Magda saw a triangular sign with a base of 4 feet and a height of 2.8 feet. She reasoned that if she first divided each dimensio

motikmotik

Answer: She is not correct, because she must multiply the base and the height of the triangle and then divide by 2.

Step-by-step explanation:

1. The formula for calculate the area of a triangle is shown below:

$A=\frac{b*h}{2}$

Where $b$ is the base and $h$ is the height.

2. Then, if she applied the method she reasoned, she'd obtain the following area:

$b=\frac{4ft}{2}=2ft\\h=\frac{2.8ft}{2}=1.4ft\\A=2ft*1.4ft\\A=2.8ft^{2}$

3. But actually, Magda should multiply the base and the height of the triangle and then divide by 2. Then, the correct area is:

$A=\frac{4ft*2.8ft}{2}=5.6ft^{2}$

While moving up on the rope-way, I noticed that the seat place in the opposite direction was numbered as 95. Behind it was numbe

Verizon [17]

The seat in the middle of the one-way route is 34

The seats are given as:

$First= 0$ --- the first seat behind the seat number 95

$Last= 66$ --- my seat

The seat number half-way would be:

$Half = \frac{Last - First}{2} + 1$

This gives

$Half = \frac{66- 0}{2} + 1$

Subtract 0 from 66

$Half = \frac{66}{2} + 1$

Divide 66 by 2

$Half = 33 + 1$

Add 33 and 1

$Half = 34$

Hence, the seat in the middle of the one-way route is 34
