What is the circumference of a circle with the radius of 8.2 (round to the nearest hundredth)?

Answers

Answer 1

Answer: C=2piR. C=2(3.14)(8.2). C=6.28(8.2). C= 51.496. But we have to round to the nearest hundredth which is the second place to the right of a decimal. So now C=51.50 (since 49+1=50) :) hope this helps

Solve the inequality: 3. n - 23 < -2.5

Answers

Answer:

$\Huge \boxed{\boxed{\bf{n < 20.5}}}$

Step-by-step explanation:

To solve the inequality $\tt{n - 23 < -2.5 }$ , we want to isolate the variable $\tt{n}$ .

Let's begin by adding 23 to both sides of the inequality:

$\tt{n - 23 + 23 < -2.5 + 23}$

This simplifies to:

$\tt{n < 20.5}$

Therefore, the solution to the inequality is $\bf{n < 20.5}$ .

How many solutions does this system of equations have?2x – 3y = –6
2x – 3y = 9

A no solutions
B one solution
C two solutions
D infinitely many solutions

Answers

no solutions

if you substitute the equations into each other the x's and y's will cancel each other out and you will be left with 9=-6 which isn't true

Final answer:

the correct answer is option A: no solutions.The system of equations has no solutions.

Explanation:

To determine the number of solutions in a system of equations, we need to look at the slopes and y-intercepts of the two equations.

Let's rearrange the equations to the form y = mx + b, where m is the slope and b is the y-intercept.

For the first equation, we have y = (2/3)x + 2. For the second equation, we have y = (2/3)x - 3. Since the slopes of the two equations are the same, but the y-intercepts are different, the system has no solutions.

Therefore, the correct answer is option A: no solutions.
