Answer:

Total time = 19 minutes.

Step-by-step explanation:

Given the following data;

Time to shower = 720 seconds

Time to eat breakfast = 420 seconds

To find the total time in minutes;

Total time = 720 + 420

Total time = 1140 seconds

We know that 60 seconds equals a minute.

Total time = 1140/60

Total time = 19 minutes.

Therefore, it will take Andrew 19 minutes to take a shower and eat breakfast.

The value of the test statistic in the scenario given above is 3.487

The test statistic can be calculated as follows:

t = (mean - hypothesized mean) / (standard deviation / √(sample size))

mean = 98.7

hypothesized mean = 98.5

standard deviation = 0.5

sample size = 76

Plugging these values into the formula, we get the following test statistic:

t = (98.7 - 98.5) / (0.5 / √(76)) = 3.487

Therefore, the value of the test statistic in the above scenario is 3.487

Based on the calculated tax rate, we can conclude that the correct answer is: A rate equal to or greater than 36.19% but less than 50.03%

The relevant net income is given as $345,000. This represents the taxable income before considering any tax deductions or exemptions.

To calculate the tax expense, we need to know the tax rate. Let's assume the tax rate as 'x'.

Tax Expense = Taxable Income * Tax Rate

Given:

Relevant Net Income = $345,000

Since the tax expense is not directly provided, we can rearrange the formula to solve for the tax rate:

Tax Rate = Tax Expense / Taxable Income

From the given information, we can calculate the tax expense:

Tax Expense = Relevant Net Income - Relevant Depreciation

Tax Expense = $345,000 - $130,000 = $215,000

Now we can calculate the tax rate:

Tax Rate = Tax Expense / Relevant Net Income

Tax Rate = $215,000 / $345,000

Tax Rate ≈ 0.6231884 or 62.32% (rounded to two decimal places)

Based on the calculated tax rate, we can conclude that the correct answer is:

A rate equal to or greater than 36.19% but less than 50.03%

The dog's running speed of 5 km/hr can be converted to approximately 3.125 mi/hr by multiplying it by the conversion factor of 1 mi/1.6 km. Rounding to the nearest thousandth, the dog can run at about 3.125 mi/hr.

To convert the dog's running speed from kilometers per hour (km/hr) to miles per hour (mi/hr), we need to use the conversion factor of 1.6 km = 1 mi.First, we can convert the dog's speed from km/hr to mi/hr by multiplying it by the conversion factor: 5 km/hr * (1 mi/1.6 km) = 3.125 mi/hr.

However, we need to round the answer to the nearest thousandth (three decimal places). Since the digit after the thousandth place is 5, we round up the thousandth place to obtain the final answer.

Therefore, the dog can run at approximately 3.125 mi/hr.

Tom should choose the bank that gives the highest interest rate on savings accounts

The amount a lender charges a borrower is called an interest rate, and it is expressed as a percentage of the principal, or the loaned amount. Typically, a loan's interest rate is expressed as an annual percentage rate, or APR.

A savings account or certificate of deposit earnings at a bank or credit union may also be subject to an interest rate (CD). The interest received on these deposit accounts is measured in annual percentage yields. In this case, the one that gives the best rate is the best option to choose.

Answer:

\(\frac{-13}{5}\) or -2.6

Step-by-step explanation:

To do this you would first have the equation \(5(x+4)=12\) and then you could multiply the x+5 by 5 which is 5x+25 so then your equation would be \(5x+25=12\) then you would subtract 25 from both sides to cancel out the 25 so then your equation would look like this \(5x=-13\) then you would divide from both sides to just get x so you would get  \(x=\frac{-13}{5}\) so you could leave it as is or you could turn it into a decimal which is -2.6

Answer:

Full drum 80 dollars

one lid missing

earn 10 dollars less

Step-by-step explanation:

We need to find the surface area

SA = 2 pi r^2  + 2 pi rh

The diameter is 2 so the radius = 2/2 =1

SA = 2 * pi * 1^2  + 2 * pi * 1 * 3

      = 2 pi + 6pi

      = 8pi

Using pi = 3.14

SA = 8 *3.14 = 25.12 ft^2

We get 3.18 per ft^2

25.12 * 3.18 =79.88

To the nearest dollar

80 dollars

If one of the lids is missing

SA =  pi r^2  + 2 pi rh

        pi + 6pi

        7 pi

Using pi = 3.14

SA = 7 *3.14 = 21.98 ft^2

We get 3.18 per ft^2

21.98 * 3.18 =69.90

To the nearest dollar

\(\rule[225]{225}{2}\)

Step-by-step explanation:

Surface area of the cylinder :

2πr² + 2πrh

The diameter is 2 ft, so the radius is 1 ft.

⇒ 2π(1)² + 2π(1)(3)

⇒ 8π ≈ 25.13

$3.18 is getting payed per square foot.

⇒ 25.13 × 3.18

⇒ 79.9221171073 ≈ 80

If the lid was missing:

πr² + 2πrh

π(1)² + 2π(1)(3)

7π ≈ 21.99

$3.18 is getting payed per square foot.

⇒ 21.99 × 3.18

⇒ 69.9318524689 ≈ 70

The difference :

80 - 70 = 10

$10 less if the lid is missing.

To determine the number of gallons of paint needed to cover office 143, we need to know the square footage of the office.

Once we have that information, we can divide the square footage by the coverage rate per gallon to calculate the required amount of paint.

Let's assume the square footage of office 143 is 800 square feet.

Number of gallons needed = Square footage / Coverage rate per gallon

Number of gallons needed = 800 square feet / 50 square feet per gallon

Number of gallons needed = 16 gallons

Therefore, you would need approximately 16 gallons of paint to cover office 143, assuming each gallon covers 50 square feet.

Answer: 0.39

Step-by-step explanation:

We are required to determine the the value of f, rounded to the nearest hundredth

The value of f, rounded to the nearest hundredth is 0.39

Given function:

\(d(v) = \frac{2.15 {v}^{2} }{64.4f} \)

Where,

d = stopping distance in feet

v = initial velocity in miles per hour

f = a constant related to friction

When

v = 40 mph

d = 138 ft

f = ?

\(d(v) = \frac{2.15 {v}^{2} }{64.4f} \)

\(138= \frac{2.15 {(40)}^{2} }{64.4f} \)

138(64.4f) = 2.15(1600)

8,887.2f = 3440

f = 3440 / 8,887.2

f = 0.3870735439733

Answer:

≈ 3.9 miles

Step-by-step explanation:

The third angle in the triangle is

180° - (53 + 78)° = 180° - 131° = 49°

Using the Sine rule in the triangle with distance from 2 being x, then

\(\frac{3}{sin49}\) = \(\frac{x}{sin78}\) ( cross- multiply )

x × sin49° = 3 × sin78° ( divide both sides by sin49° )

x = \(\frac{3sin78}{sin49}\) ≈ 3.9 ( to the nearest tenth )

The rate of change of the water's level when the height of the water is 4cm is approximately 0.030 cm/s. This can be solved by the concept of Surface area and volume.

Let's first find the volume of water in the conical cup when the height of the water is 4cm. We know that the volume of a cone is given by the formula V = (1/3)πr^2h, where r is the radius of the base, h is the height, and π is a constant approximately equal to 3.14.

In this case, the radius of the base is half the width of the cup, so r = 2cm. The height of the water is 4cm, so h = 4cm. Therefore, the volume of water in the cup is V = (1/3)π(2cm)^2(4cm) = 16.76 cm^3 (rounded to two decimal places).

We know that water is leaking out of the bottom of the cup at a rate of 3cm^3/s. Therefore, the rate of change of the volume of water in the cup is -3cm^3/s (negative because the volume is decreasing).

We want to find the rate of change of the water's level, which we can call dh/dt. We can use related rates to find this. We know that the volume of water in the cup is decreasing at a rate of -3cm^3/s, and we want to find the rate of change of the height of the water, dh/dt, when the height is 4cm.

Using the formula for the volume of a cone, we can solve for h in terms of V:

V = (1/3)πr^2h

3V = πr^2h

h = (3V)/(πr^2)

Now we can differentiate both sides with respect to time:

dh/dt = (3/πr^2)(dV/dt)

Substituting in the values we found earlier, we get:

dh/dt = (3/π(2cm)^2)(-3cm^3/s)

dh/dt = -0.030 cm/s

Therefore, the rate of change of the water's level when the height of the water is 4cm is approximately 0.030 cm/s.

The integral we are trying to solve is int sin x , dx, with a change of variables or the accompanying table. The first step is to determine the change of variables from x to u. In this case, we will use the substitution u=4+cos x. With this substitution, we can rewrite the integral as \int \sin x \, du.

Next, we can use the table of general integration formulas to evaluate the integral. The formula for int sin x , du is cos x + C, where C is a constant of integration. Plugging in our substitution, we have cos (4+cos x) + C.
Finally, we can evaluate the integral by solving for C. We can do this by setting the equation equal to 0, since we are evaluating a definite integral. This yields C=cos (4+cos x), so the answer to the integral is cos (4+cos x).
