Step-by-step explanation:

50.94339623 percent boiii

Answer:

50.9%

Step-by-step explanation:

We are asked to find 27 pounds of recyclable trash is what percentage of the barrel of 53 pounds of trash.

We need to find 27 is what percent of 53. We can represent this information in an equation as:]

[tex]\frac{27}{53}\times 100[/tex]

[tex]0.5094339\times 100[/tex]

[tex]50.94339\%\approx 50.9\%[/tex]

Therefore, 27 pounds of recyclable trash is 50.9% of the barrel of 53 pounds of trash.

If you divide 7 by 2 it equals 3.5 meaning each game is 3.5 dollars.  So you can find how much any number of games would be by using this equation g (3.5) = c  For example, if there were 3 games then you would do 3 (3.5) = c and the cost would be 10.5 dollars.  

Final answer:

The relationship between the cost and the number of games bowled can be represented by the equation c = 3.5g, where c is the total cost and g is the number of games bowled.

Explanation:

To determine the relationship between the cost (c) and the number of games (g) bowled, we need to find a formula that connects these two quantities based on the information provided. Given that bowling two games costs $7 and bowling four games costs $14, we can see that the cost is directly proportional to the number of games bowled. This means for every game bowled, there is a fixed rate being paid.

Let's break down the information given:

2 games = $7

4 games = $14

From this, we can see that each game costs $3.50 because $7 divided by 2 equals $3.50. Therefore, the relationship between the cost and the number of games can be represented by the equation:

c = 3.5g

Where c represents the total cost and g represents the number of games bowled. This equation can be used to calculate the cost for any number of games bowled.

i bleieve the answer is 1796

Out of 4041 students in a school where 5/9 are girls, the number of boys in the school will be 1796.

In this mathematics problem, we are looking to find the number of boys in a school where we know the total number of students (4041) and the proportion that are girls (5/9). To start, you can determine the number of girls in the school by multiplying the total number of students by the proportion of students that are girls (4041 * 5/9 = 2245). Taking this number of girls away from the total number of students gives us the number of boys: 4041 - 2245 = 1796. So, out of 4041 students, 1796 of them are boys.

Answer:

6

Step-by-step explanation:

a pex

Let's have the first number be x, the second number y, and the third number z.

Because the second number is six more than the first, y = x + 6.

Because the third number is twice the first, z = 2x.

The three numbers added together equals 26, so 26 = x + y + z.

Let's substitute y = x + 6 and z = 2x into 26 = x + y + z.  This gives us:

26 = x + x + 6 + 2x

26 = 4x + 6

We subtract 6 from both sides of the equation and divide by 4 to get:

5 = x

Now, we'll put x = 5 into our previous to equations to find y and z:

y = 5 + 6

y = 11

z = 2*5

z = 10

Let's check out answer.  10 + 11 + 5 = 26.  10 is twice of 5 and 11 is 6 more than 5.  Thus our three numbers are 10, 11, and 5.

The three numbers are 5, 11 (5 + 6), and 10 (2 * 5)

Let's call the first number x

The second number is 6 more than the first, so it is x + 6

The third number is twice the first, so it is 2x

The sum of the three numbers is 26, so we have the equation x + (x + 6) + 2x = 26

Combining like terms, we get 4x + 6 = 26

Subtracting 6 from both sides, we get 4x = 20

Dividing both sides by 4, we get x = 5

So the three numbers are 5, 11 (5 + 6), and 10 (2 * 5)

Step-by-step explanation:

"The correct answer is that diagrams showing how matter moves through organisms and the environment are called cycles because they depict continuous, circular pathways.

In ecosystems, matter is not created or destroyed but is continuously recycled. This recycling process occurs in a loop or cycle, where matter moves from the environment to organisms and then back to the environment. For example, in the carbon cycle, carbon dioxide is taken in by plants during photosynthesis, then passed on to animals that consume the plants, and eventually returned to the environment through processes like respiration and decomposition.

These cycles are essential for the sustainability of ecosystems because they ensure that nutrients and other materials are reused and not depleted. The term ""cycle"" reflects the repeating and ongoing nature of these processes, highlighting the interconnectedness and interdependence of organisms and their environment. By using diagrams to represent these cycles, we can visualize and better understand the complex interactions and pathways that matter follows in ecosystems."

The first option is the right answer

Range are the y-values. Plug the x-values into the equation and solve for y.

f(x) = 3x - 2

f(-1) = 3(-1) - 2

     =   -3  - 2

f(0) = 3(0) - 2

     =   0  - 2

      = -2

R: -5 ≤ y < -2   ⇒   [-5, -2)

********************************

f(x) = 2x + 3

f(0) = 2(0) + 3

     =   0  + 3

     =    3

f(5) = 2(5) + 3

      =  10 + 3

If the street is already 24 m wide, and it is being expanded by 125%, then the correct answer is C. 30 m!

125% simply means 1 1/4.     1/4 of 24 is 6.    So, you have 24 + 6 = 30!

Answer:

The correct answer is C: the new street should be 30m wide.

Step-by-step explanation:

This is a simple problem of per-cents. Perhaps the easiest way to do it is to use a basic ‘‘rule of three’’. In this particular case the 100% is the width of the old street, i.e. 24 m; and we want to know the new width, that is 125% of the old street. So,

                   24 ---- 100%

                    x  ----- 125%

To find x we use the formula

[tex]x = \frac{24*125}{100} = 3000/100=30[/tex]

So, the width of the new street is 30m.

The answer you want would be C.52

Reason: 32+5= 37 that is the 1st and 2nd term. 37+5=42 thatis the 3rd term. 42+5=47 that's the 4th term. And 47+5=52 that's the 5th term.

When the 12 numbers are listed in order, they are ...

... 13, 15, 18, 20, 23, 23, 27, 29, 30, 32, 36, 38

The extreme values are 13 and 38. Only the third plot has the ends of the whiskers on these values.

Since there are an even number of numbers, the median is the average of the middle two: (23 +27)/2 = 25. Only the third plot shows the median at 25.

Since each half of the data set has an even number of numbers, the 1st and 3rd quartile values are the averages of the middle two numbers in each half:

The third plot has the ends of the box in these places, confirming it is the correct choice.

The appropriate choice is the third one.

Answer:

It's true that  [tex]JK \cong MN[/tex]

Step-by-step explanation:

If the lengths of two line segments are equal, then they are said to be congruent to each other.

[tex]JK[/tex] has endpoints as [tex]J(-1, 10)[/tex], [tex]K(-5,2)[/tex] and [tex]MN[/tex] has endpoints as [tex]M(9,-7), N(1,-3)[/tex]

Formula for finding the length of line segment: [tex]\sqrt{(x_{1}-x_{2})^2+(y_{1}-y_{2})^2}[/tex] , where [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] are two endpoints.

So, the length of [tex]JK = \sqrt{(-1-(-5))^2+(10-2)^2}= \sqrt{(4)^2+(8)^2}= \sqrt{16+64}= \sqrt{80}[/tex]

and the length of [tex]MN=\sqrt{(9-1)^2+(-7-(-3))^2}= \sqrt{(8)^2+(-4)^2}= \sqrt{64+16}= \sqrt{80}[/tex]

As, the lengths of [tex]JK[/tex] and [tex]MN[/tex] are equal, so we can say that, [tex]JK[/tex] is congruent to [tex]MN[/tex].

To determine if JK is congruent to MN, use the distance formula to find the lengths of the line segments. If the lengths are equal, then the segments are congruent.

To determine if JK is congruent to MN, we need to compare the lengths of these line segments. The formula for finding the length of a line segment with endpoints (x1, y1) and (x2, y2) is the distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2).

Since the lengths of JK and MN are equal (sqrt(80) = sqrt(80)), we can conclude that JK is congruent to MN.
