Sally is 148cm tall. The ratio of Sally to the height of the apple tree in her garden is 1:2. How tall in meters is the apple tree?

so the height of apple tree in meters is 3 meters

Step-by-step explanation:

by using ratio and proportion rule

1:2=148:x

by cross multiplication

1×x=2×148

1x=296cm

converting into meter as we know that 1centi=10^-2

1x=296×10^-2

x=2.96m≈3meters

i hope this will help you :)

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
