Answer:
The increment in the model is 106cm
Step-by-step explanation:
Given
[tex]Initial\ Height = 53cm[/tex]
[tex]Final\ Height = 159cm[/tex]
Required
Determine the increment
To do this, we simply subtract the initial height of the building from the final height
[tex]Increment = Final\ Height - Initial\ Height[/tex]
[tex]Increment = 159cm - 53cm[/tex]
[tex]Increment = 106cm[/tex]
Hence, the increment in the model is 106cm

Un marino está parado en la proa de un velero y observa el faro en la orilla de la costa.Si el marino tiene una estatura de 1.80m y proyecta una sombra de 2m de largo sobre el velero,¿a que distancia se encuentra este hombre de la costa si se sabe que la altura del faro respecto al nivel Del Mar es de 36m?
Answer:
El marino se encuentra a 40 metros de la costa.
Step-by-step explanation:
Podemos ver la conjunción de la proyección de la sombra del marino con su altura como un triángulo rectángulo con:
b: base = cateto inferior = 2 m
h: altura = cateto superior = 1.80 m
θ₁: ángulo entre la hipotenusa y h (cateto inferior o base).
De este primer triángulo tenemos:
[tex] tan(\theta_{1}) = \frac{h}{b} = \frac{1.80 m}{2 m} = 0.9 [/tex] (1)
Ahora, dado que la proyección del marino se debe al faro, de la atura de éste junto con la distancia entre el marino y la costa tenemos:
x: distancia entre el marino y la costa = cateto inferior =?
H: altura del faro = cateto superior = 36 m
θ₂: ángulo entre la hipotenusa y "x" (base).
De este segundo triangulo tenemos:
[tex] tan(\theta_{2}) = \frac{H}{x} = \frac{36 m}{x} [/tex]
[tex]x = \frac{36 m}{tan(\theta_{2})}[/tex] (2)
Debido a que θ₁ = θ₂ (por ser los dos triangulos semejantes), entonces introduciendo la ecuación (1) en (2) tenemos:
[tex]x = \frac{36 m}{tan(\theta_{1})} = \frac{36 m}{0.9} = 40 m[/tex]
Por lo tanto, el marino se encuentra a 40 metros de la costa.

One pipe can fill a tank in 24 minutes, a second can fill it in 8 minutes, and a third can fill it in 12 minutes. If the tank is empty, how long will the three pipes, operating together, take to fill it?
4 4/5 minutes
4 minutes
1/6 minute
Answer:
4 mins
Step-by-step explanation:
Tank 1: 24
Tank 2: 8
Tanks 3: 12
So you add them all up to equal the "work". which is one. Looks like this:
*** x/24 + x/8 + x/12 = 1 ***
multiply all by 24
x+3x+2x=24
add like terms
6x=24
divided by 6
x=4
So x=4 minutes.

You must scuba dive to the entrance of your room at Jules' Undersea Lodge in Key Largo, Florida. The diver is 1 foot deeper than 2/3 of the elevation of the entrance. The diver is -15 feet in the water. What is the elevation of the entrance?
Answer:
The answer is -21
Step-by-step explanation:
The elevation of the entrance of your room at Jules' Undersea Lodge is equal to -21 feet.
What do you mean by algebraic expressions ?
Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.
It is given that , diver is 1 foot deeper than 2/3 of the elevation of the entrance. And the depth of diver is equal to -15 feet.
So , the diver is at depth under water = -15 feet
Let's assume that elevation of entrance is at x foot.
So , the algebraic expression representing the depth of diver is given by :
[tex]\frac{2}{3}[/tex] × x - 1 = -15
Solving for the value of x or the elevation of entrance we get :
[tex]\frac{2}{3}[/tex] x = -15 + 1
[tex]\frac{2}{3}[/tex] x = -14
2x = -14 × 3
x = -42 / 2
x = -21 feet
Thus , the elevation of the entrance of your room at Jules' Undersea Lodge is equal to -21 feet.

Marg earns $13.10 an hour and works 40 regular hours and 8 hours of overtime in one week. If she is paid time and a half for overtime, what is her gross pay for the week?
Answer:
Her gross pay for the week is $681.2.
Step-by-step explanation:
First, you can determine the amount she would earn for working 40 regular hours by multiplying the number of hours for the amount she receives per hour:
$13.10*40=$524
Now, to calculate the amount Marg earns for 8 hours of overtime, you need to determine the amount she earns per hour of overtime given that she is paid time and a half which means that you need to multiply the amount she earns by regular hour for 1.5. Then, you have to multiply this for the number of hours:
($13.10*1.5)*8=$157.2
Finally, you need to add the amount she earns by working 40 regular hours plus the amount she earns by working 8 hours of overtime in one week:
$524+$157.2=$681.2
According to this, the answer is that her gross pay for the week is $681.2.

b) What is the wavelength of the waves? 5 pts
c) How many waves are generated in two seconds? 10 pts
d) What is the frequency of the waves? 10 pts
e) What is the period of the wave? 10 pts
Answer:
a) 0.4m
b)2m
c)2
d)1 s^-1
e) 1 s
Step-by-step explanation:
a) The amplitude of the wave is the highest vertical displacement
with respect to this question, this is 0.4m
b) The wavelength of the wave is simply the distance between two crest or troughs
In this question, this is 2m
c) The number of waves generated is 2
d) Frequency of the waves is the number of waves generated per second
if 2 waves are generated in 2 seconds
The number of waves in a second is 2/2 = 1
So the frequency is 1 s^-1
e) Period is 1/frequency
= 1/1 = 1 second
