A dome of a building is in the form of a hemisphere from inside it was whitewashed at the cost of rupees 4989.60 if the cost of white washing is rupees 20 per meter square find the inside surface area of dome and volume of air inside the dome
Answer: [tex]249.48\ m^2; 369.168\ m^3[/tex]
Step-by-step explanation:
Given
Cost of white-washing =Rs. 4989.60
Rate =20 per meter square
So, inside area of = [tex]\dfrac{4989.60}{20}=249.48\ m^2[/tex]
The surface area of dome= [tex]4\pi\ r^2=249.48[/tex]
[tex]4\times 3.142\times r^2=249.48\\r^2=\frac{249.48}{4\times 3.142}=19.85\\r=4.455\ m[/tex]
The volume of air in the dome [tex]V=\frac{4}{3}\pi r^3[/tex]
[tex]V=\frac{4}{3}\cdot 3.142\cdot (4.45)^3\\V=369.17\ m^3[/tex]

y = x - 1
x + 4y = 16
Im having troubles. Can some 1 explain in complete explanations and all expressions.
{x,y} = {4, -3}
Substitution :
// Solve equation [2] for the variable x
[2] x = 4y + 16
// Plug this in for variable x in equation [1]
[1] (4y+16) + y = 1
[1] 5y = -15
// Solve equation [1] for the variable y
[1] 5y = - 15
[1] y = - 3
// By now we know this much :
x = 4y+16
y = -3
// Use the y value to solve for x
x = 4(-3)+16 = 4
Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. (2 points)
f of x equals eight divided by x and g of x equals eight divided by x
Answer:
we can say that f and g are inverses of each other because f(g(x)) = x and g(f(x)) = x
Step-by-step explanation:
We need to confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.
We have
[tex]f(x)= \frac{8}{x}\\g(x)=\frac{8}{x}[/tex]
Now, finding f(g(x))
Put x = 8/x in f(x)
[tex]f(g(x)) =\frac{8}{\frac{8}{x} }\\=8\div \frac{8}{x}\\=8 \times \frac{x}{8}\\=x[/tex]
So, we get f(g(x))=x
Now, find g(f(x))
Put x = 8/x in g(x)
[tex]g(f(x)) =\frac{8}{\frac{8}{x} }\\=8\div \frac{8}{x}\\=8 \times \frac{x}{8}\\=x[/tex]
So, we get g(f(x)) = x
Therefore we can say that f and g are inverses of each other because f(g(x)) = x and g(f(x)) = x

If the total cost of Lee's trip is $1,480.00 then Lee used
gallons of gas. ___________
Answer:
It will cost him $616 for 160 gallons of gas.
Step-by-step EXPLANATION FIRST YOU HAVE TO MULTIPLY 3.25 BY 160 TO GET $520, THEN JUST ADD IT BY $96 TO GET $616.
Step-by-step explanation:
You are running a concession stand at a basketball game. You are selling hotdogs and sodas. Each hot dog costs $2.30 and each soda costs $1.50. At the end of the night you made a total of $110.00. You sold a total of 60 hot dogs and sodas combined. You must report the number of hot dogs sold and the number of sodas sold X is the number of hot dogs and Y is the number of sodas.
a. Create two equations to represent the situation.
b. Solve the system of equations so you get an answer for x and y.
c. What does the solution mean?
Step-by-step explanation:
2.3X + 1.5Y = 110
X= 110/2.3 - 1.5Y/2.3.....(1)
x + y = 60
x= 60-Y......(2)
so use these two equations
60-Y = 110/2.3 - 1.5Y/2.3
60-110/2.3 = 1.5Y/2.3 + Y
280/23 = 8/23 Y
Y = 35
So now sub Y into (2)
X= 60-35
X= 25
