What's the circumference of a
circle with a radius of 5 inches?
Use 3.14 for n.
C = [?] inches

Answers

Answer 1

Answer:

C = 31.4 inches

Step-by-step explanation:

To find the circumference of a circle, the formula is d(pi), or 2r(pi)

We are given the radius, so let's just plug in the number:

2(5)(pi)

So our circumference would be 10pi

We have to get an approximation here, so we would do 10(3.14)

That would be 31.4 inches

I hope this helps, let me know if you have any questions.

Given:

The graph of a line.

To find:

The coordinates of y-intercept and its coordinate form.

Solution:

We know that, the y-intercept is the point where the graph crosses the y-axis.

From the given graph it is clear that the graph of line crosses the y-axis at point (0,8).

So, the y-intercept is 8.

Therefore, the missing values for the blanks are y, 0, 8, 8 respectively.

Find the solution to the equation algebraically. Check your answer. k - 16 = 4

Answers

Answer:

k= 20

Step-by-step explanation:

You start with this equation:

k-16=4

Add 16 on both sides.

k=4+16

Simply.

k=20

If you want to check your answer, you can just plug 20 into where k is back into the equation:)

Hope this helps!

Hey there!

k - 16 = 4


ADD 16 to BOTH SIDES

k - 16 + 16 = 4 + 16

CANCEL out: -16 + 16 because it give you 1

KEEP: 4 + 16 because it give you the x-value

NEW EQUATION:

k = 4 + 16

k = 16 + 4


SIMPLIFY IT!

k = 20


Therefore, your answer is: k = 20


Good luck on your assignment & enjoy your day!

Krisa divides a number by 10. Then she divides the same number by 50. Which quotient is greater? How can you tell?

Answers

Step-by-step explanation:

the quotient of 10 is bigger than the quotient of 50

The quotient is greater when number is divided by 10.

What is division?

The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups.

Given,

Krisa divides a number by 10

Let the number be x

x/10 = y  

x = 10y                ------(1)

Same number is divided by 50

x/50 = z

x = 50z               --------(2)

By equation (1) and (2)

10y = 50z

y = (50/10)z

y = 5z

⇒ y > z

Hence, quotient when number divided by 10 is greater.

Answer:

Choice 2

Step-by-step explanation:

The downward sloping line has a y intercept of +1 and a slope of -2, hence its equation is y=-2x+1.  Since the shaded region includes some points on the line and above the line, we know that the relation must be >=.  Thus, one of the inequalities must be

y>=-2x+1

The upward sloping line has a y intercept of -2 and a slope of +1, hence its equation is y=x-2.  Since the shaded region includes some points on the line and below the line, we know that the relation must be <=.  Thus, the other inequality must be

y<=x-2
