Answer:
32 256 cubic inches
18.7 cubic feet
Step-by-step explanation:
4 feet = 4 × 12 = 48 inches
8 feet = 8 × 12 = 96 inches
7 inches = 7 ÷ 12 = 0.583 feet
Volume = length × width × height
V = 48 × 96 × 7 = 32 256 cubic inches
V = 4 × 8 × 0.583 = 18.7 cubic feet

Hi!
The simple explanation is just, since there are half as many cows, then the grain will last two times more.
But here's why. How many times are you going to be feeding the cattle, over 10 days, if you feed them once per day? 60 * 10 = 600, so 600 times.
If you're still feeding them once per day, and there are 30 cows instead, then find how many times 30 goes into 600. 600 / 30 = 20 days. That's a method you can use, no matter what, even if it's, say 50 cattle. You would still get an answer (if it was 50, 600 / 50 = 12, so 12 days).
Hope this helped!
Answer:
a is an element of A; a is a rational number
(a+1) is element of B
Step-by-step explanation:
(a+1) = sup(A), which are the elements of B.
(a+1) + 1 = sup(B)
Recall a+1 = sup(A),
Therefore,
sup(A )+ 1 = sup(B)
sup(B) = sup(A) + 1 ___proved
Sup(A) means supremum of set A. It means least element of another set (say set B), that is greater than every element in set A
Answer:
number o students bought pennants = 18
number of student bought fancy ones=12
Step-by-step explanation:
Let x be the number o students bought pennants
and y be the number of student bought fancy ones
total 30 students
Plain pennants cost $4 each and fancy ones cost $8 each.
Substitute 30-x for y in second equation
Subtract 240 from both sides
divide both sides by -4
x=18
number o students bought pennants = 18
number of student bought fancy ones=12
