The ratio of the base to the height of a triangle is 5:3. The area of the triangle is 120cm. How long is the base?

20 cm

Step-by-step explanation:

5n × 3n = 2×120

15n²=240

n²=240/15 =16

n=√16 = 4

base = 5× 4 = 20

line one b=h*5/3

line two b*h/2=120

let's substitute b in line two with the righthand side of line one

(h*5/3)*h/2=120

h²*5/6=120

h²=(120/5)*6

h²=144

h=12

(the negative solution of the root is ignored, bc h is some distance. distances are never negative)

let's plus 12 into line two, in the place of h. this will give us b

b*12/2=120

b*6=120

b=20

h=12 and b=20 are in the right ratio (note that both are multiples of 4, 12=4*3 and 20=4*5)

and 12*20/2 = 120

everything works out just nicely

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
