3 c ≈ how many mL? Round to the nearest hundredth if necessary.

Answer:

162/5 hours.

Step-by-step explanation:

Let's call the normal depth of the river "D". Since 2/3 of the way to go back to normal is still flooded, the current depth of the water is D + 2/3D = 5/3D.

The flood waters recede at a rate of 1/9 the flood level per hour, so the change in water level each hour is -1/9 * 5/3D = -5/27D.

To find the number of hours it takes to go from the current depth (5/3D) to the normal depth (D), we need to divide the change in depth (-5/27D) by the change in depth per hour (-5/27D): (5/3D - D) / (-5/27D) = (5/3D - D) / (-5/27D) = -(5/3D - D) / (5/27D) = (2/3D) / (5/27D).

This can be simplified to 2/3 * 27/5 = 162/5 hours. The answer is 162/5 hours.

Answer: Since the flood waters still have 2/3 of the way to go back down to reach the normal level, it means that 1/3 of the flood level has already receded.

If the flood level recedes at a rate of 1/9 the flood level per hour, then it will take 1/9 * 1 hour = 1 hour to recede 1/9 of the flood level.

Therefore, to recede 2/3 of the flood level, it will take 2/3 * 1/9 hours = 2/27 hours.

Since there are 60 minutes in 1 hour, the time it takes for the flood waters to reach the normal level in minutes is: 2/27 hours * 60 minutes/hour = 20 minutes.

Therefore, it will take 20 more minutes for the water to reach its normal depth.

The slope-intercept form of the function described by this table?

x 0 1 2 3

y 3 8 13 18. is y = 5x + 3

The slope-intercept form of a linear equation is given by y = mx + b, where m is the slope of the line and b is the y-intercept. To find the equation that fits the table, we can use the two points (0, 3) and (1, 8) to calculate the slope and y-intercept.

First, calculate the slope:

m = (8 - 3) / (1 - 0) = 5

Next, use the point-slope form of a line to find the y-intercept:

y - 3 = 5(x - 0)

Expanding the right-hand side:

y - 3 = 5x

Adding 3 to both sides:

y = 5x + 3

So, the slope-intercept form of the function described by the table is:

y = 5x + 3

The number of red jelly beans and blue jelly beans are 15 and 40 respectively.

Billy bought a bag of jelly beans from the store. Billy counted the jelly beans when he got home and counted a total of 55. The bag contained red and blue jelly beans. The number of blue jelly beans was 5 less than three times the number of red jelly beans.

Therefore, let's find the jelly beans of each colour.

Using equation,

let

x = number of blue jelly beans

y = number of red jelly beans

Therefore,

x + y = 55

x = 3y - 5

Therefore,

x + y = 55

-x + 3y = 5

add the equations

4y = 60

y = 60 / 4

y = 15

x = 55 - 15

The solution to the equation 3 / 5x-2 = 2 / 3x-1 is x = 1.

Given the equation in the question;

3 / 5x-2 = 2 / 3x-1

To solve for x, cross multiply the equation

3 / 5x-2 = 2 / 3x-1

3( 3x - 1 ) = 2( 5x - 2 )

Apply distributive property

3( 3x - 1 ) = 2( 5x - 2 )

3×3x + 3×-1 = 2×5x + 2×-2

9x - 3 = 10x - 4

Subtract 10x from both sides

9x - 10x - 3 = 10x - 10x - 4

9x - 10x - 3 = - 4

Add 3 to both sides

9x - 10x - 3 + 3 = - 4 + 3

9x - 10x  = - 4 + 3

The linear function that predicts the number of cars that will be sold at a price of x dollars is y = -0.05x + 11580.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

To determine the linear function that predicts the number of cars sold we need to find the slope of the equation.

The two coordinated given are:

(x1, y1) = (52000, 8980)

(x2, y2) = (57000, 8730)

The slope of the equation is given by:

m = (y2 - y1) / (x2 - x1)

m = (8730 - 8980) / (57000 - 52000)

m = - 0.05

Substituting the value of the coordinates and slope in the point-slope form we have:

y - y1 = m (x - x1)

y - 8980 = -0.05(x - 52000)

y - 8980 = -0.05x + 2600

y = -0.05x + 11580

Hence, the linear function that predicts the number of cars that will be sold at a price of x dollars is y = -0.05x + 11580.

is continuous at  x = 36,

In mathematics, The function is called as continuous at the particular value of x,  if right hand limit, left hand limit and the value of function at x all are equal.

RHL   = LHL  = F(x)

Limit exist and continuous

Given that,

F(x)  =   (x√x)/(x - 6)²

To check whether it is continuous at x = 36

First taking LHL,

[tex]\lim_{h \to \00}[/tex]    [(36-h)√(36-h)]/((36-h) - 6)²

[tex]\lim_{h \to \00}[/tex]  [(36-0)√(36-0)]/((36-0) - 6)²

⇒   (36 x 6)/30²

⇒    6/25

Now, taking RHL

[tex]\lim_{h \to \00}[/tex]    [(36+h)√(36+h)]/((36+h) - 6)²

[tex]\lim_{h \to \00}[/tex]  [(36+0)√(36+0)]/((36+0) - 6)²

⇒   (36 x 6)/30²

⇒    6/25

The value at x = 36

F(-1)  =  [(36)√(36)]/((36) - 6)²

⇒   (36 x 6)/30²

The area of the lawn that will be watered by the sprinkler is 191.1 square feet, rounded to the nearest tenth.

Area is a measurement of the size of a two-dimensional surface, such as a square, rectangle, or circle. It is calculated by multiplying the length of the surface by its width. Area can also be measured in terms of square units, such as square feet or square meters. Area is an important concept in mathematics and is used to measure the size of shapes and objects. It is also used to find the total area of a group of shapes.

To calculate the area, use the formula A = r2θ, where A is the area, r is the radius, and θ is the central angle in radians. In this scenario, the radius is 10 ft and the central angle is 30°, or π/6 radians. Plugging these numbers into the formula, we get A = (10 ft)2(π/6 radians), or 191.1 square feet.

Answer:

3.2 miles

Step-by-step explanation:

To approximate the height of the mountain, we need to use the tangent function in trigonometry. We have two angles of elevation and the distance between the observer and the mountain, which we can use to create a right triangle.

Let h be the height of the mountain and d be the distance from the observer to the foot of the mountain.

At the first observation, we have:

tan(3.5°) = h/d

And at the second observation, when the observer is 11 miles closer to the mountain:

tan(9°) = h/(d-11)

Dividing the two equations, we have:

tan(9°) / tan(3.5°) = h/(d-11) / h/d

Solving for h, we have:

h = (d * tan(9°)) / (tan(3.5°) + 1)

We don't have an exact value for d, so we can use an estimate based on the difference in distance between the two observations.

Since d-11 = 11 miles, we have:

d = 11 * 2 = 22 miles

Using this estimate and the given angles, we can approximate the height of the mountain:

h = (22 * tan(9°)) / (tan(3.5°) + 1) = (22 * 0.156434465) / (0.066012183 + 1)

= 22 * 0.156434465 / 1.066012183 = 22 * 0.146838446 = 3.23 miles

The height of the mountain is approximately 3.2 miles to one decimal place.

The triangle above is a 45-45-90 triangle since it has two 45-degree angles. For this explanation, let a and b represent the legs of a right triangle and c be the hypotenuse. In this type of triangle, the legs are equal, so a=b. The hypotenuse is [tex]\sqrt{2}[/tex] times the leg length. So, c = a√2.

Finding x and y

In this problem, x is one of the legs. This means that x = 2 since 2 is the length of the leg. The y-value represents the hypotenuse, so we can multiply the leg by √2. Thus, y = 2√2.

R and S are points on the number line. If RS= 11 and S lies at 5, where could R be located 16 or -6.

A number line is a visual representation of numbers arranged in a continuous sequence along a straight line. It is used to represent the real numbers and to help visualize relative sizes and order of numbers. The numbers on a number line are placed at equal intervals, and the distance between two numbers represents the magnitude of the difference between them.

A typical number line starts from a specific number on the left, such as zero, and extends to the right, with positive numbers increasing as you move to the right and negative numbers decreasing as you move to the left. Points on the number line correspond to specific numbers, and the position of a point on the line represents the value of that number.

The number line is a useful tool in mathematics for solving problems, such as determining the solution to an equation, estimating the value of a decimal or fraction, or visualizing the magnitude of a negative or positive number. It is also used in geometry to represent the positions of points and to understand concepts such as distance and midpoint.

If S lies at 5 on the number line and RS = 11, then R could be located at either 5 + 11 = 16 or 5 - 11 = -6. So, R could be at either 16 or -6 on the number line.
