Answer:
Nuestra masa ejerce una fuerza de 931,665 newtons por efecto de la gravedad terrestre.
Step-by-step explanation:
Nuestro peso puede determinarse mediante la definición de peso (
), medido en newtons, representado por la siguiente fórmula:
(1)
Where:
- Masa, medida en kilogramos.
- Aceleración gravitacional, medida en metros por segundo cuadrado.
Si sabemos que 
y 
, entonces la fuerza que ejerce sobre nuestra masa es:
Nuestra masa ejerce una fuerza de 931,665 newtons por efecto de la gravedad terrestre.
49, because if he bought 9 you need to add that to 40 to get the whole
Answer:
15
Step-by-step explanation:
Let n, d, q represent the numbers of nickels, dimes, and quarters. The problem statement tells us ...
n +d +q = 37
n = d +4
q = n +2
___
Rearranging the second equation gives ...
d = n -4
Substituting that into the first, we get ...
n + (n -4) +q = 37
2n +q = 41 . . . . . . . add 4 and simplify
Rearranging the third original equation gives ...
n = q -2
Substituting into the equation we just made, we get ...
2(q -2) +q = 41
3q = 45 . . . . . . . . add 4 and simplify
q = 15 . . . . . . . . . divide by 3
Joe has 15 quarters.
_____
<em>Check</em>
The number of nickels is 2 fewer, so is 13. The number of dimes is 4 fewer than that, so is 9. The total number of coins is 15 + 13 + 9 = 37, as required.
<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>Let's find 'a' using Pythagoras theorem.</u>
- => 4² = 2² + a²
- => 16 = 4 + a²
- => 12 = a²
- => a = √12
- => a = √2 x 2 x 3
- => a = 2√3
- => a = 2 x √3
- => a = 2 x 1.732
- => a = 3.464 = 3.5 (Estimated)
