1. 
*0.3,0.4,0.7
0.3^{2} + 0.4^{2} =  0.7^{2}
0.09 + 0.16 = 0.49
0.25 = 0.49
<span>that is not true

2. 
*7, 9, 13
7^{2} +  9^{2} = 13^{2}
49 + 81 = 169
130 = 169

that is not true 

3. 
*10, 24, 26
10^{2}  + 24^{2} = 26^{2}&#10;
100 + 576 = 676
676 = 676

that is true so  the answer is c

What is the difference in price per kg between chicken sold at $23.24/kg and turkey sold at $5.17/250 g?
Fed [463]
There are 1000 grams in 1 KILOgram.

therefore in 23.24/kg can be just written using grams as 23.24/1000, since 1kg = 1000 g.

so the price of the chicken per gram is then 23.24/1000 or $0.02324 per gram, roughly 2 and 1/3 pennies per gram.

and the turkey is 5.17/250 in grams already, that gives us $0.02068 per gram, which is roughly 2 pennies.

well, their price difference is 0.02324 - 0.02068, which is 0.00256 per gram  unit.

since we know there are 1000 grams in 1 Kg, how much is that for 1000 grams or a Kg?   0.00256 * 1000 or $2.56.

I need the answers to 7.
Mrrafil [7]

Answer: 8 22 7 13 from top to bottom

Step-by-step explanation:

On the first row, the number of 2-player games is 1 meaning 2 players are playing meaning 48 are left to play the 6-player games so 8 is the number

On the second, the number of 6-player games is 1 meaning 6 players are playing meaning 44 are left to play the 2-player games so 22 is the number

On the third, the number of 2-player games is 4 meaning 8 players are playing meaning 42 are left to play the 6-player games so 7 is the number

On the fourth, the number of 6-player games is 4 meaning 24 players are playing meaning 26 are left to play the 2-player games so 13 is the number

Are triangles DEF and LNM similar if LN equals 5 MN equals 3 DE equals 10 and FE equals 6
melisa1 [442]

Answer:

D.  Yes by SAS Similarity Postulate

Step-by-step explanation:

This is the answer because if you flip triangle LNM around to shape the DEF.  Then you will see that:

1. angle D is congruent to angle L

2. angle E is congruent to angle N

3. angle F is congruent to angle M

4. angle E and N are both 90 degrees

Because (DE and LN) and (MN and FE) are similar and (E and N) are 90 degrees, then we do not need (FD and ML) to tell if triangle DEF and triangle LNM is similar or not. They are similar.

We next need to figure out if the triangles are similar by SSS (Side-side-side) Similarity Postulate or SAS (side-angle-side) Similarity Postulate.  The SAS Similarity Postulate states that if you have 2 similar sides and 1 congruent angle, then the two shapes are similar. Right now we have 2 similar sides in (DE and LN) and (MN and FE) and 1 congruent angle that are both 90 degrees. This follows all the rules of the SAS Similarity Postulate, so that means that these two triangles are similar by SAS Similarity Postulate.
