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
Given a quadratic equation

1. the first thing we do when we want to compete the square, is write the coefficient of x as 2 times a number.
In our case the coefficient of x is 10, so we write 10 as 2*5
2. then we write +

and -

to the expression:

Answer:
EA
Step-by-step explanation:
We call x the 4 points-worth problems and y the 3 points-worth problems
You know that x+y = 32
4x+3y = 111
You know that the difference from the x and y is 32 so write:
x = 32-y
Substitute at x the value of 32-y
4(32-y)+3y = 111
128-4y +3y = 111
-4y+3y = 111-128
-y = -17
y = 17
