Televisions are on sale for 40% OFF the original price of $600. After tax (8.5%) is applied, what is the final price?

FromTheMoon [43]

First, determine what is 40% of $600. Multiple 40 (as a decimal) by 600.

0.4 x 600 = 240

Therefore, the discount is $240 off $600.

Subtract the two values to find price (before tax): 600 - 240 = 360

So the TV will cost $360 before tax.

The tax is 8.5%. Multiply 8.5 as a decimal by 360 to find the amount of tax added.

0.085 x 360 = 30.6

Add 30.6 and the price before tax to find the final price.

30.6 + 360 = 390.60

Therefore, the final price of the TV is $390.60

A farmer has a rectangular plot of land. There is a bother identical plot of land 100 yards east and 100 yards north. Find the c

Anna [14]

Answer:

Step-by-step explanation:

Area of a rectangular plot = Length × width

With the aid of the diagram attached below.

For plot 1:

The area = ( 60 - 20 ) × ( 80 - 20 )

Area = 40 × 60

Area = 2400 sq yard

For plot 2:

Area = (160 - 120 ) × ( 180 - 120 )

Area = 40 × 60

Area = 2400 sq yard

Therefore, the combined area of the two plots of land = 2400 + 2400

= 4800 square yards

Step-by-step explanation:

Sin(angle) = Opp/Hyp

Sin44 = 10/BC

0.6947 = 10/BC

Cross multiply

BC 0.6947 = 10

Divide both side by 0.6947

BC = 14.39
