Step-by-step explanation:
8) A) acute 9) C) acute 10) D) right 11) B) acute
12) A) straight 13) A) acute 14) D) right 15) C) ∠L
16) B) ∠HIG 17) B) ∠DEC 18) B) ∠K 19) C) ∠G
20) C) ∠KLJ
We know that ,
1. when 0° < θ < 90°, θ is acute.
2. when θ = 90° θ is right
3. when 90° < θ < 180°, θ is obtuse
4. when θ = 180° θ is straight
To write 1/12 as a decimal you would do 1 divided by 12. 1 goes into 12 0 times, giving you a 0 in the ones place. You would the do 120 divided by 12, giving you 10. Therefore, 1/12 as a decimal is 0.10, simplified to 0.1
Volume of the conical tank = 1/3pi*r^2 * h = 1/3pi * (10/2)^2 * 15 = 125pi cubic feet or 392.7 cubic feet = 392.7 * 7.48 gallons = 2937 gallons.
Volume of the hemispherical tank = 2/3pi * r^3 = 2/3pi * (5.5)^3 = 348.5 cubic feet = 348.5 * 7.8 gallons = 2606 gallons
Hence the conical tank will contain more chemicals
