Answer:

60.916 inches

Step-by-step explanation:

Given a circle of radius ''R'' the circumference of the circle is calculated as :

C=2\pi R

Where the letter C is the circumference.

In the exercise, the radius is 9.7 inches, replacing this value of R in the equation of circumference and using \pi =3.14 :

C=2\pi R\\C=(2).(3.14).(9.7in)=60.916in

Which graph shows a proportional relationship in which the value of y is one-half of the value of x?
alexira [117]

Answer:

The graph is shown below.

Step-by-step explanation:

Given:

The relationship between the variables 'x' and 'y' is proportional relationship.

A proportional relationship is of the form:

y=mx

Where 'm' is called the constant of proportionality and also the slope of the line y=mx

Now, it is given that 'y' is one-half of the value of 'x'. Framing it in equation form, we get:

y=\frac{1}{2}x

So, the slope of the line is m=\frac{1}{2}

Slope is nothing but rise over run. Run is parallel the x-axis and rise is parallel to the y-axis.

Now, a proportional relationship always passes through the origin.

So, in order to get slope equal to one-half, we need to move 2 units along the x-axis from the origin and then 1 unit parallel to y-axis to get to the next point. The point is (2, 1).

Now, we draw a line passing through the origin and (2, 1) which is the required of the given proportional relationship.

Enter the value of 4 1/4 - 5/7 + (-2/7) - (-3)
swat32

Answer:

=6\frac{1}{4}

Step-by-step explanation:

4\frac{1}{4}-\frac{5}{7}+\left(-\frac{2}{7}\right)-\left(-3\right)

4\frac{1}{4}=\frac{4\cdot 4+1}{4}

=\frac{17}{4}

=\frac{17}{4}-\frac{5}{7}+\left(-\frac{2}{7}\right)-\left(-3\right)

=\frac{99}{28}+\left(-\frac{2}{7}\right)-\left(-3\right)

=\frac{99}{28}-\frac{2}{7}-\left(-3\right)

=\frac{13}{4}-\left(-3\right)

=\frac{13}{4}+3

=\frac{25}{4}

\frac{25}{4}=6\frac{1}{4}

=6\frac{1}{4}

X + 3y =5<br> 2x - 3y =1
IrinaK [193]
1x + 3y = 5
<u>2x - 3y = 1</u>
       <u>3x</u> = <u>6</u>
        3     3
         x = 2
2(2) - 3y = 1
   4 - 3y = 1
<u> -4          -4</u>
      -<u>3y</u> = <u>-3</u>
       -3     -3
         y = 1
   (x, y) = (2, 1)
