Fabio and Gwen are saving money to buy a new gaming station. They need at least $510 to purchase the new gaming station. Gwen we

Phoenix [80]

Answer-

Set of constraints to model the problem are,

$12x+9y\geq 510$

$y \leq 2x$

$y \geq 25$

Solution-

x = the number of lawns weeded by Gwen,

y = the number of dogs walked by Fabio.

As, Gwen charges $12 each time she weeds a yard and Fabio charges $9 each time he walks a dog,

$\text{Earnings of Gwen} = 12x$

$\text{Earnings of Fabio} = 9y$

$\text{Total earning} = 12x+9y$

They need at least $510 to purchase the new gaming station, means they need $510 or more than $510.

The equation for this is,

$12x+9y\geq 510$

The number of dog walks that Fabio has scheduled is no more than twice the number of yards Gwen has scheduled to weed, means

y must be less than or equal to 2x.

The equation for this is,

$y \leq 2x$

Fabio will walk at least 25 dogs, means y must be greater than of equal to 25.

The equation for this is,

$y \geq 25$

Ferris wheel has a diameter of 60 ft. How far will a rider travel during a 5 minute ride if the wheel rotates once every 15 seco

Neporo4naja [7]

Answer:

3769.92 ft

Step-by-step explanation:

The diameter of the wheel, d= 60 ft

We know the perimeter of the wheel is,

= πd

= 3.1416*60

= 188.496 ft

Wheel travel for 5 minutes. So the wheel travel,

= 5*60

= 300 sec

The wheel rotates in every 15 seconds. So the wheel rotates,

= 300/15

= 20 times

In one rotation, the wheel travels its perimeter. so is 5 minutes it travels,

= 188.496*20

= 3769.92 ft

PLEASE HELP!! ASAP!!

mr Goodwill [35]

Answer:

D and E

Step-by-step explanation:

A vertical asymptote in this case would mean that the denominator is equal to zero, which is undefined. You can factor the denominator to get you the fraction:

x+2 / (x+6)(x-4) = 0

Then you know that to equal zero, x would have to equal either -6 or 4, which is E and D.
