Final answer:

The missing data values 'a' and 'c' are determined by recognizing the linear pattern in the table, giving an 'a' value of 6 and a 'c' value of 14, which corresponds to answer choice B.

Explanation:

To determine the missing data values for a linear function, we need to identify the pattern in the given data points. We are given the data points (1, 2), (2, 4), and told that the function is linear. The change in the y-values as x increases by 1, is a consistent +2 (from 2 to 4 as x goes from 1 to 2).

To find the value of 'a' when x = 3, we add 2 to the previous y-value of 4 (at x = 2), resulting in an 'a' value of 6. To find the value of 'c' when x = 7, we add 2 repeatedly for each increase in x, which is 4 steps away from x = 3, resulting in a 'c' value of 6 + 2*4 = 14.

The missing data values 'a' and 'c' are 6 and 14, respectively, which corresponds to choice B.

Answer:

Step-by-step explanation:

Let, the speed of the airplane is x miles/hour and the wind is w miles/hour.

With the wind, the speed will be (x + w) miles/hour  and against the wind, the speed will be (x - w) miles/hour.

As per the given question, [tex]3.6(x + w) = 1800\\4(x - w) = 1800\\(x - w) = 450[/tex]or, w = x - 450.

Now, [tex]3.6(x + w) = 1800\\2x -450 = 500\\2x = 950\\x = 475[/tex].

Thus, w = 475 - 450 = 25.

Answer:

D. an applied force.

Step-by-step explanation:just did it

Answer:

an applied force.

Step-by-step explanation:

An applied force is a force that occurs by pushing or pulling.

An applied force is a contact force because it requires contact between the person or object pushing or pulling and the object being pushed or pulled.

To find the measure of each angle, we can set up an equation and solve it for x, which represents one of the angles. The other angle can be calculated by subtracting x from 90. The answers are x = 63.6° and 90 - 63.6 = 26.4°.

To solve this problem, we need to set up an equation based on the given information. Let x be the measure of one angle, and since the angles are complementary, the other angle will be 90 - x. According to the problem, x is 37.2° more than 90 - x. This can be written as the equation x = 90 - x + 37.2. Solving this equation, we find that x = 63.6°. Therefore, one angle measures 63.6° and the other angle measures 90 - 63.6 = 26.4°.

Answer:

11/16

Step-by-step explanation:

First get common denominators

1/4*4/4=4/16

15/16-4/16=11/16

11/16 is the answer

Final answer:

The difference between 15/16 and 1/4 is 11/16.

Explanation:

To find the difference between two fractions, we need to have a common denominator. In this case, the common denominator is 16.

Converting 1/4 into a fraction with a denominator of 16, we get 4/16.

Now we can subtract the two fractions: 15/16 - 4/16 = 11/16.

Therefore, the difference between 15/16 and 1/4 is 11/16.

Answer:

70° and 20°

Step-by-step explanation:

let x be the measure of one angle then x + 50 is the measure of the other angle, thus

x + 50 + x = 90

2x + 50 = 90 ( subtract 50 from both sides )

2x = 40 ( divide both sides by 2 )

x = 20

The smallest angle is 20° and the other angle is 20 + 50 = 70°

Answer:

5 times

Step-by-step explanation:

First, we need to read the change in price in 2000 and 2007, from the graph.

So, the change in price in 2000 was $0.14 and in 2007 it was $0.71.

Now, we do the same thing we always do when comparing two values - we divide them. So:

0.71 / 0.14 = 5.07

Of course, we could multiply these values with 100, in order to avoid decimal numbers. Then we would get:

71 / 14 = 5.07

We could also divide this in the form of fractions:

71/100 / 14/100 = 5.07

There are several ways we could divide rational numbers, but the result will always be the same.

Change in price in 2007 was around 5 times greater than the change in 2000.

Answer:

y = -1/3x + 2

Step-by-step explanation:

The slopes of perpendicular lines are negative reciprocals.

The line y = 3x - 2 has slope 3.

The perpendicular line has slope -1/3.

Now we find the equation of the line that has slope -1/3 and passes through (-9, 5).

y = mx + b

y = -1/3x + b

5 = (-1/3)(-9) + b

5 = 3 + b

b = 2

The equation of the perpendicular is

y = -1/3x + 2

Answer:

7 in each folder for a total of 49 pages. 7x7=49

Step-by-step explanation:

You may put a number that is a multiple of 7 which divides in to seven folders pages evenly.

Final answer:

To determine the number of pages per folder, divide the total number of pages, which is 292,992, by the number of folders, which is seven. Each folder contains 41,856 pages.

Explanation:

The student has a total of 44,800mm shelf width, which converts to 292,992 pages at a rate of 6.54 pages/mm. To find out how many pages need to go into each of the seven folders, one would simply divide the total number of pages by the number of folders.

The calculation goes as follows:

Total pages / Number of folders = Pages per folder

292,992 pages / 7 folders = 41,856 pages per folder.

Each folder would therefore contain 41,856 pages.

The difference in mass between Earth and Venus is 1.10 times 10²⁴ kg.

The question asks for the difference in mass between Venus and Earth. To find this, we subtract the mass of Venus from the mass of Earth. The calculation goes as follows:

Mass of Earth = 5.97 times 10²⁴ kg

Mass of Venus = 4.87 times 10²⁴ kg

Difference = Mass of Earth - Mass of Venus

Difference = (5.97 times 10²⁴) - (4.87 times 10²⁴) = 1.10 times 10²⁴ kg

So, the difference in mass between Earth and Venus is 1.10 times 10²⁴ kg.

Answer:

D. [tex]y=-0.927x+13.634[/tex]

Step-by-step explanation:

We graph the points on the graph. The graph is attached.

Let us take two points (1, 14) and (15, 1), and calculate the slope [tex]m[/tex]between them (we choose these points because the line passing through them will be the best fit for all points)

[tex]m=\frac{14-1}{1-15} =\frac{13}{-14} =-0.9286[/tex]

Thus we have the equation

[tex]y=-0.9286x+b[/tex]

Let us now calculate [tex]b[/tex] from the point [tex](1,14)[/tex]

[tex]14=-0.9286(1)+b[/tex]

[tex]b=14.9286[/tex]

So the equation we get is

[tex]y=-0.9286x+14.9286[/tex]

Let us now turn to the choices given and see which choice is closest to our equation: we see that choice D. [tex]y=-0.927x+13.634[/tex] is the closest one, so we pick it.

The question simply means how many pizzas are sold per coupon. The equation gives us 3.4x where x is the number of coupons issued. With each coupon issued 3.4 pizzas are sold.

For each additional coupon issued, 3.4 more pizzas are sold according to the linear model y = 3.4x + 43.

The student's question pertains to the interpretation of a linear equation as it relates to a scatter plot of data on pizzas sold versus coupons issued.

The given equation is y = 3.4x + 43, which is a linear model describing this relationship.

In such a linear model, the coefficient of x (which is 3.4 in this case) represents the slope of the line and indicates the rate of change.

In other words, it tells us how many more pizzas are sold for each additional coupon issued.

Therefore, for each additional coupon issued, 3.4 more pizzas are sold according to this model.

Answer:

B, C, and D

Step-by-step explanation:

By doing 5÷8 = .625 you know that Hang can read .625 of a page per minute.

You can do this for the rest of the people finding that Kira reads .5 page per minute which is a slower/ smaller ratio, Joe rate is .66, Quon's ratio is .71 and Lulus rate is .76, the only rate that is smaller than Hangs is Kira,s, leaving you with Joe, Quon, and Lulu to be your answer

Joe, Quon, and Lulu have a greater ratio of pages read to minutes than Hang. Their respective ratios are 0.6667, 0.714, and 0.769, each higher than Hang's ratio of 0.625.

Let's determine who has a greater ratio of pages read to minutes than Hang.

Hang's ratio is 5:8 or 5/8 = 0.625.

ratio = 2/4 = 0.5 (less than 0.625)

    2. Joe: 6 pages in 9 minutes,

ratio = 6/9 = 0.6667 (greater than 0.625)

    3. Quon: 5 pages in 7 minutes,

ratio = 5/7 ≈ 0.714 (greater than 0.625)

    4. Lulu: 10 pages in 13 minutes,

ratio = 10/13 ≈ 0.769 (greater than 0.625)

So, Joe, Quon, and Lulu have a greater ratio of pages read to minutes than Hang.
