The sum of ages Afful and Naomi is 34. In 5 years time , Afful will be 2 times the age on Naomi now. How old are they now.
GenaCL600 [577]

Answer:

Afful is 21 and Naomi is 13.

Step-by-step explanation:

Let A represent the age of Afful and N represent the age of Naomi.

The sum of their ages is 34. In other words:

A+N=34

In 5 years time, Afful will be two times the age of Naomi <em>now</em>. In other words:

A+5=2N

Solve for the system. Substitute.

A+N=34\\A=34-N\\34-N+5=2N\\39=3N\\N=13\\\\A=34-N\\A=34-(13)\\A=21

Afful is currently 21 and Noami is currently 13.

nalin [4]

Answer:

Zamzam could make $400 per day.

Step-by-step explanation:

Given:

Zamzam can sell 1 liter of camel milk for $1.

Jasmin herd produces 400 liters per day.

Now, to find the money Zamzam could make per day.

By multiplying we get the money zamzam could make:

<em>If cost of 1 liter milk = $1.</em>

<em>Then cost of 400 liters milk = $1 × 400.</em>

                                              =  $400.

Therefore, zamzam could make $400 per day.

What is the nth term of a geometric sequence that has a common ratio of 6 and 24 as the third term
Ivanshal [37]
The common ratio r is 6, while the third term (ar²) is 24.
Nth  term in a GP is given by the formula ar^n-1, thus the third term is ar²
ar²= 24
thus, a × 36 = 24
         a =24/36
The ninth term is given by ar^8
= (24/36)× 6^8
= 1119744.
