loris [4]

Answer:

The cost of the baseball cards cost with the discount is $17.1.

Step-by-step explanation:

Given : Jules purchased a box of baseball cards for her collection. The original price was $22.80, but the store was having a sale with $\frac{1}{4}$ off the price of all baseball cards.

To find : How much did the baseball cards cost with the discount?

Solution : The original price of baseball cards is $22.80

There is off of $\frac{1}{4}$ of the original price.

First we find the discount on original price

$22.80\times\frac{1}{4}=5.7$

Discount is $5.7

So, The cost of the baseball cards cost with the discount is

Cost = Original - Discounted

Cost = $22.80 - $5.7

Cost = $17.1

Therefore, The cost of the baseball cards cost with the discount is $17.1.

If JL = 30, JK = 18, and LM = 6, then the value of LN is:

harina [27]

Answer:

LN = 15

Step-by-step explanation:

The arrows on the line segments indicate they are parallel.

$\implies \overline{KM} \parallel \overline{JN}$

Triangle Proportionality Theorem

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then it divides these two sides proportionally.

$\textsf{If }\overline{KM} \parallel \overline{JN}, \textsf{ then }\dfrac{LK}{LJ}=\dfrac{LM}{LN}$

Given:

LM = 6
JL = 30
JK = 18

⇒ LK = JL - JK = 30 - 18 = 12

Substituting the values into the equation and solving for LN:

$\begin{aligned}\implies \dfrac{LK}{LJ} & = \dfrac{LM}{LN}\\\\\dfrac{12}{30} & = \dfrac{6}{LN}\\\\12LN & = 30 \cdot 6\\\\LN & = \dfrac{180}{12}\\\\LN & = 15\end{aligned}$
