Hannah wants to install a wallpaper border around the perimeter of her
bedroom.
the floor area of her bedroom is 361 m2.
she has 72 m of wallpaper.
does she have enough wallpaper? how do you know?
need this for tomorrow <\3
Answers
The perimeter of the bedroom is 76 meters.
Hannah will need to obtain additional wallpaper to cover the entire perimeter.
To determine if Hannah has enough wallpaper to install a border around the perimeter of her bedroom, we need to calculate the perimeter of the room and compare it to the length of the wallpaper she has.
First, let's find the dimensions of the bedroom since we know its floor area. Since the bedroom is most likely rectangular, we can find the dimensions by taking the square root of the floor area:
√361 m² = 19 m
Now, let's calculate the perimeter of the bedroom. The perimeter of a rectangle is given by the formula: P = 2 * (length + width)
In this case, since the bedroom is rectangular, we can assume one side is the length and the other side is the width:
P = 2 * (19 m + 19 m) = 2 * 38 m = 76 m
So, the perimeter of the bedroom is 76 meters.
Hannah has 72 meters of wallpaper, which is less than the perimeter of the room. Therefore, she does not have enough wallpaper to install a border around the entire perimeter of her bedroom.
Unfortunately, Hannah will need to obtain additional wallpaper to cover the entire perimeter.

Answer:
\(x=9\)
Step-by-step explanation:
ABC is the sum of the angles CBD and ABD. So:
\(\angle ABC=\angle CBD+\angle ABD\)
Substitute them for their equations:
\((-7x+241)=(-4x+123)+(154-7x)\)
Solve for x. Combine like terms on the right:
\(-7x+241=-11x+277\)
Add 11x to both sides:
\(4x+241=277\)
Subtract 241 from both sides:
\(4x=36\)
Divide both sides by 4:
\(x=9\)
The value of x is 9.

Find the difference in the given lengths of the polygons . (7x + 2) units (6x - 5) units .
Answers
Answer:
Difference in the lengths of the polygons is (x + 7) units.
Step-by-step explanation:
Lengths of the given polygon = (7x + 2) units and (6x - 5) units
Therefore, difference in the given lengths = (7x + 2) - (6x - 5)
= (7x - 6x) + (2 + 5)
= x + 7
Therefore, difference in the lengths of the polygons is (x + 7) units.

Given is the graph of a straight line as shown.
The general equation of a straight line equation is given by : y = mx + c.
The y - intercept is given by -
[c] = 3 (0, 3)
The line passes through the points -

Geoff Poshingten is out at a fancy pizza joint, and decides to order a calzone. When the waiter asks what he would like in it, he replies, "I want either pepperoni or sausage. Also, if I have sausage, then I must also include quail. Oh, and if I have pepperoni or quail then I must also have ricotta cheese. "
A. Translate Geoff's order into logical symbols.
B. The waiter knows that Geoff is either a liar or a truth-teller (so either everything he says is false, or everything is true). Which is it?
C. What, if anything, can the waiter conclude about the ingredients in Geoff's desired calzone?
Answers
1 ) P be Pepperoni, Q be Quail, R be Ricotta cheese, S be Sausage.
To translate Geoff's order using Discrete Math,
I want either pepperoni or sausage = P or S = (P ∨ S)If I have sausage, then I must also include quail = S→QIf I have pepperoni or quail then I must also have ricotta = (P∨Q)→R2 ) Geoff is a truth-teller. Based on his last statement, where ricotta (R) is implied from pepperoni (P) or quail (Q) , we would have no way of knowing if R is true/false if (P or Q) was false- so, R must be true if (P or Q) is false because of the whole “innocent until proven guilty” thing. therefore, since a lie in P or Q would lead to truth, Geoff must be a truth-teller because he can’t tell all lies.
Using this information, that Geoff always tells the truth.
For the third statement, if Geoff is lying then the truth is "I must have pepperoni or quail and I cannot have ricotta cheese."
~[(P ∨ Q) → R] = [(P v Q) ∧ ~R)]
Or in more general terms, ~(a → b) = (a ∧ ~b)
Which, gives us (a → b) = (~a ∨ b)
Anyhow, even if Geoff tells all lies, there is a valid statement that can be made: Pepperoni and sausage, no quail, no ricotta.
Also, if Geoff tells the truth, there's nothing that says he can't have quail with pepperoni: pepperoni, quail, and ricotta is also valid.

Determine the WVC on for each day presented below. Day 1: Air Temperature= 86°F and RH= 60% Day 2: Air Temperature= 41°F and RH=90% At what point during the day would you expect outside relative humidity values to be the lowest? …to be the highest? Explain/justify your response.
Answers
Relative humidity tends to be highest during the early morning hours, shortly before sunrise.
To determine the Wet-Bulb Temperature (WBT) and Wet-Bulb Depression (WBD), we need the dry-bulb temperature (DBT) and relative humidity (RH) values.
The Wet-Bulb Temperature (WBT) is the lowest temperature that can be achieved by evaporating water into the air at constant pressure, while the Wet-Bulb Depression (WBD) is the difference between the dry-bulb temperature (DBT) and the wet-bulb temperature (WBT). These values are useful in determining the potential for evaporative cooling and assessing heat stress conditions.
Day 1: Air Temperature= 86°F and RH= 60%
To calculate the WBT and WBD for Day 1, we would need additional information such as the barometric pressure or the dew point temperature. Without these values, we cannot determine the specific WBT or WBD for this day.
Day 2: Air Temperature= 41°F and RH= 90%
Similarly, without the necessary additional information, we cannot calculate the WBT or WBD for Day 2.
Regarding your question about the point during the day with the lowest and highest outside relative humidity values, it is generally observed that the relative humidity tends to be highest during the early morning hours, shortly before sunrise. This is because the air temperature often reaches its lowest point overnight, and as the air cools, its capacity to hold moisture decreases, leading to higher relative humidity values.
Conversely, the outside relative humidity tends to be lowest during the late afternoon, typically around the hottest time of the day. As the air temperature rises, its capacity to hold moisture increases, resulting in lower relative humidity values.
It's important to note that these patterns can vary depending on the local climate, weather conditions, and geographical location. Other factors such as wind patterns and nearby bodies of water can also influence relative humidity throughout the day.

what is slope ?The steepness of a line determines its slopes. "Gradient overflows" is the name of a contour mathematical equation (the change in y divided by the change in x). The inclination is the ratio of such vertical (rise) to the horizontal (run) change in level between any two places. The gradient form of an answer is used to illustrate a straight line when its equation is represented as y = mx + b. The y-intercept is situated where the slope of the line is m, b is b, and (0, b). For instance, considering como and slope of the eqs y = 3x - 7 (0, 7). The line has a slope of m, a b quantity at the y-intercept, and (0, b). As
given
The graph's slope and speed are as follows:
Slope = 60
Speed is 60 mph.
The ratio of the ascent to the run is the line's slope.
Rise is equal to y2 - y1 = (120 - 60) = 60.
Run = x2 - x1 = (2 - 1) = 1
The incline is equal to (Rise / Run) = (60 / 1) = 60.
The slope indicates that the bus will travel 60 miles per hour throughout the journey.
The distance traveled per hour is the speed.
You can compute the speed as follows:

What is public debt?Government obligations, particularly those evidenced by securities, to pay certain sums to holders at some future time. Private debt, which includes the obligations of individuals, businesses, and nongovernmental organizations, is distinct from public debt. A debt-to-GDP ratio compares a country's total debt to its economic productivity. Divide a country's debt by its GDP to calculate the debt-to-GDP ratio. Governments can use public debt to raise funds to expand their economies or pay for services. Politicians would rather increase the national debt than raise taxes.

Step-by-step explanation:
Use the rules of indices to find the product.
One of the rules is that when we multiply indices that have the same base we add the powers. For example:
\(x^4 * x^5 = x^9\)
So to work out \(a^4(3a^2-2a+1)\) we need to follow this rule.
Let's expand the bracket:
\(a^4(3a^2-2a+1) = (a^4)(3a^2)+(a^4)(-2a)+(a^4)(1)\)
Let's simplify keeping in mind the rule we know.
\((a^4)(3a^2)=3a^6\)
\((a^4)(-2a) = -2a^5\) - remember that \(a = a^1\)

Answers
The apothem of the regular heptagon is 13.49 feet.
To find the apothem of a standard heptagon with side length 13 ft and region 614.25 ft, we can utilize the recipe:
The formula for determining the heptagon's perimeter is: Area = (1/2) Perimeter Apothem Since we already know the side length and the area,
Edge = 7 × Side Length
Connecting the given qualities, we get:
Now that we know the perimeter and area of the apothecary, we can enter them into the formula:
614.25 ft = (1/2) × 91 ft × Apothem
Addressing for the apothem, we get:
Apothem = (2 × 614.25 ft)/(91 ft) = 13.49 ft (adjusted to the closest 100th)
In this way, the apothem of the customary heptagon is 13.49 feet.
