Answer:

It's called Dilation when a triangle is the similar but only smaller, but as he said above, multiply the numbers by 2, you can't if they aren't numbers but if you do then it'll be the same size.

Answer:

yes the blue one is bigger but the green one is just smaller but if you multiply the sides by two it would be the same size so yeah they are similar

A sum of Rs. 1800 borrowed for 2 years at the rate of 12 % per annum. Find<br> the interest?

wel

Answer:

Step-by-step explanation:

principal (P)=1800

time(T)=2yrs

rate(R)=2%

SI=?

now,

SI=PTR÷100

= 1800×2×2÷100

=7200÷100

=72

so interest is 72.

hope this will help you :D

Brody’s town is building a pool based on a scale drawing that is 20 centimeters by 10 cemtimeters and uses the scale 1 cemtimete

Juliette [100K]

Answer:

Area of the pool is 1250 square meters.

Step-by-step explanation:

Given:

1 cm on scale is 250 cm in actual.

Therefore, 20 cm on scale is $20\times 250 = 5000\textrm{ cm}$

10 cm on scale is $10\times 250 = 2500\textrm{ cm}$

Also, we know that, $1\textrm{ cm}= \frac{1}{100}\textrm{ m}$

Therefore,

$5000\textrm{ cm}=5000\times \frac{1}{100}=50\textrm{ m}\\2500\textrm{ cm}=2500\times \frac{1}{100}=25\textrm{ m}$

Area of the pool is given as,

$Area=50\times 25=1250\textrm{ }m^{2}$

Therefore, the area of the pool is 1250 square meters.

This is so important please help

Shtirlitz [24]

Given:

The center of the circle = (-1,0)

Point on the circle = (2,-4).

To find:

The equation of the circle.

Solution:

Distance between two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between the center (-1,0) and the point on the circle (2,-4) is the radius of the circle.

$r=\sqrt{(2-(-1))^2+(-4-0)^2}$

$r=\sqrt{(2+1)^2+(-4)^2}$

$r=\sqrt{(3)^2+(-4)^2}$

On further simplification, we get

$r=\sqrt{9+16}$

$r=\sqrt{25}$

$r=5$

Now, the equation of the circle is

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

Where, (h,k) is the center and r is the radius of the circle.

The radius of the circle is 5 and the center is at (-1,0), so the equation of the circle is

$(x-(-1))^2+(y-0)^2=5^2$

$(x+1)^2+y^2=25$

Therefore, the first option is correct, i.e., $(x+1)^2+y^2=25$ .
