In order to vote on any decision, a club requires the presence of 3/16 of all club members. to be approved, a proposal needs 2/3 of the votes cast. a club has membership of 224. What is the minimum number of votes needed for a proposal to be approved?

Answer:

28

Step-by-step explanation:

Given: In order to vote on any decision, a club requires the presence of of all club members. to be approved, a proposal needs of the votes cast. a club has membership of .

To Find: minimum number of votes needed for a proposal to be approved.

Solution:

Total number of members in club

Minimum presence required for vote on any decision

Minimum presence required for vote

Minimum vote required to approve a proposal

Total vote cast

putting value,

Minimum vote required to approve a proposal

Hence minimum 28 votes are required for a proposal to be approved.

3/16 of 224 is 42.

42 need to show up.

2/3 of the 42 people need to vote Yes to be approved.

2/3 of 42 is 28.

42 need to show up.

2/3 of the 42 people need to vote Yes to be approved.

2/3 of 42 is 28.

A cylinder has a height of 16 cm and a radius of 5 cm. A cone has a height of 12 cm and a radius of 4 cm. If the cone is placed inside the cylinder as shown, what is the volume of the air space surrounding the cone inside the cylinder?

To figure out this problem you need to find the area of the cylinder A= pi r^2 *h

Then find the area of the cone 1/3*pi*r^2 *h

Subtract the two answers

Then find the area of the cone 1/3*pi*r^2 *h

Subtract the two answers

What is the value of a, if a2 – 64 = 0 and a > 0?

A^2 -64 = 0

isolate the a

a² - 64 (+64) = 0 (+64)

a² = 64

√a² = √64

a = √64

a = 8

hope this helps

isolate the a

a² - 64 (+64) = 0 (+64)

a² = 64

√a² = √64

a = √64

a = 8

Damarcus says 24/6 only belongs to the set of rational numbers explain his error

By definition we have to:

Rational number is any number that can be represented as the quotient of two whole numbers or, more precisely, an integer and a positive natural.

We then have the following number:

24/6

Rewriting we have:

24/6 = 4

We observe then that we also have a natural number because it belongs to the set:

ℕ = {1, 2, 3, 4, ...}

Whole number because it belongs to the set:

Z = {..., - 3, -2, -1,0, + 1, + 2, + 3, ...}

Real number because this set covers all the numbers:

Rational, irrational, whole and natural.

Answer:

The error of Damarcus is not to rewrite the number. Therefore, he did not realize that the number does belong to other sets of numbers

Answer:

This is false. 24/6 is equal to 4, so this is also a natural number (counting), a whole number, an integer, and a real number. Also, it's a terminating decimal if ya wanna get technical
