C) Share £160 in the ratio 1:9
(2)
Answer £
and £

£16:£144

Step-by-step explanation:

1+9=10

160/10=16

1×16=16

9×16=£144

16£ and 114£

Step-by-step explanation:

add the ratios

1 + 9 = 10

for the first ratio

(1/10) × 160

= 16£

for the second ratio

(9/10) × 160

= 114£

ik how do do this just give me a few minutes and i will give it to

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
