Let the total number of cans be x and the total number of tennis balls be y,
Since increasing the total number of cans causes the total number of tennis balls to increase too, x and y is direct in proportion.
Let the constant be k,
y = kx
45 = k9
k = 45/9
= 5
The constant of the proportionality for this situation is 5.
Answer:
200 ft²
Step-by-step explanation:
Each face is an isosceles right triangle with a hypotenuse of length 10 ft. The area of each of those triangles is
A = 1/4·h² . . . . where the h in this formula is the hypotenuse length
So, the area of the four faces (the lateral area of the pyramid is 4 times this, or ...
A = 4·1/4·(10 ft)² = 100 ft²
Of course, the base area is simply the area of the square base, the square of its side length:
A = (10 ft)² = 100 ft²
So, the total area is the sum of the lateral area and the base area:
total area = 100 ft² +100 ft² = 200 ft²
_____
If you think about this for a little bit, you will realize the pyramid must have zero height. That is, the slant height of a face is exactly the same as the distance from the center of an edge to the center of the base. "Not drawn to scale" is a good description.
Answer:
<h2>A.</h2>
Step-by-step explanation:
The given expression is
Where the constant term is .
A constant term refers to an initial condition of the problem. In this case, we are talking about time related to money earned in dollars. So, in this case, 85 refers to total money earned in 2008, because that's the initial year of the period.
So, basically, the constant term refers that the company earned 85 billion dollars in 2008, which is the meaning of the initial condition of this problem.
Therefore, the right answer is A.
Answer:
4,810
Step-by-step explanation:
$10 per ticket times 741 people (10 * 741) is 7,410, then subtract the cost to produce the play, 7,410 - 2600 = 4,810.
