Which of the following triangles have three sides of different length?
A. acute
B. scalene
C.equilateral
D. right
Answer:
B. scalene
Step-by-step explanation:
A. acute - all angles are less than 90 degrees
B. scalene - all sides are different lengths
C.equilateral - all sides the same length
D. right- one angle is 90 degrees
Answer:
B
Step-by-step explanation:
Scalene Triangle A scalene triangle is a triangle in which all three sides are different lengths. Equilateral A polygon is equilateral if all of its sides are the same length

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

iki has a piece of string that she cuts into smaller pieces. This line plot shows the lengths of the pieces. Raj has a piece of string that is 12 as long as Kiki's third-longest piece. (Note: The problem says third-longest piece, not third-longest length.)
How long is Raj's piece of string?
Enter your answer as a mixed numbe
Line plot titled Pieces of String. The number line is labeled Length in inches and goes from 4 and 1 fourth to 5 and 3 fourths by fourths. Thereare 2 marks above 4 and 1 fourth, 3 marks above 4 and 1 half, 2 marks above 4 and 3 fourths, 2 marks above 5, 4 marks above 5 and 1 fourth, 1 mark above 5 and 1 half, and 2 marks above 5 and 3 fourths.

Step-by-step explanation:
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.
===========================================================
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.
find surface area of the prism pls!!!!! explain too. I really need help!!!
Answer: 104 square inches
Step-by-step explanation:
The surface area of a prism is the sum of the surface are of all of it's faces.
We can turn that into this equation SA = 2(w x l) + 2(l x h) + 2(w x h) where w is width, l is length, h is height, and 2(w x l) is the top and the bottom surface areas, 2(l x h) is the left and right sides, and 2(w x h) is the front and back.
Substitute to get this: SA = 2(6 x 2) + 2(2 x 5) + 2(6 x 5)
Simplify with multiplication to get this: SA = 24 + 20 + 60
Simplify with addition to get this: SA = 104
Add the unit label and you get 104 square inches.

6(5 - 3x) - 5(3x + 2)
Answer:
Step-by-step explanation:
I conclude that you need to find the value of x
6(5 - 3x) - 5(3x + 2)
30 - 18x -15x -10 = 0
-33x +20 = 0
33x = -20
x = -20/33

Which angles are vertical to each other ? Select all that apply.
Answer:
angles 5 and 7
angles 2 and 4
angles 12 and 10
please help it's due in a few minutes
Answer:
x + 90 = 7x
<=> 6x = 90
<=> x = 15
with x = 15 => the measure of each vertical angle is
