Answer:

Natalie's total spread = 18

Step-by-step explanation:

The 'spread' of a crossword puzzle tournament player is computed as his/her total score minus the opponent's total score.

Natalie's scores are:

N=410+380+395+370+320+360=2,235

Opponent's scores are:

O=395+360+412+355+340+355=2,217

Natalie's total spread = 2,235 - 2,217 = +18

Natalie's total spread = 18

Answer: yessssiir

Step-by-step explanation:

Answer:

1) 3+4.50x = total cost

2) continuous, because x will be the continuous change depending on the pounds

Step-by-step explanation:

The equation to model the situation is C(w) = 3 + 4.50w, and the domain is continuous because weight (w) can take any real number value for the package.

1. The equation to model this situation can be written as follows:

Total Cost (C) = $3 (Cost of the box) + $4.50 per pound (Weight of the package in pounds)

Let's denote the weight of the package in pounds as "w." The equation is:

C(w) = 3 + 4.50w

2. The domain in this situation is continuous. The weight of the package (w) can take any real number value, and the cost function C(w) is valid for all real values of weight. There are no restrictions or gaps in the possible values of weight, meaning it is continuous.

In summary, the equation to model the situation is C(w) = 3 + 4.50w, and the domain is continuous because weight (w) can take any real number value for the package.

Answer:

Light is about 299,999,700 mps (meters per second) faster than sound in dry air.

Step-by-step explanation:

We know that the speed of light is about 3 × 10 ^ 8 meters per second and that the speed of sound in dry air is about 3 × 10 ^ 2 meters per second. We need to solve 3 × 10 ^ 8 minus 3 × 10 ^ 2.

3 × 10 ^ 8 - 3 × 10 ^ 2 =

300,000,000 - 300 = 299,999,700

Light is about 299,999,700 mps (meters per second) faster than sound in dry air.

Step-by-step explanation:

Answer: A. 300 - 70h = 30

Step-by-step explanation:

Rest of the question is:

Which of these following equations represents the hours, h, the bus has travelled.

The driver is going at 70 kilometers per hour meaning that for every hour that passes, 70km has been traveled. Expression to find the distance travelled given hours is:

= 70h

There are 300km between the two cities and 30km are left in the journey. Expression is therefore:

300 - 70h = 30

This shows that when you find the distance travelled so far and deduct it from 300, you will get 30km.

The equation that can represent the distance for which the bus has travelled is 300-70h=30.

The speed can be defined as the rate of change of position of an object with respect to time. It is given by the formula,

[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]

The distance travelled by bus is 270 kilometers (300-30), because the distance left between the bus and Orlando is 30 kilometers. while the speed of the bus is 70 kmph.

Let the time for which the bus travelled be h, therefore, the equation that can represent the hours for which the bus has travelled is,

Total distance - distance covered in h hours = distance left between bus and Orlando

[tex]300-70h=30[/tex]

Thus, the equation that can represent the distance for which the bus has travelled is 300-70h=30.

Answer:

85 degrees

Step-by-step explanation:

If you find the missing angle for the triangle it would be 95 because 60+25 is 85 then 180-85 is 85. For a straight line you have to have 180 degrees, so you know the first angle is 95 degrees so the second one would have to be 85 degrees :)
