Here is the solution on how much the total amount that Lisa paid:The total amount for all the items is $53: $10 + $20 + $23 = $53 Now, 7.2% = 0.072 Compute for the sales tax of each item:$10 x 0.072 = .72 $20 x 0.072 = 1.44 $23 x 0.072 = 1.66 The total sales tax would be: .72 + 1.44 + 1.66 = $3.82 Now add the Sales tax to the total price of the items. $53 + 3.82 = $56.82Therefore, Lisa paid $56.82.
Answer:
189.8 m
Step-by-step explanation:
See the diagram attached.
Now, the plane is at B and the two ships are at C and at D.
So, angle of depression of C from B is ∠ OBC = ∠ ACB = 35°
Again, the angle of depression of D from B is ∠ OBD = ∠ ADB = 25° ,
Now, from the right triangle Δ ACB,
⇒ m.
Similarly, from the right triangle Δ ADB,
⇒ m.
Hence, the distance between the ships = CD = AD - AC = 568.3 - 378.5 = 189.8 m (Approx.) (Answer)

Answer:
n = 99
Step-by-step explanation:
The sum of logarithms is the log of a product. Here, the sum of terms is ...
log(2/1) +log(3/2) +log(4/3) + ... +log((n+1)/n)
= log((2/1)(3/2)(4/3)×...×((n+1)/n)) = log(n+1)
So, the question reduces to ...
log(n+1) = 2
Taking antilogs, we have ...
n +1 = 10^2 = 100
n = 99
The value of n that makes the sum 2 is 99.
