Answer:
V ≈ 662.68
Step-by-step explanation:
15 div by 2 = 7.5 (Radius)
7.5 x 1.5 = 11.25 (height)
Pi x 7.5^2 x 11.25/3
= 662.68
Answer:
proportional
Step-by-step explanation:
Given:
32 bolts for a total of $12.00
3-inch bolt costing 36 cents or 0.36
4-inch bolt costing 42 cents or 0.42
let x represent 3-inch bolt costing 36 cents
let y represent 4-inch bolt costing 42 cents
x + y = 32
0.36x + 0.42y = 12
x = 32 - y
0.36(32-y) + 0.42y = 12
11.52 - 0.36y + 0.42y = 12
-0.36y + 0.42y = 12 - 11.52
0.06y = 0.48
y = 0.48/0.06
y = 8
x = 32 - y
x = 32 - 8
x = 24
James bought 24 pcs of the 3-inch bolt and 8 pcs of the 4-inch bolt.
To check
<span>0.36x + 0.42y = 12
</span>0.36(24) + 0.42(8) = 12
8.64 + 3.36 = 12
12 = 12
Answer:
