The square below represents one whole.
zaharov [31]

Answer:

6 percent

Step-by-step explanation:

6/100 is shaded. This is the same thing as 0.06. Once I move the decimal two places to the right, I get 6. (I move the decimal place because percents are out of 100, so two decimal places.) This means 6 percent.

What are the roots of this quadratic equation? 3x^2+10=4x
____ [38]

Step-by-step explanation:

The root of an equation is when x=0.

We need to rewrite this as 3x²-4x+10=0.

The quadratic formula is

(-b+or-sqrt(b²-4ac))/2a

so 4+or-sqrt(16-120)/2a

since the sqrt can no be negative this answer will have imaginary numbers.

(4+2i sqrt(26))6 and (4-2i sqrt(26))6

simplified is

x=(2+i sqrt(26))/3 and x=(2-i sqrt(26))/3

300 is 5% of what number
Ber [7]
At first I learned to do these equations as Part÷Whole=Percent÷100
Part(The portion)=300
Whole=X
Percent=5
So now you have
300÷X=5÷100
Set this up as a fraction and cross multiply.
Now you have 30,000=5x
Now divide both sides by 5 and you get x=6,000
6,000 is your answer.
