two of the shortest sides of a pennant shaped like a right triangle measure 10 inches 24 inches hank wants to put colored tape around the edge of the pennant find how many of tape hank needs

60

Plz give Brainiest!

Step-by-step explanation:

okay, so we know that 2 sides of the triangle measure 24 in. and 10 in. if I got the info correct, kind of hard to read and understand it. We can use the Pythagorean theorem to solve this. The Pythagorean theorem is .

now, we put in 24 and 10 for a and b.

We try to figure out what c is.

= 576 + 100 =

= 676 =

Now we need to square root both sides to find the amount of c.

=

The square root of 676 is 26!

Now, you just need to add 24 + 26 + 10 = 60!

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
