So, 350 out of 1750
350/1750=
.1828/1
percent is parts out of 100 so x%=x/100
make bottom number 100
0.1828/1 times 100/100 =18.28/100=18.28%

8(-m+3)
Step by step solution :
Step 1 :
Equation at the end of step 1 :
0 - 8 • (3 - m)
Step 2 :
Final result :
-8 • (3 - m)
Let's think:
1 ton ------------ 1000 kilograms
3.2 tons ----------- x kilograms
Multiply in cross
1 . x = 1000 . 3.2
x = 3200
So 3.2t = 3200 kilograms
Answer:
B. The horizontal cross-sections of the prisms at the same height have the same area.
Step-by-step explanation:
<em>Notice that the cone and the pyramid have the same volume. This is important. </em>
This follows the <em>Cavalieri's principle</em> that, for the case of 3 dimensions, as the present case, it states, roughly, that if we have two bodies like the cone and the pyramid, and if we have parallel planes crossing each section, and we always have the same area, these two bodies have the same volume.
In this case, both, cone and pyramid have the <em>same volume</em>, then (reciprocally):
B. The horizontal cross-sections of the prisms at the same height have the same area.
The answer to your question is B.
