This is equal tio the diameter of the circle formed:-
152 ins = circumference and this = pi * diameter
so the Answer is 152 / pi = 48.4 ins to nearest tenth
48 inches to nearest inch.
If a 12 oz bottle of shampoo lasted for 16 weeks, we have a ratio of 12:16 which can be shortened to 3:4.
Now if we have 18 oz bottle we know that it's 1/2 more than 12 oz bottle, so the ratio will be also 1/2 more. So if it was 12:16, the new ratio will be:
12 + (1/2 * 12) : 16 + (1/2 * 16)
12 + 6 : 16 + 8
18 : 24
It means that 18 oz bottle should last for 24 weeks. Of course the ratio has to stay the same in its lowest form in both situations and as 18:24 can be shortened to 3:4, it proves it's correct :)
2 n/3 would be the closest answer although it looks as if the 2 is supposed to be multiplied by n/3 which would lead me to write it as 2(n/3)
Answer:
- Perimeter of the original Rectangle is
2(4.5+4.3)=2×8.8= <u>17.6</u><u> </u><u>mm</u>
- Side length of the enlarged rectangle is
- Perimeter of the enlarged rectangle
2(24.3+23.22)= 2×47.52= <u>95.04 mm</u>
