 <span>The fifth power of ten would not be represented. 
Each individual digit would be shown as a power of ten. 
982 would be the sum of: 
9 times 100. (100 is 10 to the second power) 
plus 
8 times 10. (10 is 10 to the first power.) 
plus 
2 times 1. (I is 10 to the zero power.) 

The only significant digit represented by a zero is the "hundred thousands" 
(100,000 is 10 to the fifth power.)</span>

Johnny bought an oil painting originally priced at $80 but on sale for for 50% off. After 10% sales tax, what was the total cost
Alecsey [184]

Answer:

$44

Step-by-step explanation:

Original price = $80

Discount on sale = 50%

Discounted price = (1 - 50%) * original price

Discounted price = 0.5 * $80 = $40

Sales tax = 10%

Sales tax amount = 0.1 * $40 = $4

Total cost = discounted price + sales tax amount

Total cost = $40 + $4 = $44

Write the equation of a line with a slope of 5 and contains the point (-6, 2)
tigry1 [53]
I think the answer would be y=5x-3/5. You would use the point slope formula(y=mx+b) and plug in 5 for m and the x and y of the point for x and y. Solve for b and the plug in b and 5 into the point slope formula to get the answer! Hope it helps!!
