The guy above me is wrong.

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10.  If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive. So you will not have a negative exponent, because the decimal is moved to the left not the right it will actually be a +6 exponent. Also you only get a negative exponent if it is a small number like .56789 then you'd have a negative exponent, but that is not the case for this problem.  

Your Answer: 5.000039 x 10^6

Answer:

30.96 m^2

Step-by-step explanation:

Side length of the square is also the diameter of the semicircle so:

r = 0.5 * 12 m = 6 m

Since you want the area of the shaded area, you have to subtract the area of both semi circles from the area of the square:

Square Area - Semi Circle Area - Semi Circle Area = Shaded Region Area

(12 m * 12 m) - (0.5 * 3.14 * 6^2 m) - (0.5 * 3.14 * 6^2 m)

= 144 - 56.52 - 56.52

= 30.96 m^2

The height of a triangle is 3cm less than the length of its base and is area is 27m,find the height
Shkiper50 [21]
Area of a triangle=bh/2

27= x(x-3)/2
27= (x^2-3x)/2
54= x^2-3x
x^2-3x-54=0
(x-9)(x+6)=0

x=9, x=-6.
In this case, x must equal 9 since the base cannot be a negative number.

Final answer: Height=6 m

What is a number line for 5a + 18 &lt; -27?
Alexandra [31]

a < -9

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

                    5*a+18-(-27)<0  

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  5a + 45  =   5 • (a + 9)  

Equation at the end of step  1  :

Step  2  :

2.1    Divide both sides by  5  

Solve Basic Inequality :

2.2      Subtract  9  from both sides

           a < -9
