Answer:
x^2/25-y^/16=1 or y^2/16-x^2/25=1
2 hr 15 min = 2

hours = 2.25 hours
"how far" means distance ... so distance = rate x time
distance = 56 x 2.25 =
126 miles
"how long" means time ... so using the same formula
168 = 56 x time
divide both sides of the equation by 56 to solve
3 hours = time
Answer:
Width = 16.875 inches
Step-by-step explanation:
We given that the ratio of the Length/Width = 8/3, and that the length is 45 inches long, so 45/Width = 8/3. Therefore solving for the Width by cross multiplying gives: Width = 3L/8 = 3*45/8 = 16.875
Answer:
In this subtraction, PR5T and 47Y6 represent 4-digit numbers. What number does PR5T represent?
PR5T - 47Y6 = 1998
Step-by-step explanation:
Probability of an event is the measure of its chance of occurrence. The value of the probability P(cream and sugar) is given by: Option A: 0.4
<h3>What is the addition rule of probability for two events?</h3>
For two events A and B, we have:
Probability that event A or B occurs = Probability that event A occurs + Probability that event B occurs - Probability that both the event A and B occur simultaneously.
This can be written symbolically as:

For the considered case, the probabilities are:
- P(cream) = 0. 5
- P(sugar) = 0. 6
- P(cream or sugar) = 0. 7
Thus, we get;
P(cream or sugar) = P(cream) + P(sugar) - P(cream and sugar)
0.7 = 0.5 + 0.6 - P(cream and sugar)
P(cream and sugar) = 1.1 -0.7 = 0.4
Thus, the value of the probability P(cream and sugar) is given by: Option A: 0.4
