Naya [18.7K]

Solution: Let x be the amount to be invested (15%).

Then,

x*0.15 + 550*0.11 = (x+550)*0.12

x*0.15 - x*0.12 = 550*0.12 - 550*0.11

0.03x = 550*(0.12-0.11)

0.03x = 550*0.01

0.03x = 5.5

x =5.5÷0.03

x=183.33

Answer: $183.33 more to be invested for 12 % total return.

Step-by-step explanation:

Take 2 points (0,0) and (-3,6)

m(slope)= m = rise/run = y2 - y1/ x2 - x1

y2-y1= 6-0=6

x2-x1 = -3-0 = -3

Don't know how to solve this problem, help would be appreciated
kenny6666 [7]

Answer:

219

Step-by-step explanation:

The figure has the shape of a trapezoid. We find the area of the trapezoid and subtract the area of the rectangular door.

area of trapezoid = (base1 + base2)h/2

area of trapezoid = (20 ft + 12 ft) * 15 ft / 2

area of trapezoid = 32 ft * 15 ft /2

area of trapezoid = 240 ft^2

area of rectangle = length * width

area of rectangle = 7 ft * 3 ft

area of rectangle = 21 ft^2

area to be painted = area of trapezoid - area of rectangle

area to be painted = 240 ft^2 - 21 ft^2

area to be painted = 219 ft^2

Answer: 219 ft^2
