How much was he paid per hour
Answer:
The length of the other side is 7.65m
Step-by-step explanation:
Maria's mistake was that she wanted to move the decimal point 2 places to the left, when she should have moved it 1 place, since that is the number of zeros that the number 10 has.
To find the length of the rectangle, we simply divide the area by the width
a = area = 76.5 m
w = width = 10m
l = length
l = a/w
l = 76.5m² / 10m
l = 7.65m
The length of the other side is 7.65m

Answer:
5.4×10^-1
Step-by-step explanation:
An adjustment in the exponent is needed to get to scientific notation at the end.
(9×10^5)(6×10^-7) = (0.9×10^6)(6×10^-7) = (0.9×6)×10^(6-7)
= 5.4×10^-1
_____
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
_____
Of course, it can be useful to understand how moving the decimal point changes the exponent:
9 = 0.9×10 = 0.9×10^1
Answer is B. 25 per half hour so 50 per hour, therfore 50 x 3 hours = 150
