What is the length to the nearest tenth of the altitude of an equilateral triangle with a perimeter of 30 inches

Each side of an equilateral triangle = perimeter / 3.
Each side = 10 inches.
The altitude divides the triangle into two 30 60 90 triangles.  The hypotenuse is 10 inches and the short side is 5 inches.
altitude^2 = 10^2 - 5^2
altitude^2 = 100 - 25
altitude^2 = 75
altitude = <span> <span> <span> 8.6602540378 </span> </span> </span>

I need to submit this soon help plz, sorry for asking a lot, I'm not that good at math

Answer:

1.4000

2.5.551

3.6.8

4.10.00

5.4

Step-by-step explanation:

1 4066 as an example start from the end a 5 or more it turns to a zero and the one next to it

so in this case we now have 4100 but since it isn't 5 or more we make it a zero and move on so now we have 4000

sorry if I am wrong I am also an idiot so hopefully this helps for the future :)

Triangle XYZ is located at X (−2, 1), Y (−4, −3), and Z (0, −2). The triangle is then transformed using the rule (x−1, y+3) to f
Airida [17]
<span>You have to apply the rule to the XYZ coordinates, so X'= (-2-1, 1+3) Y'= (-4-1, -3+3) Z'= (0-1, -2+3) So the new coordinates are X' (-3, 4), Y' (-5, 0), and Z'(-1, 1) This is actually translation not transformation, as the shape doesn't change it just moves</span>

Please help find the greatest common factor for these two problems
vekshin1

A greatest common factor is the largest number that goes into two or more numbers (in this case two). To find the GCF of two numbers, we have to find the prime factorization (how to express a number as a product of prime numbers) and then see which numbers are common in both of the prime factorizations.

13. The prime factorization of 8 is 2 * 2 * 2. The prime factorization of 26 is 2 * 13. Looking at the prime factorizations, we can see that both of them have 2. That means that the GCF is 1 * 2 which is 2.

12. The prime factorization of 105 is 3 * 5 * 7. The prime factorization of -30 is -5 * 6. We see that the number shared 5. That means that the GCF is 5 * 1 or 5.
