Which describes all decimals that are rational numbers?
A. the decimal terminates or repeats.
B. the decimal terminates and does not repeat.
C. the decimal neither terminates nor repeats.
D. the decimal repeats and does not terminate.

Answers

Answer 1
Answer: A. the decimal terminates or repeats.

===========================================================

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.

Step-by-step explanation:

by Pythagorean theorem,

area of blue square = area of green square + area of red square

                                 = 35 + 50

Find the Area of the shape
(Area of Composite Shapes)

Answers

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

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!

Answers

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

which angles are complementary to each other ? select all that apply

Answers

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.

Hope this helps :)

Angle 1 and Angle 5 are complementary because the sum of both of those angles equals 90 degrees and the other 3 angles cannot be complementary to each other because they are already 90 degree angles by themself

What is the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2?

Answers

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

85 ft __________

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
