Answer:

He must spend no more that 25 minutes practising scales.

Step-by-step explanation:

5t + 35 ≤ 60

5t ≤ 25

t ≤ 5.

So the maximum time for practising the scales is 5*5 = 25 minutes.

Answer:

Sven should spend 5 minutes or less on each scale. Maximum times is 25 minutes.

Step-by-step explanation:

Total time to practice piano = 60 minutes

He would like to spend at least 35 minutes playing songs instead of practicing scales.

Let t is the number of minutes he spends on each scale.

The time spend on 5 scales = 5t

Time for playing songs = 60 - 5t

It is given that he would like to spend at least 35 minutes playing songs instead of practicing scales.  It means time for playing songs is greater than or equal to 35.

[tex]60-5t\geq 35[/tex]

Subtract 60 from both sides.

[tex]60-5t-60\geq 35-60[/tex]

[tex]-5t\geq -25[/tex]

Divide both sides by -5. If an inequality is divided or multiplied by a negative number, then the sign of inequality is changed.

[tex]t\leq 5[/tex]

Sven should spend 5 minutes or less on each scale.

The maximum value of t is 5, so the maximum time spend on practicing scales is

[tex]\text{Maximum time}=5t\Rightarrow 5(5)=25[/tex]

Therefore, the maximum time is 25 minutes.

Final answer:

To find the unit price of markers in a set, divide the total cost by the number of markers to find that each marker costs $0.30 when 20 are purchased for $6.

Explanation:

Lainey's purchase of a set of 20 markers for $6 can be used to illustrate a simple mathematical concept known as unit price, which is the cost per individual item when items are sold in a set or batch. To calculate the unit price, you divide the total cost by the number of items in the set. Here's how you can do this calculation:

Determine the total cost of the set of markers, which is $6.

Count the number of markers in the set, which is 20.

Divide the total cost by the number of markers to find the unit price: $6 ÷ 20 = $0.30 per marker.

Therefore, the cost of each individual marker from the set is $0.30. Starting small, such as with markers, pencils, sharpeners, and erasers, and gradually adding other items like construction paper or magnets, are good practices in both purchasing supplies and understanding incremental costs in financial literacy.

Move n terms on one side and other terms on the other side. Note that by moving we are essentially subtracting and adding to both sides so the prefix of a term changes from - to + or from + to -.

Answer:

Discount = $10

Sales Price = $30

Step-by-step explanation:

Discount

= 25% of marked price

= 25% x $40

= (25/100) x 40

= $10  

Sales price = Marked price - Discount = $40 - $10 = $30

Answer:

60$

Step-by-step explanation:

if 4$ is per year 20 ÷4 is 5, 5 years have passed and if 10 uears after the champion ship it will be 60 because 4 × 10 is 40 plus the 5 years since it was 20 therefore 20+40 =60

The explicit formula for the ticket price after n years is T(n) = 20 + 4n. Plugging in 10 for n, we find that the price 10 years after the championship will be $60.

The question asks us to create an explicit formula to model the increasing price of football tickets after the local team won a championship. If tickets were originally $20 and the price increases by $4 each year, we can use the formula T(n) = 20 + 4n to represent the price of football tickets after n years.

For 10 years after the championship year, we plug 10 into our equation for n: T(10) = 20 + (4 \times 10) = 20 + 40 = $60. Thus, the ticket price will be $60, 10 years after the championship year.

Step-by-step explanation:

[tex]\begin{array}{rcl}\\\text{Number of tons} & = & \text{Number of trips} \times \dfrac{\text{number of tons}}{\text{1 trip}}\\\text{3.75 t} & = & \text{Number of trips}\times \dfrac{\text{1.5 t}}{\text{1 trip}}\\\dfrac{3.75}{1.5} & = & \text{Number of trips}\\\text{Number of trips} & = & 2.5\\\end{array}[/tex]

Jason can't make 2.5 trips.

He can make two trips carrying a full load and another trip carrying a half-load.

That makes three trips.

Answer:

B. 108 calories

Step-by-step explanation:

The mean number of a data set is

[tex]\text{Mean}=\dfrac{\text{The sum of all calories in products}}{\text{The number of products}}[/tex]

Corn chips: 230 calories

Popcorn: 25 calories

Potato chips: 115 calories

Pretzels: 62 calories

Thus,

The sum of all calories [tex]=230+25+115+62=432[/tex]

The number of productrs = 4

The mean number of calories [tex]=\dfrac{432}{4}=108[/tex]

To fill the tank, multiply 2/5 by the tank's capacity of 20.25 gallons.

To find the number of gallons it will take to fill the tank, we need to determine how much more fuel is needed to make the tank full. We can do this by subtracting the current amount of fuel in the tank from its full capacity. The tank is 3/5 full, so the remaining amount of fuel needed to fill the tank is 2/5 of its capacity. Since the capacity of the tank is given as 20.25 gallons, we can calculate the number of gallons needed to fill the tank by multiplying 2/5 by 20.25:

2/5 * 20.25 = 8.1 gallons

Therefore, it will take 8.1 gallons to fill the tank.

[tex]\frac{1}{2}\times \text{Boundary of county Harding touching Adams}\times \text{Boundary of county Lincoln touching Adams}[/tex]

Step-by-step explanation:

In the figure attached, map shows the dimensions of the 5 counties in a Midwestern state.

Adams county has the triangular boundaries.

Since area of triangle is represented by the expression [tex]\frac{1}{2}(\text{Base})\times (\text{Height})[/tex]

Base represents the boundary of county Harding touching Adams = 18 mi.

Height represents the boundary of county Lincoln touching Adams = 10 mi

Therefore, expression representing the area of Adams county will be

Answer:

The possible values of the perimeter of the rectangle is between 18 and

18.4 cm ⇒ [18 < perimeter of rectangle < 18.4] cm

Step-by-step explanation:

* Lets explain how to solve the problem

- The perimeter of any quadrilateral is the sum of the length of its

  four sides

- The rectangle is a quadrilateral with each two opposite sides are

  equal in lengths, then its perimeter = 2l + 2w, where l, w are its

  length and width

∵ The the length of the rectangle is a

∵ 5.4 < a < 5.5 cm

∵ The perimeter of the rectangle = 2a + 2b

- Lets multiply the inequality by 2

∴ 5.4 × 2 < a × 2 < 5.5 × 2

∴ 10.8 < 2a < 11 ⇒ (1)

∵ The width of the rectangle is b

∵ 3.6 < b < 3.7 cm

- Lets multiply the inequality by 2

∴ 3.6 × 2 < b × 2 < 3.7 × 2

∴ 7.2 < 2b < 7.4 ⇒ (2)

- Add inequalities (1) and (2)

∵     10.8 < 2a < 11

  +   7.2 < 2b < 7.4

∴  18 < 2a + 2b < 18.4

∵ 2a + 2b represents the perimeter of the rectangle

∴ The possible values of the perimeter of the rectangle is between

  18 and 18.4 cm ⇒ [18 < perimeter of rectangle < 18.4] cm

hope it helps :)

Answer:

Step-by-step explanation:

N is between points M and O

MN = x

MO = 3x - 6

NO = x + 1

The way it reads MN + NO = MO

x + x + 1 = 3x - 6

2x + 1 = 3x - 6

2x - 2x +1 = 3x -2x - 6

1 = x - 6          

1 + 6 = x

x = 7

MO = 3x - 6

MO = 3*7 - 6

MO = 21 - 6

MO = 15

The numerical length of MO, given MN = x, MO = 3x - 6, and NO = x + 1, is 15.

Given the conditions of the problem, we can create the equation MO = MN + NO based on segment addition postulate in Geometry. This implies: 3x - 6 = x + x + 1, or 3x - 6 = 2x + 1. Solving this equation for x, you get x equals 7. Substituting x = 7 into MO = 3x - 6 gives you: MO = 3(7) - 6 = 21 - 6 = 15. So, the numerical length of MO,  given MN = x, MO = 3x - 6, and NO = x + 1, is 15.

Final answer:

An expression for a number that's twice another number represented by n is written as 2n.

Explanation:

If n represents a number, then the expression for a number that's twice n can be written as 2n. This stems from the definition that multiplying a number by 2 effectively doubles it. To better understand this concept, consider the next statement, N=N*2, which tells us that the new value of N is twice the original value. So, if we substitute N with n, we can express a number that's twice n as 2n.
