Mr.Hall stands 200 meters from the base of the water tower. He finds the angle of elevation to the top of the water to be 27 deg

love history [14]

Height of the tower = 101.9 m

Solution:

Given data:

Angle θ = 27°

Adjacent side = 200 m

Opposite side = Height

Let height be taken as h.

The given image shows it is a right triangle.

Using basic trigonometric ratio formulas,

$$\tan \theta=\frac{\text { Opposite side of } \theta}{\text { Adjacent side of } \theta}$

$$\tan27^\circ =\frac{{ h}}{200}$

The value of tan 27° = 0.5095

$$0.5095 =\frac{{ h}}{200}$

Do cross multiplication, we get

0.5095 × 200 = h

101.9 = h

Height of the tower = 101.9 m

Answer:

(B) $477=6(1+0.20)^t$

Step-by-step explanation:

we can use formula

$P(t)=P_0(1+r)^t$

where

Po is the initial population

r is the growth rate

t is the time in months

We are given

initial population of insects

so, Po=6

The scientists find that the insect population, x, is growing exponentially 20% per month

so, r=0.20

now, we can plug these values

$P(t)=6(1+0.20)^t$

there to be a population of 477 insects

so, P(t)=477

now, we plug it

and we get

$477=6(1+0.20)^t$

TEA [102]

Answer:

El área a cubrir es de 4800 cm^2.

Step-by-step explanation:

<em>La pregunta está incompleta:</em>

<em>Laura quiere cubrir con papel de china una puerta como la que se muestra en el dibujo cuánto es centímetros cuadrados. Las medidas son 80 cm de largo y 60 cm de ancho.</em>

Tenemos que calcular el área que representa la puerta, cuyos lados son 80 cm y 60 cm.

El área A se calcula multiplicando ambos lados:

$A=80\,cm\cdot60\,cm=4800\,cm^2$
