Answer:
If Zahara finishes a level in 201 seconds, she earns:
Step-by-step explanation:
To identify the number of points that Zahara obtained when she finished a level in 201 seconds, you must use the given expression:
- -5.5 + 500+ 0.9t + (1 - 1.9t)
Where:
As Zahara took 201 seconds to finish a level, we're gonna replace this value in the equation:
- -5.5 + 500+ 0.9t + (1 - 1.9t)
- -5.5 + 500+ 0.9(<u>201</u>) + (1 - 1.9[<u>201</u>]) (we're not use the unit "seconds", because we don't need it in this calculation)
- -5.5 + 500+ 180.9 + (1 - 381.9)
- -5.5 + 500+ 180.9 - 380.9 (You can organize the numbers is you want)
- 500 + 180.9 - 380.9 - 5.5
- <u>294.5 points</u>
As you can see, <u>Zahara obtains 294.5 points if she finishes the level in 201 seconds</u>.
Lets say she cuts squares of x by x in length.
Area of bottom will be (20 - 2x)(11 - 2x) = 80 inches squared
220 - 40x - 22x + 4x^2 = 80
4x^2 - 62x + 140 = 0
x^2 - 15.5x + 35 = 0
Using quadratic equation;
you get x = 2.743753901 0r 12.7562461 inches
The length of the square cannot be more than 11 inches
So the only squares you can cut are:
2.743753901 inches by 2.743753901 inches squares.
24 3/4 divided by 1 3/8 equals 18
The answer is 3
This is because to find the volume of X, you just do the side length of X^3, and to find the volume of Y, you do Y^3.
Since both of these values are to the power 3 (X^3 and Y^3), you need to undo it to find the side length of X divided by the side length of Y, and to undo this you need to do something called cube rooting
And the cuberoot of 27=3
