First, let's find all the factors of 81:
81/3=27
27/3=9
9/3=3
3/1=1
So the factors of 81 are 3,3,3,3, (the numbers by which we divided here).
This means we can write down 81 as 3*3*3*3 or
- which is the answer to the question! (three to the power of 4)
Answer: 17/50
Step-by-step explanation:
First, to add fractions, we must find a common denominator, in this case, 100.
Then, we must make the fractions being added all have the common denominator.
So, we must multiply 3/10 * 10/10, which equals 30/100
30/100 + 4/100
Then, just add across the numerator to get 34/100, which can be simplified to 17/50
To complete the square (x+2/5)^2 it would be x^2+(4/5)x+4/25
Answer:
Jonas would pay $30.76 dollars
Step-by-step explanation:
$25.00 + 7% + 15% = 30.7625
So we would have to round it so it would be $30.76.
<h2>
Answer:</h2><h2>
The correct option is d. (i) and (ii)</h2>
Step-by-step explanation:
The total miles covered per day = 45
No of commuting days in a week = 5
Total miles in a week = 45 * 5 = 225
The total amount spent on gasoline = $ 38
Cost of gasoline per gallon = $ 2.48
The number of gallons consumed per week = 
= 15.32 gallons of gasoline per week.
This confirms (ii) statement
The amount spend on gasoline per mile = 
= $0.17
This confirms (i) statement
The number of miles per gallon of gasoline = 
= 14.68 miles
The statement (iii) is false.
