The distance to the moon is approximately 240,000 miles. This can be expressed as 2.4 multiplied by 10 raised to the power of 5.
Respuesta:
la cantidad de elemento restante después de 14 minutos = 7.091 g =~ 10 g
Explicación paso a paso:
Después de cada minuto, la cantidad que queda será
(100 - 26.9) % es decir, 73.1 %
lo que equivale a 0.731 veces la cantidad inicial.
Si el tiempo transcurrido se representa como t, la función f(t) indica la masa del elemento restante, nuestra ecuación será
f(t) = 570(0.731) ^ t
t= 14 minutos
f(14) = 570 (0.731) ^ 14
= 7.091 g =~ 10 g
Answer:
D
Step-by-step explanation:
it represents entire F as shown in the diagram
(2 6/7) divided by (1 2/3) equals x over 1.
Cross-multiply and convert mixed numbers to improper fractions:
(5/3)x = 20/7
Solving for x:
x = (20/7) × (3/5)
x = 60/35, which simplifies to 1 5/7 songs per minute.
Answer:
A is TRUE (44 in² * 2 = 88 in²).
B is FALSE because x(x-3) = 88 for the rectangle or x(x-3)/2 = 44 for the triangle.
C is TRUE if x(x-3) = 88 leads to x² - 3x - 88 = 0.
D is TRUE:
x² - 3x - 88 = 0.
Δ = 9 + 4 * 88 = 361 = 19².
Thus, x = 11 or x = -8 (we discard negative values).
E is FALSE as 11 * 4 ≠ 88.
