Answer:
Each student gets 11 pieces.
Step-by-step explanation:
80 ÷ 7 = 11.42857
80 divided by 7 comes out to a decimal therefore, you will have a remainder. 7 × 11 = 77
The answer would be 11 remainder 3.
B) 4Na + O₂ → 2Na₂O
b) H₂ + Cl₂ ---> 2HCi
Answer:
-5r + 8r +5
= (-5+8)r+5 (we can calculate number in same variabe)
= 3r +5

(8*square root of 3*π)/3
Answer: x = 14.43
Step-by-step explanation:
The Pythagorean Theorem states the following:
a^2 + b^2 = c^2
Make one side of the triangle x
Make the second side of the triangle 2x
Now, you can plug the values into the equation, right?
x^2 + 2x^2 = 25^2 or 625
3x^2 = 625
Divide each side by 3 and you are left with:
x^2 = 208.33
Now, take the square root of 208.33
x = 14.43
That is the shorter side. The longer side is twice that value: Therefore, 14.43 x 2 = 28.86 14.43 is one side of the triangle. The other is that same value times two. Therefore, the sides of your triangle are: 14.43 Shorter side 28.86 Longer side
