Answer: 102 children and 41 adults swam at the pool that day.
Step-by-step explanation:
Let x represent the number of children that swam at the public pool that day.
Let y represent the number of adult that swam at the public pool that day.
On that certain hot summer's day, 143 people used the public swimming pool. It means that
x + y = 143
The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $219.75. It means that
1.25x + 2.25y = 219.75- - - - - - - - -1
Substituting x = 143 - y into equation 1, it becomes
1.25(143 - y) + 2.25y = 219.75
178.75 - 1.25y + 2.25y = 219.75
- 1.25y + 2.25y = 219.75 - 178.75
y = 41
x = 143 - y = 143 - 41
x = 102
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 ways
there are 6 ways to move from one corner of a cube to the diagonally opposite corner in three moves
Step-by-step explanation:
Given that;
-It's restricted to three moves.
-It has to move from one diagonal to its opposite diagonal.
-it can only move through the edges.
Hence, in the first move.
We have three(3) different options that is three different possible moves that can lead us to the final destination.
The second move.
We have two (2) different possible moves each
The last move
We have just one(1) possible move.
To get the total possible ways, we will multiply the possible options for each move.
Move 1 = 3 options
Move 2 = 2 options each
Move 3 = 1 option each
3 × 2 × 1 = 6 ways
