Answer:

3

Step-by-step explanation:

if m is the number of months

Beckett: 90 + 25m

Lakota Hills 45 + 40m

so 90 + 25m = 45 + 40m

40m - 25 = 90 - 45

15m = 45

m = 45/15 = 3

A logarithm is a power that requires a number to be raised to another power. The bases of all the values involved must be identical. So, we must create equivalent expressions in the equation that all have equal bases. And the two expressions then formed can only be said equal if the exponents are also similar. Now we will move towards the solution to the problem.

Solution:

The correct answer is option (a) 70° is the possible measures of A.

Given that, the isoceles triangle's base angles are equal

let angle D be its vertical angle.

With angle E equal to angle F

angle D+ angle E+ angle F=180'

angle D+ 55'+55'=180',

angle D+ 110'=180'

angle D=180'-110'

angle D=70'.

Figure DEF is an isosceles triangle. The measure of A is 55°, while the measure of B is 70°. As there are two possible measures of D, it can be calculated that the base area equal to 426 square units and the height equals 232 square units.

Hence, 70° is the possible measures of A.

27.9 cm≤ perimeter ≤28.5cm

The length of the regular hexagon is 4.7cm to 1 decimal place, i.e.,

4.65≤ length≤4.75

As we know the number of sides of a regular hexagon is 6

So the perimeter for the upper bound of length = 6×4.65

                                                                                = 27.9cm

The lower bound of length perimeter = 6× 4.75

                                                              = 28.5cm

The total distance traveled by the pendulum when it comes to rest is 10,000 cm.

Because of friction and air resistance, each swing of a pendulum is a little shorter than the previous one. The lengths of the swings form a geometric sequence. Suppose the first swing of a pendulum has a length of 100 cm and the return swing is 99 cm .

Now,

Given,

On the first swing, the distance traveled is 100, and on the second swing, the distance is 99.

The first term of the geometric sequence is, a1 = 100

The second term of the sequence is, a2 = 99

The common ratio r = 99/100

Therefore, the expression for the n-t h term of the sequence is:

a_n = 100*(99/100)^(n-1)

Theoretically, using this formula, it would take an infinite number of trips to come to rest.

Hence we need to find the sum of the series a_n = 100*(99/100)^(n-1) from n=1 to n=infinity.

The sum of an infinite series is given by S = a/(1-r) where a=the first term and r=the common ratio.

Therefore,

the total distance traveled is S = 100/(1-(99/100) = 100/0.01 = 10,000 cm

Answer: give me the context please

Step-by-step explanation:

The eighth term of the given geometric sequence is 256/6561.

A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.

Given: 2/3, 4/9, 8/27...

As we can observe, each successive term of the geometric sequence is 2/3 of the previous one.

Thus, r = 2/3  and a₁ = 2/3.

The formula used to find the nth term of a geometric sequence is given by: [tex]a_n=a_1(r^{n-1})[/tex]

For n = 8, [tex]a_8=\frac{2}{3}(\frac{2}{3})^7=\frac{2}{3}^8=\frac{256}{6561}[/tex]

Thus, the eighth term of the given geometric sequence is 256/6561.

The equation is 24.36 = 5.31 + 5 * x  and the cost of each bag of lemon is $3.81

The given parameters are:

The above means that

Total = Cheese + Bags of lemon * 5

This gives

24.36 = 5.31 + 5 * x

Collect the like terms

So, we have

24.36  - 5.31 = 5 * x

Evaluate the like terms

So, we have

19.05 = 5 * x

Divide through by 5

So, we have

Classifying an equiangular triangle as an acute equiangular triangle is unnecessary because by definition, all angles are 60°

An equiangular triangle is one with three equal sides and three equal angles, all of which are measured at 60 degrees. Given that the characteristics of both triangles are the same, an equiangular triangle can also be referred to as an equilateral triangle.

This triangle is regarded as a regular polygon because its sides and angles are both equal. Equiangular refers to angles that are all equal.

All triangles have 3 angles that together total 180 degrees. Because an equilateral triangle has equal sides, its angles can only be 60 degrees. This entails that all angles must be acute. It is not required to write that it is intense because of this.

Inequality is [tex]p + 31 \ge 85[/tex]

Solution is [tex]p \ge 54[/tex]

===============================================

Explanation:

p = number of pages left to read

31 = number of pages already read

p+31 = total number of pages (unread + read)

This total must be 85 or larger, so that's how we end up with [tex]p+31 \ge 85[/tex]

To solve this inequality, we subtract 31 from both sides to end up with [tex]p \ge 54[/tex] which means Jen still needs to read at least 54 pages.

Answer: If (4, y ) is an ordered pair of the function, then y = 1

Step-by-step explanation:

The known x coordinate for the position (4,y) is 4.

We'll just refer to it as y since we don't know the y coordinate just yet.

On the x axis, trace a vertical line through 4 (see related remark below).

Thus in red (see attached image).

The red line crosses the graph at the point (4,1)

so this tells us that,

                                          y = 1

Although it's helpful to see how it turns out, you are not need to draw a vertical red line.

You will be able to visually perceive the solution without these extra lines after you become accustomed to these kinds of situations.

Therefore,

If (4, y ) is an ordered pair of the function, then y = 1

The slope of the given points are  (29, 11) and (-3, -7):

= 0.5625.

A line's slope indicates whether sharp it is.. The slope is defined mathematically as "climb overrun" (change in y divided by change in x).

In general, a line's slope indicates its steepness as well as direction. The slope of a straight line connecting two points (x1,y1) and (x2,y2) can be simply calculated by subtracting the coordinates of both the points. The slope is commonly denoted by the letter'm.'

X₁ = 29

Y₁ = 11
X₂ =  -3
Y₂ = -7

The slope is the degree of tilt a line has and it may be positive, negative, zero, or undefined.

slope = (y₂ - y₁) / (x₂ - x₁)

Substituting the value in the given formula:

slope  =  [tex]\frac{(-7 - 11)}{(-3 - 29)}[/tex]

          = -18 / -32

          = -9 / -16

Combinations:

Combinations are the way of selecting the objects or numbers from a group of objects or collection, and the order of the objects does not matter.
