Marta leyó 1,625 veces la cantidad de páginas leída por su hermano.

En esta pregunta debemos determinar la razón (r) de la cantidad de páginas <em>leída</em> por Marta (x) a la cantidad de páginas <em>leída</em> por su hermano (y). Es decir,

r = \frac{x}{y} (1)

Si sabemos que x = 52 y y = 32, entonces la razón definida al principio de esta respuesta es:

r = \frac{52}{32}

r = 1,625

Marta leyó 1,625 veces la cantidad de páginas leída por su hermano.

Answer:

Let F = Fran's income

Let W = Winston's income

Combined income is 80000  ==>  F + W = 80000

One quarter of Winston's income is the same as one-sixth of Fran's income  ==>  

(1/4)*W = (1/6)*F

Multiply the 2nd equation by 12 to clear the fractions  

3*W = 2*F

Solve this equation for F

F = (3/2)*W

Substitute this value for F into the 1st equation

(3/2)*W + W = 80000

(5/2)*W = 80000

W = (2/5)*80000 = 32000

So F = 80000 - 32000 = 48000

So Winston earns 32000 and Fran earns 48000

Check:  One quarter of Winston's income is 32000/4 = 8000

           One sixth of Fran'e income is 48000/6 = 8000

Step-by-step explanation: Hope this helps

notka56 [123]

Answer:

x = 4

Step-by-step explanation:

11x= 6x +20

-6x   -6x

(subtract 6x from both sides)

5x = 20

/5x   /5x

divide 5x from both sides

x=4

Angle AOC = 46°   Find angle BPO

We have congruent right triangles PAO and PBO, right angles A and B.

So AOC=BOC=46 degrees,

PBO is a right angle so BPO is complementary to BOC, so 42 degrees

Answer: 42 degrees
