You would need to know the cost of the box of 20, then you would divide the total cost by the number of pencils in the box. This would give you the cost of one pencil - which is the unit cost.


Example:

Lets say the box of 20 pencils cost $10.


Divide the total cost by the number of pencils:

10 / 20 = 0.50 - This means each pencil cost 50 cents, so the unit cost would be 50 cents per pencil.

muminat

Answer:32.1428571429 feet

Step-by-step explanation:

The flag is 15 feet.

It's shadow is 10.5 feet.

15/10.5=1.4285714286.

So the flag is above mentioned times of the shadow.

And the tree's hight will be,

22.5*1.4285714286

=32.1428571429 feet.

Question 1
Vikki [24]

Answer:

(B)15,36,39

Step-by-step explanation:

To determine which of the line segments could create a Right Triangle, we check if it satisfies the Pythagoras Theorem, taking the longest part to be the Hypotenuse in all cases.

By Pythagoras Theorem: Hypotenuse^2=Opposite^2+Adjacent^2

In  15,30,35

35^2\neq 15^2+30^2\\1225\neq 1125

In 15,36,39

39^2=36^2+15^2\\1521=1521

In 15, 20, 29

29^2\neq 15^2+20^2\\841\neq 625

In 5,15,30

30^2\neq 15^2+5^2\\900\neq 250

We can see that only 15,36,39 satisfies the required condition and thus it could be used to create a right triangle.
