Answer:240 square centimeters
Step-by-step explanation:
1. 10x7=70
2. 7x10=70
3. 25x4=100
70+70+100=240
(Are you saying the king case is an additional 12% of $84? I think you should word the question a bit more clearly).
12% = 12/100 = 0.12 multiplied by $84 = $10.08 = $84 + $10.08 = $94.08
We have $94.08 so far (king case and camera price combined).
Tax is 6%, so 6/100 = 0.06 multiplied by $94.08 = $5.64
Add $5.64 to the $94.08 total we calculated.
$94.08 + $5.64 = $99.72 <=== this is our total cost plus tax.

Hello! I can help you with this!
a. To find out how much Mary saved, we will have to subtract the sale price from the original price, and then add up the difference to find how much she saved. 62 - 48 is 14. 46 - 34 is 12. 14 + 12 = 26. Mary saved $26 by buying at the sale item price.
b. To find the amount of discount, we can write and solve a proportion, by setting it up like this: change/original = x/100. Change is the distance between two numbers and the original is the previous price. If you know about proportions, you cross multiply the values, and then divide each side by a number to isolate "x". If you solve each proportion correctly, here are your answers for each item:
Dress: ≈ 23% discount
Shoes: ≈ 26% discount
c. Okay. So when we add up the sales prices together, 48 + 34 is 82. In order to find the total amount with tax, we multiply the sale price, by (1 + r). In other words, add 1 to the rate in decimal form and multiply it by the total of the sales price. 82 * 106.5% (1.065) is 87.33. Mary paid a total of $87.33.
Answer:

Step-by-step explanation:
1) The radius is 10
2) Perimeter basically means circumference
3) The formula for circumference is 2πr
4) 2π*10
5)2*pi=6.28*10=62.8
