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

What is the sum of this infinite geometric series
nordsb [41]

You probably know that for |r|, we have

\displaystyle\sum_{i=0}^\infty ar^i=\dfrac a{1-r}

Your sum starts at i=1, so it's equivalent to

\displaystyle\sum_{i=1}^\infty 12\left(\dfrac12\right)^i=\sum_{i=0}^\infty 12\left(\dfrac12\right)^i-12\left(\dfrac12\right)^0=\dfrac{12}{1-\frac12}-12=12

so the answer is A.

How do you simplify (-1 - 3 √(3) × (-1 - 3 √(3)
harina [27]

Answer:

4 + 6√(3)

Step-by-step explanation:

Two right parentheses seem to be missing here.  I think you meant:

(-1 - 3 √(3) ) × (-1 - 3 √(3) )

and this is the square of a binomial.  The resulting square is:

1 + 6√3 + 3, or 4 + 6√(3)
