Answer: -54
Step-by-step explanation: 53 + 1 = 54
Answer:
Surface area of the whole figure
Step-by-step explanation:
The surface area of the figure :
Surface area of the cylinder(excluding top)+Surface area of the cone(excluding bottom)
Radius of the cylinder=3 inch and Height of cylinder=13 inch
Surface area of the cylinder with one circular face
As,
Surface area of the cone excluding base:
l= slant height=5 inch r= radius= 3 inch
Surface area of the cone =
Total surface area of the whole figure
Answer: 32
Step-by-step explanation:
There are 18 boys and 14 girls (4 more boys than girls. 32 students total.
Answer:
A) 0.05
Step-by-step explanation:
Let's summarize into an equation the information we can get from that table.
We have 4 liters of an acid of an unknown concentration, let's call it (4x).
We have 10 liters of an acid with known concentration of 0.40.
And we have a total of 14 liters overall with a concentration of 0.3o.
That's like a weighted average formula: 4x + 10 y = 14z
Let's replace the concentration values we know and solve this:
4x + 10 (0.4) = 14 * 0.3
4x + 4 = 4.2
4x = 0.2
x = 0.05
So, the concentration of the 4 liters of acid on concentration X are in fact of concentration of 0.05.
