Answer:
Infinite
Step-by-step explanation:
2(x-6)+2x=4(x-3) would turn into:
2x-12+2x=4x-12 which would turn into:
4x-12=4x-12 then you could keep going if you wanted:
add 12 to both sides and subtract 4x from both sides:
0=0 (and zero does equal zero so it is unlimited solutions)
Answer:
The concentration of HCl in the mixture is 1L of 50% HCl
Step-by-step explanation:
Here, we want to know the percentage of HCl present which refers to the its concentration.
Firstly, the total volume we have is 0.375 + 0.625 = 1 L
we can calculate the percentage as follows;
The percentage of the 25% present is 37.5%
while the percentage of the 75% present is 62.5%
When we say the percentage present, we are referring to the amounts of the total liters which is 1 present.
So the concentration of the final mixture will be;
(37.5% of 25) + (62.5% of 65)
= 9.375% + 40.625%
Adding both gives = 50%
So the concentration we have is 1L of 50% HCl
Answer:
The diagonal = 8.8 units to the nearest tenth
Step-by-step explanation:
∵ L = 7 units
∵ W = 5 units
∴ Diagonal = ![\sqrt{(7)^{2}+(5)^{2}}=\sqrt{49+25}=\sqrt{74}](https://tex.z-dn.net/?f=%5Csqrt%7B%287%29%5E%7B2%7D%2B%285%29%5E%7B2%7D%7D%3D%5Csqrt%7B49%2B25%7D%3D%5Csqrt%7B74%7D)
∵
= 8.802325
∴ The diagonal = 8.8 units to the nearest tenth
