CF = CD + DF (since D is simply a point on the line, and C to that point added onto F to that point is CF), so 4y-9+2y-7=14. Adding it up, we get 6y-16=14 and adding by 16 we get 30=6y. Dividing both sides by 6, we get y=5. Plugging that into DF, we get 10-7=DF=3
Assuming that you're talking about a standard deck of 52 cards, there are 4 tens and 4 aces.
So, at the beginning, you have probability 4/52=1/13 to draw a ten.
You replace, and you have an identical probability to draw an ace (you still have 4 favourable cases over 52 total cases).
Multiply the two probabilities to find the answer:
Answer:
B, A, D, C
Step-by-step explanation:
Covert all units into grams.
540 g = 540 g
180,000 mg = 180g
0.8 tonnes = 800000 g
2.3 kg = 2300 g
Arrange in ascending order.
180,000 mg, 540 g, 2.3 kg, 0.8 tonnes
320 divided by 10 is equal to 32. So, the bakers can make 32 bagels per hour. Then, you do 32 times 18 which is equal to 576 bagels in 18 hours.
