Ao cobrar uma falta em um jogo de futebol, uma jogador imprime à bola a uma velocidade de 43,2 km/h. Sabendo que a bola gasta 3
Yakvenalex [24]

Answer:

B

Step-by-step explanation:

Nesta questão, estamos interessados ​​em calcular a distância percorrida se um jogador correr a uma velocidade de 43,2 km / h por 3 segundos.

Matematicamente; a distância percorrida = velocidade * tempo

O problema que temos aqui é que nossas unidades não são consistentes.

A melhor maneira de fazer isso é ter unidades consistentes em metros por segundos e segundos, pois nossa resposta está em metros.

Portanto, a conversão que precisamos fazer aqui é converter 43,2 km / h em metros por segundo Matematicamente, sabemos que existem 1000 m em um quilômetro.

Da mesma forma, uma vez que 60 segundos fazem um minuto e 60 minutos fazem uma hora, o número de segundos em uma hora é 60 * 60 = 3.600 segundos

Assim, convertendo 43,2 km / h em m / s, temos; (43,2 * 1000) / 3600 = 12 m / s

Portanto, a distância percorrida em metros seria agora; velocidade em m / s * tempo em segundos = 12 m / s * 3 segundos = 36 m

Inside the container there is empty space not taken up by the volleyball. What is the volume of that empty space? Use 3.14 for π
tensa zangetsu [6.8K]
Volume of Sphere is V=(4/3)*PI*r^3
The radius of the volleyball is 13 inches
So V=(4/3) * 3.14 * 13^3 =  9198 cubic inches
 
Volume of a cylinder is V=pi * r^2 *h
Since they say the ball fits perfectly
The radius is 13 and the height is 26 ( the diameter of the ball)
So V=3.14 * 13^2 * 26 = 13,797 cubic inches
 
13797 – 9198 = 4,599 cubic inches of empty space

I really hope this helps.

Is (-5,-8) a solution of y>3x+6
yuradex [85]

Answer:

yes

Step-by-step explanation:

To figure out if a point works with it's equation, you should replace the x and y with the point you got

-8 > 3(-5)+6

-8 > -15 +6

-8 > -9

Since -8 is bigger than -9, point (-5,-8) is true to the equation.

and as seen in the graph I have attached, the point does infact reside in the shaded in area. If you haven't learned how to graph this type of equation, you may disregard the graph :)

If you have any questions at all, don't be afraid to ask :)
