Answer:
10 : 9
Step-by-step explanation:
Given that a retailer sold a vacuum cleaner for 40% below its marked price.
Let the marked price = P
40% below = (100 - 40)P/100
Sale price = 60P/100
Sale price = 0.6P
The sale price was 50% above the cost to the retailer.
That is, cost price = (100 + 50)0.6P/100
Cost price = (150)0.6P/100
Cost price = 1.5 × 0.6P
Cost price = 0.9P
What is the ratio of marked price to cost?
The ratio will be = P/0.9P
Multiply both the numerator and denominator by 10
Ratio = 10 : 9
4 hours is $50, 40 hours is $500, 160 hours is $2000, 200 hours is $2500.
i’m pretty sure this is right because she makes $12.5 an hour.
Answer:
100 is the square root of 10,000. And 3,136 for the 2nd one.
Step-by-step explanation:
A square root is one number multiplied by the same number to get a specific product. 100 x 100 = 10,000, therefore being the square root of 10,000.
56 x 56 is the same as 56 to the second power, which equals 3,136.
