The rate of the boat when it's still in water is 7mph.

Based on the information, one can denote that the travel times are the same. The formula to calculate the rate will be:

d1/v1 = d2/v2

where

v = rate

d = distance of miles.

This will be:

t = 16/(v - 3) = 40/(v + 3)

Cross multiply

40(v - 3) = 16(v + 3)

40v - 120 = 16v + 48

Collect like terms

40v - 16v = 48 + 120

24v = 168

Divide through by 24

24v/24 = 168/24

v = 7 mph

The rate is 7mph. This shows the concept of the calculation for rate.

Answer:

$74.40

Step-by-step explanation:

first we find 20% of 62

62 * 0.2 = 12.4

20% of 62 is 12.4

now we add 12.4 to 62

62 + 12.4 = 74.4

I'll pick uo two points from the table.

P1 = (5, 11)

P2 = (7, 13)

From the diagram, the angles that are not congruent to the angle < 3, are

Explanations:

The given equation is:

3(5 - p) - 2(5 + p) = 3(p + 1)

Step 1: Expand all the brackets

15 - 3p - 10 - 2p = 3p + 3

Step 2: Collect like terms ( That is, let everything that has p go together)

15 - 10 - 3 = 3p + 3p + 2p ( Note that the sign changes when anything crosses the equality sign)

2 = 8p

Step 3: Divide both sides by 8

2/8 = 8p/8

1/4 = p

p = 1/4

p = 0.25

The value that completes the probability distribution is 0.22

The distribution of the discrete probability distribution is given as

x         3     4    5      6

P(x) 0.24  ?  0.28  0.26

Represent the blank value in the distribution with the variable y

So, we have the following representation:

P(x) 0.24  y  0.28  0.26

The sum of probabilities in a distribution is 1

So, we have

0.24 +y + 0.28 + 0.26 = 1

Evaluate the sum

y + 0.78 = 1

Evaluate the like terms

y = 0.22

If x variable represents the money your brother has without the value of the airplane ticket, then, the expression x + 637 is the total money he has at the beggining.

In the sense of an inequality, it means x + 637 must be lower or equal than 2000 dollars, which was the initial money yoir brother had.

Then, you have:

x + 637 ≤ 2000

to solve the previous inequality, subtract 637 both sides:

x + 637 - 637 ≤ 2000 - 637 simplify both sides

x ≤ 1363

Hence, the solution to the ineuqality is x ≤ 1363

By using the property of linear pair we can prove that m∠2=m∠3 .

Let us use the template that is provided to find the solution.

1. ∠1 and ∠2 are supplementary           (Linear pair)

 ∠3 and ∠4 are supplementary.

2.m∠1 + m∠2 = 180°                        (definition of supplementary angles.)

3.m∠3 + m∠4 = 180°                        (definition of supplementary angles.)

4.m∠1 + m∠2 = m∠3 + m∠4            (Substitution property)

or, m∠1 + m∠2 = m∠1 + m∠3

5. m∠1 =m∠4                                    (given)

6. m∠2 = m∠3                                  ( Subtraction property)

Therefore we can see that the two angles are equal due to the properties of linear pair and substitution property.

A linear pair of angles is formed when two  straight lines intersect at only 1 single point. The angles are known to be a linear pair  if they exactly follow the point where the two straight lines intersect only in a straight line. The sum of the angles in a pair of linear equations is always equal to 180°.

The percentage increase of the airline ticket is 45.24%

The concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original. An increase of 5 percent would indicate that, if you split the original value into 100 parts, that value has increased by an additional 5 parts.

Mathematically, the percentage increase of a quantity can be written as

[tex]\% increase =\frac{change in quantity}{original quantity} * 100[/tex]

Let's substitute the values given into the equation and find the percentage increase.

[tex]\% increase =\frac{change in quantity}{original quantity} * 100\\\% increase = \frac{305 - 210}{210} *100\\\% increase = 45.24\%[/tex]

The increase in percentage of the ticket price is 45.24%

If the airline charges an additional $50 with the new ticket price, the percentage increase will remain the same because assuming the baggage fees is also applicable to the old price, there won't be an change in the percentage increase.
