Let x represent the speed of of boat.

We have been given that the river current is 3 miles per hour.  

The speed of boat upstream will be [tex]x-3[/tex].

The speed of boat downstream would be [tex]x+3[/tex].

[tex]\text{Time}=\frac{\text{Distance}}{\text{Speed}}[/tex]

We have been given that you travel 2 miles downstream to a marina for supplies, and then you travel 3 miles upstream to a dock.

We can represent this information in an equation as:

[tex]\text{Time}=\frac{2}{x+3}+\frac{3}{x-3}[/tex]

Since the speed of the boat is 18 miles per hour, so we will substitute [tex]x=18[/tex] in above equation and solve for time.

[tex]\text{Time}=\frac{2}{18+3}+\frac{3}{18-3}[/tex]

[tex]\text{Time}=\frac{2}{21}+\frac{3}{15}[/tex]

[tex]\text{Time}=\frac{2}{21}+\frac{1}{5}[/tex]

[tex]\text{Time}=\frac{2\cdot 5}{21\cdot 5}+\frac{1\cdot 21}{5\cdot 21}[/tex]

[tex]\text{Time}=\frac{10}{105}+\frac{21}{105}[/tex]

[tex]\text{Time}=\frac{31}{105}[/tex]

[tex]\text{Time}=0.295238095[/tex]

Since time is in hours, so let us convert our given time in minutes.

1 hour = 60 minutes.

[tex]\text{Time}=0.295238095\times 60\text{ minutes}[/tex]

[tex]\text{Time}=17.7142857\text{ minutes}[/tex]

Rounding to nearest tenth of minute.

[tex]\text{Time}\approx 17.7\text{ minutes}[/tex]

Therefore, it will take approximately 17.7 minutes for the boat to take the trip.

Answer:

Dilation

Step-by-step explanation:

The transformation maps the large triangle onto the small triangle will be dilation. Then the correct option is A.

A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.

Dilation does not change the shape, but changes the size of the geometry.

2 right triangles have identical angle measures but different side lengths.

The first triangle has side lengths of 6, 10, 8 and the second triangle has side lengths of 3, 5, 4.

The transformation maps the large triangle onto the small triangle will be

6 / 3 = 10 / 5 = 8 / 4 = 2

Then the small triangle is dilated by 2.

Then the correct option is A.

The value 1500 in the expression represents option A. The original number of grams of the radioactive isotope present.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given an exponential expression,

The number of grams of a radioactive isotope present after t years is 1,500(1/2)^t.

Here t is the number of years.

1/2 is the rate of decay of the isotope.

1500 is the initial amount.

We can say that the expression equals 1500 when t = 0.

But it is given that t > 0.

That is, 1500 is the amount which is equal to the original number of  grams of isotope.

Hence the number 1500 represents the original number of grams of the radioactive isotope present.

|X-4|<3

-3 <x-4 <3

-3+4 <x <3+4

1 <x <7

The solution to the inequality |x-4| < 3 is x> 1 or x<7

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

An inequality,

|x-4| < 3.

Simplifying,

-3 < x - 4 < 3

Adding 4 to all sides,

1 < x < 7

Therefore, the solution is 1 < x < 7.

A straight line from home plate to second base would have distance:

D = sqrt(2 x 90^2) = 127.3 feet

=> Option A is correct

Hope this helps!

:)

The distance from the home plate to second base in a straight line is required.

The required distance is option A 127.3 feet.

A baseball field is in the shape of a square this means that all corners have the angle [tex]90^{\circ}[/tex]

So, two sides of the square can act as legs of a right triangle and the diagonal can act as the hypotenuse.

A straight line between the home plate and second base would be the diagonal of the square.

The length of each side of the square is 90 feet.

Applying the Pythagoras theorem

[tex]d=\sqrt{90^2+90^2}\\\Rightarrow d=90\sqrt{2}\\\Rightarrow d=127.279\approx 127.3\ \text{feet}[/tex]

Answer:

The length and width of the field are 68ft and 32ft respectively

Step-by-step explanation:

Given:

Rectangular Playing Field

Perimeter. P = 200 ft

Required

The dimension of the field (Length and Width)

Let L and W represent the length and the width of the field.

From the question, L is 4 more than twice of W.

This means

L = 4 + 2W

Provided that the playing field is rectangular in shape;

We need to make use of the formula of perimeter of a rectangle.

P = 2(L + W)

Substitute 200 for P

200 = 2(L + W)

Divide through by 2

[tex]\frac{200}{2} = \frac{2(L + W)}{2}[/tex]

100 = L + W

Recall that L = 4 + 2W

Substitute 4 + 2W for L

100 = L + W becomes

100 = 4 + 2W + W

100 = 4 + 3W

Subtract 4 form both sides

100 - 4 = 4 + 3W - 4

96 = 3W

Divide both sided by 3

[tex]\frac{96}{3} = \frac{3W}{3}[/tex]

32 = W

W = 32

Recall that L = 4 + 2W

Substitute 32 for W

L = 4 + 2(32)

L = 4 + 64

L = 68

Hence the length and width of the field are 68ft anf 32ft respectively
