Brett has 2 1/2 pounds of bird seed left to share equally among 4 bird cages in his pet shop. How many pounds can he put in each
Ksju [112]

Answer:

Brett can put \frac{5}{8}  = 0.625 pounds in each bird cage.

Step-by-step explanation:

The total amount of bird seed left = 2\frac{1}{2} pounds

=\frac{5}{2} pounds

Number of birds in pet shop  = 4

So, the share of each bird = \frac{\textrm{Total available seeds}}{\textrm{Total number of birds in the pet shop}}

= \frac{\frac{5}{2} }{4}  = \frac{5}{2}  \times \frac{1}{4}  = \frac{5}{8}

Hence, Brett can put  \frac{5}{8}   = 0.625 pounds in each bird cage.

Jimmy drove to his cabin on the lake and back. it took 0.6 hours longer to go there than it did to come back. the average speed
Neporo4naja [7]
To answer this item, we let x be the distance that Jimmy drove from his origin and back. Given the speeds, the time it takes for him to travel to and fro are,
                                   t1 = x / 46
                                   t2 = x / 52
respectively.

The equation that would best represent the scenario is,
                              x/46 - x/52 = 0.6
The value of x from the equation is 239.2.

The trip there takes x/46 which is equal to 239.2/46 which is also equal to 5.2 hours. The travel from the cabin back took 4.6 hours.
