PLEASE, IT IS URGENT!!!!!!!!!!!!!!!!

Convert the timing into hours only:
11:15  = 11.25h
 9:45  = 9.75h
11:45 = 11.75h
 7:45  = 7.75h
10:45 = 10.75h

To find the average, we need to find the middle of these timing:
11.25 + 9.75 + 11.75 + 7.75 + 10.75 = 51.25

51.25 ÷ 5 = 10.25h = 10:15 am

------------------------------------------------------------------------
Answer: The average time it docks is 10:15 am.

Interest earned:$45 Principal: ? Interest rate: 3% Time: 2 years
Yakvenalex [24]

Answer:

The Principal = $75,000

Step-by-step explanation:

Formula for finding the principal:

I × 100/ R × T

Therefore;

Principal = 45 × 100 / 3/ 100 × 2

=  \:  \frac{45 \times 100}{ \frac{3}{100}  \times 2}  \\  =  \frac{4500}{ \frac{3}{50} } \\  = 4500 \times  \frac{50}{3}  \\  = 1500 \times 50 \\  = 75000.00

Which means that the Principal is $75,000.00

Find the break - even points for company X, which sells all it produces, if the variable cost per unit is $3, fixed costs are $2
ohaa [14]

Given:

The variable cost per unit is $3, fixed costs are $2.

The revenue function is:

Y_{TR}=5\sqrt{q}

where q is the number of thousands of units of output produced.

To find:

The break - even points for company X.

Solution:

The variable cost per unit is $3, fixed costs are $2.

So, the cost function is:

Total cost = Fixed cost + Variable cost × Quantity

Y_{TC}=2+3q

The revenue function is:

Y_{TR}=5\sqrt{q}

At break - even points the profit is zero. It means the cost and revenue are equal.

Y_{TC}=Y_{TR}

2+3q=5\sqrt{q}

Squaring both sides, we get

(2+3q)^2=(5\sqrt{q})^2

2^2+2(2)(3q)+(3q)^2=25q

4+12q+9q^2-25q=0

4-13q+9q^2=0

Splitting the middle term, we get

4-4q-9q+9q^2=0

4(1-q)-9q(1+q)=0

(4-9q)(1-q)=0

Using zero product property, we get

4-9q=0 and 1-q=0

q=\dfrac{4}{9} and q=1

q\approx 0.444 and q=1

Therefore, the break even points are 0.444 and 1.
