Answer:

A question on a test provides this graph

You, however, did not provide the graph.

Please repost the question along with the graph.

The speed is the rate of change of distance with respect to time thus the speed according to the graph will be 60 miles per hour so Anna interchanged distance and time by mistake.

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

For example the speed 3meter/second.

As per the given graph.

Speed = distance traveled /  time taken

Speed = 60 / 1 miles per hour

But Anna says 1/60 this means Anna took time taken / distance traveled instant of distance traveled /  time taken.

Hence "The speed is the rate of change of distance with respect to time thus the speed according to the graph will be 60 miles per hour so Anna interchanged distance and time by mistake".

Answer:

To find the average price of all 4 pies, we have to know the price of all 4 pies. You have only given the price of 3 of the pies, so there is no way to figure the average. The best you can do in this case is say that the peach pie costs (6 + 7 + 11 + X) / 4 dollars, where X is the cost of the peach pie.

I think you meant to say that the peach pie cost the average of the prices of the other three pies. In which case, it costs (6 + 11 + 7) / 3, or $8.00.

Step-by-step explanation:

The acres of land she will need to produce 24 tons of nuts is 28 acres.

The farmer produces 9 tons of nuts from 10 1 / 2 acres of land.

The acres of land needed to produce 24 tons of nuts can be calculated below:

9 tons of nuts needs 10 1 / 2(21 / 2) acres of land

24 tons of nuts will need ? acres of land

cross multiply

Acres of land needed = 24 × 21 / 2 / 9

Acres of land needed = 252 / 9

Acres of land needed = 28 acres

Step-by-step explanation:

In similar triangles, corresponding sides are proportional. This lets us write an equation involving x. Sides adjacent are proportional to sides opposite the vertical angle.

Answer:

Step-by-step explanation:

Let x and y represent the prices of adult and student tickets, respectively. Then the revenue equations are ...

  13x +9y = 138

  3x +14y = 163

Solving this using a graphing calculator, we find (x, y) = (3, 11).

The price of an adult ticket is $3; the price of a student ticket is $11.

_____

Algebraic solution

When the numbers are "messy," as they are here, I like to use the "cross-multiplication method" for solution. I find it easier to use the order 1, x, y, rather than the order x, y, 1 as shown in the second attachment. That way, the coefficients are in their original order, with the first coefficient repeated. Note the right-side constant must be subtracted to get the form ax+by+c = 0.

  [tex]\begin{array}{cccc}13&9&-138&13\\3&14&-163&3\end{array}[/tex]

Then we have ...

  1/(13·14 -3·9) = x/(9·(-163) -14·(-138)) = y/((-138)·3 -(-163)·13)

  x = 465/155 = 3 . . . . price of an adult ticket

  y = 1705/155 = 11 . . . price of a student ticket

Using the arrangements formula and the probability concept, it is found that:

The number of possible arrangements of n elements is given by:

[tex]A_n = n![/tex]

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, there are 4 runners, hence, the number of different ways the race can be completed is:

[tex]A_4 = 4! = 24[/tex]

Considering A first and C second, for the third and fourth positions, it is an arrangement of 2 elements, hence:

[tex]A_2 = 2! = 2[/tex]

The probability is:

[tex]p = \frac{2}{24} = \frac{1}{12}[/tex]

[tex]\frac{1}{12}[/tex] probability that A finishes first and C finishes second.

At the height of 2467.2 meters from the earths surface, the air pressure equals 50% of the air pressure at the surface of the Earth.

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is that air pressure may be represented as a function of height (in meters) above the surface of the Earth, as shown below -

P(h) = P[tex]e^{-0.000122h}[/tex]

where {P} is the air pressure at the surface of the Earth, and his the height above the surface of the Earth, measured in meters.

For 50% of the air pressure at the surface of the Earth, we can write -

50P/100 = P[tex]e^{-0.000122h}[/tex]

1P/2 = P[tex]e^{-0.000122h}[/tex]

1/2 =  [tex]e^{-0.000122h}[/tex]

- 0.000122h = log(1/2) = - 0.301

h = - 0.301/- 0.000122

h = 2467.2 meters

Therefore, at the height of 2467.2 meters from the earths surface, the air pressure equals 50% of the air pressure at the surface of the Earth.

Step-by-step explanation:

The 3rd interior angle of the triangle can be written as

The angle above is supplementary to the angle (2x - 2), therefore

a is the first term

d is the common difference

Step-by-step explanation:The cost of an adult ticket to the show is $5.5

The cost of a student ticket to the show is $4.25

A family is purchasing 2 adult tickets and 3 student tickets. This means that the total cost of 2 adult tickets would be

2 × 5.5 = $11

It also means that the total cost of 3 student tickets would be

3 × 4.25 = $12.75

The total cost of 2 adult tickets and 3 student tickets would be

11 + 12.75 = $23.75

If the family pays $25, the exact amount of change they should receive is

25 - 23.75 = $1.25
