Answer:
9 7/8
Step-by-step explanation:
solution by separating parts:
1) rewrite equation with parts separated
= 6 +1/4 + 3 + 5/8
2) solve whole number parts
6 + 3 = 9
3) solve fraction parts
1/4 + 5/8 = ?
- find the LCD of 1/4 and 5/8 and rewrite to solve
LCD = 8
2/8 + 5/8 = 7/8
combining the whole and fraction parts:
9 + 7/8 = 9 7/8

Answer:
A = 156 square feet
Step-by-step explanation:
To find how much plywood Jesse will need to cover all the surface simply means we are to find the surface area.
The surface area of the triangular prism is given by;
A = (2 * (Area of the base)) + (Perimeter of base x height)
Now, area of the base=bh/2
b = 3 ft
h = 4 ft
area of the base = 3*4/2 = 6 ft²
perimeter of the base = L + b + h = 4 + 3 + 5 = 12 ft
height of the prism;h = 12 ft
Thus;
surface area of the triangular prism;
A = (2 * 6) + (12*12)
A = 12 + 144
A = 156 ft²
8 + 1 = 9
8 × 1 = 8
Have a good one!
