The formula for area of a square is s^2 so it would be 7; the perimeter would be 7+7+7+7= 28 and the area would be 7^2= 49
Answer:
66.00
Step-by-step explanation:
Convert 10% to a decimal by moving the point from 10. to 0.10 (back two places) and multiply it by 50 which gives you $5, which equals the tax they payed. Now they want to tip 20% of the entire bill including tax, so convert 20% to a decimal 20. to 0.20. Now multiply .20 * 55(55 is the $50 payed in meals and the $5 payed in taxes added) And you get $11 for the tip. Add 55 +11 and there's your answer
3.49/25 = $0.14 per ounce
4.79/40 = $0.12 per ounce
Choice B has a lower price per ounce
Answer: D) x - 0.2x
Step-by-step explanation:
The hat has a regular price of x dollars.
This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x
The discounted price will be the price of the hat less the discount which means the formula will be;
= Price - discount
= x - 0.2x
