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.
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.

Fill in the table for this input-output rule:
Answer:
1. 1
2. 2
3. -3
4. 51
Step-by-step explanation:
To do this, in each input number (I will represent the number as x), you have to do the number in the input number, x. You have to divide x by 2, then add 1.
x/2 + 1 would be the answer (this is an example).
1. 1
2. 2
3. -3
4. 51
In the following problems, you will make an inference, or prediction, based on the sample from a population. Write two to three complete sentences.
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?
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.
The perimeter of a regular hexagon (All sides are equal) is 24x +48. Write an expression to represent the length of one side.
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.

How can you write (10²)⁴ as a single power of 10? Show your work.
Answer: 10^8
Step-by-step explanation:
Use the law of exponents
10^2X4
10^8
The expression of a function is such that it involves the input to be present as an exponent of some constant, then such function is called an exponential function. You can write (10²)⁴ as a single power of 10 as 10⁸.
What are exponential functions?When the expression of a function is such that it involves the input to be present as an exponent (power) of some constant, then such function is called an exponential function. Their usual form is specified below. They are written in several such equivalent forms.
Given an exponential expression (10²)⁴, which can be written as a power of 10 using the law of exponents. Therefore, the expression can be written as,
(10²)⁴
Using the exponential property, [tex](10^a)^b = 10^{(a \times b)}[/tex]
= 10⁽²ˣ⁴⁾
= 10⁸
Hence, you can write (10²)⁴ as a single power of 10 as 10⁸.

I really need help i dont understand
Answer:
Explanation below!
Step-by-step explanation:
For the Zero Exponent you basically just get rid of the 0 and solve the problem like you usually would.For Example:
(-3x + 7)°
**Pretend ° is a small zero.
Get rid of the 0Get rid of the parentheses.You're finished with the problem!this is because number with an x like -3x cannot be added or subtracted with normal numbers like 7.
So the answer is basically: -3x + 7
For NonZero Positive None Exponents..This is how they work
Pretend (2) is a exponent.
A Example;
8(2) over 8(2) in your problem.
Apply the exponent.8(2) basically means 8 x 8.
8(3) means 8 x 8 x 8
8(0) means 8 because it's not gonna be multipled to anything. That's why its a 0.
and so on.
8 x 8 gets us 64.
So when we apply the exponent, the problem will transform to 64 over 64
2. Turn the fraction into an equation.
Fractions are turned to division equations. So all we have to do is divide 64 by 64 which gets us 1.
I will explain the rest later because I'm short on time, I hope this small information helps you at least a little!

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.

Answer:
Number 3
Step-by-step explanation:
Answer:
1. 48 ft²Step-by-step explanation:
The ratio of sides is
Twin/king = 2/3The 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 ft²Hi, can someone help me finish this?
