The number of plants Ethan has are 5.

Two or more expressions with an Equal sign is called as Equation.

Let x be the number of plants Ethan has.

Ethan uses 3.5 ounces of water for each plant, so he will use a total of 3.5p ounces of water.

If he starts with 32 ounces of water and ends up with 14.5 ounces

Total of 32 - 14.5 = 17.5 ounces of water.

As given the amount of water used is equal to the amount of water per plant times the number of plants:

3.5x = 17.5

Divide both sides by 3.5

x=5

Hence, , Ethan has 5 plants.

The function is f(x) = 15x + 25 and you would have 6 services if you were charged $25

We know that the hair salon charges a fixed rate of $25.00 for a haircut and then an additional $15 for any other services, therefore:

Let x = number of services, then we can obtain the function as:

f(x) = 15x + 25 (function)

when we further solve the function, we get the answer for how many services one would have if we were charged $25,

f(x) = 15x + 25

115 = 15x + 25

90 = 15x

6 = x

Now, we know that the function is f(x) = 15x + 25 and you would have 6 services if you were charged $25

Answer:

5/2y - 8

Step-by-step explanation:

Step 1: Add -7 to both sides.

2x+7+−7=5y−9+−72x=5y−16

Step 2: Divide both sides by 2.

2x2=5y−162x=52y−8

Answer:

too lazy to do the math but yk

Step-by-step explanation:

ok so first you wanna make sure you isolate variables, to find x you get

2x+7=5y-9

2x=5y-2

x=(5y-2)/2

plug that into the equation, then you get the y value, which you can put into the equation again (by equation i mean 2x+7=5y-9)

then you have both x and y

The arithmetic series has a first term 'a' and a common difference 'd'. The sum of the first 31 terms is 310. Part (a) requires showing that 'a + 15d = 10'.

To find the sum of an arithmetic series, we use the formula Sn = (n/2)(2a + (n-1)d), where Sn is the sum of the first 'n' terms. Given that Sn = 310 and n = 31, we can substitute these values into the formula. Simplifying the equation, we get 310 = 31a + 465d.

To show that 'a + 15d = 10', we need to find the values of 'a' and 'd'. By solving the system of equations formed by the two equations, 310 = 31a + 465d and a + 15d = 10, we can find the values that satisfy both equations.

The solution to the system of equations is a = 10 and d = -1. Therefore, substituting these values into 'a + 15d', we get 10 + 15(-1) = 10 - 15 = -5. However, this contradicts the equation 'a + 15d = 10' stated in part (a). Hence, there might be an error or missing information in the question as the given equation cannot be satisfied.

The answer is , the conditional probability that an even-numbered card is picked given that the 2 is picked is 1/2 or 0.5.

The conditional probability that an even-numbered card is picked given that the 2 is picked can be calculated using the formula for conditional probability.

Let's assume there are 52 cards in the deck, with half of them being even-numbered (26 cards) and 4 of them being twos (2 of which are even-numbered).

To find the conditional probability, we need to divide the number of favorable outcomes (even-numbered cards that are twos) by the total number of possible outcomes (all twos).

Therefore, the conditional probability can be calculated as:

Conditional Probability = Number of favorable outcomes / Number of possible outcomes

Conditional Probability = 2 / 4

Simplifying the fraction, we get:

Conditional Probability = 1/2

So, the conditional probability that an even-numbered card is picked given that the 2 is picked is 1/2 or 0.5.

2. 3x - 2 = -20

3. 3x = -18

4. × = -6

Answer:

The first one is 3x-2=-20. So the - 2 will cross the equal sign making it positive so it will be 3x = -20+2 given you 3x = - 18. You will divide it by 3 given u - 6. So all of them x= - 6

The inverse of a function can be found by swapping the numbers in each ordered pair of the function.

When you have a function with ordered pairs, the inverse of that function can be found by reversing the order of the numbers within each pair. In other words, if you have a function f(x) with ordered pairs (a, b), the inverse function, f^ (-1) (x), will have ordered pairs (b, a). This process essentially switches the input and output values of the original function.

To find the inverse of a function, simply swap the numbers in each ordered pair, resulting in the ordered pairs for the inverse function.

The lighthouse keeper should land approximately 3 miles from the point on the shore nearest to the lighthouse in order to make the fastest possible time to the restaurant.

To determine the fastest possible time for the lighthouse keeper to reach the restaurant, we need to calculate the time it takes for him to row to the shore and then walk to the restaurant. The key is to minimize the total time taken.

Let's denote the distance from the landing point to the restaurant as x miles. The time taken to row to the shore can be calculated as 7 miles divided by the rowing speed of 2.7 mph, which is approximately 2.59 hours.

The time taken to walk from the landing point to the restaurant can be calculated as (14 + x) miles divided by the walking speed of 4 mph.

To minimize the total time, we need to find the value of x that minimizes the sum of the rowing time and the walking time. So, we can set up the equation:

Total time = 2.59 hours + (14 + x) miles / 4 mph

To find the value of x that minimizes the total time, we can take the derivative of the equation with respect to x, set it equal to zero, and solve for x.

However, given that we are asked to round the answer to the nearest whole number, we can simplify the problem by considering the value of x that yields the smallest whole number total time.

By trying different values of x, we can find the value that minimizes the total time.

When x = 0, the total time is 2.59 + 14 / 4 = 6.59 hours.

When x = 1, the total time is 2.59 + 15 / 4 = 6.84 hours.

When x = 2, the total time is 2.59 + 16 / 4 = 7.09 hours.

Continuing this process, we find that the smallest whole number total time occurs when x = 3.

Therefore, the lighthouse keeper should land approximately 3 miles from the point on the shore nearest to the lighthouse in order to make the fastest possible time to the restaurant.

According to the given statement , the value of "b" in the equation cos(22.6°) = b/13 is approximately 12.

To solve for "b" in the equation cos(22.6°) = b/13, we can use trigonometric functions.

Step 1:

Rewrite the equation as cos(22.6°) = b/13.

Step 2:

Multiply both sides of the equation by 13 to isolate "b". This gives us:

b = 13 * cos(22.6°).

Step 3:

Use a calculator to find the cosine of 22.6°. The value of cos(22.6°) is approximately 0.9239.

Step 4:

Substitute this value back into the equation to find "b". b = 13 * 0.9239.

Step 5:

Calculate the value of "b" by multiplying 13 by 0.9239. The result is approximately 11.999.

Step 6:

Round the value of "b" to the nearest whole number. Since 11.999 is closer to 12, we round up to 12.

Therefore, the value of "b" in the equation cos(22.6°) = b/13 is approximately 12.

If you take a flight from miami to orlando with a flight length that follows a uniform distribution between 35 and 49 minutes.The expected flight time is 42 minutes.

Since the flight length follows a uniform distribution between 35 and 49 minutes, the probability density function (PDF) of the flight length is given by:

f(x) = 1 / (49 - 35) = 1/14, for 35 <= x <= 49

and f(x) = 0 otherwise

The expected value of the flight length is then given by the following integral:

E[X] = ∫x*f(x)dx, for x from 35 to 49

Evaluating the integral, we get:

E[X] = ∫35^49 x*(1/14)dx = (1/14) * [x^2/2]35^49

= (1/14) * [(49^2 - 35^2)/2] = 42 minutes

The equation of line given in the graph is, y = -4/3x.

What is equation of line?

How to calculate the equation of a line starting from two points:

The slope formula can be used to determine the slope.

The y-intercept (b) can be calculated using the slope and one of the points.

When you have the values for m and b, you can use them to solve for the line's equation in the slope-intercept form (y = mx + b).

The given line passes through the points (0, 0) and (3, -4)

So, the slope of the line is,

\(m = \frac{y_2-y_1}{x_2-x_1} = \frac{-4-0}{3-0} = -\frac{4}{3}\)

Now y - intercept is the point where line crosses the y - axis.

Line crosses the x - axis at (0, 0)

Hence, the y - intercept is b = 0.

Plug m = -4/3 and b = 0 in equation y = mx + b

⇒  y = -4/3x + 0

    y = -4/3x

Hence, the equation of line given in the graph is, y = -4/3x.
