I don't see a diagram, but if the portion of the tennis region you are asked to analyze doesn't intersect anywhere else/any other regions pertaining to other sports, wouldn't the sport chosen by these students be solely tennis?
Answer:
Step-by-step explanation:
Answer:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
Answer:
The 36 guests will be needing 15 liters of soda
Step-by-step explanation:
In this question, we are told we need 5 liters of soda for every 12 guests that are at a party. Now, we have 36 guests attending the party and we need to calculate the amount of soda in liters that we will be needing.
From the first statement, we need 5 liters for 12 guests, this means each of the guest would need 5/12 liters or let’s just say 5/12 liters/guest
Now, we have 36 guests, the amount in liters needed will be 5/12 * 36 = 15 liters
