find a ratio equivalent to the ratio 9/21

Answer:

Step-by-step explanation:

Ok, so pretend each k has a 1 in front of it. so 1k+1k+1k= 3k. If you need a different equation, you can do 2k+1k=3k or something like that. :)

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.

" 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.

Answer:

96/100

Step-by-step explanation:

Numerator & Denominator for 0.96 as a Fraction

0.96 = 0 96/100

numerator/denominator = 96/100

Level of Precision for 0.96 = 0 96/100

Customize the level of precision to break 0.96 down further into a fraction. Note that the last digit after the precision point is rounded up or down accordingly.

With that in mind decimal 0.96 with a precision point of two has the following fractional breakdown:

96/100

= 48/50

= 24/25

Step-by-step explanation:

its 25 inches

The surface area of the figure with a diameter of 6cm and height of 25cm is 84π square cm

The 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

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].
