6 students have black hair, 3 students have blonde hair, and 21 students have brown hair. since percentages come out of 100% you can use ten as a smaller size, so 20% of 10 is 1, multiply that by three because our full percentage is out of 30, and you get 3, and so on.

Uma volta inteira na Terra corresponde a uma distância 2πr≅40.000 km. Se um satélite leva 85 minutos para dar uma volta completa

Shalnov [3]

Answer:

7.8. 10 ^ 3 m / s

Step-by-step explanation:

The computation of the average speed in m/s is shown below:

The average speed equation is

= ΔS ÷ Δt;

As We know that

an entire revolution would be40,000 km

and a satellite takes 85 minutes to complete a revolution,

So,

ΔS = 40,000 km = 40,000,000 m

Δt = 85 min = 5 100 s

Now the average speed is

= 40 000 000 ÷ 5 ÷ 5 100

= 7843.14 m / s

= 7.8. 10 ^ 3 m / s

Find the inverse of the function f(x) = 4x – 2.<br>Then graph the function and its inverse.<br>

NemiM [27]

Answer:

Y = 1/4x + 1/2

Step-by-step explanation:

The inverse is found by reflecting the graph across the y=x line. In the equation, this result by switching x and y then solving for y.

Y =4x-2

X=4y-2

X+2=4y

(X+2)/4= y

1/4x +1/2 =y
