Step-by-step explanation:
The radius is always half of the diameter.
Answer:
108 ft²
Step-by-step explanation:
Increasing by 50% means multiplying the original quantities by 1.5, that is
100% + 50% = 150% = 1.5 ( 100% is the original dimensions ), thus
new length = 1.5 × 8 ft = 12 ft
new width = 1.5 × 6 ft = 9 ft
Thus
Area = length × width = 12 × 9 = 108 ft²
Answer:
B. -3d + 47.25
Step-by-step explanation:
Each of them has $15.75
Each spent $d
Amount each still has = 15.75 - d
Therefore, total amount the 3 of them has = 3(15.75 - d) = 3*15.75 - 3*d
= 47.25 - 3d
Which is also am equivalent of -3d + 47.25
The complete balanced chemical reaction is:
<span>C7H16 + 3O2
--> 7CO2 + 8H2O</span>
So 3 moles of oxygen O2 is required for every 1 mole of
C7H16. In the same manner, 3 molecules of O2 is required for every 1 molecule
of C7H16.
Answer:
<span>3 molecules O2 </span>
