Birds burgers barn sold 485 hamburgers today. The number sold with cheese wise half the number sold without cheese. How many of

frez [133]

Answer:

The number of hamburgers sold with cheese was 165 and the number of hamburgers sold without cheese was 330

Step-by-step explanation:

The correct question is

Birds burgers barn sold 495 hamburgers today. The number sold with cheese wise half the number sold without cheese. How many of each kind were sold?

Let

x -----> the number of hamburgers sold with cheese

y -----> the number of hamburgers sold without cheese

we know that

$x+y=495$ -----> equation A

$x=\frac{1}{2}y$ ----> equation B

substitute the equation B in equation A and solve for y

$y+\frac{1}{2}y=495$

$\frac{3}{2}y=495$

$y=495(2)/3$

$y=330$

Find the value of x

$x=\frac{1}{2}330=165$

therefore

The number of hamburgers sold with cheese was 165 and the number of hamburgers sold without cheese was 330

Determine whether or not f is a conservative vector field. if it is, find a function f such that f = ∇

olga nikolaevna [1]

F =del F, make the distinction its 2 different functions

in this case its a conservative vec field
u can do Del x F or curl F and see its not 0, but anyway, u can also integrate the portion in i wrt to x and portion in j component wrt to y, and see that even with the constants being functions of the variable not being integrated wrt to, you still cannot find a function g such that f(x,y)=del (g)
