It takes a boat going upstream 11 hours and 9 hours downstream. What is the speed of The boat if the current is 2mph

Answers

well the speed of the boat changes depending on if it is up or down stream.
if it is going down stream it is with the current so there is a 2 mph assistance.
if upstream then 2 mph resistance.
i feel like there should be a given distance
11 hours to get to where, how far?
or simply answer 11-2=9 and 9+2=11. So possibly average it at 10.
Remark
You don't need the distance. The only thing that matters is the times (and assuming the same rate is used no matter what the current is doing). The distance coming and going is the same.

d_coming = d_going
t upstream = 11 hours
t downstream = 9 hours
current = 2 mph
rate_up = rate_down = r

General formula
d = r * t

Specific Formula
11(r - 2) = 9(r + 2) Note he seems faster with less time. That olnly means that the current is going in the same direction he is.

Solve
11(r - 2) = 9(r + 2)
11r - 11 =9r + 18    add 11 on both sides.
11r = 9r + 18 + 11  
11r = 9r + 29          subtract 9r from both sides.
11r - 9r = 29 
2r = 29                   divide by 2
r = 29/2
r = 14.5

Answer
The speed of the boat is 14.5 miles per hour.

A new, trendy department store is experiencing exponential growth across America. The chain began in 2004 when it opened 16 stores in Texas. Since then, it has grown by 35% in new store openings each year. Create an exponential function below to show the number of stores each year, x, since 2004.

Answers

The equation is y=16(1.35)ˣ.

This equation is of the form y=a(1+r)ˣ, where a is the initial amount, r is the rate of growth expressed as a decimal number, y is the total, and x is the amount of time.  For our problem, a is 16; b is 0.35 (35%=35/100=0.35).  This gives us the equation above.

find the interquartile range for the data set: 10,3,8,6,9,12,13

Answers

Answer:

The interquartile range would be 6.

Step-by-step explanation:

3, 6, 8, 9, 10, 12, 13,

Median: 9

Lower quartile (Q1): 6

Upper quartile (Q2): 12

(IQR) Interquartile Range: 12 - 6 = 6

The interquartile range for the data set is, 6

We have to given that,

The data set is,

⇒ 10,3,8,6,9,12,13

We can arrange data set in ascending order,

⇒ 3, 6, 8, 9, 10, 12, 13

Hence, First quartile (Q₁) = 6

Second quartile (Q₃) = 12

Hence, The interquartile range for the data set is,

Interquartile range = 12 - 6

Interquartile range = 6

A polygon is broken up into 4 non-overlapping triangles by drawing lines from one vertex to all other non-adjacent vertices. What is the name of the polygon?

A) Octagon
B) Hexagon
C) Heptagon
D) Quadrilateral

Answers

Answer :

The Correct Option is B) Hexagon

Step-by-step explanation :

Let number of sides in a polygon be n

The triangles are created by drawing the diagonals from one vertex to all the others.

Since there is no overlapping of the triangles so no diagonal will be drawn back to itself, and the diagonals to each adjacent vertex would lie on top of the adjacent sides, therefore number of diagonals from a single vertex is three less the the number of sides, or n - 3 and the number of triangles is one more than that, so n - 2.

⇒ Number of triangles = number of sides in polygon - 2

⇒ Number of triangles = n - 2

⇒ n = 4 + 2

⇒ n = 6

And the polygon containing 6 sides is called Hexagon

Hence, the correct Option is B) Hexagon

Answer:

b

A square garden has a perimeter of 60 yards. If one yard is approximately 0.9 meters, which of the following best represents the area of the garden in square meters?

Answers

Final answer:

To find the area of a square garden in square meters given its perimeter in yards, we first determine the side length by dividing the perimeter by 4, then convert this length into meters using the conversion rate, and finally square this metric side length to get the area in square meters.

Explanation:

The question you've asked involves calculating the area of a square garden in square meters given its perimeter in yards and a conversion factor between yards and meters. To solve this, we first determine the length of one side of the square garden using the given perimeter. The formula for the perimeter of a square is 4 × side length, so to find the side length, we divide the perimeter by 4. Given a perimeter of 60 yards, the side length is 15 yards.

To convert the side length into meters, we use the conversion factor that 1 yard is approximately 0.9 meters. Therefore, 15 yards × 0.9 meters/yard gives us 13.5 meters. Lastly, to find the area of the garden in square meters, we square the side length in meters, which is 13.5 meters × 13.5 meters = 182.25 square meters. This completes our calculation, showing that the area of the garden is approximately 182.25 square meters.

Lavender rolled a number cube 90 times. the outcome of the number 6 occurred 18 times. Compare the theoretical to the experimental probability of rolling the number 6.

Answers

By comparing the theoretical probability of 1/6 with the experimental probability of 1/5, one can see that the experimental probability is one that is slightly higher.

What is the outcome of the number

Based on the question, to compare the theoretical and experimental probabilities of rolling the number 6, one have to calculate both probabilities.

The theoretical probability is seen as the expected probability according to the assumption of a fair six-sided number cube.

Based on the fact that there are six equally likely outcomes (numbers 1 to 6) on the cube, the theoretical probability of rolling a 6 is 1/6.

So, the experimental probability is based on the actual outcomes observed in Lavender's 90 rolls.

According to the given information:

Lavender rolled the cube 90 times and got the outcome of 6 in 18 of those rolls.

So: Experimental probability = Number of successful outcomes / Total number of outcomes

= 18 / 90

= 1/5

Hence, the experimental probability of rolling the number 6 is 1/5.

Since the experimental probability is slightly higher, one can say that it could be as a result of random variation or a biased number cube.

Anne plans to increase the prices of all the items in her store by 5%. To the nearest cent, how much will the artist save if the artist buys a canvas and a frame that each measure 24 by 36 inches before the price increase goes into effect

Answers

Answer:

Step-by-step explanation:

Let the cost of canvas be $x per sq inches.

Measurement of the canvas bought by the artist is

24 × 36 inches

Area of canvas = 24×36= 864 sq inches

Cost of canvas = 864x

New cost of canvas =x+5% of x

=x+0.05x

=1.05x

New Cost of canvas = 907.20x

Increase in price=907.20x-864x=43.2x

Percentage = [tex]\frac{43.2x}{864x}*100[/tex]

= 5%

Hence artist is going save 5% of cost by buying sheet today.

Answers

Final answer:

Calculate the probabilities of selecting specific pairs of blouses from Maddie's closet with different colors.

Explanation:

1. P(black and yellow):

Number of ways to select 1 black blouse out of 4 black blouses = 4Number of ways to select 1 yellow blouse out of 2 yellow blouses = 2Total number of ways to select 2 blouses out of 11 blouses = 11C2 = 55

Therefore, P(black and yellow) = (4/55) * (2/11) = 8/605

2. P(green and green):

7. Two lines that intersect to form right angles are called what? A. Perpendicular lines B. Parallel lines C. Line segments D. Skew lines

Answers

The answer to the above question can be explained as -

Perpendicular lines are the lines that intersect each other or meet each other at 90 degrees, thus form a right angle.

The parallel lines are the lines that do not meet each other.

Thus, the answer to -

"Two lines intersect each other to form right angles are called" is - A. Perpendicular Lines.

Final answer:

Perpendicular lines are two lines that intersect each other forming a right angle (90 degrees). They are different from parallel lines (which do not intersect), line segments (parts of a line with two endpoints), and skew lines (non-intersecting and non-parallel lines in different planes).

Explanation:

The correct answer is A. Perpendicular lines. Perpendicular lines are two lines that intersect each other at right angles, which means they form a 90-degree angle. This kind of intersection is common in geometry, and you will encounter it frequently in your studies. This contrasts with parallel lines, which do not intersect at all, and line segments, which are parts of a line with two endpoints. Skew lines are lines that do not intersect and are not parallel, usually because they exist in different planes.
