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 :(
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.
b. 27 because 675÷25 is 27
c. yes because 25 x 17 is 425
So LCM stands for "least common multiple"
While GCF is "greatest common factor"
Let's look at your number 1 (3&6)
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.
Lets do number 10 (40&4)
For LCM you see whats the smallest number that is in both times tables
40 is the LCM because 40 is what's the smallest number between the two
4 times 1 equals 4. Nothing bigger than 4 can make 4 (if your multiplying). That makes 4 automatically the GCF. :)
