Step-by-step explanation:
Let's take the unit ratio of weight to length:
[tex] \frac{15 \: pounds}{4 \: feet} = 3.75 \frac{pound}{feet}[/tex]
Now that we have the unit ratio, let's multiply it to the similar pipe which is 7 feet long.
[tex]3.75 \frac{pounds}{feet} \times 7 \: feet = 26.25 \: pounds[/tex]

Thuy wrote the system of equations. 24 x + 36 y = 72. Negative 16 x + 8 y = 80. If the second equation is multiplied by 3, what should the first equation be multiplied by to eliminate the x variable by addition?
Answer:
multiply the first equation by 2
Step-by-step explanation:
24x + 36y = 72
-16x + 8y = 80
48x + 72y = 144
-48x + 24y = 240
96y = 384
y = 4
24x + 36(4) = 72
24x + 144 = 72
24x = -72
x = -3
(-3, 4)
First equation should be multiplied by 2 to eliminate the x variable by addition.
What is the system of equation?
" A system of equation is a finite set of equations for which we find the common solution."
According to the question,
System of equations are
24x + 36y = 72
-16x + 8y = 80
As per the given condition,
Second equation multiply by 3 we get,
-48x + 24y =240
To eliminate x by adding we have to multiply first equation by 2 we get,
48x + 72y = 144
Now add both the equation we get,
96y =384
⇒ y = 4
Hence, first equation should be multiplied by 2 to eliminate the x variable by addition.

Deon is playing fetch with his dog with a toy that is shaped like a circle. The circumference of the toy is 12π inches.
Which measurement is closest to the area of the toy in square inches?
18.84 in.²
37.68 in.²
113.04 in.²
452.16 in.²
Answer:
113.04
Step-by-step explanation:
The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex]
Given that,
Deon is playing fetch with his dog with a toy that is shaped like a circle,
The circumference of the sculpture is 12π inches.
We have to determine,
Which measurement is closest to the area of the toy in square inches.
According to the question,
Circumference of the circle = [tex]2\pi r[/tex]
Where, circumference = [tex]12\pi[/tex]
Then,
[tex]12\pi =2\pi r \\\\r = \dfrac{12\pi }{2\pi }\\\\r = 6\ inches[/tex]
Therefore,
Deon is playing fetch with his dog with a toy that is shaped like a circle.
Area of the circle = [tex]\pi r^{2}[/tex]
Where, r = 6inches
Then,
Area of the circle is given by,
[tex]= \pi r ^{2}\\\\= 3.14 \times (6)^{2}\\\\= 3.14 \times 36\\\\= 113.04\ inches^{2}[/tex]
Hence, The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex].

15. Challenge! Find the surface area of the figure below.
The surface area of the figure with a diameter of 6cm and height of 25cm is 84π square cm
The total surface area of a cylinderThe formula for calculating the TSA of a cylinder is expressed as:
S = 2πr(r+h)
Since the figure is half of a cylinder, hence;
S = πr(r+h)
Given the following
r = 6/2 = 3cm
h = 25cm
Substitute
S = π(3)(3+25)
S = 84π square cm
Hence the surface area of the figure below is 84π square cm
