^{\frac{-t}{400}}\)C.....(1)

At S(0) = 100

100 = 4000 + \(e^{\frac{-0}{400}}\) C

100 = 4000 + \(e^{0}\) C

100 = 4000 + C

Subtract 4000 on both side, we get

C = -3900

Now S(t) = 4000 - 3900\(e^{\frac{-t}{400}}\)

The value of x in the expression -2/9=8/(-3x) will be 12.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.

Given

-2/9 = 8/(-3x)

By cross multiplication

-2 = 8 × 9/(-3x)

-2 = -8 × 3/x

Again cross multiplication

x = 24/2

x = 12

Hence the value of x will be 12.
