Answer:
5.67
Step-by-step explanation:
Let's examine both factors...
1.35 comes from 135, it's 100 times smaller, so this factor would force me to move the decimal point by 2 positions to the left.
4.2 comes from 42, it's 10 times smaller, so this factor would force me to move the decimal point by 1 position to the left.
In total, the decimal point would have to be moved by 3 positions, to the left... so 5,670 would become 5.67
Which is easily verifiable just by looking at the end equation, even without calculating it:
1.35 * 4.2 would give something around 5... not around 50 nor 500.
Answer: 4,560 feet
Step-by-step explanation: because 60 seconds in a minute so 72× 60 = 4,560
Answer:
i think its top right i am not sure
Step-by-step explanation
looks right to me
This question is an example of d = r * t
r = rate
r = 3*10^8 m/s
t = ??
d = 7.5 * 10^6 meters.
Sub and solve
d = r * t
7.5 * 10^6 = 3 * 10^8 * t Divide both sides by 3 * 10^8
7.5 * 10^6 / (3 * 10^8) = t
2.5 * 10^(6 - 8) = t
2.5 * 10^-2 seconds = t or
0.025 seconds = t
