Answer:
21 vowels.....15 consonants.......added = 36 tiles
probability of first picking a consonant : 15/36 reduces to 5/12
replacing it...
probability that second pick is a vowel : 21/36
probability of both : 5/12 * 21/36 = 105 / 432 reduces to 35/144 <===
Step-by-step explanation:
Answer:
The answer is B
Step-by-step explanation:
Convert 2/5 to a decimal and you get .4, or 40%. 40% of the band members also sing, so yes, the band has the same number of string instrument players and singers.
Let’s call the speed of the slower car S, then the speed of the other is S+10mph.
At 5pm they have been travelling for 3 hours. The slower car travels a distance 3S and the faster one 3(S+10).
But the two distances must add up to 240 miles so 3S+3(S+10)=240, 3S+3S+30=240, 6S=210, S=35 mph. The faster car’s speed is 45mph. We can see that 3S is the same distance as 3x, so x=S=35 mph, and the distance the faster car travels is 3×45=135 miles.
