. Los satélites del proyecto Starlink, de Elon Musk, giran con rapidez angular constante alrededor de la Tierra. Realizan una órbita completa en 90 minutos a una altura promedio de 300 km de altura sobre la superficie
terrestre (por tanto, el radio de la órbita es de aproximadamente 6670 km, medido desde el centro de la tierra).
a) Calcula la rapidez angular en rad/s, de los satélites.
b) Calcula su rapidez lineal en rad/s, de los satélites.

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
