Answer:

The circumference of Mario's circle is 75 cm

Step-by-step explanation:

<u><em>The correct question is</em></u>

Joe drew a circle whose circumference is 25 cm. Mario drew a circle whose diameter is 3 times the diameter or Joe’s circle. What is the circumference of Mario’s circle?

we know that

All circles are similar

The ratio of the circumferences of two circles, is equal to the scale factor

Let

z ----> the scale factor

x ----> circumference of Mario's circle

y-----> circumference of Joe's circle

so

z=\frac{x}{y}

we have

z=3\\y=25\ cm

substitute the given values

3=\frac{x}{25}

solve for x

x=3(25)=75\ cm

therefore

The circumference of Mario's circle is 75 cm

Evaluate x4 + 4x3 - 2x2 + 11x - 6 for x = 3
erica [24]

Step-by-step explanation:

f(x)  =  {x}^{4}  + 4 {x}^{3}  - 2 {x}^{2}  + 11x - 6

f(3) =  {3}^{4}  + 4. {3}^{3}  - 2. {3}^{2}  + 11.3 - 6

f(3) = 81 + 4.27 - 2.9 + 33 - 6

f(3) = 81 + 108 - 18 + 33 - 6

f(3) = 198

I'm don't understand polygons, as you should know
lawyer [7]

Answer:

540°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5, thus

sum = 180° × 3 = 540°

PLEASE HELP! A positive number is 1/3 of another number. The sum of the numbers is five less than the square of the larger numbe
antoniya [11.8K]

Answer: The numbers are 1 and 3.

Step-by-step explanation:

Let x = smaller number , y= larger number.

As per given,

x=\dfrac{y}{3}   ...(i)

x+y=y^2-5       ...(ii)

Put value of x from (i) in (ii)

\dfrac{y}{3}+y=y^2-5\\\\\Rightarrow\ \dfrac43y=y^2-5\\\\\Rightarrow\ 3y^2-4y-15=0\\\\\Rightarrow\ 3y^2-9y+5y-15=0\\\\\Rightarrow\ 3y(y-3)+5(y-3)=0\\\\\Rightarrow\ (y-3)(3y+5)=0\\\\\Rightarrow\ y=3 \ \ or\ y=\dfrac{-5}{3}

Since numbers are positive , so y=3 is correct.

And x will be 1  [from (i)]

Hence, the numbers are 1 and 3.
