Mr. Rowley: 16:14 which reduces to 8:7
Ms. Rivera: 64:60 -> 16:15

The measure of an angle is 60° less than nineteen times the measure of its supplement. what is the measure of the angle?

DerKrebs [107]

Two angles are supplementary when they add up to 180 degrees.

x = angle
19x-60 = supplement angle

x + 19x - 60 = 180
20x = 180 + 60
20x = 240
x = 240/20
x = 12° ← answer

Step-by-step explanation:

Step 1: Define

Identify.

Point (-7, 1)

Point (-7, -5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-7 - -7)^2 + (-5 - 1)^2}$
[Order of Operations] Evaluate: $\displaystyle d = 6$

Colin Is buying dirt to fill a garden bed that is a 9ft by 11ft retangle. If he wants to fill to a depth of 4in. How many cubic

OLEGan [10]

1584 yards cubed.

Convert all the measurements to inches.
9*12=108
11*12=132
Multiply 108 and 132 to get the area.
108*132=14256
Multiply 14256 by 4 to get the volume.
14256*4=57024
Divide by 36, because there are 36 inches in a yard.
57024/36= 1584 Yards Cubed
