Given distance = speed x time How far would someone go if they drove 50 miles per hour for 30 minutes?​

Mathematics
1 answer:
omeli [17]4 years ago
4 0

Answer:

25 miles

Step-by-step explanation:

We need to convert 30 minutes to hours

30 minutes * 1 hour/ 60 minutes = .5 hours

distance = speed x time

distance = 50 mph * .5 hours

             = 25 miles

Mary Ellen invests $4000 in an account that earns 1.8% annual interest compounded monthly.
Vaselesa [24]

Answer:

22.5 years to the nearest tenth.

Step-by-step explanation:

The equation is

6000 = 4000(1 + 0.018/12)^12t     where t = the number of years

(1 + 0.018/12)^12t  = 1.5

1.0015^12t = 1.5

Taking logs:

12t log 1.0015 = log 1.5

12t = log 1.5 / log 1.0015

12t = 270.51

t = 22.54 years.

Please Help Me, This Is So Difficult.
Julli [10]

The maximum revenue would be $9600 and would be achieved using 0 nonstop flights and 12 two-stop flights.

<h3>How to define the variables</h3>

Let x = number of non-stop airplanes

Let y = number of two-stop airplanes

<h3>The system of linear inequalities</h3>

Using the variables in (a), we have the following constraints

Total passenger constraint: 150x + 100y <= 1500

Total Airplanes constraint: x + y <= 12

<h3>Graph the feasible region.</h3>

In (b), we have the following system of linear inequalities

150x + 100y <= 1200

x + y <= 12

See attachment for the graph

<h3>The objective function</h3>

The objective function of the constraints is:

Max z = 1100x + 800y

<h3>The maximum revenue</h3>

From the graph of the function, the optimal solution is:

(x,y) = (0,12)

So, the maximum revenue is:

z = 1100x + 800y

z = 1100*0 + 800*12

z = 9600

Hence, the maximum revenue is $9600

Find the amount and compound interest on 16000 for 2 years at 15%, interest being
Nat2105 [25]

Answer:

Step-bAmount at the end of 2 years = Rs. 21,160

Amount at the end of first year = Rs. 18,400

So interest for first year = Rs. 2400

Interest for second year = Rs. 2760

Explanation:

A = P (1 + r/n)^nt

P = 16,000

A = ?

r = 15% = 15/100

n= 1

t = 2

Substituting the values in the formula, we get:

A = 16000 (1 + 15 / 100) ^2

A = 16000 (23 / 20) ^2

A = 16000 * 23 * 23 / 400

A = 40 * 23 * 23

A = 21160

Amount at the end of 2 years = Rs. 21,160

Amount at the end of first year = Rs. 18,400

So interest for first year = Rs. 2400

Interest for second year = Rs. 2760
