483/100=4.83 (as one percent)
4.83x12=57.96
483-57.96=425.04
=425 robberies
Answer:
= The exponent is 12
Step-by-step explanation:
(9.1 × 10^9)(7.5 × 10^2)
When multiplying terms in scientific notation, we multiply the numbers in front and add the exponents
(a* 10^b) (c* 10^d) = ac * 10^(b+d)
(9.1 × 10^9)(7.5 × 10^2) = (9.1*7.5) * 10^(9+2)
=68.25 * 10^11
But this is not proper scientific notation. We can only have 1 number in front of the decimal. We need to move the decimal 1 place to the right. That adds 1 to the exponent.
=68.25 * 10^11 = 6.825 * 10^(11+1)
= 6.825 * 10^12
Answer:
It would take 0.0977 seconds to go 1 meter at that speed
So first I’m going to change the 10 kilometre in miles which is 6.214 miles
Then I’m going to convert 7800 seconds in hours which is 2.16 hours so now the data shows that Trisha biked 8 miles in 2 hours and becca biked 6.214 miles in 2.16 hours
So Trisha was faster than becca
