Carina rode her exercise bike 30 minutes on Monday, 45 minutes on Tuesday, 30 minutes on Wednesday, 60 minutes on Thursday, and
padilas [110]
I am pretty sure the correct solution would be 43.
You would add all the times: 30+45+30+60+50=215
And then you would divide that number by the amount of values: 215/5
This would give you the answer which is 43. Hope this helps!

U= {1,2,3,4,5,6,7,8,}, A={1,4,5,7}, B= {2,5,6,7,}, and C= {3,4,6,7}
choli [55]

Answer:

  a. {1, 2, 3, 4, 5, 6, 7}

  b. {1, 2, 3, 4, 5, 6, 8}

  c. {4, 5, 7}

  d. {1, 4, 5}

Step-by-step explanation:

The union of two sets is the list of elements in either set. The intersection of two sets is the list of elements in both sets. The complement of a set is the list of elements in the universal set that are not in the set being complemented. The complement of a set can be indicated with an apostrophe: A' is the complement of set A, for example.

<h3>a. AU(BUC)</h3>

B∪C = {2, 5, 6, 7} ∪ {3, 4, 6, 7} = {2, 3, 4, 5, 6, 7}

A∪(B∪C) = {1, 4, 5, 7} ∪ {2, 3, 4, 5, 6, 7} = {1, 2, 3, 4, 5, 6, 7}

<h3>b. (AN(BNC))'</h3>

B∩C = {2, 5, 6, 7} ∩ {3, 4, 6, 7} = {6, 7}

A ∩ (B∩C) = {1, 4, 5, 7} ∩ {6, 7} = {7}

(A∩(B∩C))' = {7}' = {1, 2, 3, 4, 5, 6, 8}

<h3>c. (ANB)U(ANC)</h3>

A∩Β = {1, 4, 5, 7} ∩ {2, 5, 6, 7} = {5, 7}

Α∩C = {1, 4, 5, 7} ∩ {3, 4, 6, 7} = {4, 7}

(A∩B)∪(A∩C) = {5, 7} ∪ {4, 7} = {4, 5, 7}

<h3>d. (ANB')U(ANC')</h3>

(A∩B')∪(A∩C') = A∩(B'∪C') = A∩(B∩C)'

(B∩C)' = {6, 7}' = {1, 2, 3, 4, 5, 8}

A∩(B∩C)' = {1, 4, 5, 7} ∩ {1, 2, 3, 4, 5, 8} = {1, 4, 5}

__

<em>Additional comment</em>

In part (d) we made use of De Morgan's law for sets:

  B'∪C' = (B∩C)'

We also made use of the distributive property for sets:

  A∩(B∪C) = (A∩B)∪(A∩C)

The shortest side of an idosceles triangle is 2x+5 inches. The 2 longest sixes are 3 inches longer. The perimeter of the triangl
Rzqust [24]

Answer:

Step-by-step explanation:

In an isosceles triangle, two sides and two angles are equal.

The shortest side of an isosceles triangle is 2x+5 inches. The 2 longest sides are 3 inches longer. This means that the length of each of the longer sides is

2x + 5 + 3 = 2x + 8 inches

The formula for determining the perimeter of a triangle is expressed as

Perimeter = a + b + c

Where a, b and c are the sides of the triangle.

The perimeter of the triangle is 21 inches. Therefore, the equation that can be used to find the length of each side of the triangle is

2x + 5 + 2x + 8 + 2x + 8 = 21

6x + 21 = 21
