Answer:
48 yards
Step-by-step explanation:
To calculate the perimeter you have to add the outline of the triangle together.
16 + 16 + 16 = 48
You can also do 16 × 3 = 48
So, your answer is 48 yards.
Have a great day! :)
this is area right???
Answer:
Yes
Step-by-step explanation:
So permiter is two*lengths plus 2*width of a shape.
Area is the length times the width.
For examplel if a square has a length of 2, and a width of 3 the permiteter is:
2*2+3*3=
4+9
=
13
On the other hand, area would be:
2*3
=
6

A room is thrice as long as the breadth. It contains 270m^3 of air and the cost of painting its four walls at Rs 15 per m^2 is Rs. 3600, find the cost of carpeting the floor at Rs. 98 per m^2.
Answer: ₹2646
Step-by-step explanation:
Given
The volume of the room is [tex]V=270\ m^3[/tex]
cost of painting the walls is ₹[tex]3600[/tex] at the rate of [tex]15\ m^2[/tex]
So, the area of walls is
[tex]\Rightarrow A=\dfrac{3600}{15}\\\\\Rightarrow A=240\ m^2[/tex]
This the area of 4 walls i.e.
[tex]\Rightarrow 240=2[hl+hb]\\\Rightarrow 120=h[l+b]\\\Rightarrow 120=4bh\quad [\text{length is thrice of width}]\\\Rightarrow 30=bh\qua \ldots(i)[/tex]
The volume of the room is given by
[tex]V=l\times b\times h\\270=3b\times b\times h\\90=hb^2\quad \ldots(ii)[/tex]
Divide (i) and (ii)
[tex]\Rightarrow \dfrac{90}{30}=\dfrac{b^2h}{bh}\\\\\Rightarrow b=3\ m[/tex]
So, the length of the room is
[tex]l=3b\\l=3\times 3\\l=9\ m[/tex]
The area of the floor is
[tex]\Rightarrow A_o=l\times b\\\Rightarrow A_o=9\times 3\\\Rightarrow A_o=27\ m^2[/tex]
The cost of flooring is
[tex]\Rightarrow 27\times 98\\\Rightarrow Rs.2646[/tex]

=2*2(12+5)
=4*17
=68 cm^2
Answer:
188 cm²
Step-by-step explanation:
TSA of cuboid = 2(lb + bh + hl)
= 2 {(12*2) + (2*5) + (5*12)}
= 2 (24 + 10 + 60)
= 2 (94)

Use the table to describe the locations of the zeros of the quadratic function $f$ .
The zeros are between _ and_ , and between_ and_ .
Answer:
The zeros are between -4 and -3, and between 0 and 1
Step-by-step explanation:
Here, we want to location of the zeros
As we can know, at the zeros of a quadratic function, the y value at those point is zero
So whenever we have y value being zero, we have it that the x value at that point is a zero or root of the quadratic function
Now, looking at the table, we can see that between the point x = -4 and -3; y moved from -2 to 2
For this movement to occur, we must have passed through 0 as we have -1 ,0 and 1 between the numbers as -2 and 2
So obviously, the root is between -4 and -3
Secondly as we can see, f(x) moved from 2 to -2
The numbers between here are 1 , 0 and -1
So definitely the root lies between the x values of 0 and 1

What is the volume of a right circular cone that has a height of 19 feet in a base with a diameter of 18.7 feet round your answer to the nearest 10th of a cubic foot
Answer:
A = 1739.4 cubic feet
Step-by-step explanation:
B = area of base (πr²)
h = height
A = Bh/3
A = [(18.7÷2)²π × 19] / 3
A = (9.35²π×19) / 3
A = 1739.4

What is Equation of line?
The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The graph is shown in figure.
Two points on the graph are (2, 6) nd (3, 9).
Now,
Solve for the correct rule of the graph as;
Since, The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
So, We find the slope of the line as;
Two points on the graph are (2, 6) and (3, 9).
Hence,
m = (9 - 6) / (3 - 2)
m = 3/1
m = 3
Thus, The equation of line in point-slope form passing through the points (2, 6) and (3, 9).with slope 3 is defined as;
⇒ y - y₁ = m (x - x₁)
⇒ y - 6 = 3 (x - 2)
⇒ y - 6 = 3x - 6
⇒ y = 3x
Thus, The correct rule for the graph shown will be;
⇒ y = 3x

Complete the square to find the vertex of this parabola. x2-16y-4x-12=0
Answer:
Step-by-step explanation:
x^2-16y-4x-12=0
Transpose and separate x and y
16y = x^2-4x-12
16y = (x^2-4x+4) -16
16y = (x-2)^2 -16
y = (1/16)(x-2)^2 -1
This means that the vertex is at
(x-2)=0 or x=2
y = -1
=> vertex (2,-1)

Last week, Ann bought 9 books and 5 movies for a total of $124.
Today, Ann bought 4 books and 21 movies for a total of $318.
Assuming neither item has changed in price, what is the cost of a book in dollars?
Answer:
$6
Step-by-step explanation:
Set up a system of equations where b is the cost of a book and m is the cost of a movie:
9b + 5m = 124
4b + 21m = 318
Solve by elimination by multiplying the top equation by -21 and the bottom equation by 5:
-189b - 105m = -2604
20b + 105m = 1590
Add the equations together, then solve for b:
-169b = -1014
b = 6
So, the cost of a book is $6
