Answer:

Radius = 3

Since radius is half of diameter diameter is 6 because 3 x 2= 6

Now I multiply that by pi so...

6 x 3.14 = 18.84 So 18.84 is our answer.

If 3 3/4 lb. of candy cost $20.25, how much would 1 lb. of candy cost.
Jet001 [13]

3 3/4 lb of candy costs $ 20.25

we have been given a mixed fraction with both whole number and fraction

so lets convert it an improper fraction

3 3/4

3 wholes are equivalent to 3*\frac{4}{4} = \frac{12}{4}

then 3 3/4 is - \frac{12}{4} + \frac{3}{4} = \frac{15}{4}

so 15/4 lbs -- $ 20.25

then 1 lb is -- \frac{20.25}{15/4} = \frac{20.25*4}{15} = \frac{81}{15} = 5.4

therefore 1 lb is equal to $ 5.40

Graph x=4y , x+y=7.0
Marysya12 [62]

The equation of the lines can be plotted on the graph after calculating the coordinates on each line.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have two linear equation:

x = 4y  

x + y = 7.0

To plot the linear equation first we will find the few coordinates to plot on the coordinate plane.

For the equation of line:

x = 4y

x 0 1 2 3 -1 -2 -3

y 0 4 8 12 -4 -8 -12

For the equation of line:

x + y = 7.0

x 0 1 2 3 -1 -2 -3

y 7 6 5 4 8 9 10

Thus, the equation of the lines can be plotted on the graph after calculating the coordinates on each line.
