Answer: 7

Step-by-step explanation:

Rule of 3. Let's put the ounces on the left side and the price on the right side.

$\frac{12}{x}=\frac{0.84}{0.49}\\$

$x=\frac{(12)(0.49)}{0.84} \\x=7 ounces$

Sandra is a real estate agent and rams 5000 commission on the selling of a 62,000 house. what is the percent of commission she r

sveta [45]

To find a percent, you use this simple formula:
5000/62000 = x/100

In this case, x is going to be your percent of commission.

So, to find this, you first divide 5000 by 62000, which is about equal to 0.08.

Now your equation looks like this:
0.08 = x/100

Next, you multiply both sides by 100 to reverse the operation. Now, your equation will look like this:

8 = x

So, the answer is 8%.

give an example of a convergent infinite series whose sum equal 3/5. explain how you know your series converges and write out wo

krek1111 [17]

Answer:

The series 1/5, 2/15, 4/45, 8/135... converges and sums up to 3/5

Step-by-step explanation:

Consider the infinite geometric series

1/5, 2/15, 4/45, 8/135...

With first term, a=1/5

common ratio, r = ⅔

The series converge because the common ratio, |r|<1.

The sum to infinity of a geometric series, S= a/(1-r)

S= 1/5 ÷ (1-⅔) = 1/5 ÷ 1/3 = 3/5

Therefore, the geometric series 1/5, 2/15, 4/45, 8/135... sums up to 3/5.

X +30=2X-4 solve x . .

MArishka [77]

Answer: X = 34

Step-by-step explanation:

Let's solve your equation step-by-step.

x+30=2x−4

Step 1: Subtract 2x from both sides.

x+30−2x=2x−4−2x

−x+30=−4

Step 2: Subtract 30 from both sides.

−x+30−30=−4−30

−x=−34

Step 3: Divide both sides by -1.

−x

−1

−34
