(3,-2)
Step-by-step explanation:
The one highlighted is correct!
Step-by-step explanation:
#12
PQ = 6x + 25
QR = 16 - 3x
PR = 6x + 25 + 16 - 3x
PR = 3x + 41
#1
D = √(-4 - 5)² + (-7 - 2)²
D = √(-9)² + (-9)²
D = √81 + 81
D = √162
D = 9√2
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.
Step-by-step explanation:
it is from minus infinity to infinity
Answer:
4/8
Step-by-step explanation:
To do this, multiply the whole fraction by 4/4 (which is like multiplying by 1/1). So 1/2 x 4/4 becomes 4/8 :)
