Since 10 cm is bigger than 1 mm, the scale drawing is bigger
Answer:
y = 23
Step-by-step explanation:
The diagonals of a rhombus are perpendicular bisectors of each other, thus
∠1 = 90° and ∠1 = 4y - 2, so equating gives
4y - 2 = 90 ( add 2 to both sides )
4y = 92 ( divide both sides by 4 )
y = 23
Answer: m = 3.3 mol·58.326 mol = 192 g
Step-by-step explanation: molar mass of substance is
M= (24.31+ 2·1.008 + 2·16) g/mol = 58.326 g/ mol.
Amount of substance n = m/M and mass m = n·M
<u>Equation given</u>: 
- S: distance fallen --> 1279 ft
- t: time taken for the distance fallen
<u>Solve</u>:
Thus it took <u>8 seconds</u> for the thing to fall from the top
Hope that helps!
