4x = 112

x = 28

(2(28)-5)= 51

(2(28)+1) = 57

Write an equation for the amount of money, , that will be collected if boxes of chocolate bars are sold. Which is the independent variable and which is the dependent variable

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Let amount of money = C

If the number of chocolate bars sold = x

Let cost per chocolate bar = p, since cost per bar isn't stated

Amount of money that will be collected :

C(x) = P * x

The dependent variable is the Amount of money that will be collected as the amount of money depends on the number of chockate bars sold

The number of chocolate bars sold us the independent variable as it dictates the amout of money to be collected, hence it is the predictor variable.

The two dot plots show the number of miles ran by 14 students at the beginning and at the end of the school year compare each measure of the two dot plots

Answers

The two dot plots are missing, so i have attached it.

Answer:

The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles

Step-by-step explanation:

From the attached image, we are told to compare the means for each plot to the nearest tenth.

Mean = Σx/n

Now, from the image, total number of miles run by the 14 students at the beginning of the school year is;

(1 × 7) + (2 × 8) + (4 × 9) + (4 × 10) + (2 × 11) + (1 × 12) = 133

Mean of miles run at the beginning of the school year = 133/14 = 9.5 miles

Again, from the table, total miles run at the end of the school year = (2 × 8) + (2 × 9) + (4 × 10) + (3 × 11) + (3 × 12) = 143

Mean of miles run at the end of the school year = 143/14 = 10.2 miles

Thus;

The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles

Answers

Answer:

√{99×33×3}=√{33×3×33×3}=√(33²×3²)=±33×3=±99

Answer:

99

Step-by-step explanation:

Cause 33×3=99 ,and the function of the root is to get the number that we multiply it ti itself

For example [tex]\sqrt{4}[/tex] =2 cause 2×2=4 ,so[tex]\sqrt{2*2}[/tex] =[tex]\sqrt{4}[/tex] which is =2

so [tex]\sqrt{99^{2} }[/tex] =99

m^2 - 64n^2

Answers

Answer:

(n - 8n)(m+8n)

Step-by-step explanation:

x² - y² = (x - y)(x + y)

In this situation, the "x" = m and the "y" = 8n

So,

m² - 64n² = (n - 8n)(m+8n)

Answer:

(m - 8n)(m + 8n)

Step-by-step explanation:

m² - 64n² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

m² - 64n²

= m² - (8n)²

= (m - 8n)(m + 8n)

casey has the faster rate

Step-by-step explanation:

first multiply jessicas race distance and time by 2

30 * 2

= 60    

5 * 2

= 10

we did that so both jessicas time and caseys time was the same, making it easier to solve ( also by this point we already know who has the faster rate )

now we are going to divide both of their times and distances by 5

casey

10/5

= 2

45/5

= 9

jessica

10/5

= 2

60/5

12

the step is to divide their times/distances once again but this time by 2

casey

2/1

= 1

9/2

= 4.5

jessica

2/1

= 1

12/2

= 6

and our answer is 4.5 or casey !

4.5 > 6

Find the volume of the Cone. Use 3.14 for . Round your answer to the nearest hundredth ( 2 decimals). Show your work in this question, and record your answer in the next question.

Answers

Answer:

2,616.67cm³

Step-by-step explanation:

Find the diagram attached

volume of the cone = πr²h/3

r is the radius = 10cm

h is the height = 25cm

Substitute

V = 3.14(10)²*25/3

V = 314*25/3

V = 7850/3

V = 2,616.67cm³

Hence the volume of the cone to the nearest hundredth is 2,616.67cm³
