60 children tickets and 190 adult tickets were sold.
<u>Step-by-step explanation:</u>
Let the no. of adult tickets sold be 'a'
Let the no. of children tickets sold be 'c'
Total tickets sold = 250
Cost of 1 children ticket = $2.5
Cost of 1 adult ticket = $4
Total money collected= $910
Given that,
a + c = 250
a = 250 - c
4a + 2.5c = 910
Substitute a value
4(250 - c) + 2.5c = 910
1000 - 4c + 2.5c = 910
1000 - 1.5c = 910
-1. 5c = -90
1.5c = 90
c = 90/1.5
c = 60
a + c = 250
a + 60 = 250
a = 190
60 children tickets and 190 adult tickets were sold.
Answer:
x = 2√5 and x = - 2√5
Step-by-step explanation:
x^2 = 20
x = 2√5 and x = - 2√5
To round to the nearest hindered thousand in 235,000 you would underline the number in the ten thousand place. In this case it's 3. Then you look at the number you've underlined and if it is over 5 then you round the miner in front of it up by 1 if it is under 5 then you leave it the same and all the numbers after it becomes zeros
The function is discontinuous at x=8 because as x approaches 8 from the left, f(x) approaches -1 but as x approaches 8 from the right, f(x) approaches 1 and -1 and 1 are not equal.
Answer : The length of an edge of cube is, 10 inches.
Step-by-step explanation :
The formula used for area of cube is:
Area of cube = 
where,
a = edge
We are given that:
Area of cube = ![600in^2[tex]Now put all the given values in the above formula, we get:Area of cube = [tex]6a^2](https://tex.z-dn.net/?f=600in%5E2%5Btex%5D%3C%2Fp%3E%3Cp%3ENow%20put%20all%20the%20given%20values%20in%20the%20above%20formula%2C%20we%20get%3A%3C%2Fp%3E%3Cp%3EArea%20of%20cube%20%3D%20%5Btex%5D6a%5E2)
Therefore, the length of an edge of cube is, 10 inches.
