Answer:
63.72 ft^2
128 cm^2
Step-by-step explanation:
5. The area of a triangle is
A = 1/2 bh where b is the base and h is the height
A = 1/2(21.6) * (5.9)
= 63.72 ft^2
6. The scale factor is 20/15 = 4/3
When we find area is the scale factor is squares
(4/3) ^2 = 16/9
Taking the ratio of the areas
A big trap
------------------- = scale factor squared
A little trap
A big trap 16
-------------- = ------
72 9
Using cross products
9A = 16*72
9A = 1152
Divide each side by 9
A = 1152/9
A =128
The area of the large trapezoid is 128 cm^2
Answer:
y = -2x + 5
slope = -2
y intercept = 5
Step-by-step explanation:
Slope intercept form of equation of line is given by y = mx + c
where m is the slope of line
c is the y intercept i.e point where given line intersect y axis.
________________________________________________
given equation 4x + 2y = 10
we have to re-write this equation in form y = mx + c
4x + 2y = 10
subtraction 4x from LHS and RHS
4x + 2y - 4x= 10 - 4x
2y = 10- 4x
we have to eliminate 2 from y for that we
divide LHS and RHS by 2 we
2y /2 = 10/2- 4x/2
y = 5 - 2x
rearranging it in y = mx+c form
y = -2x + 5
thus, m = -2 , c = 5
