To rent a certain meeting room, a college charges a reservation fee of $19 and an additional fee of $4 per hour. The chemistry club wants to spend at most $59 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room? Use t for the number of hours. Write your answer as an inequality solved for t.
The set of numbers which represents the possible number of hours for which the chemistry club could rent the meeting room is; t <= 10 hours.
What is the possible number of hours for which the chemistry club could rent the meeting room?It follows from the task content that the possible number of hours for which the chemistry club could rent the meeting room is to be determined.
Since the linear inequality which represents the situation in discuss can be written as follows;
4(t) +19 <= 59
where t = number of hours.
Solving the inequality, we have;
4t <= 59 - 19
4t <= 40
t <= 10 hours.
Ultimately, The set of numbers which represents the possible number of hours for which the chemistry club could rent the meeting room is; t <= 10 hours.

For what value of k will the three points (1,8), (2,11), and (3,k) be on the same line?
The value of k for which the three points (1,8), (2,11), and (3,k) be on the same line will be on the same line is 14.
What is a slope ?The slope is the rate of change.It can also be defined as the rise over run.
According to the given question for what value of k will the three points (1,8), (2,11), and (3,k) be on the same line.
If three three points are on the same line they are co-linear and the slope of the points (1,8), (2,11) and (2,11), (3,k) will be same.
∴ (11-8)/(2-1) = (k-11)/(3/2)
11-8 = k - 11
k = 11 + 11 - 8
k = 22 - 8
k = 14.

what is unique about the plants that grow in the Mediterranean brush?
Step-by-step explanation:
The Mediterranean vegetation is dominated by evergreen shrubs and sclerophyllous trees adapted to the distinctive climatic regime of summer drought and cool moist winters with only sporadic frost.
Given the following formula, solve for a.
s=a+b+c/2
We can rearrange it to the standard form perimeter a = s - b - C/2
In arithmetic, what is a perimeter?
The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.
The answer to your question is a = s - b - C/2
To solve for "a", we must get "a" on it's own side of the equal sign. We can first subtract "s" from both sides:
0 = a + b + C/2 - s
Then, we can subtract a from both sides:
-a = b + C/2 - s
Finally, we divide both sides by -1, so a is by itself.
a = -b - C/2 + s
And we can rearrange it to the standard form:
a = s - b - C/2

write the equation of the line in slope-intercept from that passes through the given points. (3/8, 0)and (5/8, 1/2)
The equation of line slope-intercept from is obtained as y = 2x - 3/4.
What is defined as the slope-intercept from?An intercept is a y-axis point whereby the slope of a line passes. It is the y-coordinate of a point on the y-axis in which a straight line or a curve intersects. This is represented by the equation for a straight line, y = mx + c, in which m is the slope as well as c is the y-intercept.The slope of the line is calculated by the formula;
m = (y₂ - y₁)(x₂ - x₁)
The coordinates of points are-
Where, (x₁, y₁) = (3/8, 0), and
(x₂, y₂) = (5/8, 1/2)
Put the values in slope;
m = (1/2 - 0)/(5/8 - 3/8)
m = (1/2)/(2/8)
m = 2
Put the the values in the standard form of equation;
(y - y₁) = m(x -x₁)
(y - 0) = 2(x - 3/8)
Simplifying;
y = 2x - 3/4
Thus, the equation of line slope-intercept from is obtained as y = 2x - 3/4.

use pescals triangle to completely expand (3x-1)^4

This is further explained below.
What is Pascal's Triangle of (3 x-1)^4?Generally, the equation for the expansion is mathematically given as
(3 x-1)^4
Pascal's Triangle can be displayed as such:
1
1-1
1-2-1
1-3-3-1
1-4-6-4-1
The triangle can be used to calculate the coefficients of the expansion of (a+b)^n by taking the exponent n and adding 1 .
The coefficients will correspond with line n+1 of the triangle.
For (3 x-1)^4, n=4 so the coefficients of the expansion will correspond with line 5.
The expansion follows the rule
(a+b)^n=c_0 a^n b^0+c_1 a^{n-1} b^1+c_{n-1} a^1 b^{n-1}+c_n a^0 b^n
The values of the coefficients, from the triangle, are $-4-6-4-1.

You can buy a property today for $3.7 million and sell it in 6 years for $4.7 million. (You earn no rental income on the property.) a. If the interest rate is 6%, what is the present value of the sales price? Note: Do not round intermediate calculations. Enter your answer in millions rounded to 3 decimal places. b. Is the property investment attractive to you? c-1. What is the present value of the future cash flows if you also could earn $270,000 per-year rent on the property? The rent is paid at the end of each year. Note: Do not round intermediate calculations. Enter your answer in millions rounded to 3 decimal places. c-2. Is the property investment attractive to you now?
Based on the selling price of the property in 6 years, the present value of the selling price is $3,313,315.
This amount is NOT attractive.
Based on the annual cash flows from the property, the present value of the cash flows is $4,640,991.40.
The property will then be attractive
What is the present value?The present value of the selling price can be found as:
= Selling price / (1 + rate) ^ number of years
= 4,700,000 / (1 + 6%)⁶
= $3,313,315
This amount is less than the buying price of the property today so the property is not attractive as it would result in a present value loss.
The present value of the cashflows will be the present value of an annuity because the rent is constant:
= Rent value x Present value interest factor of an annuity, 6 years, 6%
= 270,000 x 4.91732
= $1,327,676.40
The present value of the property then becomes:
= 1,327,676.40 + 3,313,315
= $4,640,991.40
The property then becomes very attractive because the present value gives a gain over the selling price of $3.7 million.
