Answer:

Option 2 -  A\cap B=\{5\}

Step-by-step explanation:

Given : A = {2, 5, 8, 11, 14} and B = {1, 3, 5, 7}.

To find : A\cap B ?

Solution :

The intersection of two sets A and B is the set containing all elements of A that also belong to B and nothing else.

A = {2, 5, 8, 11, 14}

B = {1, 3, 5, 7}

The common elements are 5.

So, A\cap B=\{5\}

Therefore, Option 2 is correct.

Pete has 4 packs of gumballs. Each pack has 5 gumballs. If Pete gives the same number of gumballs to 6 friends, how many gumball
Illusion [34]

Answer: Each friend will get 3 gumballs.

Step-by-step explanation:

Given: Pete has 4 packs of gumballs. Each pack has 5 gumballs.

Total gumballs he has = 4 x 5 = 20

Now , if he needs to divide them into 6 friends , then each friend will get (20 ÷ 6)  gumballs

20\div 6=\dfrac{20}{6}=\dfrac{18+2}{6}=\dfrac{3\times6+2}{6}=3\dfrac26

So each friend will get 3 gumballs.

Choose the algebraic expression that represents the area of a triangle that has a base 8 inches less than 2 times wider than the
loris [4]

Answer:

B. (1/2)(2h-8)(h)

Step-by-step explanation:

Area of a triangle = 1/2 × base × height

Let

Height = h

Base = 8 inches less than 2 times wider than the hight

= 2h-8

Substituting the values of base and height into the formula

We have,

Area of a triangle = 1/2 × base × height

= 1/2 × (2h-8) × h

= (1/2)(2h-8)(h)

The correct answer is option

B. (1/2)(2h-8)(h)

Kay [80]

Answer:

Ethan and Tenaya ate more than half of their pizza.

Sam and Suzy ate less than half of their pizza.

Step-by-step explanation:

We have been given that each of the four friends ordered individual pizzas. They ate some part of the pizzas and we have to find who ate more than half of their pizza? Less than half?

Suzy ate 3/8 of her pizza. It means she ate 0.375 of her pizza which is less than half.

Ethan ate 3/5 of his pizza. It means he ate 0.6 of his pizza which is greater than half.

Tenaya ate 4/6 of her pizza. It means she ate 0.67 of his pizza which is greater than half.

Sam ate 1/3 oh his pizza. It means he ate 0.3 of his pizza which is less than half.

Hence, we can conclude that

Ethan and Tenaya ate more than half of their pizza.

Sam and Suzy ate less than half of their pizza.
