D. 5/4 * 12/1 equals 60/4 which is 15 then minus 1 to get 14.
The slope intercept form is y=mx+b
in this case y=-x
y=(-1)x + 0
so the slope m=-1 and y-intercept which is b is 0
Answer:
8 hours
Step-by-step explanation:
14 + 3x =38
-14 -14

x = 8
Answer:
i = right angle
ii = obtuse angle
iii = straight angle
iv = obtuse angle
v = acute angle
Step-by-step explanation:
an acute angle is an angle less than 90 degrees
an obtuse angle is an angle more than 90 degrees
a right angle is an angle equivalent to 90 degrees (looks like two straight lines perpendicular)
a straight angle is an angle equivalent to 180 degrees (looks like a straight line)
a reflex angle is an angle greater than 180 degrees
so, ...
i = right angle
ii = obtuse angle
iii = straight angle
iv = obtuse angle
v = acute angle
9.75 * 1.2 = 11.7
24.5 * .8 = 19.6
11.7+19.6= 31.3 minutes
hope this helped :)
