Answer: The dimensions are that 2 sides are 5 inches and two are 10 inches.
Step-by-step explanation:
The are is 50 so the dimensions should equal 50 when you do height times width. So 5*10=50 and 5+5+10+10=30
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:
huushshsusjvevshshd
Step-by-step explanation:
q=135 s and p= 45
49-x^2 factors to (7+x)(7-x). This is because both terms are perfect squares.
When you divide out 7+x because a rectangle's area equals length times width, you get 7-x
Final answer: 7-x
