Lilianna discovered that the ratio of kilometers to miles is 1 to 0.6 if its 60 kilometers to Moncton then how many miles does it take to get to Moncton.

Answers

Answer: 36 miles.

Step-by-step explanation: Ratio of 1 to 0.6 means 1:0.6 or [tex]\frac{1}{0.6}[/tex].

So, if to Moncton is 60km:

[tex]\frac{1}{0.6}=\frac{60}{y}[/tex]

[tex]y=60.0.6[/tex]

y = 36

To Moncton, it is 36 miles.

cost $2. If 295 tickets were sold and a total of $950 was collected, how many students' tickets were sold?

Answers

Answer:

175

Step-by-step explanation:

Let A be the number of adult tickets and S be the student's tickets

{A + S = 295 or S = 295 - A

{5A + 2S = 950

5A + 2(295 - A) = 950

5A + 590 - 2A = 950

3A = 360

A = 120

S = 295 - 120 = 175

Write an algebraic expression that models the word phrase.
The product of 8 and the sum of a number x and 14

Answers

Answer:

8(x + 14)

Step-by-step explanation:

The term product signifies multiplication in mathematics. However, in order to find a product, we must have two or more terms to multiply. Because we are finding the product of 8 and the sum of a number x and 14, we will place the sum in parentheses to show they are being added together.

Using this knowledge, we are left with the sum in parentheses (x + 14) and the number 8 to multiply it.

To simplify, this can be written as 8(x + 14).

Answers

Step-by-step explanation:

We can prove this by using similar triangles. We know that angle ABE and ACD are SIMILAR(we know that by the sign in between them).Therefore, we also know that CDA and BEA are similar, and EAB and DAC are similar. Since all the angles are similar, we also know that the side lengths are equal in proportion. AB/AE is equal to AC/AD. When assigned values, that would create a proportion that is equal since the smaller triangle is similar to the bigger one. If you want to create a proof, break each statement into its own section.

What is the distance between 7.65 and -4.18 on a number line

Answers

Answer:

11.83

Step-by-step explanation:

11.83 because you would add them to find distance and 7.65+4.18=11.83

The required distance on the number line between the points -4.18 and 7.65 is 11.83

What is a number line?

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Given that,  the distance between 7.65 and -4.18 on a number line

On the number line, -4.18 lies on the left of the zero, and 7.65 lies on the right, so the required distance would be the addition of the two points. So,

Distance = 7.65 - (-4.18)

Distance = 7.65+4.18

Distance = 11.83

Thus, the required distance on the number line between the points -1.85 and 7.36 is 9.21.

15. y = 25x - 15

16. y = 7x - 1

17. [tex]a_n = 4 + 6(n-1)[/tex]

Step-by-step explanation:

13. f(3) means plug in 3 for x.

f(3) = 7(3)² + 5 = 7(9) + 5 = 63 + 5 = 68

14. Write out what you know. 0.50 inches per hour is the rate of snowfall, or your m, or your slope. m = 0.50. If x is hours passed and y is inches of snowfall, then you also know that at x = 4, y is 10. Plug these into the standard linear formula: y = mx + b => 10 = 0.50(4) + b

Solve for b:

10 = 0.50(4) + b

10 = 2 + b

b = 8

Remember, x and y are variables, not constants, but m and b are always the same for some given function. So your answer is y = 0.50x + 8

15. Write out what you know. If x is hours passed and y is distance from home in miles, then we need to find the slope and y-intercept using what you're given. How do you find the slope? Use this: [tex]m (or slope) = \frac{y_2 - y_1}{x_2 - x_1}[/tex].

You have two points given: (3, 60) and (7, 160). So [tex]m = \frac{160-60}{7-3} = \frac{100}{4} = 25[/tex]

Now, just use either of these points to find b, or your y-intercept.

y = mx + b

Let's just use (3, 60); either one would work though.

[tex]60 = 25(3) + b[/tex]

60 = 75 + b

b = -15

To make the equation, use the values for m and b that you found.

m = 25 and b = -15, so y = 25x - 15

16. In y = mx + b, b is the y-intercept, but it's also how much the graph shifts up or down from its "original" position. I don't really want to explain this, but you can experiment with y = x + something (like try y = x + 1, y = x - 1, y = x, y = x + 3) and you'll see the pattern of what I'm talking about. To move y = 7x + 3 down 4 units, just subtract 4 from 3 to get -1: you will get y = 7x - 1.

A solid cubiod measures 7cm, 5cm,3cm. (a) Calculate the total surface area of the cubiod. (b) A cube has the same volume as the cubiod. Calculate the length of an edge of this cube

Answers

Answer:

Te total surface area (TSA) of the cuboid is the sum of the area of its 6 faces

if the cuboid has width(w)=7 cm, Height (h)=3cm., length(h)=5cm

A=lw=5*7=35 cm²

A2=hw=3*7=21

A3=lh=5*3=15

TSA=2(lw+hw+lh)

TSA=2(35+21+15)

TSA=2(71)=142cm²

volume of the cubiod=l*w*h

V=lhw

V=7*5*3= 105 cm³

the length of an edge of this cube:

since it is a cube then all sides are equal l=w=h

√105= 10.247 ( rounded to the nearest hundredth)









The The U.S.based motorcycle manufacturer says that it expects to build 140,000 motorcycles this year, up from 126.000 last year. Find the percent of increase in production.

Answers

Answer:

The us based motorcycle manufacturer says that it expects to build 140,000 motorcycles this year up from 126,000 last year.

This means the increased production is

144,000 - 126,000 = 18,000

The percentage change in production can

be found using the formula as listed below

PERCENTAGE INCREASE = change / initial × 100

Substitute the values we get

18,000/126,000 × 100

14.28 = percentage increase

Answers

Answer: It will take her more than 9 weeks.

Step-by-step explanation:

If she already has $150 that will be constant and if she can save $45 per week  the we will have the expression 45w  where w is the number of weeks.

Together it will  be  150 + 45w    

Now the money has to be at least $560  so it will be

150 + 45w ≥ 560  Now solve for w

-150              -150

45w ≥ 410

w ≥ 9.1

The following are the means and standard deviations of some well-known standardized tests, referred to as Test A, Test B, and Test C. All three yield normal distributions.

Test Mean Standard deviation
Test A 500 100
Test B 150 8
Test C 70 15

Required:
a. A score of 450 on Test A corresponds to what score on Test B?
b. A score of 625 on Test A corresponds to what score on Test C?

Answers

Answer:

(a) A score of 450 on Test A corresponds to a score of 146 on Test B.

(b) A score of 625 on Test A corresponds to a score of 88.75 on Test C.

Step-by-step explanation:

We are given the means and standard deviations of some well-known standardized tests referred to as Test A, Test B, and Test C. All three yield normal distributions.

Test         Mean       Standard deviation

Test A       500                    100

Test B       150                       8

Test C        70                       15

So, [tex]\mu_A[/tex] = 500 and [tex]\sigma_A[/tex] = 100

[tex]\mu_B[/tex] = 150 and [tex]\sigma_B[/tex] = 8

[tex]\mu_C[/tex] = 70 and [tex]\sigma_C[/tex] = 15

(a) We have to find a score of 450 on Test A corresponds to what score on Test B.

For this, firstly we will find the z-score for a score on Test A and then equate with that of Test B.

      z-score of 450 on test A = [tex]\frac{X_A-\mu_A}{\sigma_A}[/tex]

                                                = [tex]\frac{450-500}{100}[/tex] = -0.5

So, this z-score corresponds to the score on test B, i.e;

       z-score on test B = [tex]\frac{X_B-\mu_B}{\sigma_B}[/tex]

                          -0.5    = [tex]\frac{X_B-150}{8}[/tex]

                          [tex]X_B= 150-(0.5 \times 8)[/tex]

                                 = 150 - 4 = 146

Hence, a score of 450 on Test A corresponds to a score of 146 on Test B.

(b) We have to find a score of 625 on Test A corresponds to what score on Test C.

For this, firstly we will find the z-score for a score on Test A and then equate with that of Test C.

      z-score of 625 on test A = [tex]\frac{X_A-\mu_A}{\sigma_A}[/tex]

                                                = [tex]\frac{625-500}{100}[/tex] = 1.25

So, this z-score corresponds to the score on test C, i.e;

       z-score on test C = [tex]\frac{X_C-\mu_C}{\sigma_C}[/tex]

                          1.25    = [tex]\frac{X_C-70}{15}[/tex]

                          [tex]X_C= 70+(1.25 \times 15)[/tex]

                                 = 70 + 18.75 = 88.75

Hence, a score of 625 on Test A corresponds to a score of 88.75 on Test C.
