Please help with these math problems

1. . The cardinal number of the set {rose, daisy, sunflower, marigold, azalea, orchid, lily, carnation, tulip, violet} is _________.

2.Given the following sets, select the statement below that is true.
A = {r, i, s, k, e, d}, B = {r, i, s, e}, C = {s, i, r}

Select the one that is true A ⊂ B and C ⊂ A
B ⊂ A and B ⊆ A
C ⊆ B and A ⊂ C
C ⊂ B and B ⊆ C
C ⊆ A and B ⊂ C

Without writing them all out, what is the number of subsets of set A = {tongue, ear, mouth, eye, nose, cheek, forehead, neck, shoulder}?


3. Given the following set, select the statement below that is true.
V = {a, e, i, o, u}

i ∈ V
V Ø
e ∉ V
5 ∈ V
v ∈ V

Given these sets:
A = {1, 2, 3, 4}
B = {3, 4, 5, 6, 7}
C = {3, 5, 7, 9}

List the elements of this set
B ∩ (A C)
Do not skip to the answer. Show your work, step by step.

Thank you , this will help me understand and be able to complete the others,,,, again thanks so much, please show me how, and explain steps so I can figure out

1. . The cardinal number of the set {rose, daisy, sunflower, marigold, azalea, orchid, lily, carnation, tulip, violet} is 10.


2.Given the following sets, select the statement below that is true.
A = {r, i, s, k, e, d}, B = {r, i, s, e}, C = {s, i, r}

Select the one that is true
A ⊂ B and C ⊂ A: False! A is not a subset of B.
B ⊂ A and B ⊆ A: True.
C ⊆ B and A ⊂ C: False! A is not a subset of C.
C ⊂ B and B ⊆ C: False! B is not a subset of C.
C ⊆ A and B ⊂ C: False! B is not a subset of C.

Note that if we use both ⊆ and ⊂,
⊂ generally indicates a proper subset (that is, not equal to the whole set)
and ⊆ indicates a subset which may be the whole set.


Without writing them all out, what is the number of subsets of set A = {tongue, ear, mouth, eye, nose, cheek, forehead, neck, shoulder}?

A has 9 elements.
