Answer:
[tex]\$527.2[/tex]
Step-by-step explanation:
[tex]r_i[/tex] = Inner radius
Inner circumference = 4.5 m
[tex]2\pi r_i=4.5\\\Rightarrow r_i=\dfrac{4.5}{2\pi}\\\Rightarrow r_i=\dfrac{2.25}{\pi}[/tex]
[tex]r_o[/tex] = Outer radius
Outer circumference = 4.6 m
[tex]2\pi r_o=4.6\\\Rightarrow r_o=\dfrac{4.6}{2\pi}\\\Rightarrow r_o=\dfrac{2.3}{\pi}[/tex]
h = Height of cylindrical pipe = 8 m
Total surface area to be painted
[tex]s=\pi r_i^2h+\pi r_o^2h\\\Rightarrow s=\pi h(r_i^2+r_o^2)\\\Rightarrow s=\pi\times 8((\dfrac{2.25}{\pi})^2+(\dfrac{2.3}{\pi})^2)\\\Rightarrow s=26.36\ \text{m}^2[/tex]
Cost of painting 1 square meter is 20
Cost of painting the inner and outer surfaces is [tex]20\times 26.36=\$527.2[/tex]
The total cost painting the surfaces is [tex]\$527.2[/tex].

The answer is x = 7
Problem is I don’t how to get there
Answer:
x=7
Step-by-step explanation:
okay so you can see that there is a isocales triangke so that means the other base angle has to be 8x
then you know that the dioganels are perpendicular to each other
so then you know that 8x+5x-1+90=180
13x-1=90
13x=91
x=7

Regular hexagons P and Q are shown.

Q
P
How do the areas of hexagons Pand compare?
O A The area of Pis 3 times the area of Q.
OB. The area of Pis 9 times the area of 0.
OC. The area of Pis 12 times the area of Q.
OD. The area of Pis 18 times the area of Q.
9514 1404 393
Answer:
B. The area of P is 9 times the area of Q.
Step-by-step explanation:
The areas of similar figures are related by the square of the scale factor of their linear dimensions. The ratio of side lengths is ...
side of P : side of Q = 6 : 2 = 3 : 1
So, the ratio of areas is ...
area of P : area of Q = 3² : 1² = 9 : 1
The area of P is 9 times that of Q.

Her pie plate is 9 inches across. What will the area of her pie be? Use 3.14 for pi.
Answer:
63.585 sq. inches
Step-by-step explanation:
r = 9in ÷ 2
A = π (4.5)²
A = 63.585 sq. inches
Radius of pie plate is 63.58 square inches
Area of circle:Given that;
Diameter of pie plate = 9 inches
Find:
Area of pie plate
Computation:
Radius of pie plate = 9/2 inches
Radius of pie plate = 4.5 inches
Area of circle = Area of pie plate
Area of pie plate = πr²
Area of pie plate = (3.14)(4.5)²
Radius of pie plate = 63.58 square inches

The expression (3x^7)^4 is equivalent to cx^n.What is the value of c?
Answer: It’s 81
Step-by-step explanation:
I think it’s 81 because u use the distributive property (xy)^a=x^a y^a
and in the situation you change it into 3^4(x^7)^4 and u simplify 3^4 and get 81 and then just multiply 7 and 4 and your answer is 81x^28. 81 is c in the equation
We want to find an equivalent expression to (3x^7)^4 of the form cx^n, and we want to find the value of c.
The equivalent expression is:
[tex]81*x^{28}[/tex]
So the value of c is:
c = 81.
First, we need to remember two properties of exponents.
The exponents are distributive under multiplications.
And we know that:
[tex](a^n)^m = a^{n*m}[/tex]
Using these two properties, we can rewrite:
[tex](3x^7)^4 = (3^4)*(x^{7*4}) = 81*x^{28}[/tex]
So the equivalent expression is:
[tex]81*x^{28}[/tex]
Then we have c = 81.
