The answer for this question is= 46.5
What is 155 percent of 30 is 46.5.
It's all from the knowledge.
Your answer is 3.2 x 10^6
The formula is:
<span>a x 10^b</span>
Follow the steps below to see how 3,200,000 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
<span>Original Number: 3,200,000
New Number: 3.2
</span>Step 2
To find b, count how many places to the right of the decimal.
<span><span>New Number: 3.2
</span></span>
There are 6 places to the right of the decimal place.
Step 3
a = 3.2
b = 6
Now the whole thing:
<span>3.2 x 10^6</span>
Hope this helps!!
Answer:
y = 6x+1 . . . . . y ≠ 0
Step-by-step explanation:
Multiplying by y gives the linear equation ...
(1+y)/2 -(3x +1) = 0
1 +y = 2(3x +1) . . . . . add (3x+1), multiply by 2
y = 6x +1 . . . . . . . . . . eliminate parentheses, subtract 1
There are an infinite number of (x, y) pairs that will satisfy this equation. The above equation gives the required relation between the x and y values. The equation is undefined for y=0, so that is not a solution.
Answer:
2nd Choice
Step-by-step explanation:
1 week, according to the graph on 1 x axis (weeks) the y axis (tests taken) reaches 10
-2x+1=-x^2+4
X^2 - 2X + 1 - 4 =0
X^2-2X-3=0
discriminant= (-2)^2 - 4(-3)(1)
=16
D1 = {-(-2)+√16}/2
D1=(2+4)/2
=6/2
D1=3.
D2={-(-2)-√16}/2
=(2-4)/2
=-2/2
D2= -1
the solutions are {-1 ; 3 }
so A) x= -1,3
