Answer:

Density = Mass / Volume

3 g/cm^3 = 25 g / Volume

Volume = 25 g / 3 g/cm^3 = 8.33 cm^3

Round to two decimal places: 8.33 cm^3

Therefore, the volume of the block of wood is 8.33 cm^3.

Answer:

520 cubic centimeters (cm^3)

Step-by-step explanation:

volume = length * width * height

length = 13

width = 5

height = 4 + 4, so height = 8

volume = (13) * (5) * (8)

volume = 520 units

Since the given measurements are in centimeters and the answer is the volume of the prism, the answer must be in cubic centimeters

So, the final answer is 520 cubic centimeters (cm^3)

Answer:

D. If M does not divide AB into two congruent segments, then M is not the midpoint of AB.

Step-by-step explanation:

A conditional statement is one that include 'if'. Thus it is also referred to as an 'if' statement.

Given a conditional statement:

If M is the midpoint of AB, then M divides AB into two congruent segments.

The converse of the given statement is done by interchanging the two parts of it. So that we have:

If M divides AB into two congruent segments, then M is the midpoint of AB.

Then, the inverse can be obtained by getting the negative of both parts of the converse. Therefore, the inverse is:

If M does not divide AB into two congruent segments, then M is not the midpoint of AB.

The correct option is D.

Answer: b = 14.

Step-by-step explanation:

We have the function:

f(x) = x^2 + b*x - 21

The minimum of a quadratic function will be at the vertex, and the vertex is at the value of x such that:

f'(x) = 2*x + b = 0

then the vertex is at:

x = -b/2

Then the minimum of the function f(x) will be:

f(-b/2) = (-b/2)^2 + b*(-b/2) - 21

and we know that the minimum value is -70, then:

f(-b/2) = -70 = (b^2)/4 - (b^2)/2 - 21

Now we need to solve this equation for b.

-70 = (b^2)/4 - (b^2)/2 - 21

-70 = -(b^2)/4 - 21

-70 + 21 = -(b^2)/4

49 = (b^2)/4

49*4 = b^2

196 = b^2

√196 = b = 14

The value of b is 14.

What is an linear equation in math?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included.

The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

The two numbers are 15.75 and 176.3

First we will compare the numbers.

1. A=176.3

2. B=15.75

one's place of A is greater than once place of B.

tens place of A is greater than tens place of B.

Hundred place of A is greater than hundred place of B.

So, A>B

So  we will subtract 15.75 from 176.3.

176.30 -15.75=

176.30     ----A

- 1 5.75     ----B

Hundreths place of A - Hundreths place of B =  0-5=10-5=5

Tenth place of A  - Tenth place of B =12-7=5

ones place of A - ones place of B=5-5=0

Tens place of A - Tens place of B =7-1=6

To solve for the total number of pencils:

Let the total number of pencils be x

Note that every student gets x/44

To represent the fact that some students shared their pencils to others, we state:


8(x/44)/(44-8) = 2

⇒ (8x/44) /36 = 2; multiply both sides by 36

⇒ 8x/44 = 72; collect like terms over the equals sign

⇒ x = 44 x72/8

The coordinates of W(-7, 4) after a reflection in the line y = 9 are (-7, -2).

The line y = 9 represents a horizontal line at y = 9 on the coordinate plane.

To reflect a point across a line, we need to find the same distance between the point and the line on the opposite side.

The line y = 9 is 5 units below the point W(-7, 4), so we need to reflect the point 5 units above the line.

We subtract 5 from the y-coordinate of the point W(-7, 4) to find the new y-coordinate after reflection: 4 - 5 = -1.

The x-coordinate remains the same, so the coordinates of the reflected point are (-7, -1).

However, the reflected point is still below the line y = 9. To bring it above the line, we need to reflect it again.

This time, we add 10 to the y-coordinate of the reflected point: -1 + 10 = 9.

The final coordinates of W(-7, 4) after reflection in the line y = 9 are (-7, -1).

Therefore, the coordinates of W(-7, 4) after a reflection in the line y = 9 are (-7, -1).

i took the quiz :)

Step-by-step explanation:

The two true statements are:

The rule for Pattern B is "multiply by 2."

Each term in Pattern A is one-half the corresponding term in Pattern B.

Here we have two patterns:

First, let's analyze the patterns. For pattern A we can see that we just add 6 to each consecutive term, so this is an arithmetic sequence.

6 + 6 = 12

12 + 6 = 18

18 + 6 = 24

And so on.

For pattern B we multiply each term by 2 to get the next one, so this is a geometric sequence.

2*12 = 24

2*24 = 48

and so on.

Then we already can see that. "The rule for Pattern B is "multiply by 2." Is true

And:

The rule for Pattern A is "multiply by 2." is false.

Finally, let's compare the terms. The first term of B is 12, and the first ter of A is 6, so we can see that the first term of B is two times the first one of A. The second term of B is 24, while the second of A is 12, so again, we can see that the second term of B is two times the second of A.

So we can see a pattern, meaning that the statement: "Each term in Pattern A is one-half the corresponding term in Pattern B."

60 pretzels = 9 minutes

x    pretzels = 60 minutes

60(60)=9x

3600=9x

Divide both sides by 9

x= 400 pretzels

This team can form 400 pretzels in 1 hour

Answer:

this team can form 30 pretzels in 1 hour

Step-by-step explanation:

60 minutes are in a hour, and 60 divided by 9 is 6.6. So that means you would have to use 6. So 9 x 6 equals 54. Now do 5 x 6 and that would equal 30.

The inverse of the function f(x) = 16x² is equal to y = (√x)/4.

In Mathematics, an inverse function simply refers to a type of function that is obtained by reversing the mathematical operation in a given function (f(x)).

In order to determine the inverse of any function, you should swap both the input value (x-value) and output value (y-value) as follows;

f(x) = y = 16x²

x = 16y²

By dividing both sides of the function by 16, we have the following:

y² = x/16

y = √(x/16)

y = (√x)/4

The directional derivative of the function f(x, y) = 7 - (x^2/5) - y^2 at the point (1, 1) in the direction -(-sqrt(2)/2, sqrt(2)/2) is 2√2. The level curve passing through the given point has a parabolic shape, and the direction of the directional derivative at that point is indicated by the direction of steepest ascent.

In conclusion, the value of the directional derivative at the point (1, 1) in the direction -(-sqrt(2)/2, sqrt(2)/2) is 2√2. The level curve through this point is parabolic, and the direction of the directional derivative represents the direction of steepest ascent.

To find the directional derivative, we need to compute the gradient vector ∇f(x, y) = (∂f/∂x, ∂f/∂y). Taking partial derivatives, we get ∂f/∂x = (-2x/5) and ∂f/∂y = -2y. Evaluating these at the point (1, 1), we have ∂f/∂x = -2/5 and ∂f/∂y = -2.

Next, we normalize the direction vector -(-sqrt(2)/2, sqrt(2)/2) to obtain (-1/√2, 1/√2). The directional derivative Df at (1, 1) in the direction (-1/√2, 1/√2) is given by Df = ∇f(x, y) ⋅ (-1/√2, 1/√2), where ⋅ denotes the dot product. Plugging in the values, we have Df = (-2/5, -2) ⋅ (-1/√2, 1/√2) = (-2/5)⋅(-1/√2) + (-2)⋅(1/√2) = 2√2.

The level curve passing through (1, 1) represents the set of points where f(x, y) is constant. Since the graph of f(x, y) is a paraboloid, the level curve will have a parabolic shape. The direction of the directional derivative at the given point is perpendicular to the level curve and represents the direction of steepest ascent.

Therefore, it points away from the center of the paraboloid, indicating the direction in which the function increases most rapidly.

With his average speed of 3mph, Viktor should leave his house by 6:36 am to arrive at the skaring rink on time.

From the case, we know that:

Average speed = 3.0 mph

Distance = 1.2 miles

Arrival time = 7:00 am

Departure time?

Using the average speed concept, we know that average speed can be calculated by dividing the travel distance with the travel time, or it can be formulated as:

Average speed = distance : travel time

3.0 = 1.2 : travel time

travel time = 0.4 hours

After finding the travel time Viktor spend to go from his house to the skating rink, we need to find the departure time for him to arrieve at the skating rink on time. However, we need to convert the travel time into minutes first.

Travel time = 0.4 hours

Travel time = 0.4 x 60 minutes

Travel time = 24 minutes

Arrival time = Departure time + Travel time

7:00 = Departure time + 24 minutes
