Answer:

x^2 + y^2 = 100

Step-by-step explanation:

The general form of the equation of a circle is

(x-h)^2+(y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x-0)^2+ (y-0)^2 = 10^2

x^2 + y^2 = 100

What is the enlargement ratio if you enlarge the figure to have a width of 16 units and length of 12 units
Fantom [35]

Answer:

The enlargement ratio is 3:4

Step-by-step explanation:

We are given

a width of 16 units and length of 12 units

so,

W=16

and

L=12

now, we can find enlargement ratio

we can use formula

enlargement ratio = (length)/(width)

=\frac{L}{W}

now, we can plug values

=\frac{12}{16}

now, we can simplify it

=\frac{3}{4}

So,

The enlargement ratio is 3:4

A farmer buys a tractor for rs.70000 and after using it for some time, he sells it at a loss of 5% to another farmer. He also se
Vedmedyk [2.9K]
  • Total loss %=10+5=15%

  • CP=70000
  • loss%=15%

Now

Loss:-

\\ \sf\longmapsto 15\%\:of\:70000

\\ \sf\longmapsto \dfrac{15}{100}(70000)

\\ \sf\longmapsto 10500

Again

\\ \sf\longmapsto SP=CP-Loss

\\ \sf\longmapsto SP=70000-10500

\\ \sf\longmapsto SP=59500

Third farmer will pay 59500
