The density of the compound of acetone is equal to 0.791 g/mL. The volume is calculated by dividing the mass given by the density. Mathematically, that is,
v = m / ρ
Substituting the known values,
v = 6.56 g / (0.791 g/mL) = 8.29 mL
Thus, the volume of the acetone is approximately equal to 8.29 mL.
Equation A.
Paul's plumbing: y= 40h+ 90
Perfect plumbing: y= 55h + 60
B:
Pauls plumbing: y= 40(3) + 90.... 310= y
Perfect plumbing y= 55(3) + 60... y= 225

Answer:
cos(25)
Step-by-step explanation:
cosAcosB + sinAsinB = cos(A-B)
cos(20)cos(45) + sin(20)sin(45)
= cos(20-45) = cos(-25)
= cos(25) or 0.906

Since Q is a bisector of PR; This mean PR is divided into exactly two equal parts;
Hence:
Substitute values for PR and PQ
Divide both sides by 2
Solve for 2x
Solve for x
