1/2 of the people in the clinic are men, 1/3 are elderly, how many people are not elderly or men?
Nostrana [21]

1/6 of the people are not elderly or men

<h3>How to determine the proportion?</h3>

The given parameters are:

Men = 1/2

Elderly = 1/3

The number of people that are not elderly or men are:

People = 1 - Men - Elderly

So, we have:

People = 1 - 1/2 - 1/3

Evaluate

People = 1/6

Hence, 1/6 of the people are not elderly or men

ki77a [65]

Answer:

3 unidades de comprimento

Step-by-step explanation:

O perímetro é definido como a soma de todos os lados.

O perímetro de um quadrado de lado 2x é dado por:

Q=4*2x=8x

O perímetro de um retângulo de comprimento x e largura x² é dado por:

R=2x+2x^2

Para que ambos os perímetros sejam iguais:

R=Q\\8x=2x+2x^2\\x^2=\frac{6}{2}x\\ x=3

O valor de x é igual a 3 unidades de comprimento.

(5/10) find an implicit expression of all solutions y of the differential equation above, in the form \psi(t,y) = c, where c col
Thepotemich [5.8K]

solution:

Consider the differential equation,

7ty + (1+t2)1/2y1 = 0

Rewrite the DE as,

(1+t2)1/2dy = - 7ty

dy/y = -7t/√1+t2 dt

in y = -7(1+t2) + c

y = ce-7(1+t2)

given,

y(0) = 1 => ce-7 = -1 => c = e7

ᴪ (t,y) = y -ce ᴪ(0,1)(1+t2)
