A man spent 58% of his income and the amount of money left was $210. Find his income​
professor190 [17]

Answer:

500 $

Step-by-step explanation:

\frac{42\%}{210}=\frac{100\%}{x}

\frac{\frac{21}{50}}{210}=\frac{1}{x}

\frac{21}{50}x=210\\

\frac{21}{50}x\cdot \:50=210\cdot \:50\\

x=500

Write 2 as a complex number.
balandron [24]

Answer:

2 + 0i

Step-by-step explanation:

Our real number in this scenario would be 2. And since we don't need an imaginary part because we are just converting 2 by itself, we plug in 0 for the imaginary number.

What is the value of x in the diagram of Circle O below? *
Anestetic [448]

Answer:

60 degrees

Step-by-step explanation:

As we know that a circle is 360 degrees, and as line AB bisects the circle, then the resulting "semi-circle" is 180 degrees. As we know that angle AC is 120 degrees, it's simple subtraction, to find that 180-120 is 60. Therefore, the value of <em>x</em> must be 60 degrees.

Hope this explanation helped!

(-1,3) (3,0) (-1.-2) find perimiter
KATRIN_1 [288]

Answer:

p≈14.5

Step-by-step explanation:

Find the distance between the three pairs first using the distance formula:

\sqrt{(x2-x1)^2+(y2-y1)^2}

Take the first two points, (-1,3)(3,0) and insert the values:

\sqrt{(3-(-1))^2+(0-3)^2}

Simplify parentheses (two negatives makes a positive):

\sqrt{(3+1)^2+(0-3)^2}\\\\ \sqrt{(4)^2+(-3)^2}\\\\\sqrt{16+9}\\  \\\sqrt{25}=5

The distance between the first two points is 5. Use the nest two points, (3,0)(-1,-2) and insert values:

\sqrt{(-1-3)^2+(-2-0)^2}

Simplify parentheses:

\sqrt{(-4)^2+(-2)^2}\\ \\\sqrt{16+4} \\\\\sqrt{20}=4.5

The distance between the nest two point is about 4.5. Use the remaining two points, (-1,-2)(-1,3) and insert values:

\sqrt{(-1-(-1))^2+(3-(-2))^2}

Simplify parentheses (two negatives makes a positive):

\sqrt{(-1+1)^2+(3+2)^2}\\\\\sqrt{(0)^2+(5)^2}\\ \\\sqrt{0+25}\\ \\\sqrt{25}=5

The distance between the last points is 5. Add the distances together to find the perimeter of the triangle:

5+4.5+5\\10+4.5\\14.5

The perimeter is about 14.5.
