Let
F = number of flashlights at $12 each
B = number of sleeping bags at $45 each.
F = 5B "The number of flashlight (F) ordered was five times the number of sleeping bags (5B)."
($12)F + ($45)B = $1785 "...the total cost was $1785,..." Substitute F = 5B.
12(5B)+45B = 1785 Simplify and solve for B.
60B+45B = 1785

105B = 1785 Divide both sides by 105.
B = 17 and...
F = 5B
F = 5(17)
F = 85
17 sleeping bags and 85 flashlights were ordered.

Answer:

216.66 yd²

Step-by-step explanation:

One way to find the area of a ring like this is to multiply its centerline length by the width of the ring.

Here, the diameter of the circle that is the centerline of the ring is 23 yd. The circumference of that circle is ...

C = πd = 3.14(23 yd) = 72.22 yd

Then the ring area is ...

(72.22 yd)(3 yd) = 216.66 yd² . . . area of shaded region

Use the "mixed partials" check to see if the following differential equation is exact. If it is exact find a function F(x,y) who

Arturiano [62]

We have

$(-3xy^2+y)_y=--6xy+1$

and

$(-3x^2y+x)_x=-6xy+1$

so the equation is indeed exact. So we want to find a function $F(x,y)=C$ such that

$F_x=-3xy^2+y$

$F_y=-3x^2y+x$

Integrating both sides of the first equation wrt $x$ gives

$F(x,y)=-\dfrac32x^2y^2+xy+f(y)$

Differentiating both sides wrt $y$ gives

$F_y=-3x^2y+x=-3x^2y+x+f_y\implies f_y=0\implies f(y)=C$

So we have

$F(x,y)=-\dfrac32x^2y^2+xy+C=C$

$F(x,y)=\boxed{-\dfrac32x^2y^2+xy=C}$

Answer:

(6 - 2) / 3

Step-by-step explanation:
