Have a nice day.
(x+3 ; y-5)
If you have (-2 ; 3) that means x = -2 and y = 3 so:
(-2+3 ; 3-5) = (1 ; -2)
1.5 cups per day...7 days per week....1.5 * 7 = 10.5 cups per week
16 cups = 1 gallon
16/1 = 10.5/x....16 cups to 1 gal = 10.5 cups to x gal
cross multiply
(16)(x) = (1)(10.5)
16x = 10.5
x = 10.5/16
x = 0.65625 rounds to 0.66 gallons per week
Which is a subset of [1,2,4,5,6]? <br>
A. [0,1,2]<br>
B. [3,4]<br>
C. [5,6,7]<br>
D. [2,6]

Answer: D, [2,6])
Step-by-step explanation
Let us start by explaining what a subset means. A subset of a set is a a set(usually a smaller set) that contains contains elements which are all members or elements of the main set. This means that all the elements in the subset are contained in the main set. Usually, all the elements of the subset are contained in the main set but all the elements in the main set are not contained in the subset
The given set of numbers is
[1,2,4,5,6]
From the options given, all the elements in the subset, [2,6] are contained in the main set, [1,2,4,5,6].
So option D is the subset.
The subsets in the other options has elements that are not in the main set.
Vsphere=(4/3)pir^3
when we replace r with 2r
newvsphere=(4/3)pi(2r)^3
newvsphere=(4/3)pi8r^3
newvsphere=8((4/3)pir^3)
newvsphere=8(vsphere)
it's volume is multipliied by 8
that is choice C, because 2^3=8, it's vollume is 8 times original voluem
answer is C
