Answer:
$7 per cupcake
Step-by-step explanation:
A unit rate is the cost of one item. So we would do $168 divided by twenty-four. That would be equivalent to seven.
It should be -6
8(8-9)+2
Step-by-step explanation:
The angle of depression is
tan^-1 3/7 = 23.2 deg
The angles opposite equal sides are also equal. The sum of angles in a triangle is 180. So 2x + 27 + 2x + 27 + 3x + 28 = 180.
7x + 82 = 180
7x = 98
x = 14
Now plug x into each angle to find their measures.
Answer:
1 and 3 are both perpendicular to segment NY
Step-by-step explanation:
1. Find the slope of line NY
slope of NY = 5-(-7)/-11-5 = - 3/4
Any line that is perpendicular to NY should have a slope of the inverse of negative slope of NY.
2.Find the slope of perpendicular lines
the inverse of negative slope of NY = - (-4/3) = 4/3
