Answer:
The answer is 743.4 square inches
Step-by-step explanation:
1. find the length- 2 x 40=80 cm
2. find the width- 1.5 x 40= 60cm
3. find area (Length x width)- 80 x 60= 4800 square cm
4. find length but in inches- 1in=2.54cm length=80/2.54 = 31.5 inches
5. find width but in inches- width= 60/2.54= 23.6 inches
6. Find area(length x width)- 31.5 x 23.6= 743.4 square inches
Answer: 92.50%
From the given problem, we can say that the total volume of the concentration is:
The initial volume of the solution is 555 mL. After the evaporation, the 50% sucrose solution lost 255 mL.
To find the concentration of the remaining 300 mL, we will use the following formula:
Where:
C₁ = initial concentration
C₂ = final concentration
V₁ = initial volume
V₂ = final volume
From the given, we know that:
C₁ = 50% = 0.50
C₂ = ?
V₁ = 555 mL
V₂ = 300 mL
Substitute these to the formula and we will get:
Therefore, we can say that the sucrose concentration in the remaining 300mL is 92.50%
So what is the question i didnt get it?
Answer:
axm
Step-by-step explanation:
For number 7:
a) The sum of the adjacent angles is 180. Because if its any three angles thats half of the angles all together 3/6 = 180/360.
b) The sum of the angles in the center is 360 degrees. Because 60 x 6 = 360.
c) The unknown angles (center angles) are 61.25 degrees.
For number 8 (bonus):
It's C) 90 Degrees, because it's a right angle.
Hope this helps :)
