A class is organizing a going away party for one of their students. They spend $26.38 on decorations, $78.92 on food, and $34.50

Serjik [45]

Answer:

$9.35

Step-by-step explanation:

Simply start by adding up the total cost of each item.

$26.38 + $78.92 + $34.50

= $140.25

The total is $140.25

If 15 students want to split the cost, you’ll need to divide it by 15.

$140.25 divided by 15 = $9.35

So the total for each student is $9.35

John stands 150 meters from a water tower and sights the top at an angle of elevation of 36º. If John's eyes are 2 meters above

horsena [70]

Answer:

The height of tower $DB=111\ meters$ .

Step-by-step explanation:

Diagram of the given scenario is shown below.

Given that,

Distance between John and tower is $CE=150 \ meters$ .

Angle of elevation to the top of the tower is $\angle DEC=36$ °.

Height of John is $CB=2\ meters$ .

To Find: Height of the tower $DB$ .

So,

In triangle ΔDCE,

$Tan$ (∠ $DEC)= \frac{DC}{CE}$

$Tan (36)= \frac{DC}{150}$

$DC= tan(36)\times 150$

$DC=108.98\ meters$

Now,

To calculate the height of tower we have

$DB=DC+CB$

$DB=108.98+2$

$DB=110.98\ meters$ ≈ $111 \ meters$

Therefore,

The height of tower $DB=111\ meters$ .
