Answer:
≈ 1800 mm³
Step-by-step explanation:
Volume of the figure above will be given by the formula
Cross section area × length
In this case;
Cross section area will be;
Area of the square + area of the two semi circles
12× 12 + 2(3.14 × 6 ×6/2)
= 144 + 3.14 ×36
= 257.04 mm²
Volume = Cross section area × Length
= 257.04 × 7
= 1799.28 mm³
<u> ≈ 1800 mm³</u>
Set up two equations:
1st: P (for Price family) + J (for Jenkins family) = 45 hours
2nd: 20P + 35J = 1200 liters
Rewrite the first equation as P = 45 – J
Replace P in the second equation:
20(45-J) + 35J = 1200
Simplify:
900 -20J + 35J = 1200
900 +15J = 1200
Subtract 900 from both sides:
15J = 300
Divide both sides by 15:
J = 300/15
J = 20
Jenkins used theirs for 20 hours
Price used theirs for 45-20 = 25 hours.
