Solve the problem. The formula d = rt gives the distance traveled in time t at rate r. If a bicyclist rides for 2.3 hours and travels 41 miles, what was her average speed ?
Question options:

a: 38.7 miles per hour

b: 5.6 miles per hour

c: 17.83 miles per hour

d: 9.43 miles per hour

the coordinates of the point of intersection of the graphs of lines with

y=−2x+7 and y=0.5x−5.5

to find intersection we solve for x  and y

We replace -2x+7 for y in the second equation

−2x+7 =0.5x−5.5

Subtract 0.5x from both sides

-2.5x + 7 = -5.5

Subtract 7 on both sides

-2.5x = -5.5 - 7

-2.5x = -12.5

divide by -2.5 from both sides

x = 5

Plug in 5 for x in y=−2x+7

y=−2(5)+7

y = -10 + 7

y = -3

The point of intersection is (5,-3)

2 and 3/5 is equal to 2.6.

Being as the 2 is in front of the fraction, it is the whole number. This means in decimal form, it is to the left of the decimal point. Since there is no "fifths place" in a decimal, you must make it so it can go under the tenths, hundreths, thousanths or another place within the right side of the deciamal point. Simply multiplying 3/5 by 2/2 will give you 6/10. 6/10 as a decimal, is 0.6. Finally, add 0.6 and 2 together. Thus making 2.6 the answer.

Answer:

41 MPH

Step-by-step explanation:

Let's assume the original speed with or without, is around 82 miles, within 2 hours.

So in this case, it'd be half the miles, half the hours!

Solution:

Let the speed of cyclist without any wind = x miles per hour

   Speed of cyclist when speed of wind increases by 2 miles per hour =              (x + 2 )miles per hour

Also , relation that is given between speed of cyclist without wind and with wind is :Riding with the wind at her back, a cyclist takes an hour less time to cover 80 miles than without any wind.

Converting this statement into terms of equation:

[tex]\frac{80}{x}-\frac{80}{x+2}=1  \\\\ 160 = x^2 + 2x \\\\ x^2 + 2x - 160=0 \\\\ x= \frac{-2\pm\sqrt{4+640}}{2}, {\text {As speed can't be negative, so taking positive value of x}} Gives,  x =11.68[/tex]→→→To solve the Quadratic equation of type : a x² + b x + c=0, I have used discriminant method, to find the roots, which is x= [tex]\frac{-b\pm\sqrt{D=b^2-4ac}}{2a}[/tex]

Speed of cyclist without wind = 11.68 miles per hour

Speed of cyclist when wind is flowing = 11.68 +2 = 13.68 miles per hour

The LCM of 5/9 and 11/12

28000 + 3000x = 36000 + 2000x

Subtract 2000x from both sides: 28000 + 1000x = 36000

Subtract 28000 from both sides: 1000x = 8000

Divide both sides by 1000: x = 8.

Answer:

No, the two events "being in high school" and "GPA above 3.0" are not independent.

Step-by-step explanation:

If two events A,B are independent [tex]P(A|B)=P(A)[/tex]

P(high school | above 3.0) = [tex]\frac{14}{40}=0.35[/tex]

P(high school) = [tex]\frac{60}{100}=0.6[/tex]                                                                                                

So,0.35 ≠ 0.6

Since P(high school | above 3.0) ≠ P(high school), the events "being in high school" and "GPA above 3.0" are not independent.

The proportion of high school students with a GPA above 3.0 differs from the proportion of college students with a GPA above 3.0. Therefore, the events 'being in high school' and 'GPA above 3.0' are not independent according to the data provided.

To determine if "being in high school" and "GPA above 3.0" are independent events, we can check if the proportion of high school students with a GPA above 3.0 is the same as the proportion for college students. If the events are independent, the proportions should be equal.

From the two-way frequency table provided, we can calculate the proportions. There are 60 high school students and 40 college students. Among these, 14 high school students and 26 college students have a GPA above 3.0.

The proportion of high school students with a GPA above 3.0 is 14 out of 60, which simplifies to about 0.233.

The proportion of college students with a GPA above 3.0 is 26 out of 40, which simplifies to about 0.650.

Because these proportions are not equal, we can conclude that the events are not independent. Being in high school appears to have an impact on whether a student has a GPA above 3.0, based on this data set.

Therefore, the events 'being in high school' and 'GPA above 3.0' are not independent according to the data provided.

                                                      =  [tex]\frac{74}{3}[/tex] -  [tex]\frac{5}{6}[/tex]

                                                      =  [tex]\frac{148-5}{6}[/tex]

                                                      =  [tex]\frac{143}{6}[/tex]

                                                      =  [tex]23\frac{5}{6}[/tex]

He wants to divide the left over wrapping paper into 11 pieces.

[tex]23\frac{5}{6}[/tex] ÷ 11

[tex]\frac{143}{6}[/tex] ÷ 11

[tex]\frac{143}{6}[/tex] ×  [tex]\frac{1}{11}[/tex]

[tex]\frac{143}{66}[/tex]

Answer:

225, 225 and 252 meters

Step-by-step explanation:

Let  length of the 2 equal parts be each x m, then:-

2x + x + 27 = 702

3x = 702 - 27 =    675

x = 675/3

x = 225

So lengths of each parts are  225, 225, 252

To find the lengths of the three parts, we let the length of each of the two equal parts be 'x' and set up the equation 3x + 27 = 702. Solving for 'x' gives us that each of the two equal parts is 225 m, and the third part is 252 m.

The student is asking to find the lengths of three parts of a fence that has been cut, with two parts being equal in length and the third part being 27 m longer than the other two. Let's assume each of the two parts that are the same length is 'x' meters. Since the third part is 27 m longer, it would be 'x + 27' meters. According to the problem, the total length of the fence is 702 m.

Therefore, the sum of all three parts is:

x + x + (x + 27) = 702

Simplifying this, we get:

3x + 27 = 702

Subtract 27 from both sides:

3x = 675

Now, divide both sides by 3:

x = 225

So, the two equal parts are each 225 m long, and the third part is 225 + 27 = 252 m long.

The factors of 8 are...

8 is a composite number because has more numbers than itself and 1. A prime number like 5, only has 2 factors ( 1 and 5).

Part (A):

The area of the penalty box.

The dimensions of the penalty box are (15x-1) and (5x-7)

The area of rectangle = length * width

∴ The area of the penalty box = (15x-1) * (5x-7) = 75 x² - 110 x + 7

===================================================

Part (B):

The area of the goal box.

The dimensions of the goal box are (7x-1) and (x+3)

The area of rectangle = length * width

∴ The area of the goal box = (7x-1) * (x+3) = 7x² + 20x - 3

The area of the penalty box - The area of the goal box =

(75 x² - 110 x + 7) - (7x² + 20x - 3) = 68 x² - 130 x + 10

Answer:

6

Step-by-step explanation:

The x-intercept is the x-coordinate of the point on the line that intersects the x-axis. At the x-axis, all y-coordinates are 0. Let y = 0, and solve for x.

2x – 3y = 12

2x - 3(0) = 12

2x = 12

x = 6

The x- intercept of the graph is 6

The problem can be solved by following steps

2x-3(0)=12

2x=12

x=6

Hence the x-intercept is 6

Let's x represents the first odd integer

The next consecutive integer would be represented as x+2.

So x and x+2 being multiplied together will give us 1443:

(x)(x+2)=1443

x^2+2x=1443

x^2+2x-1443=0

By solving the quadratic equation using the quadratic formula, x will equal to 37 and -39.

Since the problem says "integers", so I'm assuming two pairs of consecutive integers would be ok.

With that said you 1st pair will be: 37,39

Your second pair will be: -37,-39.

This problem would be best modeled by an inequality.

Let t = the number of hours.

18 + 5t < 78

5t < 60

t < 12

The way the question sounds, it would not be a lessthan or equal to, because they want to spend less than 78.  It would be a less than or equal problem if they said "no more than 78"

Answer:

First answer

number of cats = 2

number of hamsters = 4

number of birds = 8

number of fishes = 1

Second answer

number of cats = 3

number of hamster = 6

number of  birds   =2

number of fishes =  4

Step-by-step explanation:

Let the number of cats be x . Let number of birds be y and Let number of fishes be z.

number of hamsters = 2 number of cats

                                    =2x

birds +cats + hamsters + fish = 15

 y +x +2x + z  = 15  

y +3x + z =  15

then number of hamsters = 2x

birds has legs = 2

hamster legs = 4

cats legs = 4

total legs  =40

2y+4x+4(2x) =40

2y+12x = 40

y+6x = 20   ,Since x ,y z are natural number   ,since x ,y and z are numbers of pets of each kind which have to be natural number ,therefore

Case 1 for y = 2   x = 3

for y = 8  x = 2

for y = 2 and x =3 ,we have

2+3(3) +z = 15

2+9+z = 15

11 +z = 15

 z = 15 -11 = 4

Case 2

for y= 8 and x=2 ,we have

8 +3(2) + z = 15

8 +6 +z = 15

   z =15-14 = 1

We have two answers for this problem

First answer

number of cats = 2

number of hamsters = 4

number of birds = 8

number of fishes = 1

Second answer

number of cats = 3

number of hamster = 6

number of  birds   =2

number of fishes =  4

For case 1   fish % =   [tex]\frac{1}{15} x100[/tex]=6.67 %

For case 2  fish =   [tex]\frac{3}{15} X100=20%[/tex]

Tina has 3 cats, 6 hamsters, 8 birds, and 0 fish, therefore 20% of her pets are cats.

First, let's denote the number of cats as 'x'. According to the question, the number of hamsters, which have twice as many as cats, is '2x'. Every cat and hamster has 4 legs. So the total number of legs from cats and hamsters is 4x (from cats) + 8x (from hamsters) = 12x. We know that the total number of legs is 40, so we can solve the equation 12x=40, therefore 'x', the number of cats, is approximately 3, making hamsters 6 (2x). This adds up to 9 pets, leaving us with 15 - 9 = 6 birds and fish. Since birds and fish have two legs and zero legs, respectively, the last 16 legs must belong to birds. That leaves the remaining pets (6-8=0) as fish.

As for the percentage of Tina's pets that are cats, we use the formula for finding a percentage:  (number of cats / total number of pets) * 100. So, (3 / 15) * 100 = 20%. Therefore, "20% of Tina's pets are cats".

When dividing exponents you subtract them by each other, but because r and s are not the same and represent a different type of number, we just show that they were subtracted by each other.

4^r-s

For this case we have:

By definition, two points are needed to find the equation of a line. We have a series of points given by:

[tex](x, y) = (time, cost)[/tex]

We chose two points:

[tex](t1, c1) = (1,180)\\(t2, c2) = (2,240)[/tex]

By definition, the formula of the slope is given by:

[tex]m =\frac{(c2-c1)}{(t2-t1)}[/tex]

Substituting:

[tex]m =\frac{240-180}{2-1}[/tex]

[tex]m =\frac{60}{1}\\m = 60[/tex]

Being a line of the form [tex]y = ax + b[/tex], we substitute a point and the slope found to find the cut point b.

[tex]180 = 60 * 1 + b\\180 = 60 + b\\b = 180-60\\b = 120[/tex]
