Answer:
J = 32
E = 0
Step-by-step explanation:
E is the number of hours for the Escobar family
J is the number of hours for the Johnson family
E + J = 32
E * 20 + J * 30 = 960
Multiply the first equation by -20 so we can use elimination
-20 E -20 J = -640
Add this to the second equation
E * 20 + J * 30 = 960
-20 E -20 J = -640
---------------------------------
10 J = 320
Divide by 10
J = 32
Now find E
E + J = 32
E + 32 = 32
E = 0
Answer:
Volume of cone = 234.45 cm³
Step-by-step explanation:
Given:
Diameter = 8 cm
Radius r = 8 / 2 = 4 cm
Height h = 14 cm
Find:
Volume of cone
Computation:
Volume of cone = (1/3)πr²h
Volume of cone = (1/3)(3.14)(4)²(14)
Volume of cone = 234.45 cm³
