The equation that can be used to find the sale price ,s, of an oil change would be =s= 0.85 (30). That is option 3.

A sale price of a product is defined as the cost of that product which shows its value in the market or economy.

The oils change at city auto = $30

The percentage of coupon that Mr Allen has = 15% of $30

That is;

= 15/100 × 30

= 450/100

=$ 4.5

= 30-4.5 = $25.5

The sale price = $25.5 which is the same as 0.85 (30) since 100-15 = 85%= 0.85

The inverse of a biconditional statement is not equivalent to the original statement. The inverse statement may have a different meaning or convey a different condition.

The inverse of a biconditional statement involves negating both the "if" and the "only if" parts of the statement. In this case, the inverse of the biconditional statement would be:Inverse of Statement 1: A figure is not a polygon if and only if not all of its sides are line segments.

Now, let's analyze the relationship between Statement 2 and its inverse.

Statement 2: A figure is not a polygon if and only if not all of its sides are line segments.

Inverse of Statement 2: A figure is not a polygon if and only if all of its sides are line segments.

The inverse of Statement 2 is not equivalent to Statement 1. In fact, the inverse of Statement 2 is a different statement altogether. It states that a figure is not a polygon if and only if all of its sides are line segments. This means that if all of the sides of a figure are line segments, then it is not considered a polygon.

In contrast, Statement 1 states that a figure is a polygon if and only if all of its sides are line segments. It affirms the condition for a figure to be considered a polygon, stating that if all of its sides are line segments, then it is indeed a polygon.

With $420, you can buy approximately CAD 541.80. Keep in mind that this is an estimated amount, and actual rates may differ at the time of your transaction.

To determine the amount of Canadian dollars you can buy with $420, we need to use the currency exchange rates. However, since the table containing the rates was not provided, I will use an approximate exchange rate based on recent data. Please note that exchange rates can fluctuate, so the actual amount may vary.

Let's assume the approximate exchange rate is 1 USD = 1.29 CAD. To calculate the amount of Canadian dollars you can buy, multiply the amount of US dollars by the exchange rate:

$420 * 1.29 CAD/USD = CAD 541.80.

With $420, you can buy approximately CAD 541.80. Keep in mind that this is an estimated amount, and actual rates may differ at the time of your transaction. It's always a good idea to check with a reliable currency exchange service or bank to get the most accurate rate and ensure you have the correct amount of Canadian dollars for your trip.

The answers to the questions involving trigonometry are: 90, BC/AB ÷ BC/AB = 1, g = 6.5, <I = 62 degrees, h= 13.8, 12.0, x = 6.8, x = 66.4, 160.6, The pole = 6.7

Trigonometric ratios are special measurements of a right triangle, defined as the ratios of the sides of a right-angled triangle.  There are three common trigonometric ratios: sine, cosine, and tangent

For page 3 question 3,

a) <A + <B = 90 since <C = right angle

b) SinA = BC/AB and CosB = BC/AB

The ratio of the two angles BC/AB ÷ BC/AB = 1

I notice that the ratio of sinA and cosB gives 1

b) The ratio of CosA and SinB will give

BC/AB ÷ BC/AB

= BC/AB * AB/BC = 1

For page 5 number 3

Tan28 = g/i

g/12.2 = tan28

cross multiplying to have

g = 12.2*tan28

g = 12.2 * 0.5317

g = 6.5

b) the angle I is given as 90-28 degrees

<I = 62 degrees

To find the side h we use the Pythagoras theorem

h² = (12.2)² + (6.5)²

h² = 148.84 +42.25

h²= 191.09

h=√191.09

h= 13.8

For page 6

1) Sin42 = x/18

x=18*sin42

x = 18*0.6691

x = 12.0

2) cos28 = 6/x

xcos28 = 6

x = 6/cos28

x [= 6/0.8829

x = 6.8

3)  Tan63 = x/34

x = 34*tan63

x= 34*1.9526

x = 66.4

4) Sin50 123/x

xsin50 = 123

x = 123/sin50

x = 123/0.7660

x =160.6

5)  Sin57 = P/8

Pole = 8sin57

the pole = 8*0.8387

The pole = 6.7

Answer: the price of one senior citizen ticket is $10, and the price of one student ticket is $5.

Step-by-step explanation:

Let's assume the price of one senior citizen ticket is 's' dollars and the price of one student ticket is 't' dollars.

According to the given information, on the first day, the school sold 7 senior citizen tickets and 11 student tickets, totaling $125. This can be expressed as the equation:

7s + 11t = 125 ---(1)

On the second day, the school sold 14 senior citizen tickets and 8 student tickets, totaling $180. This can be expressed as the equation:

14s + 8t = 180 ---(2)

We now have a system of two equations with two variables. We can solve this system to find the values of 's' and 't'.

Multiplying equation (1) by 8 and equation (2) by 11, we get:

56s + 88t = 1000 ---(3)

154s + 88t = 1980 ---(4)

Subtracting equation (3) from equation (4) eliminates 't':

(154s + 88t) - (56s + 88t) = 1980 - 1000

98s = 980

s = 980 / 98

s = 10

Substituting the value of 's' back into equation (1), we can solve for 't':

7s + 11t = 125

7(10) + 11t = 125

70 + 11t = 125

11t = 125 - 70

11t = 55

t = 55 / 11

t = 5

Therefore, the price of one senior citizen ticket is $10, and the price of one student ticket is $5.

To build a hydraulic model with WaterCAD for a water distribution system, key elements include network topology, pipe and node properties, while operations and consumption data are needed for model calibration and analysis.

To build a hydraulic model using WaterCAD for a water distribution system, the key elements and water supply information required are as follows:

The physical layout and configuration of the water distribution system, including pipes, valves, pumps, reservoirs, and other components.

Information about the pipes in the system, such as diameter, length, material, roughness, and elevation.

Details about the nodes or junctions in the network, including their elevations, demands, and storage capacities.

Specifications of pumps and valves, including their types, operating curves, and control settings.

Data related to reservoirs, such as their elevations, storage capacities, and inflow/outflow characteristics.

Input data for boundary conditions, such as fixed pressures or flow rates at specific points in the network.

To run and calibrate the hydraulic model, the following network, operations, and consumption data are needed:

Flow patterns, hydraulic demands, and operational scenarios that represent different usage conditions.

Information about pump schedules, valve settings, and control strategies employed in the system.

Water consumption patterns, including demands at different times of the day, week, or year, as well as any specific consumption profiles or patterns.

Data related to external influences on the system, such as upstream flows, pressures, or demands from neighboring networks.

By utilizing this comprehensive set of network, operations, and consumption data, WaterCAD can accurately simulate and analyze the hydraulic behavior of the water distribution system, allowing for efficient operation and calibration of the model.

To determine if the vector V3=(24, -1, 5, 0, 3) belongs to the span of vectors Vy and Vz, we need to check if V3 can be expressed as a linear combination of Vy and Vz. The answer is: False

Let's denote the vectors Vy and Vz as follows:
Vy = (R, V12, 0, 3) Vz = (V, 1, 3, 0)

To check if V3 belongs to the span of Vy and Vz, we need to see if there exist scalars a and b such that:
V3 = aVy + bVz

Now, let's try to solve for a and b by setting up the equations:
24 = aR + bV -1 = aV12 + b1 5 = a0 + b3 0 = a3 + b0 3 = a0 + b3

From the last equation, we can see that b = 1. However, if we substitute this value of b into the second equation, we get a contradiction:
-1 = aV12 + 1

Since there is no value of a that satisfies this equation, we can conclude that V3 does not belong to the span of Vy and Vz. Therefore, the answer is: False

Step-by-step explanation:

The solution to the equation 1/(x-1) = x² + 1 means the one x value that will make both sides equal. If we look at the table, notice how when x = 1.35, f(x) values are closest to each other for both equations, signifying that x = 1.35 is approximately the solution. Thus, Annalise is correct.
