Answer:
Step-by-step explanation:
If you are saving 25%, you are still paying 75%, right? So the cost of the TV with a discount of 25% is 192.74(.75) which is $144.56
That's the cost of the TV on sale. Now we need to find the sales tax amount, if the sales tax is .05 as a decimal. We are paying $144.56 for the TV, which is 100% of the cost. On top of that, we are paying another 5%. So altogether, for the TV, we are paying 105% of the TV. Therefore,
144.56(1.05) = $151.79
8 = 1. The relationship equation is y = x - 7
Answer:
The surface area of the square pyramid if the slant height is 13mm and the base length is 11mm is 407 sq.mm.
Step-by-step explanation:
Slant height of square pyramid = l = 13 mm
Base length of square pyramid = b = 11 mm
Formula of surface area of square pyramid =
Substitute the values in the formula :
Surface area of square pyramid =
Surface area of square pyramid =407 sq.mm.
Hence the surface area of the square pyramid if the slant height is 13mm and the base length is 11mm is 407 sq.mm.
