Answer:

Option D. 20 minutes.

Step-by-step explanation:

It has been given in the question that distance between the shore of a lake is 3 miles.

Speed of Jim is 4 mph and speed of John is 5 mph.

Let they meet after time t hours.

Therefore distance traveled by Jim in t hours = 4×t miles

and distance traveled by John in t hours = 5×t miles

Total distance they cover = 3 miles.

Now 4t + 5t = 3

9t = 3

t = 3/9 hours.

t = (3×60)/9 minutes.

t = 20 minutes.

Answer is they will meet after 20 minutes.

Aurora hit a baseball with an initial velocity of 70 feet per second at an angle of 30° with the horizontal. The ball hit her ba
snow_tiger [21]

Answer:

See below

Step-by-step explanation:

Y component of velocity is 70 sin 30°

y position =   3  + 70 sin 30°  * t    - 1/2 a t^2

 when the ball hits the ground  y = 0

       0 = 3 + 70 sin 30°  t  - 1/2 (32.2)t^2

           - 16.1 t^2 + 35t + 3 = 0  

                    Use Quadratic Formula to find t = <u>2.26 seconds</u>

Horizontal component of initial velocity

 70 cos 30°             distance horizontal = 70 cos 30°  * t

                                   = 70 cos 30°  (2.26) =<u> 137.0 ft</u>

Kim is a medical supplies salesperson. Each month she receives a 5% commission on all her sales of medical supplies up to $20,00
lions [1.4K]

Answer: her sales for the month of May is $55000

Step-by-step explanation:

Let x represent her total sales for the month of May.

Each month she receives a 5% commission on all her sales of medical supplies up to $20,000. This means that for her first sales worth $20000, she earns a commission of

5/100 × 20000 = 1000

She also earns 8.5% on her total sales over $20,000. This means that for sales over $20000, she earns

8.5/100(x - 20000) = 0.085x - 1700

Her total commission for May was $3,975. The expression becomes

1000 + 0.085x - 1700 = 3975

0.085x = 3975 + 1700 - 1000

0.085x = 4675

x = 4675/0.085

x = 55000
