A group of students stood in a circle to play a game. The circle had a diameter of 11 meters. Which measurement is closest to the circumference of the circle in meters?

Answers

Answer 1

Answer:

Step-by-step explanation:

Given that :

Diameter of the circle = 11 cm

To obtain the Circumference ,C ; use the Relation :

2πr

Where ; r = Radius = diameter / 2 = 11/2 = 5.5m

C = 2 * 3.14 * 5.5

C = 34.54 m

The sum of two numbers is 36. The difference of the numbers is 14. What are the numbers? Write your answer as an ordered pair with no
spaces and in this order (smaller number, larger number)

Answers

Answer:

(11,25)

Step-by-step explanation:

36-14 = 22

22/2= 11

11+14 = 25

Answer:

11 and 25

Step-by-step explanation:

The two numbers we'll call x and y.  Let's set up equations to model the situation:

x+y=38

x-y=14

Solving the second one for x,

x=y+14

Plug this into the first equation for x and get:

(y+14)+y=36

2y+14=36

2y=36-14

2y=22

y=11

x-y=14

x-11=14

x=14+11

x=25

help plz solve these equations by completing the square

x square + 12x =1

Answers

Answer:

x = - 6 ± [tex]\sqrt{37}[/tex]

Step-by-step explanation:

Given

x² + 12x = 1

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(6)x + 36 = 1 + 36

(x + 6)² = 37 ( take the square root of both sides )

x + 6 = ± [tex]\sqrt{37}[/tex] ( subtract 6 from both sides )

x = - 6 ± [tex]\sqrt{37}[/tex] ← exact solutions

A = P( 1+r/n) ^ (nt)

P is the amount invested

r is the rate

n is the number of times per year the interest is compounded

t is the number of years

every 6 months is twice a year

so n is 2

Solution:

Answers

Answer:

y=2/3

Step-by-step explanation:

Answer:

(-2,3) x= -2 y=3

Step-by-step explanation:

The first thing you should do is convert both into standard y=mx+b form

For the first equation you subtract 5y and add 11 to both sides to get

13x+11= -5y

you divide by negative 5 to get

-13x/5-11/5=y

For the second equation we subtract 11y and 7 from both sides to get

13x-7= -11y

divide both sides by -11 to get

-13x/11 + 7/11

We then set both equations equal to each other and solve for x

-13x/5-11/5= -13x/11 + 7/11

Add 11/5 to both sides to get

-13x/5 = -13x/11 + 156/55

Add 13x/11 to both sides to get

-78/55x=156/55

Divide and solve for x to get -2

Then plug x = -2 into the original equations to find y

13*-2 + 5y = -11

-26 + 5y = -11

Add 26 to both sides

5y= 15

y =3

How many integers are there that consist of four digits (from 1000 to 9999) where the first digit is a 5 or an 8 and the third digit is not 5 or 8

Answers

Answer:

1600 integers

Step-by-step explanation:

Since we have a four digit number, there are four digit placements.

For the first digit, since there can either be a 5 or an 8, we have the arrangement as ²P₁ = 2 ways.

For the second digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.

For the third digit, since it neither be a 5 or an 8, we have two less digit from the total of ten digits which is 10 - 2 = 8. So, the number of ways of arranging that is ⁸P₁ = 8.

For the last digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.

So, the number of integers that can be formed are 2 × 10 × 8 × 10 = 20 × 80 = 1600 integers
