Answer:

PLZ GIVE ME BRANLIEST =)))

1. A scientific notation is where you multiply any number by a power of 10 (negative or positive or neutral).

2. This is incorrect, because 3.825*10^6 is actually 3,825,000. The correct answer is 3.825*10^5.

3a) The power is supposed to be negative, since the number is decreasing, not increasing. It is 4.25*10^-5. 3b) The processes are alike in the way that they all have a number being multiplied by a power of 10. They are all different in the way that some numbers can be decimals, and some powers can be negative powers.

A train travels 68 kilometers in 2 hours, and then 64 kilometers in 3 hours. What is its average speed
skad [1K]
Average speed is the distance traveled by an object in total and divided by the amount of time an object covers the distance. The formula is -
Average speed = total distance traveled / total time taken
                         = 68km+64km / 2 hrs.+3hrs.
                         = 132km / 5hrs.
                         = 26.4km/hr.
Therefore, the train's average speed is 26.4km/hr.

What is 19/25 as decimal
Radda [10]
Well first we need to find how we can turn 25 into 100 
Well one way would be to multiply by 4 
25 x 4 = 100 

Since we multiplied the bottom number by 4 we should multiply the top number by 4. 

So..
19 x 4 = 76

So our new fraction is..
 76 
-----
100

Now we can easily turn this into a decimal. 
76/100 = 0.76 

Answer = 0.76 

Good Luck! :)

Y/2 - 1/5 = 2 - y/3 <br><br>please tell me this asap ​
IRISSAK [1]

Answer:

y=2 16/25

in other words, two and sixteen twenty-fifths

Step-by-step explanation:

y/2-1/5=2-y/3

Move the variables to one side and constants to the other

y/2+y/3=2+1/5

Multiply y/2 by 3/3 and y/3 by 2/2 so that they have a common denominator

3y/6+2y/6=2 1/5

5y/6=11/5

Cross multiply

66=25y

y=66/25

y=2 16/25

HOPE THIS HELPS!!!
