No. Besides, your instructions tell you to estimate. When I estimate I first figure 10%. Then I double the 10%, and tip some amount between. 10% of 23 = 2.30 2.30 * 2 = 4.60 Estimate a number between 2.30 and 4.60

You didn't set up a proportion. And your answer is wrong. First let's estimate the answer. 36% is a little more than 1/3. 3 * 108 = 324 Now the proportion. 36/100 = 108/x Cross multiply and solve for x.

A block of mass m= 3 kg is initially at rest on a horizontal surface. At time t=0, we begin pushing on it with a horizontal force that varies with time as F(t)=βt2, where β= 1.2 N/s2. We stop pushing at time t1=5 s [F(t)=0 for t>t1]. (a) First, assume the surface ...

math question grade 8!!
First off, when you check the measurements, at least read what you wrote before. You had them listed as cm, not m! so, there are 4 walls: 2(4.8)(2.6) + 2(6.8)(2.6) = 60.32 m^2 and the ceiling: (4.8)(6.8) = 32.64 Subtract 5m^2 for the windows (presumably in the walls, not the ...
