Hey!Can somebody help me please?
1) Divide 49p in the ratio 4:2:1
2) Divide £350 in the ratio 4:2:1
4) Divide 120cm in the ratio 1:2:3
3) Divide £250 in
the ratio 3:6:1

I only know the first one

4+2+1=7

49p/7= 7p

4units:2units:1units

4×7p= 28p

2×7p= 14p

1×7p= 7p

divided it is...

28p:14p:7p

i do not know this sorry : (

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
