3 tens= 30
7 tenths= 0.7
8 hundredths= 0.08
so 30+ 0.7+0.08= 30.78
Answer:
Step-by-step explanation:
So this is our question
therefore we need to reduce the number of students for the food to be equivalent for 100 days so,
40 days → 150students
<h3> 100 days → </h3>
10.8/12 x 100 = 90%
So he saves 10%
Add the expensive ones that equals 10.80 and then add all them together which gives you £12 you put 10.80 over 12 and multiply by 100 to find the percentage you have and then minus that from 100 which will give you your answer of 10%
Your answer is 13.8 or 14
A^2 + B^2 = C^2
7^2 + 12^2 =C^2
49 + 144 = 193
193=13.8 (Square root 193)
C^2 is 13.8 or 14
