The kite is directly 35.707 yards high above Erika

Step-by-step explanation:

Given scenario forms a right triangle where the length of string is the hypotenuse and the distance between Mary and Erika is the base.

So

H = 50\ yards\\B = 35\ yards

We have to find the perpendicular

Using pythagoras theorem,

H^2 = B^2 + P^2

Putting the values

(50)^2 = (35)^2 + P^2\\2500 = 1225 + P^2\\P^2 = 1275\\

Taking square root on both sides

\sqrt{P^2} = \sqrt{1275}\\P= 35.707

Hence,

The kite is directly 35.707 yards high above Erika

Can someone help me with this math question?
inessss [21]

Answer:

  see attachment

Step-by-step explanation:

It is convenient to use a spreadsheet for this purpose.

The first row of numbers is constant at $45, as there is no daily charge associated with that payment method.

The second row of numbers uses the formula ...

  cost = $12 + $4×(number of days)

The third row of numbers uses the formula ...

  cost = $6×(number of days)

___

Of course, you can use these formulas to fill in the numbers by hand. For example, for 15 days, the charges are ...

  • Early Pay: $45 (no calculation necessary)
  • Deposit Plus: $12 + $4×15 = $12 +60 = $72
  • Daily Pay: $6×15 = $90
