Think of this as a fraction. Lets think the fraction is based off of the number "4" 4,8,12,16 Makes the fraction 1\4 (because there's 4 numbers total) then lets add the extra 2 numbers of 4+4.....4,8,12,16,20 ,24 . that makes 1\6. so now all you do is convert the fraction into a percentage.
The Correct Answer Is ----> 50%
in 1980 it was about 20%
in 1990 it was about 30%
about a 10% increase
in 2000 it was just under 40% so almost a 10% increase
so for estimating you can say it is increasing by about 10% every 10 years
so in 2010 you can estimate about 50% are unmarried
Answer:
80 units
Step-by-step explanation:
The area of a trapezoid is 1/2(B1xB2) times h. 8+12 is 20, divided by 1/2 is 10, and 10 times 8 is 80.
Hope this helped!❤
Answer:
13
Step-by-step explanation:
Since x is squared, the inverse operation would be square root. So, the square root of 169 is 13.
We can re-write the equation √(1-x) - 2y = 2 → - 2y = 2 - √(1-x)
→ 2y = - 2 + √(1-x) → and y = [ - 2 + √(1+x)]/2
Tis function "exists" as long as the radical is > or = to zero:
1+x > or = 0 → x>-1
{x ∈ R for x> =0}
