The square root of 7 is roughly 2.6
The square root of 8 is roughly 2.8
Hence Euler's number is between
and
.
Area of a square=x^2
where x=1 side
if x=8 then
8^2=8 times 8=64
answer is 64 square feet
Area= Length x width
So....
Length= Area divided by width.
Plug in equation
20 divided by 5= L
L= 4

Answer:
383 children and 361 adults
Step-by-step explanation:
Let's say there are a adults and c children. Since the total number of people was 744, we can write:
a + c = 744
We also know that children's prices are $1.75 per child and adults' prices are $2 per adult. Since the total is $1392.25, we can write:
1.75c + 2a = 1392.25
Now we have a system of linear equations:
a + c = 744
1.75c + 2a = 1392.25
Multiply the first equation by 2:
2 * (a + c = 744) ⇒ 2a + 2c = 1488
Now subtract the second equation from this one:
2a + 2c = 1488
- 2a + 1.75c = 1392.25
___________________
0a + 0.25c = 95.75
c = 383
Plug this in to find a:
a + c = 744
a + 383 = 744
a = 361
There were 383 children and 361 adults.
