A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 907.46 square feet? Use 3.14 for π
Answer:
The number of feet away from the sprinkler where it could spread water would be the radius of the circle in which it is spraying.
The Area of a circle is
πr2=808.64
(3.14)r2=808.64
Divide both sides by 3.14
r2=257.5286624
Square root both sides to get radius
r=16 feet
7 feet away from the sprinkler can it spread water if the area formed by the watering pattern is 907.46 square feet
Area of circle:What information do we have?
Area of watering pattern = 907.46 square feet
Area of watering pattern = Area of circle
Area of watering pattern = πr²
907.46 = (3.14)r²
r² = 289
r = 17
Length = 17 feet

what is the area of the triangle
Answer:
4 units²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A= [tex]\frac{1}2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 4 and h = 2 , then
A = [tex]\frac{1}{2}[/tex] × 4 × 2 = 2 × 2 = 4 units²

The endpoints of directed line segment PQ have coordinates of P (-7, -5) and Q (5, 3). What are the coordinates of point A, on segment PQ, that divide segment PQ into a ratio of 1:3?
Answer:
(2,1)
Step-by-step explanation:
The coordinate point between two points divided between ratio a and b is expressed as;
(X, Y) = [(ax1+bx2/a+b,ay1+by2/a+b]
Given the coordinate points (-7,-5) and (5,3) divided within the ratio 1:3
X = ax1+bx2/a+b
X = 1(-7)+3(5)/1+3
X = -7+15/4
X = 8/4
X = 3
Similarly
Y = ay1+by2/a+b
Y = 1(-5)+3(3)/1+3
Y = -5+9/4
Y = 4/4
Y = 1
Hence the required coordinate point is (2,1)

Find the value of 1.999.... in the form of p
q
where p and q are integers.
1.999… is exactly the number 2.
Let x = 1.999… . Then 1000x = 1999.999… . Subtract x from this to eliminate the fractional part, and you get
1000x - x = 1999.999… - 1.999…
1000x - x = 1999 - 1
999x = 1998
x = 1998/999 = 2/1 = 2
So p = 2 and q = 1.
