Answer:
measure of angle 1=180-123=57°[exterior angle is supplementary]
I think the answer is 2 3/5 and 11/5
Answer:
y= −2/3x+−20/3
heart if it helped you brain if im cool
It is in form (x,y) (ususally)
7.5 and 12
there is something called a coordinate system where a line called the y axis runs vertically for infinity and a line perpendicular to it, crosses it. the other line is called the x axis which also extends for infinity
the point where they cross is point (0,0) or the origin
basically the numbers tell you how far you are from the axises
on the y axis, + numbers are up and - numbers are down
on the x axis, + numbers are to the right and - numbers are to the left
7.5=x and 12=y
+7.5 is positive
7.5 means that the point is 7.5 units to the right of the origin in relation to the x axis
12 is positive
12 means that the point is 12 units up from the origin in relation to the y axis
hope this helped. feel free to ask if its too confusing
Answer:
Red Cell is 300 times larger than the virus
Step-by-step explanation:
Size in scientific Notation
- Red Cell = 9 * 10^-6
- Virus = 9 * 10^-8
Procedure.
- Count the number of zeros in the decimal
- Red Cell = 5 ; virus = 7
- And one more to each
- Red Cell = 6; virus = 7
- change the numbers to minus
- Red Cell = -6 ; virus = - 7
- The last row is the powers as shown above.
Answer
9*10^-6/3 * 10^-8
3*10^(-6 - - 8)
3*10^(- 6 + 8)
3^10^2 or 300 times larger
