If 3 people go to lunch and the bill was $30 and they all give $10 and the waitress comes back with the waitress comes back and
Kryger [21]

Answer

No missing money

Step-by-step explanation:

Original money given to the waiter = $30

Each person paid $10

The waitress comes back with the waitress comes back and said the bill is $25

They gave her $2 for the tip

if each got $1.00 back

Balance = $1.00 × 3

= $3.00

That means each paid $9×3 = $27 including $2 .00 tip(recall that cost of the meal is now $25 plus $2 tip)

Each of them got $1.00 back

Total money spent = (cost of meal + tip) + balance of $3.00 given to them

= $27 + $3

= $30

Therefore, there is no missing $1.00

A pan is heated to 393°F, then removed from the heat and allowed to cool in a kitchen where the room temperature is a constant 6
deff fn [24]

Answer:

The approximate temperature of the pan after it has been away from the heat for 9 minutes is 275.59°F.

Step-by-step explanation:

The formula for D, the difference in temperature between the pan and the room after t minutes is:

D = 324\cdot e^{-0.05t}

Compute the approximate difference in temperature between the pan and the room after 9 minutes as follows:

D = 324\cdot e^{-0.05t}

    =324\times e^{-0.05\times 9}\\\\=206.59

Then the approximate temperature of the pan after it has been away from the heat for 9 minutes is:

D = P - R

206.59 = P - 69

P = 206.59 + 69

P = 275.59°F

Thus, the approximate temperature of the pan after it has been away from the heat for 9 minutes is 275.59°F.

1)Find the angle of elevation of the sun from the ground when a tree that is
KIM [24]

Answer:

\theta=41.18^{\circ}

Step-by-step explanation:

Given that,

The height of the tree, h = 14 ft

The height of the shadow, b = 16 ft

We need to find the angle of elevation of the sun from the ground. Let the angle be θ. We can use trigonometry to find it. So,

\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{14}{16}\\\\\theta=41.18^{\circ}

So, the required angle of elevation of the sun is equal to 41.18^{\circ}.
