Answer:

448

Step-by-step explanation:

This is  a proportion question. Keep the heights on one side of the proportion and the shadow length on the other.

height ratio  shadow ratio

40 cm / x = 25 / 280             Cross multiply

25x = 40 * 280                      Combine

25x = 11200                            Divide by 25

x = 11200/25

x = 448 cm

The height of the corn plant is 448 cm

A web store offers two versions of a popular song. The size of a standard version is 2.9 MB. The size of the high-quality versio
olasank [31]

Answer:

This problem is a great systems of equations problem--you have two different variables: song size and number of songs.

Let's call the number of standard version downloads (S) and the high quality downloads (H).

You can make two statements:

For number of songs downloaded: S + H = 910

For download size: 2.8(S) + 4.4(H) = 3044.

S will be the same number in both equations and H will be the same number in both equations, so to find S, we can rearrange the first statement to H = 910 - S, then substitute or plug in (910 - S) wherever you see an H in the second equation so that you have only S's in your equation. Should look like this:

2.8(S) + 4.4(910 - S) = 3044

2.8S + 4004 - 4.4S = 3044

-1.6S = -960

s = 600

Your question only asks for the standard version downloads, but to help you out in future Systems situations-

You can also solve for H once you have S by plugging it into either of your equations like this:

600 + H = 910

-600

H=310

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
