First we are going to start by subtracting 3-10 and that gives us 7 so then you divide 7 by 4”3 and you get 2.3
(12)(20)= 240
The answer is going to be B. 240 sq ft
Look at it this way 1(700)*1(20). can u do it now?
Slope-intercept form is y = mx + b, where the variable m represents the slope of the line and the variable b represents the y-intercept. Because we are given these values, all we have to do is plug in the given values into the equation for their respective variables.
y = mx + b
y = -5x + 8
Therefore, your answer is y = -5x + 8.
Hope this helps!
Answer:
(a) 12.96 ft²
(b) 21.5 in²
Step-by-step explanation:
(a) For the first diagram
Area of the shaded region (A) = Area of Tripezium- area of circle
A = [1/2(a+b)h]-[πr²]............... Equation 1
Where a and b are the parallel side of the tripezium respectively, h = height of the tripezium, r = radius of the circle.
From the diagram,
Given: a = 15 ft, b = 6 ft, h = 12 ft, r = h/2 = 12/2 = 6 ft.
Constant: π = 3.14
Substitute these values into equation 1
A = [12(15+6)/2]-(3.14×6²)
A = 126-113.04
A = 12.96 ft²
(b) For the second diagram,
Area of the shaded region (A') = Area of square- area of circle
A' = (L²)-(πr²)............. Equation 2
Where L = lenght of one side of the square, r = radius of the circle
From the diagram,
Given: L = 2r = (2×5) = 10 in, r = 5 in
Substitute these values into equation 2
A' = (10²)-(3.14×5²)
A' = 100-78.5
A = 21.5 in²
