Answer:
The number in scientific notation is
Step-by-step explanation:
Given : The approximate distance between our solar system and Alpha Centaur (the nearest star) is 25,000,000,000,000 miles.
To find : Express the number in scientific notation ?
Solution :
The scientific notation is defines ad writing a number into smaller way or writing in terms of powers of 10.
Number - 25,000,000,000,000
It has already 12 zeros and add one zero to place a decimal,
Therefore, the number in scientific notation is
Answer:
m = -3/4
Step-by-step explanation:
Slope = M
Answer:
9.5
Step-by-step explanation:
Well the constant proportionality is 9.5 because that is what makes p directly proportional to a, because when h increases, a increases, and when h decreases, a decreases.
He worked an 8 hour day 3 days.
Let x be the number of 8 hour days he works. Then 10-x is the number of 6 hour days he works.
8x + 6(10-x) = 66
Using the distributive property,
8x + 6*10 - 6*x = 66
8x + 60 - 6x = 66
Combining like terms,
2x + 60 = 66
Subtract 60 from both sides:
2x + 60 - 60 = 66 - 60
2x = 6
Divide both sides by 2:
2x/2 = 6/2
x = 3
There were 3 days he worked 8 hours.
