Step-by-step explanation:
(7 x 10^*9)(5.6 x 10^*8)
(7000000000)(560000000)
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
If the decimal is moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
The measuring unit is the standard unit of a quantity
The measuring unit of size 0.001 is represented by one millionth circle
<h3>How to determine the unit of base 0.001</h3>
The basic measuring unit in base 7 is given as:
49 circles
The above can be represented as:
Base 7 = 49 circles
Represent the base with n.
So, we have the following rule

For measuring unit 0.001, we have:

Evaluate the square

This means that,
The measuring unit of size 0.001 is represented by one millionth circle

Answer:
9
Step-by-step explanation:
A = B + 2
C = B - 3
A x C = 66
A = Andrew
C = Chris
B = Beatrice
Multiply A and c together
(B + 2) x (b - 3)
b^2 - 3b + 2b - 6
b^2 -b - 6 = 66
b^2 - b - 72 = 0
factors of -72b^2 that add up to - b are -9b + 8b
b^2 + 8b -9b - 72
b (b + 8) -9(b + 8)
b = 9 or - 8
b = 9
Answer:8
Step-by-step explanation: Every time the x goes down, the y goes up 3. Since you are trying to find the y intercept, when setting x to zero you will get 3+5 which equals 8. Hope this helps! (Can I please have brainliest?)
