Lannie ordered 12 copies of the same book for his book club members. The book cost $19 each, and the order has a $15 shipping ch
SashulF [63]

Hey there!

First, we need to find how much Lannie paid for all 12 copies. To do this, all we have to do is multiply the unit price ($19) by how many copies he bought (12)

$19 x 12 = $228

So, he spent $228 on the books, but we also need at add the shipping charge:

$228 + $15 = $243

Therefore, the total cost of Lannie’s order is $243

Hope this helps you!

God bless ❤️

5/8<br> of a sum of money is $240. What is the value of the sum of money?
Reika [66]

Answer:

The total amount is 384

Step-by-step explanation:

Let m = the amount of money

5/8 of the money is 240

5/8 * m = 240

Multiply each side by 8/5

8/5 * 5/8 * m = 8/5 * 240

m =384

The total amount is 384

If each quadrilateral below is a parallelogram,find the missing measures
Rufina [12.5K]

Answer:

Step-by-step explanation:

We will use parallelogram properties to answer our given problems.

(1) Since we know that opposite sides of parallelogram are congruent, therefore measure of side MN and side KN will be equal to the measure of their opposite sides.

LM=KN   and   KL=MN

Upon substituting our given values we will get,

45=KN   and   31=MN

Property: The opposite angles of parallelogram are congruent and consecutive angles are supplementary.

We have been given , therefore .

We will find measure of angle K by using supplementary angles.

By opposite angles of parallelogram .

(2) Opposite sides of parallelogram are equal. Therefore, CF=DE and FE=CD.

Upon substituting our given values we will get,

CF=10  and FE=15.

Property: Diagonals of parallelogram bisect each other.

So CE will be 2 times CG and GD will be half the length of FD.

(3) Property: Opposite sides of parallelogram are congruent.

  and  

Upon substituting our given values we will get,

  and  

Property: Diagonals of parallelogram bisect each other.

So SQ will be 2 times TQ and PT will be half the length of PR.

Property: The opposite angles of parallelogram are congruent and consecutive angles are supplementary.

 Alternate interior angles.

Opposite angles of parallelogram.

Therefore, measure of angle QRS will 74 degrees.

Alternate interior angles.

Now let us find measure of angle PSQ.

The image is not clear, so I am unable to answer the last two problems.
