Answer:

Number of bags Miranda makes equals:

8

Step-by-step explanation:

Miranda buys 6 pounds of nuts.

She puts 3/4 pound in each bag

Let she makes x bags

then total nuts in x bags=[tex]\dfrac{3}{4}x[/tex]

also total nuts must be equal to 6

i.e. [tex]\dfrac{3}{4}x=6[/tex]

Multiplying both sides by 4, we get

3x=24

Dividing both sides by 3, we get

x=8

Hence, number of bags Miranda makes equals:

8

Final answer:

To calculate the area of the floor in square feet, the dimensions in yards are first converted to feet (1 yard = 3 feet), and then the length and width in feet are multiplied to get the area (15 feet x 12 feet = 180 square feet).

Explanation:

The student is asking about the area of a rectangular floor in square feet when the dimensions given are in yards. To find the area of the floor, we first convert the measures from yards to feet, knowing that 1 yard equals 3 feet. Therefore, the rectangular floor measures 5 yards long (which is 5 x 3 = 15 feet long) and 4 yards wide (which is 4 x 3 = 12 feet wide).

Now we can calculate the area by multiplying the length by the width. The area in square feet is thus 15 feet x 12 feet = 180 square feet.

The vector v = (4, -1) can be written as a linear combination of the vectors u = (2, 2) and w = (2, -3). The coefficients are both 1, which means that v = u + w.

In this problem, we are trying to express the vector v = (4, -1) as a linear combination of the vectors u = (2, 2) and w = (2, -3). A linear combination means that we want to find coefficients a and b such that a*u + b*w = v.

Setting that equation up, we have:
a(2, 2) + b(2, -3) = (4, -1).
This leads to two equations:
2a + 2b = 4 and 2a - 3b = -1.

After solving this system of equations, we find that a = 1 and b = 1. Therefore, the vector v can be written as a linear combination of u and w as v = u + w.

V can be written as v=u+w.

To express v as a linear combination of u and w, we need to find scalars a and b such that:

v = a * u + b * w

Given: u = (2, 2), w = (2, -3), and v = (4, -1)

We can set up the following system of equations based on the components:

2a + 2b = 4 (Equation 1 from x-components)

2a - 3b = -1 (Equation 2 from y-components)

Solving Equation 1 for 'a':

2a + 2b = 4

a + b = 2

a = 2 - b

Substituting 'a' in Equation 2:

2(2 - b) - 3b = -1

4 - 2b - 3b = -1

4 - 5b = -1

-5b = -5

b = 1

Substituting 'b' back into a = 2 - b:

a = 2 - 1

a = 1

Thus, v can be written as:

v = 1 * u + 1 * w

So, v = u + w

The slope of a line that is parallel to the line shown on the graph is -3.

The slope or gradient of a line is a number that describes both the direction X and Y and the steepness of the line. It is the ratio of the vertical change to the horizontal change between any two distinct points on a line.

For the given situation,

The slope of a line from its graph by looking at the rise and run.

The vertical change between two points is called the rise, and the horizontal change is called the run.

One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

Now take points (0,2) and (1,-1)

[tex]Slope = \frac{rise}{run}[/tex]

Line slants down from left to right. So line has a negative slope.

⇒ [tex]Slope =\frac{y2-y1}{x2-x1}[/tex]

⇒ [tex]Slope =\frac{-1-2}{1-0}[/tex]

⇒ [tex]Slope = -3[/tex]  

The slope of the line that is parallel to the given line is same as that of the line.

Hence we can conclude that the slope of a line that is parallel to the line shown on the graph is -3.

Final answer:

The slope of the equation y = 1/4x + 3 is 1/4 and the y-intercept is 3, corresponding to option A: slope: 1/4 ; y-intercept: 3.

Explanation:

To identify the slope and y-intercept of the equation y = 1/4x + 3, we can compare it to the general form of the slope-intercept equation for a line, which is y = mx + b. In this form, m represents the slope of the line, and b represents the y-intercept of the line. Thus, looking at the given equation, the coefficient of x (which is 1/4) is the slope, and the constant term (which is 3) is the y-intercept.

The correct answer is:

Therefore, the answer is option A: slope: 1/4 ; y-intercept: 3

To divide fractions, multiply the first fraction by the reciprocal of the second fraction and simplify if possible.

To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is found by switching the numerator and denominator. So, to divide 5/18 by 2/6, we will multiply 5/18 by 6/2.

First, we cancel out any common factors between the numerators and denominators:

5/18 * 6/2 = (5 * 6)/(18 * 2) = 30/36.

Now, we can simplify 30/36 by finding the greatest common divisor (GCD) of 30 and 36, which is 6.

Dividing both the numerator and denominator of 30/36 by 6, we get the final quotient of 5/6.

Answer:

d. C=0.46(w-5)+9.7

Step-by-step explanation:

the cost of having a package delivered has a base fee of $9.70, that means that independently of the pounds of the package, the cost is always going to be $9.70

Then, there is an additional cost, that just count if the package have more than 5 lbs. Every pound over this 5 lbs, cost $0.46 per pound. So, the additional cost is:

0.46*(w-5)

Where (w-5) are the number of pound that over 5 lbs.

Finally the total cost is the sum of the base cost and the additional cost, that can be written as:

C=0.46*(w-5)+9.7

Answer:

A- The distance that represents 11 billion years is 244.4 meters.

B- Written human history begins 0.2 milimeters far from the end of the timeline.

Step-by-step explanation:

A- We can solve this problem by using crossed multiplication.

4,5 billion years --- 100 meters

11 billion years --- X

11 x 100 / 4,5 = X

X= 244.4

B- Once again, this can be solved using crossed multiplication.

If 4,500,000,000 years are represented in 100 meters, that would be:

4,500,000,000 --- 100 meters

10,000 --- X

10,000 x 100 / 4,500,000,000 = X

X= 0.0002 meters

0.0002 meters are 0.2 milimeters

Answer:  The correct option is

(A) m = 1; (0, 3).

Step-by-step explanation:  We are given to find the slope, m, and the y-intercept of the graphed line.

We know that

the slope of a line passing through the points (a, b) and (c, d) is given by

[tex]m=\dfrac{d-b}{c-a}.[/tex]

From the graph, we note that the line passes through the points (-3, 0) and (-1, 2).

Therefore, the slope of the graphed line will be

[tex]m=\dfrac{2-0}{-1-(3)}=\dfrac{2}{2}=1.[/tex]

Also, at x = 0, the value of the y-coordinate is 3. So, the y-intercept of the line is (0, 3).

Thus, the slope, m = 1  and the y-intercept is (0, 3).

Option (A) is CORRECT.

To determine which is larger between  k(8) - k(7)  and  k(3) - k(2) , compare the specific values. If the graph of  k(t)  is concave upward, studying more hours yields a larger knowledge increase.

To determine which is larger between  k(8) - k(7)  and  k(3) - k(2) , and to understand the concavity of the graph of  k(t) , consider the following:

1. Larger Increase in Knowledge:

  - Evaluate  k(8) - k(7)  and  k(3) - k(2) .

  - If  k(8) - k(7)  is greater, it implies that studying for an additional hour (from 7 to 8 hours) provides a larger increase in knowledge than studying for an hour from 2 to 3 hours.

2. Concavity of the Graph:

  - If  k''(t) > 0  (second derivative is positive), the graph is concave upward.

  - If  k''(t) < 0  (second derivative is negative), the graph is concave downward.

3. Reasoning for Concavity:

  - If the graph is concave upward, it suggests that the rate of knowledge gain is increasing. Studying more hours leads to a larger increase in knowledge.

4. Final Answer:

  - The comparison between  k(8) - k(7)  and  k(3) - k(2)  depends on the specific function  k(t) . As for concavity, if the graph is concave upward, studying more hours yields a larger increase in knowledge.

In summary, compare the specific values  k(8) - k(7)  and  k(3) - k(2)  and analyze the concavity of the graph to determine the relationship between studying hours and knowledge gain.

Question. Let k(t) be a measure of the knowledge you gain by studying for a test for t hours, . Which do u think is larger, k(8)-k(7) or k(3) - k(2) ? is the graph of k concave upward or concave downward? why?
