Hello:

the equation is : y = ax+b

the slope is a : a×(2/7) = -1......( perpendicular to a line with a slope of 2/7) because : 2x-7y =-42...y=(2/7)x+6 )

a = -7/2 y=(-7/2)x+b

the line that passes through (6, -3) :- 3 = (-7/2)(6)+b

b =18

the equation is : y = (-7/2)x+18

trap door = 130 square feet.

1st item: 6ft 5in wide & 8ft 9in long

⇒ (6ft * 12 in) + 5 in & (8ft *12 in) + 9 in

⇒ 77inches by 105 inches

⇒ 8,085 square inches

2nd item: 13ft 4in wide & 7ft 8in long

⇒ (13ft * 12in)+ 4 in & (7ft *12in) + 8 in

⇒ 160 inches by 92 inches

⇒ 14,720 square inches

3rd item: 5ft 6in wide & 12ft 4in long

⇒ (5 ft * 12in) + 6 in & (12ft * 12in) + 4in

⇒ 66 inches by 148 inches

⇒ 9,768 square inches

130 square feet convert to square inches.

130 sq. ft * 144 sq.in/sq.ft = 18,720 sq. in

18,720 sq. in / 160 inches = 117 inches

Length = 160 inches ; Width = 117 inches

Perimeter = 2(160 + 117)

P = 2(277)

P = 554 inches

P = 2(277)

P = 554 inches

QUESTION POSTED AT 01/04/2020 - 01:38 PM

**Answer:**

**$ 416.70 ( approx )**

**Step-by-step explanation:**

Given,

The monthly income = $ 2,415.64,

**Discretionary monies** (Money left after expenses) = 54 % of the monthly income

⇒** **Fixed expenses for a month** **= (100-54)% of total monthly income

= 46 % of total monthly income

= 0.46 × 2,415.64

= $ 1,111.1944

Thus, **the fixed expenses of 3 months** = 3 × fixed expenses for a month

=** **3 × 1,110.5544 = **$ 3331.6632**

Since, this money is saved in **8 months**,

Hence, **the amount of money saved per month** = 1/8 of $ 3331.6632

= $ 416.6979 ≈ **$ 416.70**
