Answer: The total cost of 15 carnival tickets=$37.50
Step-by-step explanation:
We are given that ,
The equation 
represents the total cost of buying buying carnival tickets , where x= Number of carnival tickets and y= Total cost.
To find : The cost of 15 carnival tickets.
In the given equation , we substitute the value of x = 15 we get
Thus , According to the equation, the total cost of 15 carnival tickets= $ 37.50
Hence , the correct answer is $ 37.50 .

3 z + 1 + 5 + 7 z [Remove parentheses]
10z + 5 [Combine like terms]
Correct question is;
Terry is filling spherical water balloons with a faucet that puts out 100 cm³ of water per second. At that rate, it takes Terry 6 seconds to fill a balloon. What is the radius of a filled balloon?
Answer:
r = 5 cm
Step-by-step explanation:
Volume of a sphere is;
V = (4/3)πr³
It takes 6 seconds to fill the balloon when a faucet that puts out 100 cm³ of water per second.
Thus,
Volume of balloon = 100 × 6 = 600 cm³
Thus;
(4/3)πr³ = 600
r³ = (600 × 3)/4π
r³ = 143.239
r = ∛143.239
r = 5.23
Approximation to the nearest whole number gives; r = 5 cm
Answer:
A. $3.63
Step-by-step explanation:
You can choose the correct answer simply by estimating.
The almonds are about $5.50 for each of the 2 kg, so will total about $11. Since the total amount paid is just over $25, the amount paid for cashews is about $25 -11 = $14.
That amount pays for 4 kg of cashews, so 1 kg will be half of half that amount, or about $3.50 -- certainly, less than $7.26.
_____
If you want to write an equation, you can write ...
2(5.49) +4(c) = 25.50
4c = 14.52 . . . . . . . . . . . . subtract 10.98
14.52/4 = c = 3.63 . . . . . divide by the coefficient of c
1 kg of cashews has a price of $3.63.
