Write five expressions: a sum, a difference, a product, a quotient, and one that involves at least two operations that have the value of -3/4.

To find the perimeter of a square, you simply add up the lengths of all four sides. If we let "s" be the length of one side of the square, then the perimeter P can be found using the formula:

P = 4s

Since all four sides of a square are equal, we can simplify this expression to:

P = s + s + s + s = 4s

Therefore, the perimeter of the square is equal to 4 times the length of one side. If the length of one side is given in simplified radical form (such as √2 or √3), then the perimeter should also be expressed in simplified radical form.

For example, if the length of one side is 2√2 units, then the perimeter would be:

P = 4s = 4(2√2) = 8√2 units

5.13 U. S. Dollars will it cost to buy a gallon of gas in Canada. The correct answer to the question is A

Given in the question,

Cost of 1 liter gasoline = 1.50 Canadian dollars

1 gallon = 3.8 liters

Thus, to calculate the price of 1 gallon we multiply the cost of 1 liter by 3.8

Cost of 3.8 liters of gasoline = 1.5 * 3.8

= 5.70 Canadian dollars

1 Canadian dollar = 0.9 U. S. dollars

5.70 Canadian dollars = 5.70 * 0.9

= 5.13 U. S. dollars

That is the cost of 1 gallon of gas in Canada is 5 U S dollars and 13 cents.

Answer:

Ryan spent $72 on his shopping trip.

Step-by-step explanation:

To find out how much money Ryan spent, we need to add up the cost of the shirts and the sneakers.

First, we know that Ryan purchased two shirts for $16 each. So we can find the total cost of the shirts by multiplying the cost per shirt by the number of shirts:

So the total cost of the shirts is $32.

Next, we know that Ryan purchased a pair of sneakers that cost 2 1/2 times as much as a shirt. We can use this information to find the cost of the sneakers.

If the cost of a shirt is $16, then we can find the cost of the sneakers by multiplying $16 by 2 1/2:

So the cost of the sneakers is $40.

Finally, we can find the total cost of Ryan's shopping trip by adding up the cost of the shirts and the sneakers:

Therefore, Ryan spent $72 on his shopping trip.

The required answer is the double declining-balance method is $9,840.

To calculate the depreciation expense for 2020 using the double declining-balance method, we first need to determine the asset's straight-line depreciation rate. This is calculated by subtracting the residual value from the cost of the asset and dividing by the asset's useful life:

Depreciation base = $30,000 - $3,000 = $27,000
Annual depreciation expense (straight-line) = Depreciation base / Useful life = $27,000 / 5 = $5,400

Next, we need to determine the double declining-balance rate, which is twice the straight-line rate. Therefore:
Double declining-balance rate = 2 x (1 / Useful life) = 2 x (1 / 5) = 0.40 or 40%
Now we can calculate the depreciation expense for 2020:
Depreciation expense (2020) = Book value (beginning of year) x Double declining-balance rate

The book value at the beginning of 2020 would be the cost of the asset minus accumulated depreciation for the first year:
Book value (beginning of 2020) = $30,000 - ($5,400 x 1) = $24,600
As a result, depreciation increases during the initial year of possession and decreases thereafter.

Therefore:

Depreciation expense (2020) = $24,600 x 0.40 = $9,840

So the amount of depreciation expense for 2020, the second year of the asset's life,

using the double declining-balance method is $9,840.

Saved amount = $15,000

Value of the car = $26,795

Use the formula for compound interest to calculate the time it will take to reach $26,795 for each bank,

Bank A,

Initial investment ' P ' = $15,000

Annual interest rate ' r ' =5.45%

                                       =  0.0545

compounded continuously  'n'  = infinity

Target amount  'A' = $26,795

The formula for continuous compounding is,

A = P[tex]e^{rt}[/tex]

Substituting the values, we get,

⇒ 26,795 = 15,000 × [tex]e^{(0.0545t)}[/tex]

Solving for t, we get,

⇒ t = (log(26,795/15,000))/(0.0545)

     ≈ 9.4 years

It will take approximately 9.4 years to reach the target amount if we invest in Bank A.

Bank B,

Initial investment ' P ' = $15,000

The t-test statistic value that has a P-value of 0.10 when the alternative hypothesis is

(a) Ha: μ ≠ 0 is ±1.711.

(b) Ha: μ > 0 is 1.319.

(c) Ha: μ < 0 is -1.319.

(d) Ha: μ ≠ 0 is ±1.711.

To find the t-test statistic value for a given P-value and alternative hypothesis, we need to use a t-distribution table or a statistical software program. Here, we will use a t-distribution table to find the t-test statistic value for a sample of 24 observations and a P-value of 0.10 for each alternative hypothesis.

(a) Ha: μ ≠ 0 (two-tailed test)

The critical t-value for a two-tailed test with a P-value of 0.10 and degrees of freedom (df) of 23 (sample size - 1) is:

t = ±1.711

Therefore, the t-test statistic value that has a P-value of 0.10 when the alternative hypothesis is Ha: μ ≠ 0 is ±1.711.

(b) Ha: μ > 0 (one-tailed test)

The critical t-value for a one-tailed test with a P-value of 0.10 and df of 23 is:

t = 1.319

Therefore, the t-test statistic value that has a P-value of 0.10 when the alternative hypothesis is Ha: μ > 0 is 1.319.

(c) Ha: μ < 0 (one-tailed test)

The critical t-value for a one-tailed test with a P-value of 0.10 and df of 23 is:

t = -1.319

Therefore, the t-test statistic value that has a P-value of 0.10 when the alternative hypothesis is Ha: μ < 0 is -1.319.

(d) Ha: μ ≠ 0 (two-tailed test)

To find the t-test statistic value when Ha: μ ≠ 0, we can use the inverse t-distribution function in a statistical software program or a calculator. The t-test statistic value that corresponds to a P-value of 0.10 with 23 degrees of freedom is:

t = ±1.711

Therefore, the t-test statistic value that has a P-value of 0.10 when the alternative hypothesis is Ha: μ ≠ 0 is ±1.711.

Answer: To calculate the total amount a buyer should save each month to cover these fees, we need to add up all the costs and divide by 12 (the number of months in a year).

Annual real estate taxes = $2046

Insurance premiums = $1236

Flood insurance premiums = $380

Annual special assessment landfill fee = $125

Quarterly trash collection costs = $65 x 4 = $260

Annual homeowner's association fee = $720

Quarterly pool maintenance costs = $45 x 4 = $180

Monthly termite and pest protection costs = $39 x 12 = $468

Total annual costs = $2046 + $1236 + $380 + $125 + $260 + $720 + $180 + $468 = $5405

Step-by-step explanation:

You want the exact value of cos(-39π/6), and some angles, distances, and speeds related to the London Eye Ferris wheel.

The argument of the cosine function can be reduced:

  [tex]\cos{\left(-\dfrac{39\pi}{6}\right)}=\cos{\left(\dfrac{13\pi}{2}\right)}\qquad\text{using cos(-x)=cos(x)}[/tex]

We notice this is an odd multiple of π/2, so its value is 0.

  cos(-39π/6) = 0

The rate of movement is given as 2π radians (one revolution) in 30 minutes. Then the angle in 5 minutes is ...

  (5 min)(2π rad)/(30 min) = (2π/6) rad = π/3 rad

The passenger will travel π/3 radians in 5 minutes.

The arc length is given by ...

  s = rθ . . . . . . where r is the radius and θ is the central angle in radians

For a radius of (135/2 m) and an angle of π/3 radians, the distance traveled is ...

  s = (135/2 m)(π/3) = 45π/2 m ≈ 70.69 m

We know that 2π radians takes 30 minutes, so the time for 2 radians is ...

  t = (2 rad)·(30 min)/(2π rad)

  t = 30/π min ≈ 9.549 min . . . . about 9:32.96 min

The angular velocity is ...

  (2π rad)/(30 min) = (2π rad)/(30 min) × (1 min)/(60 s) = 2π/1800 rad/s

  = π/900 rad/s

360 degrees in 1800 seconds is ...

  360°/(1800 s) = (1/5)°/s

The wheel turns at the rate of 1/5 degree per second.

Additional comment

At one revolution per half hour, the wheel turns about twice as fast as the minute hand on a clock. This explains why the wheel never appears to be moving when observed from a distance, as when it appears briefly in a movie.

The monthly payment for a new car priced at $29,950 with financing the 8% TT&L and making a 25% down payment at a current finance rate of 3.16% for 36 months is approximately $698.62.

How to find calculate the monthly payment?

To calculate the monthly payment for a new car priced at $29,950 with the current finance rate of 3.16% for 36 months, we need to consider several factors, including the down payment and taxes.

First, we need to calculate the total cost of the car, including the taxes, title, and license (TT&L) fees. We can do this by adding 8% of the car's price ($29,950) to the price of the car, which comes to $32,346 ($29,950 + 8% of $29,950).

Next, we need to calculate the amount of the down payment. A 25% down payment on $32,346 comes to $8,086.50 ($32,346 x 0.25).

Subtracting the down payment from the total cost of the car gives us the amount we need to finance, which is $24,259.50 ($32,346 - $8,086.50).

Now, we can use a loan calculator to determine the monthly payment. Based on these figures, the monthly payment would be approximately $698.62 per month for 36 months.

In summary, to calculate the monthly payment for a new car priced at $29,950 with the current finance rate of 3.16% for 36 months, we need to consider the total cost of the car, including taxes and fees, the down payment, and the amount to be financed. The monthly payment is then calculated using a loan calculator, which gives us a monthly payment of $698.62 for 36 months.

The probability of getting heads and an even number is 1/4, and the probability of getting tails and a prime number less than 4 is 1/6.

To solve this, we need to use the multiplication rule of probability, which states that the probability of two independent events occurring together is the product of their individual probabilities.

Let's first find the probability of getting heads and an even number. Since there are two equally likely outcomes when flipping a coin (heads or tails), and three equally likely outcomes when rolling a die (1, 2, 3, 4, 5, or 6), the probability of getting heads and an even number is:

P(heads and even) = P(heads) x P(even)

= 1/2 x 3/6

= 1/4

Next, let's find the probability of getting tails and a prime number less than 4. The prime numbers less than 4 are 2 and 3. So, the probability of getting tails and a prime number less than 4 is:

P(tails and prime) = P(tails) x P(prime)

= 1/2 x 2/6

= 1/6

Therefore, the probability that Oscar gets heads and an even number is 1/4, and the probability that Oscar gets tails and a prime number less than 4 is 1/6.

Each car on Mabel's train is a little less than half a foot long i.e., 3/8 feet long, or 0.375 feet long. This is solved by using simple mathematical operations.

To find the length of each car on Mabel's train, we can use the formula:

Total length of train = length of one car × number of cars

We are given that Mabel's train has 8 cars and is 3 feet long, so we can substitute those values into the formula and solve for the length of one car:

3 = x × 8

where x is the length of one car.

To solve for x, we can divide both sides by 8:

3/8 = x

Therefore, each car on Mabel's train is 3/8 feet long, or 0.375 feet long.

In other words, each car is a little less than half a foot long.

To help visualize this, imagine dividing the 3-foot length of the train into 8 equal parts. Each part would be 3/8 feet long, which is the length of one car. So when Mabel puts all 8 cars together, they form a train that is 3 feet long.
