-36i^2 because -12 X 3= -36 and i X i = i^2
Lubov Fominskaja [6]3 years ago

-12i×3i=-12×3×i×i
12×3=36 i×i=i²
So in the case of basic algebra, it's 36i²

If i is √-1 then i² is √-1×√-1 which is -1
36×-1=-36

In a crazed neighborhood they are replacing the speed limit signs that give the speed in m/s.
Lilit [14]

Answer:

11 m/s

Step-by-step explanation:

In converting from mph to m/s, the appropriate conversion factor must be used which in this case is 0.44704 m/s.

Thus;

If 1mph = 0.44704 m/s

Then 25 mph = 25 × 0.44704 m/s = 11.176 m/s

A sample of lake water contains 150grams of salt. If 30% of the water sample is salt, find the number of grams the entire sample
hjlf

Answer:

500 grams

Step-by-step explanation:

Let's say that the total number of grams of the sample is x. We know that 30% of x is salt and we also know this quantity is 150 grams. So, we can write this as:

30% * x = 150

Remember that % is simply "out of 100", so 30% = 30/100 = 0.30. Then:

0.30 * x = 150

Divide both sides by 0.30:

x = 500 grams

Hope this helps!
