How many times as great is the diameter of a pinhead as the diameter of a cloud-water droplet

Mathematics
1 answer:
Ulleksa [173]1 year ago
5 0

Given:

The diameter of cloud-water droplet is

10^{-5}

The diameter of pinhead is 0.001.

Explanation:

Divide the dimater of cloud-water droplet by dimater of pinhead to determine the times as great is the diameter of a pinhead as the diameter of a cloud-water droplet .

\begin{gathered} a=\frac{0.001}{10^{-5}} \\ =0.001\cdot10^5 \\ =100 \end{gathered}

So diameter of a pin-head is 100 times the diameter of water-droplet.

Answer:

Surface area is 66 units.

Step-by-step explanation:

I calculated the area of each rectangle in the net.

3 x 7= 21

3 x 7= 21

2 x 3= 6

2 x 3= 6

2 x 7= 14

21 + 21 + 6 + 6 + 14 = 66

Use the elimination method to solve the system of equations.<br><br>3x-5y= -16<br><br>2x+5y=31
Sholpan [36]
5x = 15
x = 3

3(3) - 5y = -16
9 - 5y = -16
5y = -16 - 9
5y = - 25
y = - 5

A 12 ounce can of store brand tomato paste costs $1.46 at a supermarket. The unit price of the sauce is listed on the shelf belo
kykrilka [37]
You can calculate it by divided but most of the people get confused about is it gonna be 12/1.46 or 1.46/12. The correct is 1.46/12 because take the money divided all 12 to get a unit price if you take 12/1.46 which mean divided all ounce can to money and that makes nonsense.


So 1.46/12 = $0.12 for each ounce can

Two similar triangles have corresponding sides measuring 3 cm and 7 cm determine the ratio of their respective areas
Scrat [10]
If two similar triangles have side lengths 3cm and 7cm then we can determine that the scale factor for the lengths is: 7/3

Now, we have to work out the area scale factor !

This is simple, since area is given in cm² then all we have to do is square our original scale factor!

So,

7/3² = 49/9

So, we can say that the ratio of the area would be:

x : 49/9x

Hope this helps! <3
