ANSWER

The explicit formula is :

a_n = 8+ 3(n - 1)

EXPLANATION

The given sequence is

8,11,14,17,20,23,26,...

The first term is

a_1=8

The common difference is

d=11-8

d=3

The explicit formula is given by:

a_n = a_1 + d(n - 1)

We substitute the values to get,

a_n = 8+ 3(n - 1)

Seventh graders collected some gold sand on a class field trip.
satela [25.4K]

Answer:

Class 7A collected 4.8 ounces of pure gold.

Step-by-step explanation:

<u>Key skills required are: Percentages, Multiplication</u>

<u />

  1. We only need the information about Class 7A. They collected 40 oz that contains 12% gold.
  2. In other words, this means that 12% of that 40 oz gold sand is pure gold.

Here we have to do 12% x 40 to find the number of oz of pure gold. We first have to convert 12% into a decimal. Divide it by a 100 (or move the decimal point 2 places to the left) and you will get 0.12.

<em>Do 0.12 x 40 and you will get 4.8</em>

Therefore, there are 4.8 oz of pure gold in Class 7A's gold sand
