Answer:
3 ft
Step-by-step explanation:
A cube is made of 6 equal faces each of which is a square with the same side length. The surface area of the cube is the surface area of one side multiplied by 6. We know the surface area is 54 so divide this by 6.
54/6 = 9 ft^2
Since the surface must be a square, take the square root of 9 which is 3 ft. The length of one edge of the cube is 3 ft.
Answer:
70 x 12 1/2 = 875.
Step-by-step explanation:
Step 1.) When you multiply fractions, you put whole numbers over one.
Step 2.) Then, you change whole numbers with fractions, to improper fractions.
Step 1.)
70/1 x 12 1/2
Step 2.)
70/1 x 25 / 2.
And then we solve!
70 x 25 = 1750
1 x 2 = 2.
1750 divided by 2 = 875.
Hope this helps!!

Answer:
Wrong
Step-by-step explanation:
The student is wrong. Two angles are coterminal if and only if the difference between their measures is a multiple of 360°.
The difference between the angles 180° and –180° is 360°, and they are coterminal. Therefore the student is WRONG.
