This is a great method
I call it dot traveling
if you have 3.025 and 100 has 2 zeros you move your dot by 2 spaces so 302.5
next
if you have 10^5 you will need to look only at the five (note: this is ONLY on the number 10)
so we are going to move 3.025 by 5 spaces
notice how it doesnt have enough space? Add zeros!
So here 3.025 * 10^5 = 302500!
Hope I helped

You have two 30-60-90 triangles, ADC and BDC.

The ratio of the lengths of the sides of a 30-60-90 triangle is

short leg : long leg : hypotenuse
     1        :  sqrt(3)  :        2

Using triangle ADC, we can find length AC.
Using triangle BDC, we can find length BC.
Then AB = AC - BC

First, we find length AC.
Look at triangle ACD.
DC is the short leg opposite the 30-deg angle.
DC = 10sqrt(3)
AC = sqrt(3) * 10sqrt(3) = 3 * 10 = 30

Now, we find length BC.
Look at triangle BCD.
For triangle BCD, the long leg is DC and the short leg is BC.
BC = 10sqrt(3)/sqrt(3) = 10

AB = AC - BC = 30 - 10 = 20

In the figure below, k || o. Find the values of y and z.
jarptica [38.1K]

Answer:

y = 112

z = 27

Step-by-step explanation:

Alright,

So we know that a straight line adds up to 180. And looking at the figure, it looks like 68 + y = 180 if you do some visualization.

So, we can already calculate y.

y = 180 - 68

y = 112

Now we find z. z here is represented in an expression. We can see that y and the expression z is in are congruent to each other which means they will equal each other. And since we know that y = 112, we know that the expression z is in is also equal to 112.

So we set up an equation like so:

112 = 3z + 31

And start to simplify:

81 = 3z

Finally we divide:

27 = z

Therefore, z is 27

6. A tank can hold 50 litres of water. At present, it is only 30% full. How many litres of water shall I put in the tank so that
Illusion [34]

Answer:

30% of the total capacity will be=> 50*30/100 = 15 litres. we are required to fill it upto to 50%. So, 50% of the total capacity of the tank is=> 50*50/100 = 25 litres. therefore, amount of water to be put in the tank to get filled its desired amount is 25-15 = 10 liters.
