<u>Define x:</u>
Let the cost of the ball be x.
Ball = x
Bat = x + 0.1
<u>The total cost is $1.10:</u>
x + x + 0.1 = 1.1
2x + 0.1 = 1.1
2x = 1
x = 0.5
<u>Find the cost of the bat and the ball:</u>
ball = x = $0.50
bat = x + 0.1 = 0.5 + 0.1 = $0.60
Answer: The ball cost $0.50
Answer:
D
x=-4+2√2 or x=-4-2√2
Step-by-step explanation:
3(x+4)²-24
3(x+4)²=24
(x+4)²=24/3
(x+4)²=8
x+4=√8
x+4=±2√2
x=-4+2√2 or x=-4-2√2
Answer:
207π ft²
Step-by-step explanation:
Given in the question,
diameter of the base = 18 ft
slant height= 14 ft
radius of the base = 18/2
= 9 ft
Formula to calculate the surface area
<h3>A = πrl+πr²</h3>
<em>here l = slant height</em>
<em> r = radius of the base</em>
<em />
plug values in the formula
A = π(9)(14)+π9²
A = 207π ft²
