Let A (101, 202, 303, 404, 505) and B (101, 404). What is A n B?
Zepler [3.9K]
You should use curly braces instead of parenthesis to indicate set notation. The answer is {101, 404} as these two values are in both set A and set B at the same time. The upside down U symbol means "intersection" which is where the two sets overlap. In terms of a Venn Diagram, you'll have two overlapping circles. In the overlapping region is where 101 and 404 are written. In the region of circle A that is outside of B, you'll have 202, 303, and 505. There is nothing to write in the region of B that is outside of A (since all of B is inside A)

Once again, the answer is {101, 404}

–4b – 5 = 3b + 9 <br><br> I need help pls
Kitty [74]

The value of b in the equation is -2

<h3>What is an algebraic equation?</h3>

An algebraic equation is an expression that consists of numbers, variables with their arithmetic operations.

  • When solving this kind of algebraic equation, we move the like terms to a side and solve for the variable(unknown).

From the given algebraic equation:

-4b - 5 = 3b + 9

By collecting the like terms, we have:

-4b -3b = 5 + 9

-7b = 14

Divide both sides by (-7)

\mathbf{\dfrac{-7b}{-7} = \dfrac{14}{-7}}

x =  -2

Aloiza [94]

Draw a diagram to illustrate the problem as shown below.

Calculate the volume of the empty cone.

V₁ = (1/3)π*(6 in)²*(10 in) = 120π in³

Calculate the volume of the sphere.

V₂ = (4/3)π*(1.5 in)³ = 4.5π in³

The volume that can be filled with flavored ice is

V = V₁ - V₂ = 115.5π in³ = 362.85 in³

Answer:

The volume is 115.5π in³ or 362.9 in³ (nearest tenth)
