points A, B, C and D lie on a line segment in that order. If AB=CD=9. If the ratio of AB to BC is 1:3, what is the length of AD?

Step-by-step explanation:

So as the usual we can see that

Ab=9 and cd=9

And we can get bc by

ration reading 1

So AB:BC=1:3

SO we said that AB is 9 so we have to multiply The ratio by 9:9 we can see that the ratio will be AB:CD=9:27 the main thing here is we have got the BC which Is 27

So AD means the sum of all Points

AB+BC+CD=AD

9+27+9=AD

AD=45

Thanks in Advance

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
