Answer:

A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.

DiKsa [7]

Answer:

The equation that closely represents the graph is $\mathbf{y=60x-160}$

Option A is correct.

Step-by-step explanation:

We need to find equation that represents the graph.

We can write equation in slope-intercept form: $y=mx+b$ where m is slope and b is y-intercept.

For finding the equation we need to find slope and y-intercept

Finding slope

The slope can be found using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

From the graph we can find $x_1=0, y_1=-160, x_2=1, y_2=-100$

Putting values and finding slope

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-100-(-160)}{1-0} \\Slope=\frac{-100+160}{1}\\Slope=-100+160\\Slope=60$

We get Slope = 60

Finding y-intercept

Using point (0,-160) and slope m = 60, we can find y-intercept

$y=mx+b\\-160=60(0)+b\\b+0=-160\\b=-160$

Writing the equation

So, the equation for given graph having slope m = 60 and y-intercept b =-160 is:

$y=mx+b\\y=60(x)+(-160)\\y=60x-160$

So, The equation that closely represents the graph is $\mathbf{y=60x-160}$

Option A is correct.

Radius of a circle with a circumference of 50.26

klio [65]

Answer:

16 cm

Step-by-step explanation:

Circumference is equal to 2 pi r.

Isolating r gives us C/2pi = r

50.26/2pi = 8, exactly.

Diameter is equal to 2r, so the diameter is 16 cm.
