You have learned that calculating relative change of a quantity gives you the percentage increase or decrease. Use the Median New House Cost graph to estimate the
percentage increase in new housing prices from 1999 to 2007. (Choose the best answer.)
O The prices increased from around $160.000 to around $220,000, about a 38%
increase.
The prices increased from around $160,000 to around $220,000, about a 35%
increase.
The prices increased from around $160,000 to around $245,000, about a 65%
increase.
The prices increased from around $160,000 to around $245.000 about a 53%

the probability that a bird is green (.30) is true

step-by-step explanation:

the answer is b.

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
