Answer:

<h2>2.4 Litres of water</h2>

Step-by-step explanation:

80% of (3 litres)

You can take 3 litres to be 3000 ml which is how I solved it.

<h2>OPTION 1</h2><h2>_________</h2>

80/100 x 3000

=2400 or 2.4 litres

The same can go with not taking ml which you can just use litres

<h2>OPTION 2</h2><h2>_________</h2>

80/100 x 3

=2.4 litres

I used the ml since I do not need the calculator for that one and it is faster to calculate.

Part 10, What is the area of this figure? NO LINKS!!!

Tamiku [17]

Answer:

shaded area = 601 mm²

Step-by-step explanation:

Area of rectangle = Length * Breadth

Area of first section = 12 * 16 = 192 mm²

Area of 2nd middle section = 8 * ( 16 - 10 ) = 48 mm²

Area of the bottom section = 19 * 19 = 361 mm²

Area of total therefore = 192 mm² + 48 mm² + 361 mm²

= 601 mm²

Select the polynomial that is a perfect square trinomial.

Alina [70]

Answer:

16x^2 -8x +1

Step-by-step explanation:

The square of a binomial expands as ...

(a +b)^2 = a^2 +2ab +b^2

So, you need to look for a trinomial with first and last terms that are perfect squares and a middle term that is double the product of the roots of those terms.

This pattern matches ...

16x^2 -8x +1 = (4x -1)^2
