Answer:
Lucy sews 
dresses in 1 hour.
Step-by-step explanation:
Given:
Lucy sews 
of a dress in 
hour.
She sews at constant rate.
We need to find the number of dresses she makes in 1 hour.
In hour = dress
So in 1 hour = Number of dresses in 1 hour
By using Unitary method we get;
Number of dresses in 1 hour= 
Hence Lucy sews dresses in 1 hour.

The given ratio of the sides of the triangles is 4:10:7. Let the sides be 4x, 10x and 7x .
And given perimeter is 252 meters .
Perimeter is the sum of all sides. So we get
Dividing both sides by 21
So the sides are

Answer:
2√2
Step-by-step explanation:
compare this equation with the standard equation of a circle centered at (h, k) with radius r:
(x - h)^2 + (y - k)^2 = r^2
(x - 5)^2 + (y + 7)^2=8
Clearly, r^2 = (radius)^2 = 8, and so the radius, r, is √8, or 2√2
