Answer:

The solution is 40.

n(D U M) = n(D) + n(M) - n(D ∩ M)

= 30 + 20 - 10

= 40 students

What is the most logical first step in solving the equation x2 + 6x +9 = 10?
Shalnov [3]

Answer:

<u>D</u>

Step-by-step explanation:

The logical step is to <u>factorize the left side of the equation</u>, which becomes:

  • (x + 3)² = 10

Then, you can take the square root on both sides.

  • x + 3 = ±√10
  • x = ±√10 - 3

Not asked, but good to understand the procedure regardless.

A gumball is approximately spherical and has a diameter of 1 inch. What is the approximate volume of the gumball? A gumball is a
KatRina [158]

The approximate volume of the spherical gumball is: C. 0.5236 in.³.

<h3>How to Determine the Volume of a Spherical Shape?</h3>

If a shape is spherical, it means it has a shape of a sphere. To determine the volume of the spherical shape, we would use the formula for the volume of a sphere, which is given as:

Volume of a sphere = 4/3 × π × r³, where r (radius of the sphere) is half of the diameter of the sphere.

Given the following parameters of the sphere as:

Diameter of sphere = 1 inch.

Radius (r) = 1/2(1) = 0.5 inch.

π = 3.14

To find the approximate volume of the spherical gumball, substitute the value of r into 4/3 × π × r³:

Volume of the spherical gumball = 4/3 × 3.14 × 0.5³

Volume of the spherical gumball = 4/3 × 3.14 × 0.125

Volume of the spherical gumball = (4 × 3.14 × 0.125)/3

Volume of the spherical gumball = (1.57)/3

Volume of the spherical gumball = 0.523 in.³

Therefore, we can conclude that the approximate volume of the spherical gumball is: C. 0.5236 in.³.
