So because Howard wants to divide the granola evenly among all of his friends, we have to divide the amount of pounds he has by the number of friends he has.

(3/5) / 4

Dividing by four is the same as multiplying by the reciprocal of 4 which is 1/4.

So (3/5) * (1/4) is 3/20 which is .15 pounds

Transformed shapes contribute to the design of objects by making them more efficient to get the most out of their characteristics.

Architecture is a term to refer to the technique of projecting, designing and building, modifying the human habitat based on the proper use and function of spaces.

Engineering is a term for the use of scientific principles to design and create machines, structures, and other objects.

These two disciplines use modified shapes to design and build objects and structures, that is, they take geometric shapes and make modifications to them to get the most out of an element as needed.

For example, engineers and architects who design and build a house must modify the geometric figures of the square, rectangle and triangle to make their spaces with:

Appropriate amplitude, The most efficient lighting and Their roof is inclined so that on days of rain the water rolls to the sides of the house.

Answer:7

Step-by-step explanation:

100/20 = 5

35/5 = 7

Answer:

y = -x - 1 ;  y = 11x - 25

Step-by-step explanation:

y = x² + x

y-(-3) = m(x-2)

y = x²+x

y + 3 = mx - 2m

y = x² + x

y = mx - 2m - 3

x² + x = mx - 2m - 3

x² + x - mx + 2m + 3 = 0

x² + (1-m)x + 2m + 3 = 0

discriminant = m² + 1 - 2m -4 (2m + 3)

m² + 1 - 2m - 8m  - 12

m² - 10m - 11

the line is tangent so the discriminant must be equal to 0

m² - 10m - 11 = 0
(m-11)(m+1) = 0

m = 11

m = -1

y + 3 = -(x-2)

y+ 3 = -x + 2

y = -x + 2 - 3

y = -x - 1

y + 3 = 11(x-2)

y + 3 = 11x - 22

y = 11x -22 - 3

y = 11x - 25

Answer: 2/5 feet

Step-by-step explanation:

From the question, we are informed that Marty and Adam want to share 8/10 feet of rope, equally.

The amount of rope that each person would get would be calculated by dividing 8/10 by 2. This will be:

= 8/10 ÷ 2

= 8/10 × 1/2

= 8/20

= 2/5

Therefore, each person gets 2/5 feet of rope.

H²=P²+B²

4x (4x+3)(4x-3) is the given expression. Here we can use the formula of special products to multiply the given expression.The formula for special product is (a+b)(a-b)=a²-b² .

Consider a=4x and b=3. Substituting the values in the formula, we get

(a+b)(a-b)=a²-b² (4x+3)(4x-3) = (4x)² - (3)²  = 16x² - 9

The given expression 4x (4x+3)(4x-3) can be simplified as 4x(16x² - 9).The next step is to simplify the given expression. Multiply 4x by 16x² and 4x by -9. We get, 4x(16x²) + 4x(-9) = 64x³ - 36x.

Therefore, 4x (4x+3)(4x-3) simplified is 64x³ - 36x.The expression to be solved is (6x + 7)(x+6). Multiplying the given expression (6x + 7)(x+6), using special product method, we get

(6x + 7)(x+6)=6x(x+6) + 7(x+6)= 6x² + 36x + 7x + 42= 6x² + 43x + 42.

Therefore, (6x + 7)(x+6) = 6x² + 43x + 42.

Answer: 18 dollars

Step-by-step explanation:

Let x be the amount of money each girl recevied. Then, in total, they received 4*x dollars.

We can set up an equation for the information given.

4x - 4*12 = 24

4x - 48 = 24

4x = 72

x = 18

Therefore, each girl received 18 dollars.

Step-by-step explanation:

The property of translations on a coordinate plane, is pretty easy to remember, if you go up, you add to the y, if you go down, subtract from the y

If you go left, subtract from the x, if you go right, add to the x.

Example: State the number of moves the x and y variable in each vertex had to go through and what direction, (-100, 27) to (100,0)

Answer:

The x had to go through 200 moves to the right to add 200 onto the x

The y had to go through 27 moves to the left to subtract 27 from y.

Step-by-step explanation:

The equation of a regression line can be written in the form y = mx + b, where m is the slope of the line and b is the y-intercept. In this case, the slope m is given as 1.885.

The y-intercept b can be found using the formula b = y_mean - m * x_mean, where x_mean and y_mean are the means of the x-coordinates and y-coordinates of the data points, respectively. Plugging in the given values, we get:

b = 12.318 - 1.885 * 3.448 b ≈ 5.819

So the y-value of the y-intercept of the line to three decimal places is approximately 5.819. The correct answer is D. 5.819.

Step-by-step explanation: The solution to this system of equations will be where the two lines on the graph intersect with each other.

Notice that both of them intersect to the left of the y-axis which means our x - coordinate must be negative.

They also intersect above the x-axis so our y-coordinate must be positive.

So the only option with a negative x-coordinate

and a positive y-coordinate is (-1/4, 3/4).

There are 10000 micrometers are in a centimeter.

What is micrometers?

 Micrometers are commonly used to determine the thickness or diameter of microscopic objects such as microorganisms and colloidal particles. The International Bureau of Weights and Measures' symbol for a micrometre is m. The micrometer is a length unit derived from SI that equals 106 metre (SI standard prefix "micro-" = 106) and is equivalent to one millionth of a metre or one thousandth of a millimetre.

Here we know that ,

1 centimeter = 10000 micrometers.

If we want to convert 1 centimeter into micrometer we need to multiply by 10000.

Hence there are 10000 micrometers are in a centimeter.

The probability that a student has a GPA under 2.0 given that he has skipped many classes is 8/11.

From the table we see that,

The student who have a GPA under 2.0 = 80

The student who has skipped many classes = 80 + 25 + 5

The student who has skipped many classes = 110

Hence, the probability that a student has a GPA under 2.0 given that he has skipped many classes = The student who have a GPA under 2.0/The student who has skipped many classes

The probability that a student has a GPA under 2.0 given that he has skipped many classes = 80/110

Based on the formula of the quadratic function y=-x^2+6x-5, we know that its graph is a downward-facing parabola that opens wide, with a vertex at (3,-14), and an axis of symmetry at x=3.

Based on the formula of the quadratic function y=-x^2+6x-5, we can determine several properties of its graph, including its shape, vertex, and axis of symmetry.

First, the negative coefficient of the x-squared term (-1) tells us that the graph will be a downward-facing parabola. The leading coefficient also tells us whether the parabola is narrow or wide. Since the coefficient is -1, the parabola will be wide.

Next, we can find the vertex using the formula:

Vertex = (-b/2a, f(-b/2a))

where a is the coefficient of the x-squared term, b is the coefficient of the x term, and f(x) is the quadratic function. Plugging in the values for our function, we get:

Vertex = (-b/2a, f(-b/2a))

= (-6/(2*-1), f(6/(2*-1)))

= (3, -14)

So the vertex of the parabola is at the point (3,-14).

Finally, we know that the axis of symmetry is a vertical line passing through the vertex. In this case, it is the line x=3.
