Select the shapes that are similar to shape a.

A , B and C are similar to each other

Step-by-step explanation:

Let us analyse the Figure A :

Base = 2 units

Height = 1 units

shorter slant height =

Figure B

Base = 2 units

Height = 1 units

shorter slant height =

Figure C :

Base = 3 units

Height = 1.5 units

shorter slant height =

Hence we see that the three figures are similar to each other as the ratio of three sides of A to those of B is 1

and the ratio of three sides of A to those of c is 1.5

step-by-step explanation:

3

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!
