Answer:

6:20

Step-by-step explanation:

The time 50 minutes before 07:10 will be 06:20.

The y-intercept of the line with slope of m = -3/2 and passing though the point (-6, 2) is -7.

The equation of a straight line is y=mx+c y = m x + c m is the gradient and c is the height at which the line crosses the y-axis, also known as the y -intercept.

Given that, a line has a slope of m = -3/2 and the point (-6, 2) lies on the line, we need to find the y-intercept,

The general equation of the line in slope-intercept form is given by, y = mx+c,

Where, c is the y-intercept and m is the slope of the line,

Therefore, the equation of the asked line in terms of c is:-

y = -3x/2+c.....(i)

To find the value of c, put x = -6 and y = 2,

Therefore,

2 = -3(-6)/2+c

2 = 18/2 + c

2 = 9 + c

c = -7

Since, c is the y-intercept

Hence, the y-intercept of the line with slope of m = -3/2 and passing though the point (-6, 2) is -7.

To find the sale price of a bottle of perfume after a 13.4% discount, we need to first calculate the amount of the discount, and then subtract that amount from the original price.

The discount rate is 13.4%, which can be written as a decimal as 0.134. To calculate the amount of the discount, we can multiply the original price by the decimal equivalent of the discount rate:

Discount amount = 0.134 x $72.45

Discount amount = $9.72

This means that the discount on the bottle of perfume is $9.72. To find the sale price of the perfume, we can subtract this amount from the original price:

Sale price = $72.45 - $9.72

Sale price = $62.73

Therefore, the sale price of the bottle of perfume is $62.73. This is the amount that customers would need to pay during the clearance sale, after the 13.4% discount has been applied.

The equation to find the area of the community garden as a function of the number x of households that reserve a plot is A(x) = 20x² + 200x.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

(a) Given that,

A community garden is being planned.

Each household that joins the project will have a rectangular plot that is 20 feet wide.

If the number of households is x,

Length of the plot = 20x

The town has already permitted the plots to extend 10 feet into the field, and promised another foot for every household that reserves a plot.

Width of the plot = x + 10

Area of a rectangle = Length × Width

                                = 20x (x + 10)

                                = 20x² + 200x

A(x) = 20x² + 200x

(b) If area cannot exceed  4000 square feet,

20x² + 200x ≤ 4000

20x² + 200x - 4000 ≤ 0

Dividing throughout by 20,

x² + 10x - 200 ≤ 0

Factorizing,

(x - 10) (x + 20) ≤ 0

x ≤ 10 or x ≤ -20, which is not possible.

Hence x ≤ 10.

Maximum number of plots is 10.

(c) If the maximum number of plot is used, Area of the garden = 4000 feet²

Area of each plot = 4000 / 10 = 400 feet²

Length and width of the plot = 20 feet

She need 111 square feet to plant wildflower seeds.

The remaining area of the plot = 400 - 111 = 289 feet²

17² = 289

So the width of the border = 20 - 17 = 3 feet

Hence the values are found.

Answer:

Brenda is not correct.

Step-by-step explanation:

Brenda's equation for the new position of the fish in relation to sea level is:

2 times 8 + (negative 320) = 16 - 320 = -304

This means that the fish has descended 2 feet per second for 8 seconds, which is a total descent of 16 feet, and is now at a depth of -304 feet in relation to sea level.

Therefore, Brenda's equation is not correct. The correct equation should be:

new position = initial position - descent

where "initial position" is the starting position of the fish (which is -320 feet in this case), and "descent" is the total distance the fish has descended (which is 2 feet per second x 8 seconds = 16 feet in this case).

Using this formula, we get:

new position = -320 - 16 = -336

So the new position of the fish in relation to sea level is -336 feet, not 336 feet as Brenda's equation suggests.

Therefore, Brenda is not correct.

If a company chooses to grow at its sustainable growth rate (SGR), which involves increasing both retained earnings and debt, the company's weighted average cost of capital (WACC) may be affected in several ways:

Cost of Debt: When a company increases its debt, it may result in an increase in the cost of debt, which is one of the components of WACC. This is because creditors may require a higher rate of return to compensate for the increased risk associated with a higher level of debt.

Cost of Equity: If a company's retained earnings are used to fund growth, the cost of equity may remain unchanged or even decrease if the growth is expected to result in higher earnings and a higher stock price. However, if the company's growth is not expected to generate higher earnings, the cost of equity may increase.

Capital structure: The increase in debt may also result in a change in the company's capital structure. As the proportion of debt in the company's capital structure increases, the WACC may also increase, because debt is generally considered to be a riskier source of financing than equity.

Overall, the impact of a company's decision to grow at its SGR on WACC will depend on the specifics of the company's growth plan, as well as the risk associated with the plan. In general, increasing both retained earnings and debt may increase the company's cost of capital, which would lead to a higher WACC.

In other words, when x is equal to -3, the y-value of the line is 19. This is how you get the value of 19.

Value is the worth of something in terms of its usefulness or importance. It can also refer to the moral principles and beliefs that guide how a person or group of people live. Values change over time, depending on the culture and context. For example, respect for one's elders might be a value in one culture, while in another it might be more important to be self-reliant. Value is also used in economics to refer to the worth of a good or service in terms of money.

The answer lies in the formula for the equation of a line: y = mx + b, where m is the slope, x is the input value, and b is the y-intercept.

In this case, m is 16 and x is -3, so when you plug those values into the equation, you get y = 16(-3) + b. To solve for b, we need to subtract 16(-3) from both sides of the equation, which gives us b = 19. Therefore, the y-intercept of the line is 19.

Suppose, Melissa makes deposits for 10 years, the total amount of deposited money in 10 years will be $61,070.14 by using geometric series.

A savings account is a type of bank account that is designed to help people save money. When you deposit money into a savings account, the bank pays you interest on your balance, which means that your money can grow over time.

To find the sum Sn of a geometric series of n terms, we can use the formula:

Sn = a(1 - [tex]r^{n}[/tex]) / (1 - r)

where a is the first term, r is the common ratio, and n is the number of terms.

In this case, the first term is $1,000, and the common ratio is 1.02 (since each subsequent deposit is 2 percent greater than the previous deposit). So we can use: a = 1000 and r = 1.02

To find the number of terms, we need to know how many years Melissa plans to make deposits. Let's say she plans to make deposits for 10 years. Then we have: n = 10

Now we can use the formula to find the sum Sn:

Sn = 1000(1 - [tex]1.02^{10}[/tex]) / (1 - 1.02)

Sn = 1000(1 - 1.221402758) / (-0.02)

Sn = 61070.138

Suppose that Z has a standard normal distribution with a mean of 0 and standard deviation of 1, the probability that z is more than 0.87 is 0.1949 which is an approximate of 0.195.

Probability refers to the likelihood that something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes such as how likely they are. The analysis of events governed by probability is called statistics.

To find the probability that z is more than 0.87 when z follows a standard normal distribution with mean 0 and standard deviation 1, we can use the standard normal distribution table or calculator.

Using the table, we can look up the area under the standard normal distribution curve to the right of z = 0.87. The table shows that the area to the right of z = 0.87 is 0.1949.

Therefore, the probability that z is more than 0.87 is 0.1949 or approximately 0.195 (rounded to three decimal places).
