Answer:
j. Pam, Tia, Veronica, Lily (if it's youngest to oldest)
Step-by-step explanation:
If Tia is 8 yrs old and she's 2 yrs older than Pam, then Pam must be 6 yrs old. Pam si 5 yrs younger than Veronica who must be 11 + 4 = 15.
Tia: 8 yrs.
Veronica: 11 yrs
Pam: 6 yrs.
Lily: 15
To find the cross product, you can set this up as a proportion. Please see the attached paper for one of the proportions you could use.
You would then multiply the numbers that are diagonal from each other.
You would have 21(8) = 12x or
168=12x.
A. 9
B. 24
C. 6
D. 16
Step-by-step explanation:
Given ratios are;
A. 2 : 3 = 6 : x
Product of mean = Product of extreme

Dividing both sides by 2

B. 4 : 7 = x : 42
Product of mean = Product of extreme

Dividing both sides by 7

C. 2x : 48 = 3 : 12
Product of extreme = Product of mean

Dividing both sides by 24

D. 12 : 15 = x : 20
Product of mean = Product of extreme

Dividing both sides by 15

So since its a right triangle, we can use the pythagorean theorem, which is
. Since we know that 2 and 3 are our legs and x is our hypotenuse, we can solve the equation as such:

Since √13 can't be further simplified, that is your final answer.
