Answer:

Step-by-step explanation:

The angles of any triangle add up to 180 degrees.

$8x + (7x+2) + (4x+7) = 180 \\ 19x+9=180 \\ 19x=181 \\ x=9$

Putting this value into the expressions for the angle measures:

$m\angle J=7x+2=65 \\ m\angle K=8x=72\\m\angle L=4x+7=43$

Whitepunk [10]

Answer:

13.79%

Step-by-step explanation:

A solution is made by dissolving 24 millimeters of saline in 150 millimeters of pure solution

Therefore percent of saline in the pure solution can be calculated as follows

= 24/24+150 × 100

= 24/174 ×100

= 0.1379 ×100

= 13.79%

Hence the percent of saline in the pure solution is 13.79%

a department store holds a year-end clearance sale that includes a 19.8% discount on cosmetics. find the sale price of a bottle

Ivan

The sale price of a bottle of perfume is $40.16 if its original price was 50.07%.

What is discount?

By paying a charge or fee, a debtor might purchase the right to postpone payments to a creditor for a predetermined length of time through the financial mechanism known as discounting. In essence, the party who is currently owing money purchases the right to postpone payment until a later time.

Let the original price of the perfume bottle is, $50.07

The sale on the cosmetics is 19.8%.

So, the discount on the perfume bottle is,

50.07 x 0.198 = 9.91368

Therefore, the sale price of perfume is,

$50.07 - $9.91368 = $40.15614

Hence, the sale price of perfume is, $40.16
