Answer:
- A = 10^0
- B = 1/10^1
- C = 1/10^2
Step-by-step explanation:
The expanded form of the number 234.567 written using exponential notation would be ...
2×10² +3×10¹ +4×10⁰ +5×10⁻¹ +6×10⁻² +7×10⁻³
Note that exponents decrease going left to right (or increase going right to left). The exponent associated with the "ones" place is 0.
Apparently, you're supposed to write the negative powers as fractions, so you would have ...
6.19 = 6×10^0 + 1×(1/10^1) + 9×(1/10^2)
Answer:
Step-by-step explanation:
I am going with A......12x + 7y....x = # of adult and y = # of children.....adults cost 12 and children cost 7 <====
B doesn't make much sense....u could say x was for girls and y for boys...but u already know how many there are....so I am not sure what the x and y could stand for.
C does't make much sense either....x would have to be red marbles and y would have to be green marbles...but just like B, u already know how many there are....so not sure what x and y could stand for
D. wrong....because the box containing x 7 oz packages and y 12 oz packages.....12x + 7y....for this one to be correct, it would have to have x 12 oz packages and y 7 oz packages
