Answer:
3 hours
Step-by-step explanation:
D=4H+35
47=4H+35
47-35=4H
12=4H
H=3
We know that
the equation of a circle is
(x-h+(y-k)²=r²
where (k,k)----> is the center
and
r----> is the radius
y²+2x+x²-24y= -120
Group
terms that contain the same variable
(y²-24y)+(x²+2x)=-120
Complete
the square twice. Remember to balance the equation by adding the same constants
to each side
(y²-24y+144)+(x²+2x+1)=-120+144+1
<span>Rewrite as perfect squares</span>
(y-12)²+(x+1)²=25
(x+1)²+(y-12)²=5²
the answer isthe coordinates of the center are (-1,12)the radius is 5 units
Answer:
42.5 feet long.
Step-by-step explanation:
Assuming the shape of the garden is a sqaure, than
170/4=42.5 feet long.
30 = 60% of x
x being our variable, we need to figure out what x equals. Use the formula I put in the attachment. Multiply 30 by 60, and then divide the product by 100. That will give you the answer :)
6(173.04) + 3.15 + 3(29) =
1038.24 + 3.15 + 87. = 1128.39
