Answer:
The number of A's Dina got = 5/11 × 77 = 385
/11 = 35
Step-by-step explanation:
The number of A's Pete , Chris and Dina received are in the ratio of 4:2:5.
Let the total number of A's = y
Total from ratio = 4 + 2 + 5 = 11
chris A's = 2/11 × y
pete's A's = 2/11 × y + 14 = 4/11 × y
pete's A's
2/11 y + 14 = 4/11 y
14 = 4/11 (y) - 2/11 (y)
14 = 2/11 (y)
cross multiply
2y = 14 × 11
divide both sides by 2
y = 154/2
y = 77
Total number of A's = 77
The number of A's Dina got = 5/11 × 77 = 385
/11 = 35

Step-by-step explanation:
science(density and buoyancy)
I have answered this question before.
Given:
Bob has three kids whose ages has the product of 72. I will only be able to give you a set of 3 numbers to represent the ages. Had the sum of the ages been given, the specific ages would be provided.
I just did a prime factorization of 72.
72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1
1 x 2 x 2 x 2 x 3 x 3 = 72 ⇒ 2³ x 3²
There are a lot of possible combinations, here are a few.
1 x 8 x 9 = 72 ⇒ 1 + 8 + 9 = 18
1 x 4 x 18 = 72 ⇒ 1 + 4 + 18 = 23
<span>2 x 4 x 9 = 72 ⇒ 2 + 4 + 9 = 15</span>
