Answer:

C. Cardinality of set E is equal to that of O

Step-by-step explanation:

We are given that two sets

a set E of non negative even numbers

E={0,2,4,....}

A set O of non negative odd numbers

O={1,3,5,.....}

We have to choose correct option in given options

We know that

Set of non negative even numbers is countably infinite and set of non negative odd numbers is also countably infinite.

Cardinality of countably infinite set=Aleph naught=\chi_0

Therefore, cardinality of E=\chi_0

Cardinality of O=\chi_0

Therefore, the cardinality of set  E is equal to cardinality of set O.

Hence, option C is true.

Felicity's dog eats no more than two cups of dog food per day. Felicity's dog eats at least one-quarter cup more than one-half o
horrorfan [7]

Answer:

\frac{1}{4}+\frac{m}{2}   \leq x\leq 2

x denotes amount of food that Felicity's dog eats

Step-by-step explanation:

Given:

Felicity's dog eats no more than two cups of dog food per day.

Felicity's dog eats at least one-quarter cup more than one-half of the amount Martin's dog eats.

The amount of food that Martin's dog eats is represented by using m

To find: the inequality that represents the situation

Solution:

Amount of food that Martin's dog eats = m

Amount of food that Felicity's dog eats ≤ 2

Also,

Amount of food that Felicity's dog eats \geq \frac{1}{4}+\frac{m}{2}

Therefore,

\frac{1}{4}+\frac{m}{2}\leq Amount of food that Felicity's dog eats ≤ 2

Let x denotes amount of food that Felicity's dog eats.

\frac{1}{4}+\frac{m}{2} ≤ \frac{1}{4}+\frac{m}{2}   \leq x\leq 2

SOMEONE PLEASE JUST ANSWER THIS FOR BRAINLIEST!!!
boyakko [2]

Answer:

y^2 + 8y + 16

Step-by-step explanation:

(6y^2 + 2y + 5) - (5y^2 - 6y - 11) =

The first set of parentheses is unnecessary, so it can just be removed.

= 6y^2 + 2y + 5 - (5y^2 - 6y - 11)

To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.

= 6y^2 + 2y + 5 - 5y^2 + 6y + 11

Now you combine like terms.

= 6y^2 - 5y^2 + 2y + 6y + 5 + 11

= y^2 + 8y + 16

Use prime factorization to reduce the fraction 36/180
laila [671]

Answer:

Step-by-step explanation:

36 = 6* 6 = 2* 3 * 2* 3 = 2*2*3*3

180 = 2 * 2 * 3 * 3 * 5 = 2 * 2 * 3*3*5

\frac{36}{180}= \frac{2*2*3*3}{2*2*3*3*5} =  \frac{1}{5}

Factors that are common will be cancelled
