the amount is a positive "r", rate, thus is a growth equation, so it increased.
Answer:
1 cup of flour per 12 cookies
Step-by-step explanation:
2x=24y
divide by 2 on both sides
x=12y
Answer:
28.35
Step-by-step explanation:
Let cost of 1 coat = c.
Let cost of 1 umbrella = u.
7c + 12u = 399.45;
3c + 25u = 503.80
Multiply both sides of the first equation by 25.
Multiply both sides of the second equation by 12.
175c + 300u = 9986.25
36c + 300u = 6045.6
Subtract the second equation from the first equation eliminating u. Then solve for c.
139c = 3940.65
c = 28.35
Answer: A coat costs $28.35.

Respuesta:
21,16cm
Explicación paso a paso:
Volumen de un cono = 1 / 3πr²h
r es el radio de la base del cono
h es la altura del cono
Dados los siguientes valores
radio r = 18,8cm
Volumen = 416,4 centímetros cúbicos
Sustituir en la fórmula y obtener la altura.
Volumen de un cono = 1 / 3πrh
416,4 = 1 / 3π (18,8) h
416,4 = 1/3 * 3,14 * 18,8 h
416,4 = 19,6773h
Intercambio
19,6773h = 416,4
h = 416,4 / 19,6773
alto = 21,16 cm
<em>Por lo tanto, el valor más grande que se puede tomar para la altura h, por lo que el volumen es un máximo de 416,4 centímetros cúbicos es </em><u><em>21,16 cm.</em></u>
