Translate into an algebraic expression and simplify if possible. C It would take Maya x minutes to rake the leaves and Carla y m
lawyer [12517]

Answer:

together they rake \frac{y+x}{xy} leaves in one minute.

Step-by-step explanation:

If Maya takes x minutes to rake, then in one minute, she rakes \frac{1}{x} leaves.

For Carla, if her raking takes y minutes, in one minute she rakes \frac{1}{y} leaves.

Thus, to find the amount they work together in one minute, we add both of their contributions for that minute, resulting in: \frac{1}{x}+ \frac{1}{y}

Finally, simplifying this expression gives:

\frac{1}{x}+ \frac{1}{y} =\frac{y+x}{xy}

As a result, they collectively rake \frac{y+x}{xy} leaves in a minute.

If t represent the number of tickets purchased for a baseball game, which scenario is modeled by the equation, 32.50t + 5 = 28.7
tester [12383]

Answer: By substituting t with 4, we find that 32.5*4 + 5 yields 135 and 28.75 * 4 + 20 results in the same value of 135, confirming the equation is valid.

or

By using 4 as the value for t in the equation, a true statement emerges, indicating that the Burns family will incur a cost of $135 for 4 tickets and parking regardless of whether the choice is lower-level or middle-level seating.

Consider the following differential equation. (A computer algebra system is recommended.) (1 + t2)y' + 4ty = (1 + t2)−2 (a) Draw
PIT_PIT [12445]

Answer:

Step-by-step explanation:

a. Create a direction field for the specified differential equation

b. By observing the direction field, comment on the behavior of the solutions as t becomes large.

The solutions seem to oscillate

All solutions appear to approach the function y0(t)=4

All solutions seem to converge to the function y0(t)=0

All solutions appear to have negative slopes eventually and thus decrease indefinitely

All solutions seem to have positive slopes eventually and therefore increase without limit

C

As t approaches infinity

All solutions seem to exhibit positive slopes eventually and thus decrease indefinitely

The solutions seem to gradually approach the function y0(t)=0

All solutions appear to eventually have negative slopes leading to decrease without bounds

All solutions seem to converge to the function y0(t)=4

The results are oscillatory

A law firm is going to designate associates and partners to a big new case. The daily rate charged to the client for each associ
babunello [11817]

Response:

Each associate incurs a cost of $700 daily for the client, meaning that 'a' associates will cost the client 700a dollars each day. For each partner, the charge is $1500 daily, so 'p' partners will accumulate a cost of 1500p dollars daily. The cumulative bill amounts to 700a + 1500p = $14100:

700a + 1500p = 14100

700a + 1500p = 14100

Given that there are a total of 11 lawyers assigned (associates and partners), the equation a + p must equal 11.

a + p = 11

a + p = 11

\underline{\text{Formulate System of Equations:}}

Formulate System of Equations:

​

700a + 1500p =

700a + 1500p = 14100

14100

a + p = 11
