Answer: $160
Step-by-step explanation:
You'll need to find the mark-up price first: $2400+1/3
1/3= $800
$2400+$800= $3200
$3200 is the mark-up price
Then you have to find the discount:
1/5 of $3200
$3200/5= $640
$3200-$640= $2560
Lastly, you have to find the profit:
$2560-$2400= 160
Answer:
Factors: 5x, 3x²y⁵ Not Factor: 10x⁴y³
Step-by-step explanation:
5x is a factor because 15x²y⁶= 5x•3xy⁶
3x²y⁵ is a factor because 15x²y⁶ = 3x²y⁵•5y
10x⁴y³ isn't a factor because 15:10=1.5 isn't integer
Answer:
D. Angles 4 and 7
Step-by-step explanation:
The answer is 8/5.
When multiplying fractions you multiply the top numbers (Numerators) and then the bottom numbers (Denominators).
4 * 6 = 24, 3 * 5 = 15. So we have 24/15. We can simplify this since both 24 and 15 are divisible by 3. Divide both the top and bottom number by 3 to get 24/15 = 8/5.
