Henry has a bag containing 39 letter tiles, some consonants, and some vowels. He selects a tile without looking and then replace
adoni [48]

Answer:

21 consonant tiles

Step-by-step explanation:

Henry has a bag containing 39 letter tiles, some consonants, and some vowels.

He selects a tile without looking and then replaces it. If he pulls 7 consonant tiles and 6 vowel tiles, which is the most likely number of consonant tiles in Henry's bag?

Step 1

We add up the number of tiles that he pulls out of the bag

= 7 consonant tiles + 6 vowel tiles

= 13 tiles

Step 2

We divide the total number of tiles in the bag by the total number of tiles that was pulled out of the bag

= 39 tiles ÷ 13 tiles

= 3

Step 3

The most likely number of consonant tiles in Henry's bag is calculated as:

3 × The number of consonant tiles that was pulled out of the bag.

Hence:

3 × 7 consonant tiles

= 21 consonant tiles.

Therefore, the most likely number of consonant tiles in Henry's bag is 21 consonant tiles.

In a class there are 30 boys and 10 girls. what percent are girls?​
musickatia [10]

Answer:

I believe the answer would be 10%

Step-by-step explanation:

If you take 10% of 40 you get 4% however 40 is your total (100%) so therefore you would take the 4% multiply it by 2 and then you end up with 8% then you take 4% and divide it by 2 then add it on to your 8% then you end up with 10%

Hope this helps!

b = 12

Step-by-step explanation:

Complementary angles add to 90 degrees

a+b = 90
