Can somebodyi dont understand at all and i needyou if you can ! karen has a large pile of colored rods. each color is a different length. she is trying to connect different colored rods to make triangles as part of a hanging sculpture. here is a list of rod lengths. red: 3 inches orange: 4 inches yellow: 5 inches green: 7 inches blue: 9 inches purple: 12 inches 1. how many triangles can she make with them if each side is a different color? list the combinations that work. 2. karen was just trying different combinations of colored rods one at a time, placing the colored rods together to see if they make a triangle. what method did you use to determine the triangle options? which method do you think is better and why?

I can give you a link  https://youtu.be/aUy-_WnEV30 . I hope this answers your problem, and gives you greater insight. Sorry I couldn't do more :(

$50 divided by 2 = $25 therefore
A. $75
B. 27
C. Yes

Create an expression that has a value of _1_, using only four 4s and any of the following: + , – , • , ÷, exponents, and/or parentheses?

4 * 4 / (4 * 4) = 1

I know this is a bit late but if anyone still needs help with the first question the combinations are ROY, RYG, RGB, OYG, OGB, OBP, YGB, YBP, and GBP.

Perfect tense is saying a circumstance occurred earlier in the present with a helping word. For instance number one would be have not telephoned. Adding the have indicates that it's present and the -ed indicates that it's perfect. Like number two would be have been.

Volume of a cone = PI x r^2 x h/3

Volume = PI x 5^2 x 9/3

Volume = 235.62 cubic cm.

Volume of a block of wax = L x W x H

Volume = 2 x 4 x 3 = 24 cubic cm.

Total number of blocks = Volume of cone / volume of blocks:

235.62 / 24 = 9.82

Round up to 10.

They will need 10 blocks.

A. $75 because 50÷2 is 25 so 50+25
b. 27 because 675÷25 is 27
c. yes because 25 x 17 is 425

Alright,

So LCM stands for "least common multiple"
While GCF is "greatest common factor"

Let's look at your number 1 (3&6)

3,6,9,12
6,12,18,24

Both times table has 6 in them making 6 the LCM

To find the GCF we need to know what can go into 3 equally. Since 3 is prime the greatest factor for 3 is3. 6 goes into 3 two times so 3 is the GCF.

LCM:6
GCF:3

Lets do number 10 (40&4)

For LCM you see whats the smallest number that is in both times tables

4,8,12,16,20,24,2840
40,80, 160

40 is the LCM because 40 is what's the smallest number between the two

GCF?

4 times 1 equals 4. Nothing bigger than 4 can make 4 (if your multiplying). That makes 4 automatically the GCF. :)

Find the area of the 12 right triangles using A = 1/2bh, and then find the area of the hexagon using the formula 3/2(a^2), in which a is referring to one of the sides.

I know this question it 8 over 3 and 2
