Answer:
50.80 cm^3
Step-by-step explanation:
the polyhedron is a rectangular pyramid
Volume of a rectangular pyramid = 1/3 x ( width x height x length)
1/3 ( 4 x 5 x 3) = 20 inches
we need to convert inches to cm
1 in = 2.54 cm
20 x 2.54 = 50.80 cm^3
Answer:
41.89
explanation:
the formula for finding the volume of a cone would be pi x r^2 x h/3;
3.14 x 4 x 3.33333333, which equals 41.89.
hope that helps :)
This is a problem you need to solve using logs. When you use logs you can "pull" the exponents down in front of the log to get a new equation that looks like this: 2x^3 + x^2 log 81 = 6x - 3 log 27. Now divide both sides by log 81 and 6x - 3 simultaneously to get (2x^3 + x^2)/(6x - 3) = (log 27)/(log 81). If you do the log math on the right side you get .75. Now multiply both sides by 6x-3 to get 2x^3+x^2 = .75(6x-3). If you distribute that out on the left side you'll get 2x^3+x^2=4.5x-2.25. Now move everything over to the left side and set the whole thing equal to 0: 2x^3+x^2-4.5x+2.25=0. When you solve for x, you are in essence factoring, so do this by grouping: x^2(2x+1)-2.25(2x+1). Now finally factor out the 2x+1 to get (2x+1)(x^2-2.25). You're not done yet though cuz you need to solve each of those for x: 2x+1=0, and x= -1/2; x^2=2.25, and x=+/- 1.5. So all the values for x here are -1/2, 1.5, and -1.5
Answer:
3x^{2}+11-14 hi
Step-by-step explanation:
Husband is in march
wife is after march
we have
b-days are same day
ex march 3 and june 3
also, they fall on the same day of the week
so continuing ex. march 3 wed and june 3 wed
so we just look at the calllendar for days that fall on the same day of the week and have the same nuber and are after march
basically, the easy way to find it is to look at the months and see which months that are after march start on the same day
ex. this year march 1 is on a tuesday
so find other months that start on tuesday
answer is September and December
so the Wife's birthday could be in September or December
