Problem page the price of a notebook has dropped to $3.20 today. Yesterday's price was $3.45 . Find the percentage decrease. Rou
Anna11 [10]

Yesterday's price of notebook = $3.45

Today's price of notebook = $3.20

We have to determine the percentage decrease in the cost of notebook.

Percentage decrease = (Decrease \div Old price) \times 100

So, percentage decrease = \frac{3.45-3.20}{3.45} \times 100

=\frac{0.25}{3.45} \times 100

= 7.246%

= 7.25%

Therefore, there is 7.25% of decrease in the cost of the notebook.

**HELP**<br>find the angle measures given the figure is a rhombus.​
DIA [1.3K]

Answer:

m<1=74

m<2=37

Step-by-step explanation:

m<2 is the same as the other angle, 37 degrees. So now we need to find the other angle in the triangle.

37+37+x=180.

The total degree of a triangle is 180.

x=106

Subtract that from 180 to get m<1.

180-106=74

I hope this helps!

Good luck!
