Answer:
Step-by-step explanation:
Explanation:
The product of two positive numbers is always positive.
So product of All positive numbers will be always positive.
For Example
( + ) × ( + ) = ( + )
The product of two negative number is always positive.
So product of even negative numbers will be always positive
For example
( - ) × ( - ) = ( + )
Also product of negative and positive is also given as a negative
( - ) × ( + ) = ( - )
and
( + ) × ( - ) = ( - )
Let the Six Positive numbers be
a, b ,c , d, e, f
So the Product of Six Positive numbers will be
![(+a)\times (+b)\times (+c)\times (+d)\times (+e)\times (+f)=\textrm{Positive Number}](https://tex.z-dn.net/?f=%28%2Ba%29%5Ctimes%20%28%2Bb%29%5Ctimes%20%28%2Bc%29%5Ctimes%20%28%2Bd%29%5Ctimes%20%28%2Be%29%5Ctimes%20%28%2Bf%29%3D%5Ctextrm%7BPositive%20Number%7D)
Let the Six Negative numbers be
-a, -b ,-c , -d, -e, -f
So the Product of Six Negative numbers will be
![(-a)\times (-b)\times (-c)\times (-d)\times (-e)\times (-f)=\textrm{Positive Number}](https://tex.z-dn.net/?f=%28-a%29%5Ctimes%20%28-b%29%5Ctimes%20%28-c%29%5Ctimes%20%28-d%29%5Ctimes%20%28-e%29%5Ctimes%20%28-f%29%3D%5Ctextrm%7BPositive%20Number%7D)
Therefore the Product's Sign will be
a) Positive ; Positive
Answer:
65 i think
Step-by-step explanation:
10-7=3 so his rate is 18 boxes every 3 hours 18/3 is 6 boxes per hour, 12-7=5 hours 5 x 6 = 30 boxes by 12pm
X=adult tickets
2x=student tickets
x+2x=306
3x=306
x=102 adult tickets
2x=2*102=204 student tickets

Useful Information:
The formula for compound interest is: ![\sf{amount*decimal^{{No. calculations}}](https://tex.z-dn.net/?f=%5Csf%7Bamount%2Adecimal%5E%7B%7BNo.%20calculations%7D%7D)
Step-by-step explanation:
This is an example of compound percentage increase.
To work this out, you would first have to convert the percentage into a decimal. You can do this by dividing the percentage of 3% by 100, this gives you 0.03. This is because percentages are out of 100 and so dividing the value by 100 gives you the percentage as a part of 1.
The next step is to add 1 to 0.03, this gives you 1.03. This is because you are working out the percentage increase.
The penultimate step is to work out the number of times that the new amount would need to be calculated. This can be done by multiplying 2 by 2, which gives you 4. This is because it will be compounded semiannually, which is twice a year.
The fnal step is to work out the total amount you would need to multiply the amount of 4,500 by 1.03 to the power of 4, this gives you 5064.79 (2 D.P). This is because you are working out 3% of the amount, and then adding it to the new amount and then finding 3% of that amount, and so on.
1) Divide 3% by 100.
![\frac{3}{100}=0.03](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B100%7D%3D0.03)
2) Add 1 to 0.03.
![1+0.03=1.03](https://tex.z-dn.net/?f=1%2B0.03%3D1.03)
3) Multiply 2 by 2.
![2*2=4](https://tex.z-dn.net/?f=2%2A2%3D4)
4) Multiplly 4500 by 1.03 to the power of 4.
![4500*1.03^{4}=5064.79 (2 d.p)](https://tex.z-dn.net/?f=4500%2A1.03%5E%7B4%7D%3D5064.79%20%282%20d.p%29)
