Answer:

(10+t)*25

Step-by-step explanation:

25 students so the cost for 1 student needs to be multiplied by 25 for all the students

If lunch costs $10 by itself not including the ticket, we don't know how much the ticket costs so lets say ticket cost = t

$10+t = the cost for ONE student

but there are 25 students so, ($10+t)*25 could work

Expressions don't have equal signs so the total is  (10+t)*25

Using logarithmic quotient and power rule, we expand each logarithm function log (2√x/5)³ as  3. log (2√x) - log (5).

According to the question, we need to expand  we expand logarithm function log (2√x/5)³.In Logarithms, the power is raised to some numbers (usually, base number) to get some other number. It is an inverse function of exponential function.

Power rule for logarithm: log (a)ˣ = x log (a)

Quotient rule for logarithm: log (a/b) = log (a) - log(b).

⇒log (2√x/5)³

Applying power rule to the above logarithm function, we get

log (2√x/5)³ = 3. log (2√x/5)    →(1)

Applying quotient rule to the equation (1), we get

3. log (2√x/5)  = 3. log (2√x) - log (5)

Hence, using logarithmic quotient and power rule, we expand each logarithm function log (2√x/5)³ as  3. log (2√x) - log (5).

Answer:

  a. P = 190t -373,930 . . . . . t=actual year number

  b. P = 6640

Step-by-step explanation:

Given the two points (1991, 4360) and (1999, 5880) on a linear relation between years and moose population, you want a formula for the population (P) and an estimate of the population in 2003.

We can use the point-slope form of the equation for a line to write the formula for moose population. To do that, we need to know the slope of the line.

The slope is given by the formula ...

  m = (y2 -y1)/(x2 -x1) . . . . . . . . line through points (x1, y1) and (x2, y2)

Using the given point values, we have ...

  m = (5880 -4360)/(1999 -1991) = 1520/8 = 190

The point-slope equation for a line with slope m through point (h, k) is ...

  y -k = m(x -h)

Using the first ordered pair, we can write the equation as ...

  y -4360 = 190(x -1991)

  y = 190x -373,930 . . . . . . . where x is the actual year number

Using P and t for the variables, the formula is ...

  P = 190t -373,930

Using t=2003, the above formula evaluates to ...

  P = 190(2003) -373,930 = 380,570 -373,930

  P = 6,640

The linear model predicts the 2003 population to be 6640 moose.

__

Additional comment

The formula above uses actual year number. The year value can be translated any way you might want. For example, using t = years after 1991, the formula would be ...

  P = 190(t +1991) -373,930

  P = 190t +4360

Then t=12 for year 2003.

The simplest ratio of squares to total shapes will be 2:7.

A ratio in mathematics shows how many times one number is contained in another. When two objects are related using numbers or amounts, the relationship is known as a ratio. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).

A ratio can have any number of quantities, such as counts of people or things or measurements of length, weight, time, etc. Both numbers must be positive in most situations. From the information, there are 4 squares as 10 triangles.

Therefore, the simplest ratio of squares to total shapes will be:

Number of squares = 4

Total shapes = 4 + 10 = 14

Ratio = 4 / 14

Ratio = 2/7

Therefore, the simplest ratio of squares to total shapes will be 2:7.

Rearrange the Fraction in the order of least to largest:

A fraction is a portion of a larger total. The number is expressed in arithmetic as a quotient, which is the numerator divided by the denominator. Both are integers in a simple fraction. A complicated fraction contains a fraction in either the numerator or the denominator.

Fractions are significant because they indicate what percentage of a whole you require, have, or desire. In baking, fractions are used to indicate how much of an ingredient to use.

Fractions are a vital basis for studying more advanced math's. As a student's first introduction to abstraction in mathematics, fractions give the greatest foundation for algebra.

The required expression or inequality for possible widths of the rectangle is -4 < x < 3.

Given:

A rectangle has a length 6 meters more than six times the  width.

The area of the rectangle is less than 72 meters  squared.

We have to find,

The expression or inequality that represents all possible  widths of the rectangle.

Let x be the width of the rectangle.

Length of the rectangle is 6 meters more than six times the  width.

length = 6x + 6

Area of rectangle is:

Area = length × width

Area = (6x + 6) × x

Area = 6x² + 6x

The area of the rectangle is less than 72 meters  squared.

6x² + 6x < 72

6x² + 6x -72 < 0

Divide both sides by 6.

x² + x - 12 < 0

x² + 4x - 3x - 12 < 0

x(x + 4) - 3(x + 4) < 0

(x + 4) (x - 3) < 0

It is true if one factor is negative and other is positive. So,

x - 3 < 0 ⇒ x < 3  ...(i)

x + 4 > 0 ⇒ x > -4  ...(ii)

Using (i) and (ii), we get

-4 < x < 3

Therefore, the required expression or inequality for possible widths of the rectangle is -4 < x < 3.

The greatest integer that is less than the value of the logarithm log17.52 is 1.

We are required to check the value of greatest integer that is less than log17.52

As no base is mentioned, let us consider the base to be 10

Thus, we are required to find the value of log₁₀17.52

log₁₀17.52=log₁₀10+log₁₀7.52

log₁₀10=1

log₁₀7.52=log₁₀752/log₁₀100

                =log₁₀752-2log₁₀10

                = 2.876-2=0.876

Thus, log₁₀17.52=1+0.876 =1.876

Thus , log₁₀17.52 is 1.876

Therefore, The greatest integer that is less than the value of the logarithm log17.52 is 1

Since no base has been provided for the logarithm, 10 has been considered to be the base.

Step-by-step explanation:

so first just think about the question 7(x + 5)

Based on the formulas given for PR and QR, the length of PR is 19.8 units.

The shape that is given is an equilateral triangle. What this means is that all the sides of the triangle are equal.

This means that PR and QR are therefore equal:

PR = QR

This can help us to find the value of n by equating both formulas:

2n + 9 = 7n - 18

The value of n can then be found as:

7n - 2n = 18 + 9

5n = 27

n = 5.4

The length of PR can then be solved by substituting n into the formula:

= 2n + 9

= 2 (5.4) + 9
