Answer:
4.25
Step-by-step explanation:
if you multiply 3 1/2 x 3 1/2 x 7, you get 85.75 so you subtract 85.75-90 which equals 4.25. and that is you answer hope this helps!!!
Answer:
If A ⊆ B, then A ⊂ B.
If A = B, then A ⊆ B.
If A = B, then A ⊂ B.
Step-by-step explanation:
In set theory '⊂' is the symbol of proper subset and '⊆' is the symbol of subset of a set.
In option (a),
If A ⊆ B
⇒ A ⊂ B or A = B
Thus, If A ⊆ B, then A ⊂ B.
Option a is true.
(b) If A ⊂ B
⇒ A is the subset of B
That is, all elements of A are also the element of B,
But we can not say A = B
Thus, option b is not true.
(c) If A = B
⇒ A ⊂ B and A ⊃ B or A ⊆ B and B ⊆ A ( Because every set is the subset of itself )
⇒ A ⊆ B.
Option c is true.
(d) If A = B,
⇒ A ⊂ B
Option d is true.
(e) If A ⊂ B,
Then we can not say that,
A = B or A ≠ B
Thus, option e is not correct.
Area of circle= 3.14r^2
r= 4
A= 50.27
The answer is 0.023.

7th term is 15 and the fourth term is 9
Common difference: (15-9)/(7-4) = 2
Counting backwards from the fourth term will give us the "zeroth term"
A0 = 1
The closed formula for the sequence is
An = dn + A0
The 25th term is:
A25 = 2(25) + 1
A25 = 51
Hope this helps!
