8 times 3 is 21 so 3 juries
Tan(35)=x/12
x=12*tan(35)=8.40
Answer:
Each would pay $20.94
Step-by-step explanation:
Step 1: Find the total for the bill including the tip.
The bill is $52.35. To calculate 20% of this, multiply by 0.2 (or 20/100)
The tip is ($52.35)(0.2) = $10.47
Step 2: Add the tip to the total bill.
$52.35 + $10.47 = $62.82
Step 3: Divide the total bill by the number of people splitting the bill, in this case, 3
$62.82/3 = $20.94 per person
Think of 10^2, 10^1, and 10^0 as x^2, x^1, and x^0.
When you add polynomials, you can only combine like terms.
When you add expanded numbers, you can only combine like powers of 10.
123 + 423 =
= (100 + 20 + 3) + (400 + 20 + 3)
= (1 * 10^2 + 2 * 10^1 + 3 * 10^0) + (4 * 10^2 + 2 * 10^1 + 3 * 10^0)
= (1 * 10^2 + 4 * 10^2) + (2 * 10^1 + 2 * 10^1) + (3 * 10^0 + 3 * 10^0)
= 5 * 10^2 + 4 * 10^1 + 6 * 10^0
= 500 + 40 + 6
= 546
It is already in simplest form, however it can be written as .5 and 50%.
