Answer:
Step-by-step explanation:
The specifications of a decagonal pyramid would be the following
It has one face that is a decagon.
35 diagonals in the base.
10 isosceles triangles as faces above the base
11 vertices - 10 in the base and 1 at the top
20 edges - 10 in the base and 10 above the base
This can all be seen in the picture of the decagonal pyramid below. The only decagonal face is on the base of the pyramid as the top is a vertice where all of the triangles meet.
Answer:
Correct answer: True
Step-by-step explanation:
coeff c = 4/3 coeff c₁ = 8/6 when we divide fraction ( or ratio)
by number 2 we get c₁= 4/3
The conclusion is c = c₁ and we can form the proportion
4/3 = 8/6 or 4 : 3 = 8 : 6

Answer:
$927.113
Step-by-step explanation:
50-7=43
43×18.94=814.42
100-15=85
100%=18.94
what about 85%
85×18.94=1609.9÷100=16.099
16.099×7=112.693
814.42+112.693= 927.113
5(v-s)=30 and 3(v+s)=30
5v-5s=30
v-s=6
v=6+s now use this v in the second equation from the beginning...
3(6+s+s)=30
6+2s=10
2s=4
s=2 and since v-s=6, v=6+s=8
So the rate of the boat is 8mph and the rate of the current is 2mph
