Answer:
The cost of the dress is $240.
Step-by-step explanation:
With the information provided, you can use a rule of three to find the total cost of the dress as you know that $60 represents 1/4 of the total cost of the dress:
60 → 1/4
x ← 1
x=(60*1)/(1/4)
x=(60)/(1/4)
x=(60*4)/(1)
x=240/1
x=240
According to this, the answer is that the cost of the dress is $240.
The cylinder is a three-dimensional shape, and the base area of the cylinder is 12π square feet
<h3>How to determine the base area?</h3>
The given parameters are:
- Volume = 216π cubic feet
- Height = 18 feet.
The volume of a cylinder is calculated using:
Volume = Base area * Height
So, we have:
216π = Base area * 18
Divide both sides by 18
Base area = 12π
Hence, the base area of the cylinder is 12π square feet

Answer:
3.5x
Step-by-step explanation:
Put into numbers, [4*x+(3x)]*1/2. You cant completely solve for x in this, as we would need an answer with no variable. But, 4*x=4x, and 4x+3x=7x because we would need to combine like terms. But you still need to cut it in half. Half of 7x is 3.5x, so there ya go!
