The liters in the tank when it is filled to a height of 3.70 is  5,580 liters

The liters that needs to be added to 100% capacity is 480 liters

<h3>What is the volume?</h3>

A right circular cone is a three dimensional object has a flat circular base that tapers to a vertex. The volume of a right circular cone is the amount of space in the right circular cone.

Volume of a cone = 1/3(πr²h)

Where:

  • π = pi = 3.14
  • r = radius
  • h = height

Volume of the right circular cone when its filled to a height of 3.70 = 1/3 x 3.14 x 3.70 x 1.20² = 5.58 m³

5.58 x 1000 = 5,580 liters

Volume of the right circular cone when it is full =  1/3 x 3.14 x 4 x 1.20² = 6.03  m³

6.03 x 1000 = 6030 liters

Liters that needs to be added to 100% capacity =  6030 liters - 5,580 liters  = 480 liters

Answer:

v= 7*6/2 *8 (The last one)

Step-by-step explanation:

To find the volume you have to multiply the base and the height which is 7 and 6 and divide it by 2.  Then you multiply the 8.

Written in simplest form, the expression (x^2)(y^2)-9 over 3-xy is equivalent to
Ilya [14]
((x^2)(y^2) - 9) *(3 - xy).

Note difference of two squares:  (a^2 - b^2) = (a-b)(a+b)
(x^2)(y^2) - 9 = (xy)^2  - 3 ^2 = (xy - 3)(xy + 3).    (Take note)

(3- xy) = -(xy - 3).    (Take note of this also)

Your question said:  ((x^2)(y^2) - 9) times (3 - xy),
Don't you think it should be divide? Would solve it as divide.

((x^2)(y^2) - 9) /(3 - xy)  =  (xy - 3)(xy + 3) / -(xy - 3)

                                  =  -(xy + 3).

Answer is (3). Solved it as divide. Using times gives none of the solution among the options.
Cheers.

the mearsure of a triangle are in the ratio 2:3:4 in degrees what is the largest angle in the triangle​
SOVA2 [1]

Answer:

80

Step-by-step explanation:

Since the three angles of a triangle add to give 180°

The the size of the largest angle 4 = 180° ×

                                                      =  180° ×

∴ the size of the largest angle = 80°

In the given the figure above, m∠BAC = 64° and m∠CBA = 56°. Part I: Find the m∠DEC. Part II: Explain the steps you took to arriv
Doss [256]

Answer:

56, see step-by-step.

Step-by-step explanation:

1. AB is parallel to CD.                                1. Given

  BC is parallel to DE.

  m<BAC=64 and m<CBA =56

2. m<BAC + m<CBA + m<BCA =180       2. The angles in a triangle add up to       180

3. 64+ 56+ m<BCA=180 3. Substitution property of equality.

4. 120 + m<BCA=180 4. Addition property of equality.

5. m<BCA=60 5. Subtraction property of equality.

6. BC is a transversal that cuts through parallel lines AB and CD.

6. Def. of transversal.

7. m<CBA = m<BCD 7. If two parallel lines are cut by a transversal, then alternate interior angles are congruent.

8. m<BCA+m>BCD+m<DCE= 180. 8. Angle addition postulate

9. 60+56+m<DCE=180. 9.substitution.

10. 116 + m<DCE =180 10. Addition property of equality.

11. M<DCE =64 11. Subtraction property of equality.

12. DC is a transversal that cuts through parallel line BC and DE.

12. Def of transversal.

13. m<EDC= m<BCD 13. If two parallel lines are cut by a transversal, then alternate interior angles are congruent.

14. m<EDC= 60. 14. Substitution property of equality.

15. m<EDC+m<DCE+m<Dec=180. 15. Angle addition postulate

16. 56+64+m<dec = 180.16 Substitution property of equality.

17. 120+ m<dec = 180. Addition property of equality.

18. m<dec = 60 18. Subtraction property of equality.
