Answer:
The circumference of a circle is not the same as the area of the circle because the circumference represents the distance around the circle while the area represents the amount of space within the circle. Hope this helps.
Taking the 3 solutions as 3 different terms, we can create an equation as follows:
Solution 1 : 10mL with 20% acid
Solution 2 : 30mL with x% acid
Solution 3 : 40mL with 32% acid
Since solution 1 + solution 2 = solution 3, let us substitute the given values we have:
10(0.2) + 30(x) = 40(0.32)
2 + 30x = 12.8
To solve for the unknown concentration x, we subtract 2 from both sides:
2 + 30x - 2 = 12.8 - 2
30x = 10.8
Dividing both sides by 30:
30x/30 = 10.8/30
x = 0.36
Therefore the unknown solution is 36% acid.
Answer:
6.67meters
Step-by-step explanation:
The formula for the volume of a rectangular pyramid = Length × Width × Height
From the question
Volume = 200m³
Base of the pyramid = Length × Width = 6m by 5m = 6m × 5m
To find the height of the pyramid = Volume/Length × Width
Height = 200m³/ 6m × 5m
Height = 6.67m
Height of the rectangular pyramid in meters = 6.67 m
Answer:
39375
Step-by-step explanation:
All you have to do is just multiply the length x width x height.
A=3.14(pi)r(r+h2+r2) Hope this helps!
