Answer: THE ANSWER TO THAT IS C
Step-by-step explanation:
Find the length of side x in simplest radical form with a rational denominator
Length of the side, x = 11/2
radical form, x = √5.5
Define Hypotenuse.The longest side of a right-angled triangle which is the side opposite to the right angle is called hypotenuse. The hypotenuse can be easily found using the Pythagorean theorem. It states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
As given in question, ∅ = 60°,
Using, Cos ∅ = adjacent/hypotenuse :
Cos 60°= x/11
As we know cos 60° = 1/2
1/2 = x/11
x, length of the side = 11/2= 5.5
radical form = 5.5

The number of hours needed to paint a house, h, varies inversely with the number of painters, n. Four painters need 6 hours to paint a house. Find the equation represents this relationship.
The equation that represents this relationship is h*n = 24.
How do we solve linear equations?
First order equations include all linear equations as a subset. In the coordinate system, lines are defined as having linear equations. A linear equation in one variable is made up of one homogeneous variable of degree one (i.e., only one variable). A linear equation could contain multiple variables. When a linear equation comprises two variables, for instance, linear equations in two variables are utilized. A mathematical statement known as an equation contains an algebraic expression and the equal symbol (=). It is the equation for a straight line. The equation is shown to be valid when values are substituted for the unknown values in the solutions of linear equations. When there is just one variable, there is just one answer.
Given, number of hours needed to paint a house = h
Number of painters needed to paint the house = n
Also, the relation between h and n is inverse, thus:
h*n = k, where k is the proportionality constant.
Therefore, initial equation derived is h*n = k --(i)
Putting h = 6 and n =4 in (i), we can get the value of k as
k = h*n = 6*4 = 24 --(ii)
Comparing (i) and (ii), we get,
h*n = 24, which is the required equation.

The average temperature of all the given days is 19/7˚C or 2.7˚C
The average temperature of all the given days is -19/7˚C or -2.7˚C
The average temperature of all the given days is 61/7˚C or 8.7˚C
The average temperature of all the given days is -61/7˚C or -8.7˚C
Answer: Choice A) The average temp is 19/7 or 2.7 degrees Celsius
=======================================================
Explanation:
Ignore the ˚C and focus on the numbers only
We have this set of values
15, 1, -4, 3, -10, -7, 21
Add them up to get
15+1+(-4)+3+(-10)+(-7)+21 = 19
Then divide that sum over the total number of items in the set, which in this case is 7.
That's how we get to 19/7 which approximates to 2.7 when rounding to one decimal place.

For each of the professions in the left column, calculate the annual pay based on full-time, year-round employment consisting of 2,000 hours a year (40 hours per week for 50 weeks per year). Record your calculations under "Annual income" in the table. Then, find the difference between each annual wage figure and a) the poverty threshold and b) the median household income. If the difference is a negative number, record it as such.
The difference between each annual wage figure and the poverty threshold is as shown in the attached completed table.
How to calculate Annual Income?
Annual Income is a term in economics that is calculated by multiplying the Hourly wage by 4,000 hours.
Now, the Difference between annual wage and the federal poverty line is calculated by subtracting the 2019 Poverty threshold of $13,011 from the Annual Income.
The Difference between annual wage and median household income is calculated by deducting the 2019 Median household income of $68,703 from the Annual income. Negative balances are highlighted.

A trapezoid has coordinates F (−9, 6), G (−6, 9), H (−3, 9), and I (0, 6).
a. Dilate the trapezoid by a scale factor of 1/3 with a center of dilation at the origin.
b. Is the dilation a reduction or an enlargement? Explain your reasoning.
a) the coordinates of the dilated trapezoid is F'(-3, 2), G'(-2, 3), H'(-1, 3), I'(0, 2)
b) Dilation is reduction.
In this question, we have been given a trapezoid has coordinates F (−9, 6), G (−6, 9), H (−3, 9), and I (0, 6).
a. We need to dilate the trapezoid by a scale factor of 1/3 with a center of dilation at the origin.
The scale factor is 1/3
so, the coordinates of the image would be,
F' = 1/3 (-9, 6)
= (-3, 2),
G' = 1/3(-6, 9)
= (-2, 3),
H' = 1/3 (−3, 9)
= (-1, 3),
and I' = 1/3 (0, 6)
= (0, 2)
b. We know that a dilation is a geometric transformation that either enlarges or reduces a figure in size.
As we know, if the scale factor is between 0 to 1 then the image is reduction and if the scale factor is greater than 1 then the image is enlargement.
Here, scale factor is 1/3 which is 0 < 1/3 < 1
So, in this case the dilation is reduction.
Therefore, a) the coordinates of the dilated trapezoid is F'(-3, 2), G'(-2, 3), H'(-1, 3), I'(0, 2)
b) Dilation is reduction.

The rate at which a population of bacteria grows is proportional to the size of the population. At 1:00 PM, the population of a certain strain of bacteria was 5,400. At 1:20 PM, the population was 9,000. At what time will the population of bacteria be 25,000?
The time at which the population of bacteria will be 25,000 is 2:49 pm.
Given that:-
Population of bacteria at 1:00 PM = 5,400
Population of bacteria at 1:20 PM = 9,000
The rate at which a population of bacteria grows is proportional to the size of the population.
We have to find the time at which the population of bacteria will be 25,000.
The rate at which population of bacteria grows = 3600 bacteria/ 20 min = 180 bacteria/min
Let the population of bacteria takes t minutes to become 25,000.
Hence, we can write,
5400 + 180t = 25000
180t = 25000 - 5400
180t = 19600
t = 19600/180

We can define the translation of building from location C to location E by the following rule -
(x, y) → (x - 4 , y + 6)
What is translation of graph?
A translation is a movement of the graph either horizontally (parallel to the x -axis) or vertically (parallel to the y -axis) without changing its orientation.
Given is a Building C translated to Building E.
In order to translate the building from location C to location E, we will first shift the building near the x - axis vertically upwards. For this we will shift the y coordinate by -
- 7 + y[s] = - 1
y[s] = -1 + 7
y[s] = 6
So the y - coordinate of the translated graph will be -
(y + 6)
Now, we will shift the x coordinate -
1 + x[s] = -3
x[s] = -3 - 1
x[s] = -4
So the x - coordinate of the translated graph will be -
(x - 4)
Therefore, we can define the translation by the following rule -
(x, y) → (x - 4 , y + 6)
