motikmotik

Answer:

114%

Step-by-step explanation:

okay, so we know he spent 22 minutes on math and 25.08 on spelling.

m=22

s=25.08

so to find a percent, you have to divide s/m

s/m= 25.08/22

s/m= 1.14

because this is a decimal, we have to convert it to a percent

114%

to check the answer, multiply 22 times 114%

the answer is 25.08, so we know we got the right answer.

DochEvi [55]

Answer:

$1 + 2\sqrt{2i}$

Step-by-step explanation:

The expression is presented below:

$= \frac{(5 + \sqrt2i) }{(1 - \sqrt{2i)}}\\\\= \frac{(5 + \sqrt2i) }{(1 - \sqrt{2i)}} \times \frac{1 + \sqrt{2i)}}{1 + \sqrt{2i)}}\\\\= \frac{5 + 5\sqrt{2i} + \sqrt{2i} - 2 }{1 + 2} \\\\= \frac{3 + 6\sqrt{2i} }{3}\\\\= \frac{3(1 + 2\sqrt{2i}) }{3} \\\\= 1 + 2\sqrt{2i}$

The above represents an expression
