Answer:

120 = m PR

Step-by-step explanation:

The angle formed outside =1/2(difference of intercepted arcs)

60 = 1/2 (major arc - minor arc)

60 = 1/2 (longPR - short PR)

120 = long PR - short PR

long PR = 360 - short PR since a circle is 360 degree

120 = 360 - short PR - short PR

120 = 360 -2 short PR

Subtract 360 from each side

120-360 = -2 short PR

-240 = -2 short PR

Divide by -2

120 = m PR

Answer:

m(PR) = 120°

Step-by-step explanation:

∠P+∠Q+∠R+∠O = 360° } => ∠O = 180° - 60° = 120°

∠P+∠R = 180°

∠O = m(PR) => m(PR) = 120°

HELP!!! Which function shows a fabric with a price of $1.25 per square yard?

ohaa [14]

Answer:

$y=1.25x$

Step-by-step explanation:

Let us assume that,

x represents the number of sq. yards of fabric and

y represents price of the fabric.

As the unit price of the fabric i.e cost per sq. yard of fabric is $1.25, so for each number of sq. yard of fabric, the cost for that much of fabric will be multiple of 1.25 of that number.

i.e $y=1.25x$

Here, the rate of change is 1.25. So for each increase in x, the amount of increase in y is 1.25

The table along with the graph have been attached below.
