Answer:
0.85 kilograms
Step-by-step explanation:
The nearest hundredth can be defined as a place value used when rounding up numbers after the decimal.
The nearest hundredth can also mean rounding up to 2 decimal places.
We are asked to round up 0.845 to the nearest hundredth
The nearest hundredth is the second number after the decimal = 4
The third number after the decimal = 5, hence we add 1 to 4 , making it 5.
Hence:
0.845 kilograms to the nearest hundredth = 0.85 kilograms
100 = 10^2
1000 = 10^3
10000 = 10^4
0.1 = 10^(-1)
0.01 = 10^(-2)
0.001 = 10^(-3)
Now,
100 × 0.1 = 10^2 × 10^(-1)
= 10
Step-by-step explanation:
d = the distance in one direction.
the time t1 it took group 1 was
t1 = d/6 + d/4
and t2 for group 2 moving with speed2 all the way
t2 = (d+d)/speed2
we know
2d = 24 miles
d = 12 miles
t1 = t2
so,
12/6 + 12/4 = 24/speed2
2 + 3 = 24/speed2
5 = 24/ speed2
5×speed2 = 24
speed2 = 24/5 = 4.8 mph
the second group moved with 4.8 mph.
Answer: If you take the square root of a number that is not a perfect square, it is going to be irrational. And then if you just take that irrational number and you multiply it, and you divide it by any other numbers, you're still going to get an irrational number. So square root of 8 is irrational. You divide that by 2, it is still irrational.
