Number of adults = 12
Number of children = 17
Step-by-step explanation:
Step 1:
Let a be the number of adults and c be the number of children
Given that the total admission fees paid is $222
Cost for adults is $10 and cost for children is $6
So we have,
10 a + 6 c = 222
Step 2 :
Total people attending is 29
So, a + c = 29
=> a = 29 - c
Step 3 :
Substituting the value for a in the equation in step 1 ,we have
10( 29-c) + 6 c = 222
290 - 10 c + 6 c = 222
-4 c = 222-290 = -68
=> c = -68/-4 = 17
substituting this value of c in the equation in step 2 we have
a = 29 - 17 = 12
So we have 12 adults and 17 children visiting the zoo.
Step-by-step explanation:
If the die has 6 sides, this will be 10 or under, but there are 2160 ways this can happen
6(3-g)+ 2(11-g)
18-6g+22-2g
-8g+40
24% of the cars were travelling above the speed limit.
Step-by-step explanation:
Given,
Total cars monitored = 25
Cars traveling above the speed limit = 6
Percent of cars traveling above speed limit = ![\frac{Cars\ travelling\ above\ speed\ limit}{Total\ cars\ monitored}*100](https://tex.z-dn.net/?f=%5Cfrac%7BCars%5C%20travelling%5C%20above%5C%20speed%5C%20limit%7D%7BTotal%5C%20cars%5C%20monitored%7D%2A100)
Percent of cars = ![\frac{6}{25}*100\\](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B25%7D%2A100%5C%5C)
![Percent\ of\ cars=\frac{600}{25}\\Percent\ of\ cars=24\%](https://tex.z-dn.net/?f=Percent%5C%20of%5C%20cars%3D%5Cfrac%7B600%7D%7B25%7D%5C%5CPercent%5C%20of%5C%20cars%3D24%5C%25)
24% of the cars were travelling above the speed limit.
