Answer:
$3.88
Step-by-step explanation:
You want to leave a 18% tip on a meal that cost $21.58.
First, convert the 18% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.
Second, you need to find out what 18% of your $21.58 meal cost is.This is always done by multiplying 0.18 by $21.58, or 0.18 x $21.58=$3.88.
So, the amount of tip you are going to leave is $3.88.

Answer:
21
Step-by-step explanation:
dog = 35/85 = x/51
=> x = 35 x 51 / 85 = 7 x 51 / 17 = 21
Pyramid Volume = (Area of the Base * Height) ÷ 3
Height = 3 * Volume / (Area of Base)
Height = 3 * 216 / 36
Height = 18 cm
