If the radius of a circle is 9 cm, what is the area of the circle?
The diameter of the circle is 100 cm what is the circumference of the circle? (Use = 3.14.)

Answers

Answer 1

Step-by-step explanation:

the formula for the area of a circle is

πr²

plug 9 in for r (radius) to get

3.14 (81) = 254.34 cm² as our area

the circumference is equal to πd , with π being pi and d being diameter.

the circumference is then 3.14(100) = 314cm

1. I like buying minutes of music to download on my MP3 player. The music company
charges a monthly charge of $4.35 per month and charges $.15 per song. How many
songs can I download a month if I only wish to spend $25.00?

Answers

You could buy 137 songs.

25.00 - 4.35 = 20.65 after monthly charge
20.65 / .15 = 137 songs

137 x .15 = 20.55 what you would spend in songs
20.55 + 4.35 = 24.90 total with songs and monthly charge. $0.10 left over

Answers

Answer:

rational

Step-by-step explanation:

Answer:

Rational number

Step-by-step explanation:

The definition of a rational number is "A number such as -3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q." The definition of an irrational number is "All the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers." This means 19/7, and all improper fractions, are rational numbers.

4x - 8 > 32

Step 2: Solve for x

Add 8 on both sides:                    4x > 40Divide 4 on both sides:                x > 10

Here we see that any value x greater than 10 would work as a solution to the inequality.

In triangle XYZ,

Here you are multiplying by 3 then adding 5. When doing the inverse, you would do the opposite.

Start with x. then subtract by 5. Itvwould be x-5.

Then divide by 3. So it would be (x-5)/3 which is 1/3x-5/3 which is D

Step-by-step explanation:

From the question, we were told that a basket ball team six games and in those games, the team won by 8 points, lost by 7, won 9 , won 11 , lost by 3 and won by 6

The mean difference in games scored over the six games would be calculated as the addition of the scores divided by 6

= [8 + (-7) + 9 + 11 + (-3) + 6] / 6

= 24 / 6

i think you meant " two x to the 3rd power" and "5x squared" if that's what you meant, 1. Factor out x^2 from the expression
2. Factor out -4 from the expression
3. Factor out 2x+5 from the expression
4. Use a^2-b^2= (a-b) (a-b) to factor the expression
and you'll get (2x+5) x (x-2) x (x+2)

1. multiply 2 times 3
2. multiply 5 times 2

5. Factor out -4 from the expression
6. you get -4(1+2x)
