What is the length of the hypotenuse?

75 is the hypotenuse

Step-by-step explanation:

Since a square plus b square is c square then you substitute it. So it would be 45 square plus 60 square equals c square. 45 square is 2025 and 60 square is 3600, you add them and it's 5625. Now you have to find the square roots of 5625, which is 75. The answer s 75.

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.
