Answer:
b. 0.86, 0.87
Step-by-step explanation:
a. Refer to the attached solution for part a
The conversions yield 45/60 and 10/60 since the common denominator is established as 60, thus 3/4 of an hour equals 45 minutes and 1/6 of an hour translates to 10 minutes.
Answer:
The transformation is a reflection over the x-axis followed by a translation 6 units left and 2 units down.
Step-by-step explanation:
To determine the order of transformations from ΔABC to ΔA"B"C", note that the figure first changes to ΔA'B'C', and then to ΔA''B''C''.
The transition from ΔABC to ΔA'B'C' involves a reflection over the x-axis, as ΔA'B'C' appears as a mirror image flipped vertically.
Next, moving from ΔA'B'C' to ΔA''B''C'' entails shifting the figure left by 6 units and downward by 2 units. This matches a translation by -6 in the x direction and -2 in the y direction.
Thus, the accurate description is:
Reflection across the x-axis followed by a translation of -6 units in x and -2 units in y.
Answer:
The range of cheerleaders' heights lies within the interval [58, 74)
It includes all real numbers from 58 inches and above, but below 74 inches.
Step-by-step explanation:
we have
Separate the combined inequality into two distinct inequalities
-----> inequality A
-----> inequality B
Solve inequality A
Subtract 28 from both sides
Split by 4 on both sides
Reformulate
Address inequality B
Subtract 28 from both sides
Split by 4 on both sides
consequently
The height range of the cheerleaders is the interval [58, 74)
It consists of every real number starting from 58 inches and less than 74 inches
