2). 1/4
3). 1. 117° 2. 63°
4). There are 42 students in the yearbook club and 61 in the drama club
5). 1). both are 45 ° 2). both are 3 units

The Answer is that the present value of $100 is $100. Because this $100 dollar is deposited today so the time is equal to zero and when time is zero the value of amount is the value of amount itself.
Answer: -9/5
Step-by-step explanation: To find the slope, we must understand that the slope of a line is defined as the ratio rise/run.
The rise is the vertical direction of the line and the
run is the horizontal direction of the line.
So to start, I am going to pick 2 points on this line.
<em>You want to find points where the line crosses the four corners.</em>
In the diagram, those would be the points (-4, 5) and (1, -4).
Now, we can use slope formula.
Slope = y₂ - y₁ / x₂ - x₁
So we have -4 - 5/1 - -4 which simplifies to -9/5.
So the slope is -9/5.
For the first question, all you need to know is that the (amount you want) divided by (the amount of cards total) is the probability of getting the amount you want at random. for example, if there are 3 red marbles in a bag of ten marbles, you divide 3 by 10 (0.30) the probability of picking up a red marble is 30%. try adding up how many cards you want to pick up by the number of cards total.
Answer:
15
Step-by-step explanation:
we know that the boys in total cost 75 dollars and the girls cost 90.
75 and 90 share but one common factor and that is 15.
Therefore, we can conclude that the tickets cost $15.
