1 answer:

ANSWER<em>.</em>

Aunque inicialmente un cohete despega verticalmente, para entrar en la orbita de la tierra debe inclinarse hacia un lado y gradualmente aumentar esa inclinacion hasta que logre una orbita eliptica alrededor de la tierra.

Por lo tanto un cohete debe curvar su trayectoria despues del lanzamineto si quiere entrar en la orbita de la tierra,si no hace eso con el tiempo su combustible se puede acabar y terminaria cayendo en la tierra.

Minchanka [31]

Answer:

$70\ \text{kilometers}$

Step-by-step explanation:

The scale of the map is 1 centimeter distance on the map represents 20 kilometers of actual distance.

The distance between the two cities is 3.5 centimeters on the map

$1\ \text{centimeters on the map}=20\ \text{kilometers of actual distance}$

So,

$3.5\times 20=70\ \text{kilometers}$

So, the distance between the two cities is $70\ \text{kilometers}$ .

Can somebody help me with the Math's questions on Pythagoras Theorem? Thanks

olga2289 [7]

Answer:

2.4 cans cost 47.4

If you cannot buy 2.4 cans, you must buy 3 cans, then you'll pay 59.25

Step-by-step explanation:

The lawn has trapezoidal shape, so find the area of the trapezoid using formula

$A=\text{Midline}\times \text{Height}$

In the diagram, ABED is rectangle, so BE = 12 m, thus ED = 20 m - 12 m = 8 m.

Consider right triangle EDC. By the Pythagorean theorem,

$ED^2+EC^2=CD^2\\ \\ED^2+8^2=17^2\\ \\ED^2=289-64\\ \\ED^2=225\\ \\ED=15\ m$

Thue,

Height = 15 m

Find the midline:

$\text{Midline}=\dfrac{AD+BC}{2}=\dfrac{12+20}{2}=16\ m$

Hence,

$A=16\cdot 15=240\ m^2$

One can cover $100\ m^2,$ to cover $240\ m^2$ is needed

$240:100=2.4$ cans

One can costs 19.75, so 2.4 cans cost

$19.75\cdot 2.4=47.4$

If you cannot buy 2.4 cans, you must buy 3 cans, then you'll pay

$19.75\cdot 3=59.25$
