1) As a start you have 100% of contaminants: so
the 1st filtration you removed 70% & remaining 30%
the 2nd filtration you removed 70% of the 30% (=21%) & remaining (30%-21%)
or 9%
the 3rd filtration removed 70% of the 9% (=6.30%) & remaining (9%-6.3%)
or 2.7%
the 4th filtration removed 70% of the 2.7% (1.89%) & remaining (2.7%-1.89%)
or 0.81%
Follow the same logic for all remaining question.
The correct answer is a & d.
If you find the equation for Annamarie, you get y = 2.75x+ 11.
Using the slope formula to find what Annamarie pays per basket.
(38.5 - 11)/(10 - 0) = 2.75
Annamarie's flat fee is $11 and Bri's flat fee is $5.50

Answer:
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>Andre notices that he is a little taller than Lin, who described her height as h > and 150 h < 160 but andre is also shorter than their math teacher who is 164 centimeters tall. select the two inequalities that describe andress height</em>
Please have a look at the attached photo.
My answer:
Math teacher's height: 164 cm
Let Andre height is :a
We have Heather height: h
<=> h > and 150 h < 160
<=> 150 < h < 160
=> two inequalities that describe Andres height
Hope it will find you well
1/3 ÷ 2 =
1/3 x 2/1. you do this by doing the reciprocal of 2, and then you do KCF ( keep, change, flip,)
keep 1/3 change ÷ to × and flip 2/1 to 1/2.
1/3 x 1/2 = 1/6.
hopefully this helps you
