This is a triangular pyramid and has 4 faces.
Answer:
5
Step-by-step explanation:
Faces is essentially the number of sides. In an easier shape like this you could just count the number of sides. You would have 5 faces in this shape.
On a side note, when dealing with convex polyhedrons(you might not have gotten into this) you can find the number of edges by by adding the number of vertices, plus the number of vertices, minus 2.
For example, lets take a cube. The cube has 6 faces and 8 vertices. 6 + 8 - 2 = 12 edges

Find the TWO integers whos product is -12 and whose sum is 1
Answers
Answer:
[tex] \rm Numbers = 4 \ and \ -3.[/tex]
Step-by-step explanation:
Given :-
The sum of two numbers is 1 .The product of the nos . is 12 .And we need to find out the numbers. So let us take ,
First number be x Second number be 1-x .According to first condition :-
[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]
Hence the numbers are 4 and -3
Step-by-step explanation:
[tex]integers \: = x \: and \: y \\ then \: x \times y = - 12 ....(1)\\ x + y = 1.....(2) \\ x = 1 - y.....(3) \\ put \: (3 )\: in \: (1) \\ then \: (1 - y) \times y = - 12 \\ y - {y}^{2} + 12 = 0 \\ {y}^{2} - y - 12 = 0 \\ factorise \\ {y}^{2} - 4y + 3y - 12 = 0 \\ y( y - 4) + 3(y - 4) \\ (y - 4)(y + 3) \\ y = 4 \: and \: - 3 \\ thank \: you[/tex]

Answer:
V = 1716.795 cm³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius and h the height )
d = [tex]\frac{1}{3}[/tex] h = [tex]\frac{1}{3}[/tex] × 27 = 9 , then r = 9 ÷ 2 = 4.5 , so
V = 3.14 × 4.5² × 27
= 3.14 × 20.25 × 27
= 1716.795 cm³

From what I learned, take this example from a pair of dice: If you want to know the probability of getting 3, you take the event (the 3 or the thing you want to know) and divided it by the outcome (or total)
in other words : probility = event(3)/outcome(6)

Ella conducted a survey to find out the amount of time high schoolers spend surfing the Internet. From the data collected, the range of time spent was 1 hour. What does this range say about the data?
- All the students surveyed spend exactly 1 hour surfing the Internet.
- All the students surveyed spend an average of 1 hour surfing the Internet.
- The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour.
- The quotient between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour.
WHOEVER KEEPS FALSELY REPORTING MY QUESTIONS AND BLEEDING ME DRY OF POINTS, STOP. YOURE NOT FUNNY
Answers
Answer:
the answer is C
Step-by-step explanation:
The answer is C.
Because we do not have any tables graphs etc., we can only use the fact that the range is 1
The definition of range is the difference between the largest amount and the smallest amount. In equation form, it should look like this:
Now lets move to the answer choices:
Answer A. is wrong
If everyone surfed for exactly an hour, the largest amount of time would be 1 hour and the smallest amount of time would also be 1 hour. Put this into the equation and the range would be 0 which is contradicted from the data present
Answer B. is wrong because the range is not the average, the mean is the average. We are looking for the range, not the mean so Answer B. is incorrect.
Answer C. is correct. The range is the difference between the largest and the smallest. In this answer, it tells us that the range is the difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour. This follows the term of "Range" and therefore, Answer C. is correct.
Answer D. is incorrect because the range does not have anything to do with quotients.(By the way, a quotient is the result of dividing a dividend with a divisor.) The range is only obtainable with subtraction, not division, so answer D. is incorrect.
