Answer:

1.9 kg

Step-by-step explanation:

Empty container: 3/10 kg = 0.3 kg

Container half filled: 1 1/10 kg = 1.1 kg

Mass of water that fills it halfway: 1.1 kg - 0.3 kg = 0.8 kg

Mass of water that fills it completely: 2 * 0.8 kg = 1.6 kg

Mass of container completely filled with water: 0.3 kg + 1.6 kg = 1.9 kg

The revenue from selling x shirts is r(x) = 11x. The cost of buying x shirts is c(x) = 6x + 20. The profit from selling x shirts
oee [108]

Answer: option A is the correct answer.

Step-by-step explanation:

The expression that relates revenue, profit and cost is

Profit = Revenue - Cost

The revenue from selling x shirts is r(x) = 11x. The cost of buying x shirts is c(x) = 6x + 20. Therefore,

p(x) = r(x) - c(x)

p(x) = 11x - (6x + 20)

By expanding the bracket, the minus sign will alter each term in the bracket. Therefore,

p(x) = 11x - 6x - 20

p(x) = 5x - 20

Is the sequence 2, 1, 1/2, 1/4,.. A)arithmetic B) geometric C) both D)neither
Sonbull [250]
The given sequence is a geometric sequence. The property of geometric sequence is that each term is multiplied by a specific number known as "common ratio" to get the next term. In this case the common ratio is 1/2.
2 x 1/2 = 1
1 x 1/2 = 1/2
1/2 x 1/2 = 1/4 
and so on..

compare and contrast the difference between simplify a fraction and simplify a radical. What is the ultimate goal for each?
yanalaym [24]
<u>Compare:</u><u>
</u>
- The goal of reducing a radical and a fraction is to literally simplify the numbers to make them easier to work with
<u>
Contrast:
</u>- The action of simplifying fractions<u /> is dividing the numerator and denominator by a common factor. 
- The action of simplifying radicals is making sure the radicand has no square factors. You separate the radicand into two parts, one of which can be square rooted into a whole number.
<em>Example:</em>
\sqrt{18} = \sqrt{9} * \sqrt{2} = 3 \sqrt{2}
