The legs of a right triangle measures 9ft and 12ft. What is the length of the hypotenuse

The hypotenuse would be 15ft

Step-by-step explanation:

You would use pythagorean theorum which would make the equation 9²+12²=c²

next step would be to make it √81+144=c²

then you would get √225=c²

then you just calculate the square root of 225 and you have your answer.

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
