Answer: The answer is D. Trapezoid.
Step-by-step explanation: As shown in the attached figure, a rectangular pyramid ABCDE is drawn. We are slicing this rectangular pyramid parallel to the base BCDE at the points F, G, H and I.
We can clearly see from the figure that upper half of the sliced figure will be similar to the pyramid BCDE and the lower sliced figure will be a trapezoid. These are the three-dimensional figures.
Also, the sliced two-dimensional figure FGHI will be a rectangle, because
the pyramid is a rectangular one and so, FI=GH, FG=HI and all the angles are right angles.
Thus, the resulting two-dimensional figure will be a rectagle.
The beginning formula that you start with is y=m(x)+b
after the problem is written into the formula your ready to start.
It should look like this:
26y=-0.4(1)+b
to get the entire formula you've gotta find the
y-intercept or "b"
to start solving multiply the "m" by the "x" A.K.A:
-0.4×1
you should come up with the answer -0.4 since everything multiplied by 1 is still the same thing depending on if its positive or negative
after you've finished solving the multiplication part the equation should look slightly different like this:
26y=-0.4+b
the next step is the get "y" by itself since right now is a variable.
also you should always remember what ever process of simplifying by the same number to get rid of it in a "y=m(x)+b" equation should be done the same to the other side
take a look at the "-" sign in front of 0.4 this would mean that you are going to do the oppisite opperation to cancel it out so you would be adding the same number to either side. after adding the -0.4 to itself that would leave "b" by itself the problem should now look like this:
(26y+0.4)=b
forget about the y for now and focus on the (26+0.4)
you should get 26.4=b
insert this into the original equation of "y=m(x)+b" and this should look like this:
y=-0.4(x)+12.4

Answer:
The answer 3 13/28 < 3 17/30
Step-by-step explanation:
3 13/28 = 97/28
= 3.46 (2d.p)
3 17/30 = 107/30
= 3.57 (2d.p)
3 13/28 < 3 17/30
< = lesser than
> = greater than
Answer:
Pv/rt=n
Step-by-step explanation:
Pv=nrt
divide both sides by rt
Pv/rt=n
