The way I picture this thing, it's made of three rectangles
that are joined together.
-- One rectangle is 3 x 6 meters.
-- One rectangle is 3 x 8 meters.
-- One rectangle is 3 x 10 meters.
-- Their 3-meter edges are all taped together to make a 'tube'.
-- It's 3 meters long, and it has 3 sides.
-- When you look at the ends of the tube, they're both
right triangles with sides of 6, 8, and 10 meters.
-- The area of each side = 1/2 (base x height)
= 1/2(6m x 8m) = 24 square meters.
2 ends = 48 square meters.
-- The lateral surface area is the area of the three rectangles
that make the 'tube'.
-- Area of the 6 x 3 rectangle = 18 square meters
-- Area of the 8 x 3 rectangle = 24 square meters
-- Area of the 10 x 3 rectangle = 30 square meters
-- Total lateral area = (18 + 24 + 30) = 72 square meters.
-- When you add the ends to it, you get
(72 + 48) = 120 square meters
for the total area.
I'd still double check with someone on this but I believe that the answer is ×=(-6/5m+3/5p) I'd still double check but I'd ur in a big hurry and just need it done then put that

Answer:
1.048
Step-by-step explanation:
The generic form of the exponential model is ...
y = a·b^x
Filling in the given values, we have ...
100 = a·b^6
184 = a·b^19
__
Dividing the second equation by the first gives ...
184/100 = (a·b^19)/(a·b^6)
1.84 = b^13 . . . . . simplify
b = 1.84^(1/13) ≈ 1.048022 . . . . find the 13th root
The growth factor is about 1.048.
Answer:
Its2 for every 3
Step-by-step explanation:
The interest is computed from
... I = Prt
where P is the principal amount ($569), r is the rate (0.045) and t is the time in years (250/360).
... I = $569×0.045×250/360 ≈ $17.78
Please note that time is not rounded. Rather, the exact value (25/36) is used in the calculation. The only rounding of any number is done at the end, where the amount is rounded to the nearest cent. (Your text authors should know this.)
_____
If you follow the problem instructions (which Valerie's lender will <em>not</em> do), the interest is calculated as ...
... t = 250/360 = 0.6944444... ≈ 0.69 . . . . years
... I = $569×0.045×0.69 ≈ $17.67
_____
Note the rounding of intermediate numbers (time) introduces an error of about $0.11 in the answer.
