<span>Provided that no one can receive more than one prize, there are 50*49*48= 117600 ways to distribute the prizes. The first prize can be given to any of the 50 people, the second to any of the remaining 49, and the third to the remaining of the 48, multiplying these possibilities together leads to the answer.</span>
Answer:
correct you got the answer
Step-by-step explanation:
Hey there!
This situation can be represented by the following equation:
y = 20 + 20x
This is because she starts without any time passing with 20 pounds of cans and collects 20 more pounds every week.
So when x = 0, y = 20.
The variable y is the number of pounds of cans collected, while x is the number of weeks passed.
If we want to find the number of pounds of cans she has after 10 weeks, we have to substitute x = 10 like this:
y = 20 + 20(10)
Multiply 20 x 10.
y = 20 + 200
Add 20 + 200.
y = 220
Your answer is 220 pounds, the second option shown!
Hope this helps!
Answer:
C. (y + 3)²/64 - (x + 1)²/36 = 1
Step-by-step explanation:
This is a hyperbola with a vertically tranversed axis, so the general equation for it is:
where h and k are the coordinate for the center (h, k)
we're given center is (−1, −3), so
h = -1
k = -3
The information about "<em>One focus of a hyperbola is located at (−1, 7). One vertex of the hyperbola is located at (−1, 5)</em>" are irrelevant because the a and b values are the same for all the answers. So we literally only needed the center of the hyperbola to find our answer.
The only answer with (y+3) and (x+1) is C.
7:2
Step-by-step explanation:
Step one is to think about how often tacos are made. Tacos are made often. Now think about how often Wraps are made, not very often. After some research, the ratio is 7 burritos to 2 wraps. This would make the answer 7:2. Unfortunately tacos are more loved than Wraps.
