Problemas de razonamiento división de números decimales. Ayer Susana se fue de viaje a visitar a unos familiares. Recorrió 135,7

schepotkina [342]

Usando las relaciones entre velocidad, distancia y tiempo, se encuentra que ella condujo a una velocidad media de 90,5 km/h.

--------------------------

La velocidad es la distancia dividida por el tiempo, por lo que:

$v = \frac{d}{t}$

Total de 135,75 km, o sea, $d = 135,75$
Llego en 1,5 horas, o sea, $t = 1,5$

La velocidad es:

$v = \frac{d}{t} = \frac{135,75}{1,5}$

División de decimales, o sea, seguimos multiplicando los números por 10 hasta que ninguno sea decimal:

$v = \frac{135,75}{1,5} = \frac{1357,5}{15} = \frac{13575}{150} = 90,5$

Ella condujo a una velocidad media de 90,5 km/h.

PLEASE HELPP PRE CAL!!

Snezhnost [94]

Step-by-step explanation:

tan x = 3/4

Tangent is opposite over adjacent, so draw a right triangle with angle x where the opposite side is 3 and the adjacent side is 4.

Use Pythagorean theorem to find the hypotenuse:

c² = 3² + 4²

c² = 25

c = 5

Sine is opposite over hypotenuse, so:

sin x = 3/5

Factor completely B. (x+5)²-2(x+5)-24 C. (x+2)²-8(x+2)+15 D. 2(2x-1)²-9(2x-1)+4

Sladkaya [172]

B.
${x}^{2} + 10x + 25 - 2x - 10 - 24 = \\ x {}^{2} + 8x - 9 = \\ (x - 1)(x + 9)$

C.
${x}^{2} + 4x +4 - 8x - 16 + 15 = \\ x {}^{2} - 4x + 3 = \\ (x - 3)(x - 1)$
D.
$2( {4x}^{2} - 4x + 1) - 18x + 9 + 4 = \\ 8x {}^{2} - 8x + 2 - 18x + 13 = \\ 8x {}^{2} - 26x + 15$

There are 16 students playing kickball. Two students leave to go play hopscotch. How do you write the fraction of children left

olga55 [171]

Answer:

7/8

Step-by-step explanation:

When 16 students are playing kickball, there are 16/16 students on the field. After 2 leave, this becomes 16-2/16, therefore 14/16 which is divisible by 2. and therefore 7/8, which the numerator and denominator have no common divisors.
