Answer:

B. -20

Step-by-step explanation:

8/d = -12/30

We can use cross products to solve

8 * 30 = d* -12

240 = -12 d

Divide each side by -12

240/-12 = -12d/-12

-20 = d

A __________ contains all the subset of superset. A superset. B proper subset. C null set 2.Positive square root of 1/3 is______
aivan3 [116]

Answer:

i) superset (A)

ii) 0.577 (A)

Step-by-step explanation:

i) A subset is a set which has all its elements contained in another set.

For two sets A and B, if each element of set A is an element of set B, then A is a subset of B.

A superset is a set that houses another set. So if set A is a subset of set B, then B is a superset of A.

Proper subset

For a set (A) to be a proper subset of another (B) every element of A would be in B but there exists at least one element in B that is not in A.

An Empty Set (or Null Set) doesn't have aren't any elements in it. It is empty.

Since every element of the superset is in the superset. Therefore, A superset contains all the subset of superset.

ii) Square root of 1/3 = √⅓

= ± √⅓ = +√⅓ or -√⅓

+√⅓ = +(√1/√3) = +(1/√3)

+√⅓ = +(1/1.7321)

+√⅓ = +0.577

Therefore Positive square root of 1/3 is 0.577 (A)

What is three fourths plus one third plus two sixths
Goshia [24]
You need to get a common denominator. 3/4= 9/12 because 3x4=12 and 3x3=9. you must do the same thing to both sides. 1/3=4/12 because 3x4=12 and 1x4=4.
2/6=4/12 because 6x2=12 and 2x2=4. 9/12+4/12+4/12=17/12, or 1 5/12. You keep the denominator and add the numerators.
