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

A.35
B. 60
C. 85
D. 95
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 :)

What is the value of x?
3 (-1 - 8x) = -3
Answer:
x = 0
Step-by-step explanation:
3 x -1 = -3 and 3 x -8x = -24x
-3 + 3( the opposite of the -3 given in the parentheses) = 0
-24x = 0
0/-24 (from -24x)= 0
x = 0

The speed of light is about 300,000,000 meters per second. That's
about 3 * 10^8 meters per second. The speed of sound in dry air is
about 3 * 10^2 meters per second.
About how many times faster does light travel than sound in dry air?
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.

I sold something on ebay and I go to the UPS store to
ship the package. The cost for the box is $3, and it cost
$4.50 per pound to ship.
1) Write an equation to model this situation.
2) Is the domain discrete or continuous? Explain
First you will input the equation, then submit it, then you
will be asked to explain.
imple
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.
