Answer:

Bonnie needs 67.8\ in of ribbon

Step-by-step explanation:

we know that

A Kite is a quadrilateral that has two pairs of equal sides

so

To find out how much ribbon Bonnie needs calculate the perimeter of the kite

P=2(L1+L2)

where

L1 is the length of one side

L2 is the length of the other side

P=2(13.2+20.7)=67.8\ in

Find the sum of a finite arithmetic sequence from n = 1 to n = 10, using the expression 3n − 8.
maw [93]

Answer:

The answer is 85

Step-by-step explanation:

The equation used to find the sum of an arithmetic series is: (n/2) * (a1 + an).

n in this case is 10 (the number of numbers in the series)

an is 22 (plug in 10 to the expression 3n-8)

and a1 is -5 (plug in 1 to the expression 3n-8)

so when you plug everything in to the final equation, you get

(10/2) * (-5 + 22)

5 * 17

85

<h3 /><h3>Pet fish</h3>

The following represents the items bought

  • Each bag has m mollies and 1 bala
  • He bought 3 of these bags

The expression that represents the items in a bag is:

Bag=m + 1\\

He bought 3 bags.

So, the total spent on pet fish is:

Total =3(m + 1)

<h3>Fish food</h3>

A box costs d dollars.

This means that, the total amount Mr Green spent in the store is:

Total =3(m + 1) + d
