Step-by-step explanation:
1. P(pen then pencil) = 15/25 × 10/25 = 3/5 × 2/5 = 6/25
2. P(pen then pencil) + P(pencil then pen) = 6/25 + 6/25 = 12/25
3. P(pencil then pencil) = 10/25 × 10/25 = 2/5 × 2/5 = 4/25
4. P(at least 1 pen) = 1 − P(no pen) = 1 − 4/25 = 21/25
Answer:
45 3/10 mph
Step-by-step explanation:
30 1/5 /2 = 15 1/10
15 1/10 x 3 = 45 3/10 mph
Answer:
Set the two equations equal to each other if you want me to solve tell me.
So.... 15x+10=16x+3
-15 -15
10=1x+3
-3
7=x
Answer:
7 hours=455 miles 6 hours=3
Step-by-step explanation:
FIrst, lets find how many mph he is at. 845/13= 65mph
So, if he goes for 7 hours, he would do 7*65, which is 455 miles
Then we can do 6*65 which is 390
Right, Isosceles.
Right angle means it it a Right Angeled Triangle (square in bottom left.)
Isosceles because it has two sides the same length, not matching the third.
