Explanation:
A terminating decimal example would be something like 0.2 which converts to the rational number, aka fraction, 1/5. The word "terminate" means "stop", so it's any decimal that doesn't go on forever.
A repeating decimal is something like 0.33333 where the 3s go on forever, and that converts to 1/3.
If any of these conditions happen, then the number is rational.
--------
For something like pi = 3.14159... where there isn't a pattern and it goes on forever, then we consider this number irrational. The term "irrational" literally means "not rational". So this allows us to rule out choice C.
Choices B and D are partially true, but they only paint half the picture needed to form all rational numbers. Choice A is the most complete statement.
In other words, while choice B is technically true, it leaves out repeating decimals. Choice D is the same way but it leaves out terminating decimals. So we can rule out choices B and D.

Answer:
b = 42° and c = 180-42 = 138°
Answer:
b) 42°
c) 138°
Step-by-step explanation:
Get 42° by looking at its vertical partner(vertical angle). Get 138° by subtracting 42 from it. Subtract 42 from the sum of the entire angle, and get 180° degrees.

A: -a/-b=c (negative number divided by negative number is positive number A is correct)
B: -a x b =c (negative number times positive number is become a negative number so correct answer is -c B is wrong)
C: -a/b=c (negative number divided by positive number is become a negative number so correct answer is -c C is wrong)
D: -a x -b=-c (negative number times negative number is become a positive number so correct answer is c D is also wrong)

A square pyramid. The square base has side lengths of 5 feet. The 4 triangular sides have a base of 5 feet and height of 6 feet.
What is the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2?
Answer:
85 ft^2
Step-by-step explanation:
Ok, the square base area is 5 x 5 = 25 square feet
the triangular sides have an area of (1/2)(5)(6) each, which is 15 square feet each, like you said.
To find the total surface area, you multiply the 15 square feet x 4 (there are 4 sides) and add the base.
15 x 4 = 60 + 25 = 85 square feet

Answer:
A
Step-by-step explanation:
V = (0.04)*H (Company P)
V = (0.06)*H (Company S)
V represents the vacation hours and H is the hours worked
If they both work 2080 hours
V1 = (0.04)*(2080) = 83.2 vacation hours (Company P)
V2 = (0.06)*(2080) = 124.8 vacation hours (Company S)
124.8 - 83.2 = 41.6 hrs

Which of the following are needed to make an expression?
A. variable(s)
B. number(s)
C. equal sign
D. operation(s)
Answer:
variables is the correct answer
Answer:
ALL OF THE ABOVE
Step-by-step explanation:
An expression is a syntactic construct. It must be well-formed: the allowed operators must have the correct number of inputs in the correct places, the characters that make up these inputs must be valid, have a clear order of operations, etc.
It can be all of the above too. because everything is needed to make an expression.

which angles are complementary to each other ? select all that apply
Answer: ∠1 and ∠5
Step-by-step explanation:
You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.

How do I solve this?
Answer:
We know the width maybe 22ft and at its widest.
IF we say 3 triangles can be fit into a polygon given 2 sides then we 180 x 3 = 560 degree if its 3 rectangles then if it is easier to make 4 rectangles if square shape we can subtract the smaller measures of the missing rectangle.
With triangles;
The number of triangles is always 2 less than that that of its sides.
= 3 triangles + 2 = 5 sides.
The sum of interior angles
(n-2) x 180 = 540 degree
5-2 x 180
To determine the amount of sides; we remember
(n-2) 180
360 = (n-2) 180
+360 = 180 -360 +180
+360 = 180 = (3 triangles with 180)
900/180 = 5 sides.
If we say 5 triangles created with 3 given lengths
then same rule applies n-2 (180)
=7 sides
= if regular shape largest line 22 x 7 = 154 ft sq = Area.
Answer:
374
Step-by-step explanation:
First do the area of the triangle 7 x 22 = 308 308/2 = 154 22 x 10 = 220 220+154 =374
Find the Area of the shape
(Area of Composite Shapes)
Answer:
223.5 Km
Step-by-step explanation:
Area = Length x Width
Solving for Square Shape
8 · 6 = 48 km
Area = Length x Width
Solving for Rectangle Shape
9 · 14 = 126 km
Area = Length x Width ÷ 2
Solving for Triangle Shape
11 · 9 = 99 ÷ 2 = 49.5 Km
48 + 126 + 49.5 = 223.5 Km

Hope it is helpful...There are many cones with a height of 12 inches. Let r represent the radius and V
represent the volume of these cones.
Plot points that show the volume when r=1, r=2, r=3, and .r=4.
HELP!
Answer:
If R = 1, ~12.57 is the y. (r is the x.)
If R = 2, ~50.27
If r = 3, ~113.1
If r = 4, ~201.06
Step-by-step explanation:
The formula of a cone is pi * r^2 * h/3
If r = 1, we have pi * 1^2 * 12/3
12/3 = 4
and 1^2 = 1
pi * 1 * 4
4 * pi = ~12.57
if r = 2, we have an imrpoved formula,
pi*2^2 * 4 (h/3 became 4 since 12/3 = 4)
2^2 = 4
4*4 = 16
pi * 16 = ~50.27
If r = 3
our formula is pi*3^2*4
3^2 = 9
pi*9*4
9*4 = 36
36* pi = ~113.1
If r = 4,
our formula is
pi*4^2*4
4^2 = 16 and 16*4 = 64
pi*64 = ~201.06.
Answer:
If R = 1, ~12.57 is the y. (r is the x.)
If R = 2, ~50.27
If r = 3, ~113.1
If r = 4, ~201.06
