Answer:
Perpendicular(p)=21
base(b)=20
hypotenuse(h)=29
Step-by-step explanation:
Now by using the formula:
cos A=b/h
i.e 20 by 29
1. You have that the circle that defines the part of the planter wall which gets watered by the sprinkler is: (x−10)²+(y+12)²<span>=36.
2. The standard form for the equation of a circle is:
(x-h)</span>²+(y-k)²=r²
(h,k) is the center point.
r is the radius.
3. Keeping this on mind, you can find the value of the radius, as below:
r²=36
r=√36
r=6 m
4. Then, the diameter of the circle is:
D=2r
D=2(6m)
D=12 m
<span>
What is the diameter, in meters, of the circular area that gets watered by the sprinkler?</span>
The answer is: 12 m
x²/2 =271 represents the situation where taking length twice as breadth and area as 271 ft² .
Area of a figure is the amount of space acquired by the figure
Area of a rectangle=Length x breadth
length=x
breadth=x/2
Area of rectangular lawn=lxb
=x.x/2
But as per question,
Area=271 ft²
⇒x²/2=271 1
⇒x=23.28 ft²
Therefore, x²/2 =271 represents the situation where taking length twice as breadth and area as 271 ft² .Value of x i.e. length is 23.28 ft²

Answer:
The answer is "150 seconds".
Step-by-step explanation:
Answer:
The average price of a house last year was = $124,423.96
Step-by-step explanation:
Let the average price of houses in Tennessee last year in dollars be = 
This year the increase percentage in average price was = 8.5%
The change in average price can be calculated in dollars as:
⇒ 
⇒ 
⇒ 
New increased average price in dollars can be calculated as:
⇒ 
⇒ 
The new increased average price actually is = $135,000
So, we have,
Dividing both sides by 1.085
∴ 
Thus average price of a house last year was = $124,423.96
