Answer:
The one on the right
Step-by-step explanation:
Bird is the bigger circle, cardinal is the smaller circle.
If it is a cardinal, then it is a bird.
If it is a cardinal, it must belong to the bird group, so cardinal must be inside birds.
Answer:
240 ml of 1.5% solution and 360 ml of 4% solution should be used.
Step-by-step explanation:
Since a lab assistant needs to create a 600 mL mixture that is 3% hydrochloric acid, and the assistant has solutions of 1.5% and 4% in supply at the lab, to determine the number of milliliters of the 1.5% solution and the number of milliliters of the 4% solution that must be used, the following calculations must be performed:
50 x 0.015 + 50 x 0.04 = 0.75 + 2 = 2.75
40 x 0.015 + 60 x 0.04 = 0.6 + 2.4 = 3
600 x 0.4 = 240
Therefore, 240 ml of 1.5% solution and 360 ml of 4% solution should be used.
Answer:
Step-by-step explanation:
This is an arithmetic sequence
a1 = -2
Difference = 2nd term - first term
![=\frac{-5}{4}-[-2]\\\\=\frac{-5}{4}+2\\\\=\frac{-5}{4}+\frac{2*4}{1*4}\\\\=\frac{-5+8}{4}=\frac{3}{4}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-5%7D%7B4%7D-%5B-2%5D%5C%5C%5C%5C%3D%5Cfrac%7B-5%7D%7B4%7D%2B2%5C%5C%5C%5C%3D%5Cfrac%7B-5%7D%7B4%7D%2B%5Cfrac%7B2%2A4%7D%7B1%2A4%7D%5C%5C%5C%5C%3D%5Cfrac%7B-5%2B8%7D%7B4%7D%3D%5Cfrac%7B3%7D%7B4%7D)
The slope of the line is 2
