To the nearest hundredth, what is the measure of line segment rt?

9.75

Step-by-step explanation:

To solve for RT, we use the Pythagorean Theorem. aka, a^2+b^2=c^2. We know a and c, but not b. That's okay because we can plug in what we do know and solve. We now get 7^2+b^2=12^2, or 49+b^2=144. We can subtract 49 from both sides to get b^2=95. Now, to get b by itself, we must do the opposite of squaring, which is the square root. Putting the square root of 95 into a calculator and rounding to the nearest hundredth, we get b=9.75. So, the length of RT is 9.75

207/8 is the right

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!
