A sports drink bottle contains 16.9 fluid Ounces. Andre drank 80% of the
bottle. How many fluid Ounces did Andre drink?

Answers

Answer:

13.52 fluid ounces should be the right answer! :)

Step-by-step explanation:

Andre drank from the bottle 13.52 fluid ounces if he drank 80% of bottle.

What is Percentage?

Percentage is defined as the parts of a number in a whole of 100. This is denoted by the symbol '%'.

In other words, percentage can be defined as the ratio expressed as a fraction of 100.

Any number can be expressed as a percentage of another number by dividing the number with the whole of other number and then multiplying with 100.

Given that, fluid contained in a sports bottle = 16.9 fluid ounces.

Andre drank 80% of the fluid contained in the bottle.

80% of the bottle = 80% × 16.9

= (80 / 100) × 16.9

= 0.8 × 16.9

= 13.52

So this is the total fluid ounces Andre drink.

Hence Andre drank 13.52 fluid ounces from the bottle.

Calculate the area of the parallelogram, giving your answer correct to 3 significant figures.

Answers

Answer:

114 units²

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, so

AB = CD , that is

13x - 7 = 5x + 9 ( subtract 5x from both sides )

8x - 7 = 9 ( add 7 to both sides )

8x = 16 ( divide both sides by 8 )

x = 2

Then

5x + 9 = 5(2) + 9 = 10 + 9 = 19

3x = 3(2) = 6

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height ), thus

A = 19 × 6 = 114 units²
