So you use 40 gallons of water *PER* day.
Average water use in Dec?
(hint: in math * means multiplication)
Dec. has 31 days
so
40 * 31
1240
Average water use is 1240 gallons
Hope this helps :)
Answer:
55
Step-by-step explanation:
since b is 110, you will have to divide 110 by 2 to find out the answer of c because its a half of b and that leaves you with 55, also a is 55 two
c=55
a=55
d=30
Rational numbers are closed under addition ,multiplication but not closed under division
Rational number
Closure property
assume two rational numbers say x and y. the results of addition and multiplication operations give a rational number we can say that rational number are closed under addition and multiplication . For example
rational number are not closed under division as 1 and 0 are rational number but 1/0 is not defined but it is closed under addition and multiplication
that is 1+0 = 1 closed under addition
1*0 =0 closed under multiplication
but 1/0 is not defined so it is not closed under division
Hence Rational numbers are closed under addition ,multiplication but not closed under division
