Answer:
125 mph
Step-by-step explanation:
This can be calculated as a simple rule of 3.
In rule of 3 problems, you need to first identify the measures and whether they are direct or inverse to each other.
If they are direct to each other, if one value increases the other will increase too. For example, lets suppose that the Buffalo Bills have won 3 of 4 games. When there are 8 games, then will have won 6, keeping this proportion. Here, the measures are the number of games and the number of Buffalo Bills wins.
Now if they are inverse to each other, if one value increases the other will decrease. For example, if you travel at 60 mph, you will need 6 hours to arrive at your destination. At 80 mph, you will need less time. So, a the average speed increases, the time you need will decrease.
In this case the speeds is proportional to the time. So, if the time increases, the speed will increase too. It can be calculated by the following rule of 3.
Speed Time
100 mph - 0.8 seconds
x mph - 1 second
x = 100/0.8 = 125 mph.
Answer:
Similar - Top center, bottom left
Not similar, different shape - Top left, bottom right
Not similar, different ratio of side lengths - Top right, bottom center
Step-by-step explanation:
We can see automatically that the top left and bottom right are not similar because they are a triangle and a trapezoid, not a rectangle.
Top right is not similar because of its different ratio of sides. The ratio for the sides of the original rectangle is 3:7, while the ratio of the top right is 2:3.5 .
Bottom center is not similar because of its different ratio of sides as well, as its ratio is 6:12

3*sqrt(7)
3 times the square root of 7
====================================================
Explanation:
I'm assuming the V stands for square root. You can write sqrt(63).
The idea is to factor 63 in such a way that one factor is the largest perfect square possible, that way we can pull the root apart to simplify as shown above. The rule I used for the second step is 
Every number has three cube roots.
The only real cube root of -64 is <em>-4</em> .
The other two cube roots of -64 are a pair of complex conjugates.
I'm too lazy to calculate them right now, and you didn't ask for them
anyway.
The function that represents the Scooter Company's total profit is given by:
P(x) = -2x² + 250x - 2,000.
<h3>How to calculate the profit function?</h3>
The profit function is calculated by the <u>revenue function subtracted by the cost function</u>, hence:
P(x) = R(x) - C(x).
In this problem, we have that:
- The revenue function is: R(x) = 400x - 2x².
- The cost function is: X(x) = 150x + 2000.
Hence the profit function is:
P(x) = R(x) - C(x).
P(x) = 400x - 2x² - (150x + 2000).
P(x) = -2x² + 250x - 2,000.
