Answer:

1:2

Step-by-step explanation:

If 6 have never flown, then out of 18, only 18-6=12 have flown

Expressed as 6:12

Simply the above by dividing both sides by 6

The new ratio is 1:2

<h3>What is a system of linear equations?</h3>

A system of linear equations can be defined as an algebraic equation of the first order that has two (2) variables with each of its term having an exponent of one (1).

In this exercise, you're required to match the systems of linear equations with their respective solutions as shown in the image attached below.

Can anyone explain to me how to do this question ? ty !!

julia-pushkina [17]

Step-by-step explanation:

use a little imagination.

the whole thing is a combination of churches and half- circles.

and you know the formula for the area of a circle ?

A = pi×r²

so, the only difficulty is to find the circles and then the radius of each involved circle.

when you look at the picture, the shaded area is almost identical to the lower half of the main circle.

2 bumps "look" over into the other side, but one equally sized bump is removed from this lower half.

so, as a first step we will calculate the area of the lower half of the main circle.

the diameter is 24 m, so the radius is half of that : 12m

the area of the large circle is therefore

pi×12² = 144×pi m²

since we only need the (lower) half, we divide this by 2 :

144×pi / 2 = 72×pi m²

the bumps up and down are actually half-circles too. just of smaller circles.

since AB = BC = CD, we know each of these lines are 1/3 of the main diameter AD.

so, the diameter of the smaller circles is 24/3 = 8 m

and their radius is half of that = 8/2 = 4m

the area of such a small circle is therefore

As = pi×4² = 16×pi m²

and a small half-circle area is then

16×pi / 2 = 8×pi m²

so, for the full shaded area I need to take the large half-circle and add 2 small half-circles, and then subtract 1 small half-circle.

so, in total I only need to add 1 small half-circle.

Ashaded = 72×pi + 8×pi = 80×pi m²

QveST [7]

Answer: 9 L

Step-by-step explanation:

Given

The dimension of the rectangular container is $40\times 30\times 25\ cm^3$

It is filled with $\frac{3}{5}$ of the height

Water present in the container

$\Rightarrow 40\times 30\times 25\times \dfrac{3}{5}\\\\\Rightarrow 18000\ cm^3$

Also, $1\ L=1000\ cm^3$

$\therefore 18,000\ cm^3=18\ L$

Now, half of the water is poured out

So, half is left

$\Rightarrow \dfrac{18}{2}=9\ L$

Thus, 9 L of water is left in the container
