Which arrangement shows −27/5 , −4.1 , −5 3/5 , and −3 in order from least to greatest?
A. −4.1, −27/5 , −3 , −5 3/5
B. −4.1 , −27/5 , −5 3/5 , −3
C. −5 3/5 , −27/5 , −4.1 , −3
D. −5 3/5, −3 , −4.1 , −27/5
The solution of numbers in their ascending order is Option C.
−5 3/5 , −27/5 , −4.1 , −3
What is Ascending Order?
When numbers are arranged in ascending order, they are done so from least to largest. We must first compare the numbers before we may arrange them in any order. Compare first, then order. Numbers arranged in ascending order: Determine how many digits each number has.
Given data ,
The numbers in the set S is S = { -27/5 , -4.1 , -5 3/5 , -3 }
Now , the fractions -27/5 and -5 3/5 can be simplified as
-27/5 = -5.4
-5 3/5 = -28/5
= -5.6
And , the numbers in the set S = { -5.4 , -4.1 , -5.6 , -3 }
The larger negative numbers are smaller in value
So , the numbers in their ascending form will be
-5.6 < -5.4 < -4.1 < -3
And ,
-5 3/5 < -27/5 < -4.1 < -3
Hence , the ascending form of the numbers is -5 3/5 , -27/5 , -4.1 , -3

What is venn diagram ?A Venn diagram is a diagram that uses circles to show the relationships between things or finite groups of things. Intersecting circles have one thing in common, but non-intersecting circles do not have these features.
Venn diagrams help visualize the similarities and differences between two concepts. They have long been recognized for their usefulness as educational tools. Venn diagrams have been used as part of introductory logic curricula and in elementary school planning around the world since the mid-20th century.
Venn diagrams help show how different concepts and elements intersect. At a glance, you can see how things are similar, how they differ, and where and how they overlap. The center of a Venn diagram (the intersection of two or more circles) often represents a connection or main idea that can be decomposed into various other circles, and labels on the outer part are more common than labels in the center. is clear. .

The correct alternative, based on the parallel, triangle sum, and isosceles triangle criteria, is 2.
How to spot the correct optionAlternative 1
Since the base angle of an isosceles triangle is 52 degrees, let's say the third angle is x, and according to the triangle sum property,
x + 2 * 52 = 180,
x = 76.
triangle at the base
32 + 2x = 180 (triangle sum property for isosceles triangle)
x = 74
In accordance with the triangle sum property for isosceles triangles, the figure demonstrates that the base angle of the triangle at its base is also equal to 76.
False choice: Angles 74 and 76 are not equal.
Alternative 2:
x + 2 * 76 = 180 (triangle sum property for isosceles triangle)
x = 28
The diagram demonstrates that the triangle at the base angle has angle = 28.
124 + 2x = 180 (triangle sum property for isosceles triangle)
x = 28
Since the two angles 28 and 28 are equivalent, the choice is correct.

Question B: During what interval(s) of the domain is the baseball’s height decreasing the fastest?
Options: A= 6 < x < 8; the slop is the steepest for this interval
B= 8 < x < 10; the slop is the steepest for this interval
C= 6 < x < 10; the slop is decreasing for this interval
D= 6 < x < 12; is where the slope is decreasing
Step-by-step explanation:
it decreases the fastest, where it drops the most feet in the same period of time.
the dots are made in 2 seconds intervals.
between the seconds 6 and 8 the ball drops from 65 ft to 25 ft (a drop of 65 - 25 = 40 ft).
bergen the seconds 8 and 10 the ball drops from 25 ft to 5 ft (a drop of 25 - 5 = 20 ft).
and then between the seconds 10 and 12 the ball drops from 5 ft to 0 ft (a drop of 5 ft).
so, A is the right answer. with 40 ft in 2 seconds the ball is dropping the most (= the fastest) between the seconds 6 and 8. which means the slope is negatively the steepest there = the height is decreasing the fastest.
