Answer:
192 children and 145 adults were admitted.
Step-by-step explanation:
Let c represent the amount of children and let a represent the amount of adults.
Total fees for children = (Fee for one child) x (Amount of children) = 6.5c
Total fees for adults = (Fee for one adult) x (Amount of adults) = 15a
Total fees = Total fees for children + Total fees for adults
3423 = 6.5c +15a
We know that the amount of people who entered the park was 337. Therefore a+c=337, which means a=337-c.
Sub this in to the equation above to get:
3423 = 6.5c +15 (337-c)
3423 = 6.5c + 5055 - 15c
-1632 = -8.5c
c = 192
So there were 192 children.
Since a=337-c and c=192, a=337-192=145. So there were 145 adults.
Answer:
300
Step-by-step explanation:
Is means equals and of means multiply
18 = 6% * N
Change to decimal form
18= .06N
Divide by .06 on both sides
18/.06 = .06N/.06
300 = N
The number is 300
Answer:
Altogether James walked 
miles.
Step-by-step explanation:
The question involves mixed fractions. Mixed fractions are first converted into proper fractions and then any operation can be performed on them.
Given
Distance of first walk = 
of a mile
Distance of second walk = 5/7
In order to find how much he walked altogether, we have to find the sum of both fractions.
Hence,
Altogether James walked miles.
Answer:
4,243 cm^3
Step-by-step explanation:
In this question, we are asked to calculate the amount of gift wrap needed to cover the box.
This is indirectly telling us to calculate the volume of the triangular prism.
Mathematically, the area of a triangular prism is the area of the base multiplied. y the height.
Area of the base is 1/2 * 12 * 10.4 = 62.4 cm^2
The volume is thus 62.4 * 68 = 4,243.2 cm^3
