Are the ratios 2:1 and 19:10 equivalent?
Oduvanchick [21]

Answer:

No.

Step-by-step explanation:

2:1 and 19:10 are not equivalent.

Simply, because if you divide 9 by any number with the 10, it is not going to stay as a whole number. For example, 19 divided by 2 equals 9.5. 19 divided by 5 equals 3.8. So, no they are not equivalent.

Two numbers (represented by A and B) when multiplied together produce a maximum value. Two times the first number (A) plus one t
marusya05 [52]

Maximize U=ab subject to 2a+b=48

b = 48-2a

U = ab = a(48-2a)

U = -2(a^2 - 24 a) =-2(a^2 - 24 a + 144) + 2(144) = -2(a-12)^2+288

That's clearly maximum when the squared term is zero, so

a=12

b=48-2(12) = 24

U=12(24)=288

Answer: a=12, b=24, max 288
