The answer to your question is 5 and 1.
Have a nice day :)
88.83 / 21 = 4.23
4.23 is the same number as 423% .
8.23 is <em>423%</em> of 21.
Slope = -2
Point-slope equation for line of slope -2 that passes through (1,8):
y-8 = -2(x-1)
Solve for y
y = -2x+10
y-intercept = 10
The fact that the slopes of HF and GH are negative reciprocals proves that FGH is a right triangle.
The slope of HF is given by
m = (-4-4)/(-3-2) = -8/-5 = 8/5
The slope of GH is given by
m = (-4--9)/(-3-5) = (-4+9)/(-3-5) = 5/-8 = -5/8
These are reciprocals and opposite sides. This only occurs if the lines are perpendicular; thus they make a right angle.
Answer:
Using the formula to calculate the area of a square, the side of the patio can be 11.4 ft.
Step-by-step explanation:
Square patio
Area: A=130 square feet= 130 ft^2
Side of the square: s=?
The formula to calculate the area of a square is:
A = s^2
Replacing A by 130 ft^2
130 ft^2 = s^2
Solving for s: Square root both sides of the equation above:
sqrt(130 ft^2) = sqrt(s^2)
11.40175425 ft = s
s = 11.40175425
Rounding to the nearest tenth:
s = 11.4 ft
