Answer:

35 subscribers

Step-by-step explanation:

Divide $43.75 by $1.25.

$43.75/$1.25 = 35

For each subscriber he gets, his service goes down by $1.25.

Since 35 * $1.25 = $43.75, for 35 new subscribers, his service will go down by $43.75.

He pays $43.75, so if the service goes down by $43.75, he will pay nothing since $43.75 - $43.75 = 0.

Answer: 35 subscribers

Follow below steps:

To determine how many users Mike must recruit for him to stream movies for free, we need to set up a simple algebraic equation. Mike's service costs $43.75 per month, and for each new subscriber he recruits, his rate is reduced by $1.25. Let's say the number of users Mike needs to recruit is represented by x.

The cost reduction for recruiting x users would be $1.25x. To get a free service, the total cost reduction must equal the monthly service cost of $43.75. Thus, the equation is $1.25x = $43.75.

To solve for x, we divide both sides by $1.25:

x = $43.75 / $1.25

x = 35

Therefore, Mike must recruit 35 new subscribers to stream movies for free.

To divide 64.8 by 7 using long division, calculate how many times 7 can be subtracted from each part of the number 64.8 in sequence. This results in the final answer of 9.25.

To find 64.8 divided by 7 using long division, first write down 64.8 with a division bar over it and 7 on the left side of the bar. You would write:

7 | 64.8

Next, ask: How many times does 7 go into 64? This is 9 times since 7 times 9 is 63. Record the 9 above the line and record the product (63) below 64. Subtract 63 from 64 to get 1.

Bring down the 8 (from 64.8) to the right of the 1. Now you have 18. Ask how many times does 7 go into 18? This is 2 times. So you add the digit 2 next to 9 on top of the bar. 7 times 2 is 14.

Subtract 14 from 18 to get 4. As the decimal point should be straight up from where it is in the 64.8, record a decimal point.

Now, since there's no more numbers to bring down, you can add a 0 to 40. 7 goes into 40, 5 times. Therefore, we add 5 next to the 2 after the decimal point. So, 64.8 divided by 7 is 9.25.

The correct answer is (B) Only (-3, 3).

To determine which ordered pair is a solution of the equation, you need to substitute the values of \( x \) and \( y \) into the equation and see if it holds true. Let's check:

For option A: (-4, 4)
Substituting into the equation: \( -3(-4) - 4 - 6 = 12 - 4 - 6 = 2 \) which is not equal to 0, so it's not a solution.

For option B: (-3, 3)
Substituting into the equation: \( -3(-3) - 3 - 6 = 9 - 3 - 6 = 0 \) which is equal to 0, so it is a solution.

Thus, the correct answer is (B) Only (-3, 3).

Answer:

12x < 200

Step-by-step explanation:

Substitute x = 12 into the left side of the inequality and compare with right side, that is

12 ÷ 12 = 1 < 12 ← not a solution

12 - 12 = 0 < 4 ← not a solution

12 × 12 = 144 < 200 ← this is a solution

To solve the equation a = 2x + 6xz for x, isolate x on one side of the equation by following the steps: subtract 6xz from both sides, factor out x, and divide both sides by (2 + 6z).

To solve the equation a = 2x + 6xz for x, we need to isolate x on one side of the equation. Here are the steps:

Start with the equation: a = 2x + 6xz

Subtract 6xz from both sides: a - 6xz = 2x

Factor out x on the right side: a - 6xz = x(2 + 6z)

Divide both sides by (2 + 6z): (a - 6xz) / (2 + 6z) = x

Therefore, the solution for x is x = (a - 6xz) / (2 + 6z).

Answer:

x < 3

Step-by-step explanation:

Apply distributive property on the left of the inequality to get rid of the parenthesis:

8+4x > 5x+5

subtract 4x from both sides to group all terms with x on the right:

8 > 5x-4x+5

8 > x +5

Now subtract 5 from both sides to collect all numerical terms on the left:

8 - 5 > x

3 > x

Therefore the solution to the inequality are of those real numbers strictly smaller than 3.

The inequality can be written as x < 3 or also as we had it initially: 3 > x

NO NUMBER VARIABLES CAN BE CALLED A FUNCTION

Covert the ratios so they are all the same measurement type.

A. 5 feet = 5 x 12 = 60 inches.

The scale becomes 1:60

B. 1:30

C. 12 yards = 12 x 3 = 36 feet x 12 = 432 inches.

The scale is 12:432  = 1:36

D. 1 meter = 39.37 inches.

1 inch = 2.54 cm

39.37 x 2.54 = 99.99 inches

The scale converted to inches becomes 1 :100 inches.

The first number would be the size of the drawing, the second number is the size of the actual object

If you use all 4 scale factors for a real object that is 100 inches:

A would need 100/60 = 1.67 inches.

B would need 100/30 = 3.3 inches.

C would need 100/36 = 2.78 inches.

D would need 100/100 = 1 inch.

The larger scaled drawing would be B.

Answer:

Option B.

Step-by-step explanation:

We need to find which scale would produce the largest scale drawing of an object when compared to the actual object.

First of all cover all units in inches.

In option 1,

1 inch : 5 feet

We know that

1 feet = 12 inch → 5 feet = 60 inch

So the ratio in inches is 1:60. It means the scale factor is 60.

In option 2,

1 inch : 30 inches

So the ratio in inches is 1:30. It means the scale factor is 30.

In option 3,

1 foot : 12 yards

12 inches : 12 yards                     (1 feet = 12 inch)

1 inch : 1 yards

1 inch : 36 inch                     (1 yard = 36 inch)

So the ratio in inches is 1:36. It means the scale factor is 36.

In option 4,

1 centimeter : 1 meter

1 centimeter : 100 centimeter         (1 m = 100 cm)

1 inch : 100 inch

So the ratio in inches is 1:100. It means the scale factor is 100.

Option B has smallest scale factor, so it will produce the largest scale drawing of an object when compared to the actual object.

Therefore, the correct option is B.

Answer:  360

Step-by-step explanation:

LCM is least common multiple.  In other words, what number is divisible by 24, 36, and 60?

Factor each term.  See what they have in common and then multiply the common term by all of the leftovers.

                24                        36                         60

                 ∧                          ∧                           ∧

             12   2                    12  3                      12  5

They all have a 12 in common.  The leftovers are 2, 3, & 5.

So, the LCM is 12 × 2 × 3 × 5   = 360

Answer:$14.35

Step-by-step explanation:

The shop will charge $14.352 as markup price.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Cask’n’Cork wine shop that has a markup rate of 15%. A bottle of zinfandel wine costs $12.48 wholesale.

Assume that the shop charges $x. Then, we can write -

x = 12.48 + 15% of 12.48

x = 12.48 + (15/100) x 12.48

x = 12.48 + (3/20) x 12.48

x = 12.48 + 1.872

x = 14.352

Therefore, the shop will charge $14.352 as markup price.

Answer: Last option.

Step-by-step explanation:

In order to estimate the percent "n" of a number"x", you need easy numbers to work with, therefore you can round  "n" and "x" up or down; but it is important to remember that this estimation does not give you an exact value.

You can observe that Sergei's first step was to round 149% and 67 up, getting this result:

[tex]=105[/tex]

To verify if this estimate is less or greater than the actual answer, we can find the actual answer. This is:

[tex]\frac{67*149}{100}=99.83[/tex]

Therefore, we can conclude that the estimate is greater than the actual answer because the percent and the number were both rounded up.

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have a line that passes through the origin,

so

The graph shows a proportional relation ship

[tex]k=y/x[/tex]

For (1,3) ------> [tex]k=3/1=3[/tex]

For (2,6) ------> [tex]k=6/2=3[/tex]

For (3,9) ------> [tex]k=9/3=3[/tex]

The slope of the line is 3

Answer:

The slope of the line is 3.

Step-by-step explanation:

In the graph x-axis shows Pyramid Volume in cubic units and the y-axis shows Prism Volume in cubic units.

The line starts at (0, 0) and passes through (1, 3), (2, 6) and (3, 9).

If a line passes through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the slope of the line is

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Consider any two points of the line: (0, 0) and (1, 3). So, the slope of the given line is

[tex]m=\frac{3-0}{1-0}[/tex]

[tex]m=3[/tex]

Therefore, the slope of the line is 3.

A) The total for the plants she buys is 8.50, so the change in her checking account would be -8.50, because they will take 8.50 out of her account when the check is cashed, the amount in her account is lowered.

B) Mr. Clark's total is 11.25. If he pays with a 20, subtract the plant total from 20:

20 - 11.25 = 8.75 is the amount of change Jeremy owes him.

The amount of money Jeremy collects would be that amount higher than what he needs.

C)  Suzie owed 2.50, divide the amount she borrowed by the number of weeks her mom is keeping money:

2.50 / 5 = 0.50

Her allowance will be 0.50 less than what she normally would get.

D) Grandparents original amount = $15.00

3 daises = 3 x 3.75 = 11.25

1 geranium = 2.25

Total for new order = 11.25 + 2.25 = 13.50

Difference = 15 - 13.50 = 1.50

The new order would be $1.50 less.

E) Divide the total amount of the donation by the number of people:

14.40 / 3 = $4.80

F) Divide total amount by total people:
