The elevation of Smallville is calculated by multiplying the elevation of Longfield by 4. Longfield's elevation is -144 1/2 feet, which is equivalent to -289/2 as an improper fraction. Multiplying this by 4 gives the elevation of Smallville as -578 feet.

To find Smallville's elevation, we first take the elevation of Longfield, which is -144 1/2 feet below sea level. Since Smallville is 4 times farther below sea level than Longfield, we have to multiply the elevation of Longfield by 4.

First, convert -144 1/2 to an improper fraction: -144 1/2 = -289/2.

Now, multiply by 4:

(-289/2) × 4 = -289 × 2 = -578 feet

So the elevation of Smallville is -578 feet below sea level.

Answer: The rate of interest per annum is 1.3%.

Step-by-step explanation:

Given  Principal P= $1000

time period n=3

Amount A=$1040,40

To find rate of interest per annum r

We know that

[tex]A=P(1+\frac{r}{100} )^3\\\Rightarrow\ 1040=1000(1+\frac{r}{100})^3\\\Rightarrow\ 1.040=(1+\frac{r}{100})^3\\\text{taking log on both sides}\\log(1.040)=3log(1+\frac{r}{100})\\\Rightarrow0.039=3log(1+\frac{r}{100})\\\Rightarrow0.013=log(1+\frac{r}{100})\\\\\Rightarrow\ e^{0.013}=(1+\frac{r}{100})\\\Rightarrow\ 1.013=(1+\frac{r}{100})\\\Rightarrow\ \frac{r}{100}=1.013-1=0.013\\[/tex]

⇒  r = 1.3%.

Final answer:

The surface area of the paper coffee filter with a radius of 6 centimeters and a slant height of 12 centimeters is approximately 339 square centimeters when rounded to the nearest whole number.

Explanation:

Finding the Surface Area of a Coffee Filter

To find the surface area of the paper coffee filter, we need to consider it as a part of a cone because a coffee filter is shaped like a cone with a circular base. The surface area of a cone is calculated by the formula Surface Area = πr(r + l), where r is the radius and l is the slant height. Given that the radius of the coffee filter is 6 centimeters and the slant height is 12 centimeters, the formula should be filled in as follows:

Radius (r) = 6 cm

Slant Height (l) = 12 cm

The calculation will then be:

Surface Area = π x 6 cm x (6 cm + 12 cm)

Surface Area = π x 6 cm x 18 cm

Surface Area = π x 108 cm²

Surface Area ≈ 3.14159 x 108 cm²

Surface Area ≈ 339.29 cm²

Rounding to the nearest whole number:

Surface Area ≈ 339 cm²

The surface area of the paper coffee filter is approximately 339 square centimeters.

The logarithm equation is equivalent to the exponential equation is c = log₃27

A logarithm is the power to which a number must be raised in order to get some other number.

Given that, exponential equation, [tex]3^{c}[/tex]=27

By the exponential form of logarithm:

[tex]x^{a} =m[/tex] then logarithm form is a = logₓ m

Therefore,

Answer : C) 12.8 cubic cm

The volume ( v) of a gas in a container at a constant temperature varies inversely as the pressure (p)

If y is  inversely proportional to x then [tex]y=\frac{k}{x}[/tex]

where k is constant of proportionality

v is  inversely proportional to p then [tex]v=\frac{k}{p}[/tex]

the volume of a gas is 24 cubic centimeters when the pressure is 16 pounds

Given : v= 24  and p = 16. We need to find out k

[tex]24=\frac{k}{16}[/tex]

Multiply by 16 on both sides

k = 384

Now we find out the volume under a pressure of 30 pounds

[tex]v=\frac{384}{30}[/tex]

[tex]v=\frac{128}{10}[/tex]= 12.8 cubic cm

Under a pressure of 30 pounds, the gas would occupy a volume of 12.8 cubic centimeters, as determined by applying Boyle's law, which states that volume and pressure are inversely proportional in conditions of constant temperature.

The volume (v) of a gas in a container at a constant temperature varies inversely as the pressure (p). This is a demonstration of Boyle's law, which states that pressure and volume are inversely proportional (P = k/V) when temperature is held constant. To find the new volume when the pressure changes, we can set up a proportion based on the original conditions provided: 24 cm³ at 16 pounds pressure. We set the initial volume and pressure as 24 cm³ and 16 lbs, respectively, and then solve for the new volume when the pressure is 30 lbs.

To find the volume under a pressure of 30 pounds, we use the equation:

V1 * P1 = V2 * P2

Where V1 is the original volume, P1 the original pressure, V2 the new volume, and P2 the new pressure. Plugging in our known values:

24 cm³ * 16 lbs = V2 * 30 lbs

Solving for V2, we get:

V2 = (24 cm³ * 16 lbs) / 30 lbs

V2 = 384 cm³ / 30 lbs

V2 = 12.8 cm³

Therefore, under a pressure of 30 pounds, the gas would occupy a volume of 12.8 cubic centimeters.

1. expand using place value.

337,060 = 300,000 + 30,000 + 7,000 + 000 + 60 + 0

Next, we will use exponents:

300,000 = 3 * 10^5

30,000 = 3 * 10^4

7,000 = 7 * 10^3

000 = 0 * 10^2

60 = 6 * 10

0 = 0 * 10^0

then after combing these exponents, we can write the number as:

337,060 = 3 * 10^5 + 3 * 10^4 + 7 * 10^3 + 0 * 10^2 + 6 * 10 + 0 * 10^0

Finally, removing the meaningless zeroes, we would end up with:

Answer:

The medium-sized can is the cheaper by the oz, and is $0.005 per oz. cheaper.

Step-by-step explanation:

Medium can:  $0.92/(46 oz) = $0.020/oz

Large can:   $3.60 / (144 oz) = $0.025/oz

Surprisingly, the medium can price per oz. is lower than that of the large can.  The difference is $0.005 per oz.

The medium can of tomato juice has the lower unit price at $0.02 per ounce, which is $0.005 lower per ounce than the large can's unit price of $0.025 per ounce.

To determine which can of tomato juice has the lower unit price, we need to calculate the cost per ounce for each can. For the medium can, we divide the cost by the number of ounces:

Medium can unit price = $0.92 / 46 ounces = $0.02 per ounce

For the large can, we perform a similar calculation:

Large can unit price = $3.60 / 144 ounces = $0.025 per ounce

The medium can has a lower unit price of $0.02 per ounce compared to the large can's unit price of $0.025 per ounce. The difference in unit price is $0.025 - $0.02 = $0.005, or half a cent per ounce.

if his bank charges him $7.50 each month for a balance below of $500

then Javier who did not deposit or withdraw (added or subtracted) but had a total of 305 would be charged 7.50 for those 3 months

305 - 7.50 (3) = X

305 - (22.5)

282.50

Answer: He had $277.50 at the end of 3 months.

Step-by-step explanation:

Since we have given that

Amount he had in his bank account = $305

Bank charges each month = $7.50

Number of months = 3

So, Bank charges for 3 months would be

[tex]7.50\times 3\\\\=\$22.5[/tex]

So, Amount left in his bank account would be

[tex]\$305-\$22.5\\\\=\$277.50[/tex]

Hence, he had $277.50 at the end of 3 months.

Step-by-step explanation:

The interest Nolan will earn after 7 years of time lapse, with the given figures, is $4,863,465 approx.

If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that simple interest, then the interest amount earned is given by:

[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]

For the considered case, the unit of time is weekly.

In 7 years, there can be at least 1 leap year, and at max 2 leap years.

In 7 years, therefore, the number of days are between [tex]6 \times 365 + 366[/tex] and [tex]6 \times 365 + 366+1[/tex] or say in between 2556 and 2557

Since each week has 7 days, therefore, the number of weeks these days will have is approx [tex]\dfrac{2556}{7} \approx 365.14[/tex] (assumed there are 2556 days in 7 years).

This approximates to 365  weeks (integer quantity)

Thus, we get:

Thus, the amount of interest that Nolan will earn is approx:

[tex]CI = P(1 +\dfrac{R}{100})^T - P\\\\CI \approx 2300(1 + 0.0212)^{365} - 2300 \approx 2300 \times 2115.65 - 2300\\CI \approx \$4,863,465[/tex]

Thus. the interest Nolan will earn after 7 years of time lapse, with the given figures, is $4,863,465 approx.

Final answer:

To prepare 30 ounces of a 50% hydrochloric acid solution, the chemist must mix 17 ounces of the 40% solution with 11 ounces of the 60% solution and 2 ounces of the 80% solution.

Explanation:

The student needs to mix different concentrations of hydrochloric acid to end up with 30 ounces of a 50% solution. We know that 2 ounces of the 80% solution are used, so the remaining 28 ounces must be a mix of the 40% and 60% solutions.

Let x represent the ounces of the 40% solution and 30 - 2 - x, or 28 - x, represent the ounces of the 60% solution. Setting up the equation based on mass of pure hydrochloric acid:

Solving for x:

The chemist needs to use 17 ounces of the 40% solution and 11 ounces of the 60% solution, combining them with the 2 ounces of the 80% solution to obtain 30 ounces of 50% hydrochloric acid.
