Step-by-step explanation:
we need to find how much 14/70 is equal to ? over 100
100/70=1.42857142857
14x1.42857142857=20
Therefore she drinks 20/100 she drinks before she goes on a ride.
or 20%
Answer:
C. 7/8
Step-by-step explanation:
3 1/2 = 3.5 and she picked 1/4 of that number. I divided 3.5 by 4 and got 0.875. I then turned that into fraction form for 7/8.
The answer is: "
6 
" ;
or, write in decimal form; as: "
6.625 " .
________________________________________________<u>Note</u>:________________________________________________7 - 3/8 = 56/8 - 3/8 = (56 - 3) / 8 = 53 / 8 ;
________________________________________________
= 53 ÷ 8 = "
6 " ;
or, write in decimal form; as: "
6.625 " .

Answer: 23.548
Step-by-step explanation: The thousandths place is 3 places to the right of the decimal point so in this problem, the digit in the rounding place is 8.
The rules of rounding says that if the digit to the right of the rounding place is greater than or equal to 5, we round down but if the digit to the right of the rounding place is less than 5, we round down.
Since the digit to the right of the rounding place, 1, is less than 5, we round down. This means that the digit in the rounding place which is 8 stays the same and we change all digits to the right of 8 to zero.
So we have 23<em>.</em>5480.
Finally, it's important to understand that when rounding decimals, we can drop any zeroes to the right of the decimal point as long as they're also to the right of the rounding place.
This means that 23.5481 rounded to the nearest thousandth is 23<em>.</em>548.
Answer:
$6
Step-by-step explanation:
Set up a system of equations where b is the cost of a book and m is the cost of a movie:
9b + 5m = 124
4b + 21m = 318
Solve by elimination by multiplying the top equation by -21 and the bottom equation by 5:
-189b - 105m = -2604
20b + 105m = 1590
Add the equations together, then solve for b:
-169b = -1014
b = 6
So, the cost of a book is $6
