The cost of one adult ticket is $12 and cost of one child ticket is $8.
Step-by-step explanation:
Let,
Cost of one adult ticket = x
Cost of one child ticket = y
According to given statement;
x+4y=44 Eqn 1
5x+2y=76 Eqn 2
Multiplying Eqn 1 by 5
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 18
Putting y=8 in Eqn 1
The cost of one adult ticket is $12 and cost of one child ticket is $8.

The Sum of all the siblings ages are 36.
Explanation:
Your sister was half your age(3).
Your brother was twice your age(12).
It says 5 years later...
so then your sister is 8
brother is 17
your 11.
When you add all of these ages up you get the answer 36.
a^2 + b^2 = c^2
9^2 + 7^2 = get the answer then find the square root of it
Answer:
/2
Step-by-step explanation:
lets find hypotenuse( longest side) first
let other two samller sides be a and b and hypotenuse be c
pythagorsd theorem
a^2 + b^2 =c^2
9^2 + 2^2 =c^2
81 + 4=c^2
85 =c^2
=c
take theta as reference angle
cosec theta=hypotenuse/opposite
= / 2
Answer:
110 minutes or 1 hour 50 minutes
Step-by-step explanation:
44 divided into 4 since we want to find out how much time it takes to run 1 mile, so 44 divided into 4 is 11
then simply multiply 11 with 10 and the answer is 110
