Answer:
h = 12 m
Step-by-step explanation:
Sides of the triangle are proportional.
(3.6 m)/(1.2 m) = h/(1.2 m + 2.8 m)
(4 m)(3.6/1.2) = h . . . . . multiply by 4 m
h = 12 m
Let w represent the width of the rectangle in cm. Then its length in cm is (3w+9). The perimeter is the sum of two lengths and two widths, so is ...
... 418 = 2(w + (3w+9))
... 209 = 4w +9 . . . . . . divide by 2, collect terms
... 200 = 4w . . . . . . . . subtract 9
... 50 = w . . . . . . . . . . divide by 4
... length = 3w+9 = 3·50 +9 = 159
The dimensions of this piece of land are 159 cm by 50 cm.
Answer:
They are both the same
Step-by-step explanation:
$2.40 / 6 = .40 which means that each bottle costs 40 cents. $3.20 / 8 = .40 as well which is also 40 cents so therefore neither one is better that the other
The answer that you will get is 19/3
Yo sup??
a.Just draw any triangle which has its sides as 3x,4x and 5x where x is any variable.
if x=1 we get the given triangle ie 3,4 and 5
if x=2 we get a similar triangle ie 6,8 and 10
if x=3 we get another similar triangle and so on.
b.Sam will be correct when all the 3 sides of the two triangles are also equal whereas Delaney will always be correct in the rest of the possible cases.
Hope this helps
