Responda:
3 horas
Explicação passo a passo:
Fração de hora gasta por sessão = 3/4 horas por sessão
Se o exercício for feito apenas aos domingos
Número de domingos por mês = 4
Portanto, número de sessões = 4
Fração de horas por sessão * Número de sessões
3/4 * 4 = 3 horas
Portanto, 3 horas são dedicadas ao exercício por mês
Answer:
B) x = 7, y = 4![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Step-by-step explanation:
you can find the value of 'y' first by connecting the bases with another altitute measuring 4 units
you now have an isosceles triangle where each leg is 4 which makes the hypotenuse equal to 4![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
to find 'x', it is the sum of 3 and 4
The expression can represent the value of x in terms of R, m, n and k after rearranging.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression is:
![\rm R = 4m\sqrt{\dfrac{xn}{k^3}}](https://tex.z-dn.net/?f=%5Crm%20R%20%3D%204m%5Csqrt%7B%5Cdfrac%7Bxn%7D%7Bk%5E3%7D%7D)
Square both side:
![\rm R^2 = 16m^2{\dfrac{xn}{k^3}}](https://tex.z-dn.net/?f=%5Crm%20R%5E2%20%3D%2016m%5E2%7B%5Cdfrac%7Bxn%7D%7Bk%5E3%7D%7D)
16m² x n = R²k³
x = (R²k³)/(16m²n)
The above expression represents the value of x in terms of R, m, n and k.
Thus, the expression can represent the value of x in terms of R, m, n and k after rearranging.

Answer:
-20
Step-by-step explanation:
P-17=2P+3
P-2P=17+3
-P=20
Divide both sides by negative 1
P=20
