Answer:
48
Step-by-step explanation:
To solve this we need to do the operations in the brackets first. We should start with the innermost brackets. Then, we work our way outwards. To show my working out I will use an asterisk (*) for multiplication to not confuse X as a variable.
8*{[(7 + 4) * 2] - [(11 - 7) * 4]}
= 8*{[(11) X 2] - [(4) X 4]}
= 8*{[22] - [16]}
= 8*{6}
= 48
The numbers can be arranged in 720 ways.
There are 6 people possible for the first position; 5 for the second; 4 for the third; etc. This gives us 6! = 720.
550+450-120+720=1,600
720/1,600*100%
=720/160%
=45%
therefore, 45% of new balance
Answer:
64
Step-by-step explanation:
The volume of a cubic box with side length of s inches can be calculated using the following formula
If the initial side length was 3 inches and the customer asked Simon to increase each one of the sides of the box by one inch, then the new side lengths now become 4 in (3+1 = 4)
Therefore the final and new volume is
64
Given:
The sequence is 8, 10, 12.5, 15.625,...
To find:
The explicit formula for the given sequence.
Solution:
We have,
8, 10, 12.5, 15.625,...
Here, the first terms is 8.
The common ratio is 1.25. So, the given sequence is a geometric sequence.
The explicit formula for a geometric sequence is:
Where, a is the first term and r is the common ratio.
The explicit formula for the given geometric sequence is:
Therefore, the correct option is A.
