Answer:
Step-by-step explanation:
In propositional logic and Boolean algebra, De Morgan's laws are a pair of transformation rules that are both valid rules of inference. ... The rules allow the expression of conjunctions and disjunctions purely in terms of each other via negation.
Answer: The volume of a sphere with a radius of 5 cm is approximately 523.33 cm3.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere (V) = 4/3 π radius³
Replacing with the values given and solving for V (volume)
V = 4/3 (3.14) 5³ = 4/3 (3.14) 125= 523.33 cubic centimeters
The volume of a sphere with a radius of 5 cm is approximately 523.33 cm3.

Answer: 1,278
Step-by-step explanation: 2(18x18)+2 1/2(18x14)
p.e.m.d.a.s. 18x18= 324 18x14= 252
2x324= 648 2.5x252=630
648+630 =1,278
Since the shape is a quadrilateral, the interior angles add to 360 degrees. Thus, angle C is 360 - 82 - 92 - 102 = 84 degrees.
Answer:
11.6
Step-by-step explanation:
<u>Solving with steps as below:</u>
- 31*r+1.1*(35−31)*r = 410.64
- 31r + 1.1*4r = 410.64
- 31r + 4.4r = 410.64
- 35.4r = 410.64
- r = 410.64/35.4
- r = 11.6
<u>Answer is:</u> r =11.6
