The equation of the circle is always:
$(x - h)^{2} + (y-k)^{2} = r^{2}$
Where (h, k) is the center of the circle, r is the radius. So, the equation will be:
$x^{2} + y^{2} = 64$
Hope this helps! The answer is B.

Rename 3/10 and 2/3 using the least common denominator.

Charra [1.4K]

Answer:

LCD = 30

3/10 = 9/30

2/3 = 20/30

Step-by-step explanation:

This is the answer because:

1) First, the least common denominator is 30 because 10 x 3 is 30 and 3 x 10 is 30

2) Next, multiply the numerators with the same number you multiplied with the denominator

3 x 3 = 9

2 x 10 = 20

3) Therefore, the answers are:

3/10 = 9/30

2/3 = 20/30

Hope this helps!

The length of the base of a triangle is twice its height. if the area of the triangle is 225 square kilometers, find the height

Anon25 [30]

Let
x----------> length of the base
y----------> height

we know that
[the area of triangle]=[length of the base]*[height]/2
x=2y
A=225 km²
225=x*y/2---------> 225=(2y)*y/2-----> y²=225--------> y=15 km
x=2y--------> x=2*15------> x=30 km

the answer is
the height is 15 km
