X+y=4000....(1)
10x+6y=340*100⇒5x+3y=17000......(2)
(2)- 3*(1)⇒ 2x=5000⇒x=2500,y=4000-2500=1500
Answer:
0.45 part of the banner is painted orange
Step-by-step explanation:
portion of rectangular banner painted green = 0.75
Portion of green painted part which is now painted orange = 0.60
Hence we can say that
0.6 part out of 0.75 part of total banner is painted orange
mathematically it is
0.6 * 0.75 = 0.45
Thus 0.45 part of banner is painted orange .
Answer:
Amy is correct because a nonlinear association could increase along the whole data set, while being steeper in some parts than others. The scatterplot could be linear or nonlinear.
Step-by-step explanation:
I just took the quiz, I hope this helps :).

hmmm
half life
well, 120 to 60 is half
60=120e^(-0.00043t)
solve for t
divide both sides by 120
1/2=e^(-0.00043t)
take ln of both sides
ln(1/2)=-0.00043t
divide both sides by -0.00043
ln(1/2)/-0.00043=t
t≈1611.97 years
about 1612 years
