A cylinder is full at 471 cubic centimeters and has a radius of 5 centimeters. it currently contains 314 centimeters of water.
what is the difference between the height of the water in the full cylinder and the height when 314 cubic centimeters of water remains in the cylinder?
use 3.14 for pi
310 cm
Answer:
y=-4/7
Step-by-step explanation:
7y/2=-2
multiply both sides by 2
7y=-4
divide both sides by 7
y=-4/7
Answer:
2.45
Step-by-step explanation:
Answer:
72, 216 , 252
Step-by-step explanation:
Deje que lo que ella leyó inicialmente sea x páginas.
La segunda semana leyó 3 veces esto = 3 * x = 3x.
La tercera semana leyó 5 veces la primera semana menos 108 = 5x-108.
Así que agreguemos todos juntos para obtener x. 3x + x + 5x-108 = 540.
9x = 540 + 108 9x = 648 x = 648/9 = 72 páginas.
Leyó 72 páginas la primera semana.
Ella leyó 3 * 72 en la segunda semana = 216 páginas En la tercera semana leyó 5 (72) -108 = 360-108 = 252 páginas
Answer:
Answer choice a.
Step-by-step explanation:
Let's do part of the work of solving the given system:
6x + 2y = −6
3x − 4y = −18
Multiply the first equation by 2 so as to make the coefficient of y = to 4:
12x + 4y = -12
Combine this result with the second equation:
12x + 4y = -12
3x − 4y = −18
------------------------
15x = -30
Note that these results are precisely the same as the equations in Answer Choice a.
