irena’s boat traveled 76 miles downstream in 4 hours. on the way back it took her 5 hours and 30 minutes to travel 38.5 miles. i

Oxana [17]

Answer:

The speed of the boat in still water is 13 miles/hour.

The speed of the current is 6 miles/hour.

Step-by-step explanation:

Let the speed of the boat in still water be x

And speed of the current be y

When Irena's travelling downstream, the speed of the boat is:

$Speed=\frac{76 miles}{4 hours}=19 miles/hour$

Traveling down stream the speed of the boat will be :

$x+y=19$ ..(1)

When Irena's travelling upstream, the speed of the boat is:

Time taken by boat = 5 hours and 30 min = 5.5 hours (1 hour = 60 min)

$Speed=\frac{38.5 miles}{5.5 hours hours}=7 miles/hour$

Traveling down stream the peed of the boat will be :

$x-y=7$ ..(2)

On Solving both equation (1)and (2).

$x+y=19$

$x=19-y$ putting value of x in (2) equation

$19-y-y=7$

y = 6 miles/hour

Putting value of y in (1) equation:

$x+6=19$ , x = 13 miles/hour

The speed of the boat in still water is 13 miles/hour.

The speed of the current is 6 miles/hour.

ilia earns $15 for each job he completes as a handyman alongside his uncle. he calculates his total job expenses for supplies to

Dmitriy789 [7]

If you are asking how much money would he have after 20 jobs while earning 15$ for each, here is the answer and explanation.

llia will have 300$ after 20 jobs. If he gets 15$ for each job then 1 is 15$, 2 is 30$, and so on. So we multiply 20 jobs x 15$ and that gives us 300$. I Hope this helps

Tom's stockbroker offers an investment that is compounded continuously at an annual interest rate of 3.7%. If Tom wants a return

Anettt [7]

Answer:

It'll take 38.3 years to obtain the desired return of $25,000.

Step-by-step explanation:

In order to solve a continuosly coumponded interest question we need to apply the correct formula that is given bellow:

M = C*e^(r*t)

Where M is the final value, C is the initial value, r is the interest rate and t is the time at which the money was applied. Since he wants an return of $25,000 his final value must be the sum of the initial value with the desired return. So we have:

(25000 + 8000) = 8000*e^(0.037*t)

33000 = 8000*e^(0.037*t)

e^(0.037*t) = 33000/8000

e^(0.037*t) = 4.125

ln[e^(0.037*t)] = ln(4.125)

t = ln(4.125)/(0.037)

t = 1.4171/0.037 = 38.2991

t = 38.3 years

Which one of these shapes will tessellate? <br> Please leave the letter below

Katyanochek1 [597]

Answer:

Option D

Step-by-step explanation:

Out of all given options, Option D (the parallelogram) will tessellate the easiest.

Option B's shape (the Trapezoid) is also possible. However, it would take a little more work for it to tessellate. The trapezoid provided would not tessellate alone.

Option A and Option C's shape wouldn't tessellate because it would leave a gap. To add, Option C's shape is nearly impossible to tessellate.
