Answer:
$0.60
Step-by-step explanation:
The costs are:
$0.15 + $0.25 = $0.40
He sells it for $1.25.
The value added is:
$1.25 - $0.40 = $0.85
Answer:
12.4 cm³
Step-by-step explanation:
From the picture attached,
Radius of the circular top of the cone =
= 
Height of the cone = h
Lateral height of the cone = h
By applying Pythagoras theorem in the right triangle of the cone,
l² = r² + h²
6² = 1² + h²
h = 
h = 
Ice cream needed to fill one cone = Volume of the cone
Since, formula for the volume of the cone V = 
V = 
= 6.195
≈ 6.20 cm³
Ice cream needed to fill the two cones = 2 × 6.20
= 12.4 cm³
Therefore, ice cream needed to fill the two cone = 12.4 cm³
Answer:
Step-by-step explanation:
divide 20 by four
20/4=5/1
now 10 and 15 can both be divided by 5 since 5 is the greatest common factor
10/15=2/3
