Answer:

The answer would be 5!

Step-by-step explanation:

You start with 1+2i and the conjugate of this would be 1-2i!

After that, in order to find the product, you multiply (1+2i)(1-2i)

You can use distribution or you can use the formula (a+b)(a-b)=a^2-b^2

Either way the answer will be 1-4i^2

i^2=-1 so you replace the i^2 in our equation with negative 1 and solve to get 5!

Hope this helped! <3

240 is 60% of what number?
Brums [2.3K]
Hi there! To find the answer to that question, we can write and solve a proportion. Set it up like this: 240/x = 60/100. This is because we're looking for the whole and we already know the part, which is 240. Cross multiply the values in order to get 24,000 = 60x. Now, divide each side by 60 to isolate the variable. When you do, you get x = 400. You can check this by dividing and then multiplying that quotient by 100. 240/400 is 0.6 and 0.6 * 100 is 60. That makes 60%. There. 240 is 60% of 400.

How to solve this problem<br> -3 1/3 x (-2 7/10)
xz_007 [3.2K]

Answer: 9

Step-by-step explanation:

-3 1/3 x (-2 7/10)

-3  = -3*(3/3) = -9/3

-3 1/3 = -10/3

(-2 7/10)

-2  = -2(10/10) = -20/10

-2 7/10 = -27/10

(-10/3)*(-27/10) = (270/30) = 9
