Answer:
<h3>a)a+c=150,10.25a+7.75c=1470</h3>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
- system of linear equation
<h3>let's solve:</h3>
according to the first condition
according to the second condition
1 foot = 12 inches
(1 foot)³ = (12 inches)³
12³ = 1,728 in³
To change 10 cubic feet into cubic inches
10 ft³ * 1728 in³/ft³ = 17,280 in³ Choice C. Multiply by 1,728
Answer:
Step-by-step explanation
Volume of tank = l* b*h
= 18*16*13
=3744 cubic cm
Volume of cylinder = volume of tank
πr²h = 3744
3.14* (17/2)² * h = 3744
h= 3744 *2 *2/*17*17*3.14
h=16.5 cm
