Answer:
113.04 (6 + g) / 32
Step-by-step explanation:
We know that the total area of a cone is:
A = Pi * r * (r + g), let g be the generatrix.
The radius is half the diameter, therefore, 12/2 = 6 feet.
Replacing:
A = 3.14 * (6) * (6 + g) = 113.04 (6 + g) square feet.
To know the total number of tiles package, we must divide the area of the cone by the area occupied by a package. So:
113.04 (6 + g) / 32
The problem statement does not have a height or the value of the generatrix therefore it is not possible to calculate the number of packages.
Answer:
The man in the goose cross the river, with the fox and the beans together, he leaves the goose on the other side and goes back across.
The man then takes the fox across the river, and since he can’t leave the fox in the goose together, he brings that goose back.
Again, since the goose and the beans can’t be left together, he leaves the goose and he takes the beans across and leaves with the fox.
He returns to pick up the goose and heads back across the river one last time.
Step-by-step explanation:
8 to 6 is a common differnce is -2
6 to 4 is a common diference of -2
4 to 2 is a common diference of -2
common diffference is -2
an=8-2(n-1) would be the explicit formula
D= half dollars
q= quarters
Half dollars + quarters = 30 coins
d+q=30
Step 1:
Solve for one variable:
d+q=30
Subtract q from both sides
d=30-q
Step2:
Find quantity of each coin
d= $0.50
q= $0.25
0.50d+0.25q= $8.75
Substitute d=30-q for d in this equation
0.50(30-q)+0.25q= 8.75
15-0.50q+0.25q= 8.75
15-0.25q= 8.75
Subtract 15 from both sides
-0.25q= -6.25
Divide both sides by -0.25
q= 25 number of quarters
Substitute q=25 in equation to find d
d+q=30
d+25=30
Subtract 25 from both sides
d=5 number of half dollars
Check:
0.50d+0.25q= $8.75
0.50(5)+0.25(25)= 8.75
2.50+6.25= 8.75
$8.75=$8.75
Hope this helps! :)
