Answer:
D
Step-by-step explanation:
First, remove parenthesis:
8(x + 30) = 8*x + 8*30 = 8x + 240
Then, add the 5 at the end:
8x + 240 + 5 = 8x + 245
Volume of one pyramid = 408.6*(755.9*755.9)*1/3
volume of 3 pyramids= 3*408.6*(755.9*755.9)=700,403,500.11*1/3=233,467,833.37
reasoning 3 square base pyramid = 1 cuboid
Step-by-step explanation:
(72)¹⁴³ ≡ x (mod 7)
Since 72 ≡ 2 (mod 7),
72³ ≡ 2³ (mod 7) ≡ 1 (mod 7).
Therefore (72)¹⁴³ = (72³)⁴⁷ * (72²)
≡ 1⁴⁷ * 4 (mod 7) ≡ 4 (mod 7).
The answer is A.
Ok so you spent 19 dollars the difference between prices is 5 dollars and your answer would be 12 and 7. If you need any help let me know.
Answer:
x = 4
8(4) - 2 = 30
15(4) = 60
All triangles equal 180 degrees and there is already a right angle. 60 plus 0 is 90, and 90 plus 90 (or 90 times 2) is 180
60 + 30 = 90
90 + 90 = 180
