The store sold 1 and 2/5 more on Friday then Saturday.
Explanation:
6 1/5 - 4 4/5 = 1 2/5
110
2 and 5 are prime and thus share no common factors. The lowest common multiple of 2 and 5 is therefore 2 x 5 = 10.
Your answer must be a multiple of 10 and there is only one answer in that range that fits.
Double-check:
110 / 2 = 55 r. 0
110 / 5 = 22 r. 0
Answer:
25 feet by 12 feet
Step-by-step explanation:
Width of deck = w
Length of deck = 2w + 1---------------------------- (1)
Length of railing = w + w + 2w +1
= 4w + 1---------------------------------- (2)
Length of railing = 49
Solving equation (2)
4w + 1 = 49
4 w = 49-1
4w = 48
w = 48/4
w = 12
Substituting into equation (1)
Length of deck = 2 (12) + 1
= 24+1
= 25 feet
Width of deck = 12 feet
The dimension of the deck = l x w
= 25 feet by 12 feet
NB: The railing comprises two widths of the deck , plus one length of the deck since the other length is attached to the house.
If the whole diameter of sphere is 6 inch(means radius is 3 inch) & thickness of material is 1 inch, so the radius of the hollow part should be 2 inch (3-1=2)
The total volume of the ball will be;
= Total volume - Volume of hollow part
= 4/3πr³ - 4/3πr³
= 4/3 × 3.14 × (3)³ - 4/3×3.14×(2)³
= 4 × 3.14 × 9 - 4/3 × 3.14 × 8
= 113.04 - 33.52
= 79.52
If the density of the material is 3.25 g/in3, then the density of 79.52 inch³ should be;
= 79.52 × 3.25
= 258.44 g
Now, if there are 8 spheres in one box, the weight if box will be;
= 258.44 × 8
= 2,067.52 g
