Simplify each term
Answer: 6.25
Step-by-step explanation:
Because corresponding sides of similar triangles are proportional,
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
Add the total faces: 30 + 20 + 12 = 62
Using the given equation: V + F = E +2
You have F = 62, V = 120
Now solve for E:
120 + 62 = E +2
Simplify:
182 = E +2
Subtract 2 from both sides:
E = 182 - 2
E = 180
It has 180 edges.
Answer: both are 21/29
Step-by-step explanation:
Use SOHCAHTOA so the opposite/hypotenuse for P is 21/29 and the adjacent/hypotenuse for Q is also 21/29
