Answer:
Cost of a slice of cake is $0.80
Step-by-step explanation:
Let the cost of 1 bun be x
Then, cost of 1 slice of cake = (x+0.20)
A/q,
7x + 8(x+0.20) = $10.60
7x + 8x + 1.6 = 10.60
15x = 10.60-1.6
x = 9/15
x = 0.6
Now cost of a slice of a cake = x + 0.20
= $(0.6+0.20)
=$ 0.80
Thank you
Answer:
5338in³
Step-by-step explanation:
Volume of a cylinder = πr²h
r is the radius of the cylinder
h is the height
Given
radius = diameter/2 = 20/2
radius = 10in
Height = 17in
V = 3.14*(10)²(17)
V = 314 * 17
V = 5338n³
Hence the volume of the cylinder is 5338in³
Combine like terms
-6x² + (-x²) = -6x² - x² = -7x²
-7x² + 15x + 4 is your answer
hope this helps
