Answer: 188 children and 200 adults were admitted
Step-by-step explanation:
Let x represent the number of children that were admitted.
Let y represent the number of adults that were admitted.
On a certain day, 388 people entered the park. It means that
x + y = 388
The admission fee at the amusement park is $2.00 for children and $6.80 for adults. The admission fees collected on that day totaled $1736. It means that
2x + 6.8y = 1736- - - - - - - - - - 1
Substituting x = 388 - y into equation 1, it becomes
2x + 6.8y = 1736
2(388 - y) + 6.8y = 1736
776 - 2y + 6.8y = 1736
- 2y + 6.8y = 1736 - 776
4.8y = 960
y = 960/4.8
y = 200
x = 388 - y = 388 - 200
x = 188
Given:
are in geometric sequences.
To find:
The value of x.
Solution:
If a, b, c are in geometric sequences, then
...(i)
It is given that are in geometric sequences. By using (i), we get
On further simplification, we get
Therefore, the value of x is 0.
No, because 11.3 is like saying 11 and 3 quarters .
X = 5.
Pythagorus Theorem:
c^2 = b^2 + a^2
(13)^2 = (12)^2 + a^2
a = sqrt((13)^2 - (12)^2))
a = 5
One thing is you don't have to put the decimal point before the last two zeros. :D just saying... but if you want to then that's okay.
Anyway doing this scientific notation, you write the number down.
1) 13562600000000.00
Next you write times (x) 10
2) 13,562,600,000,000.00 x 10
Then you write the exponent of the number of places you need to move the decimal. REMEMBER: to make a standard notation to scientific notation the number has to be BETWEEN 1 and 10
3) 1.3562 x 10∧11
It might be 15 for you because you might count the two zeros behind the decimal point in standard form.
I hope this help you out :D
