The perimeter of a regular hexagon (All sides are equal) is 24x +48. Write an expression to represent the length of one side.

Answers

Answer:

4x+8

Step-by-step explanation:

Find the number of sides in a hexagon, which is 6. Take the expression that represents the perimeter of the hexagon, 24x+48, and divide it by 6. The easier way to do this is to multiply this expression by 1/6. Which looks like so, 1/6(24x+48). Which gives you the answer 4x+8.

By the end of the strike, every newspaper company lowered the bundle cost back to $0.50 except the companies that owned the popular newspapers The World and The Journal. They kept the cost of their newspapers at $0.60 per bundle, but they offered to buy back any newspapers that the newsies were unable to sell during the day. These two publishers agreed to pay the same amount the newsies paid them. $0.06 for every 10 papers.

If you were a newsie, would you rather have the newspaper bundle cost less or have the publisher buy back the unsold papers? Explain your answer.

Answers

ANSWER: I would have the publishers buy back the unsold papers

EXPLANATION: because even you are still gaining money if it’s from the people buying them or the publisher buying them back. If you make it cheaper and they still don’t buy you kinda loose money.

Mattress Warehouse is having a sale on all mattresses. A twin and a king-size mattress are similar rectangles, and the ratio of the corresponding sides is 2:3. If the area of the king-size mattress is 108 ft^2
what is the area of the twin mattress?
1.48 ft^2
2.72 ft^2
3.90 ft^2
4.162 ft^2

Answers

Answer:

Number 3

Step-by-step explanation:

Answer:

1. 48 ft²

Step-by-step explanation:

The ratio of sides is

Twin/king = 2/3

The area is the product of two sides so the ratio of the areas is the square of the ratio of the sides:

A(twin) / A(king) = (2/3)²x/108 = 4/9x = 108*4/9x = 48 ft²

1. There are 200 students in the 7th grade. The students were asked to sign up for their favorite field day activity in gym class. A sample showed that 45 students signed up for tug of war, 15 students signed up for the relay race, and five students signed up for the hula hoop contest. What can you predict about field day?

Answers

Answer:

Hope it helps

Step-by-step explanation:

I predict that most of the students that didn't sign up yet, are going to play tug of war. The 45 student that sign up for tug of war are at 22.5%, then for the relay race( 7.5 %) and hula hoop contest is 10 %. But it could change because only 65 sign up, and there 155 students left that has not sign up.

Since the circumference is a little greater than 3 times the diameter, π is a number that is a little greater than 3. Use the symbol π to represent this special number. Pi is a non-terminating, non-repeating decimal, and mathematicians use the symbol π or approximate representations as more convenient ways to represent pi.
π = 3.14 or 227
Find the circumference of the circle in the picture.

Answers

Answer: about 69.54 cm

Step-by-step explanation:

The diameter of a circle is given to be 21 centimetres. The formula for circumference of a circle given the diameter is πd, where d is the diameter and π is constant equal to 3.14... The question tells us to use 3.14, giving us the equation 3.14*21 cm. This multiplication results in 69.54 cm.
