The |...| means absolute value meaning everything inside is a positive number. The first problem is 16+12= 28. |-5|= 5
24 * 5 = 120
120 + 6 = 126 - total cost - meals and service
6/126 *100% = 4,76%
service charge was 4,76% of total costs.
75.4
12 would be considered the radius
C = 2 pi R
so just insert that into the formula and the answer should be
75.39 but if you round up it would be 75.4

Answer:
The answer is 61.4 L
Step-by-step explanation:
Using the formula of cuboid, V = l×b×h, to find the total amount of water contained :
l = 120cm
b = 40cm
h = 15cm
V = 15×120×40
= 72 000cm³
= 72 L
It is given that she uses 10.6L for shower. Then calculate the remaining water by substracting 10.6L from the original amount of water :
remaining = 72 - 10.6
= 61.4 L
