Answer 1

Answer:

Answer:

1. The slant height of the tower of Pisa is $√(H_v^2 + L_s^2)$

Where:

$H_v$ = Vertical height of the tower of Pisa (Required)

$L_s$ = Length of from the base of the tower to the point where the top is directly up above

2. Calculation of time using the length our shadow

Step-by-step explanation:

1) As the sun is rising, we measure the our shadow and the measure the shadow cast by the leaning side of the tower of Pisa, then we use similar triangles to calculate the vertical height of the tower of Pisa as follows;

$(Our \, Height \, (known))/(Length \, of \, our \, shadow \, (known)) = ( Vertical \, height \, of \, the \, tower \, of \, Pisa \, (Required) \, H_v)/(Length \, of \, the \, shadow \, cast \, by \, the \, slant \, side \, of \, the \, tower \, of \, Pisa, \ L_V)$

$Vertical \, height \, of \, the \, tower \, of \, Pisa \, (Required) \, H_v} = (Our \, Height \, (known) * L_v)/(Length \, of \, our \, shadow \, (known))$

Then, at exactly noon, or when the Sun is directly overhead the tower casting a shadow, we measure the length of the covering from the the base to end of the shadow where the tip is directly up ahead (which can be done by measuring the base of the tower to the point where the top of the tower is directly up above), we call this length $L_s$

Then, the slant height of the tower of Pisa = $√(H_v^2 + L_s^2)$

2. Other real world situation is the calculation of the time of the day using our shadow and triangulation.

Answer:

w = 21

x = 13

y = -11

z = -16

Step-by-step explanation:

Matrix subtraction is simply subtracting "corresponding" values e.g. row 1 column 1 value of one matrix and row 1 column 1 value of another matrix, and so on...

Thus, w = 17 - (-4) = 17 + 4 = 21

x = 12 - (-1) = 12 + 1 = 13

y = -3 -8 = -11

z = -2 -14 = -16

These are the values of w, x, y and z , respectively.

For a field trip, 56 students registered. On the day of the field trip, 7 students were unable to go. Which decimal describes the ratio of students who were unable to go to the number of students who registered for the field trip?

Solutions

For a field trip, 56 students registered. On the day of the field trip, 7 students were unable to go.

We know that 7/56 could not go therefore 7 ÷ 56 = .125 or round to .13 could not go.

7/56 = .125 or round to .13
