Answer:
(x-4)*2 + (y-2)*2 = 25
Step-by-step explanation:
(x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.
h = 4
k = 2
r = 5
sub in all this info:
(x-4)*2 + (y-2)*2 = 25
Answer:
x= 2/7
Step-by-step explanation:
Divide each term by 3 and then you can simplify it.
Hope this helps.
When ever I encounter problem like this, I make the equation become:
z = anything buy z.
First, you want to get 2/5 to the other side, to do so, you need to multiply 5/2 on both side. then you are left with z+1=5/2 y. Then you subtract 1 from both sides to make z on its own. The answer should be z = 3/2y or z= 1
y
2/5(z+1)=y
2/5(z+1)5/2=5/2y
z+1=5/2y
z+1-1=5/2y-1
z=3/2y or z=<span>1
y</span>
Answer:
11.362 sq km
1136.2 hectares
Step-by-step explanation:
Given that:
The farm is in the shape of a rectangle.
Dimensions of the rectangular shaped land = 2.6 km by 4.37 km
To find:
Area of land bought in square km and in hectares.
Solution:
First of all, let us have a look at the formula for area of a rectangular shape figure.
Here,
Length = 2.6 km
Width = 4.37 km
So, Area =
To convert square kilometers to hectares, we can use the following conversion formula:
1 sq km = 100 hectares
11.362 km = 100 11.362 = <em>1136.2 hectares</em>
Answer:
A) 27 degrees
Step-by-step explanation:
Arc length = fraction of the circle * circumference
Arc length = fraction of the circle * 2 * pi *r
3/4 pi = fraction of the circle * 2 * pi *5
3/4 pi = fraction of the circle *10 pi
Divide each side by 10pi
3/4 pi
-------- = fraction of a circle
10 pi
3/40 = fraction of a circle
A circle is 360 degrees
3/40 = x/360
Multiply by 360
3/40 *360 = x
27 = x
