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

answer: ok

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
