If Angle A is acute and Angle B is obtuse and Angle A is 2X+5 and Angle B is 6X+55, then how many degrees would Angle A be?
Angle A is 35° and Angle B is 145°
Supplementary angles are angles that give 180° when added together
Angle A and Angle B are supplementary angles such that
∠A + ∠B = 180°
Given that ∠A is acute angle and ∠B is obtuse angle
also , ∠A = 2x+5 and ∠B = 6x+55
using supplementary angle property ,
2x+5 + 6x+55 = 180
solving for x ,
8x + 60 = 180
x = 15
8x = 180 - 60
8x = 120
∠A = 2x+5
substituting value of x
∠A = 2(15)+ 5 = 30+5
∠A = 35°

If a different number in domain of a function have different outputs the function is called?
A function is a rule that assigns each input exactly one output. We call the output the image of the input. The set of all inputs for a function is called the domain.
A function is one-to-one if no two elements in the domain correspond to the same element in the range.
Thus, if a different number in the domain of a function has different outputs the function is called a one-to-one function

On a certain day the probability of rain is 80% probability of thunder is 3/5 and the probability of both is 2/5. What is the probability that it will rain or thunder?
The probability it will rain or thunder = 100%
Explanation:Probability it will rain = 80%
P(rain) = 4/5 (simplest term in fraction)
Probability of thunder = 3/5
P(thunder) = 3/5
Probability of both rain and thunder = 2/5
P(rain and thunder) = 2/5
We need to find the probability of rain or thinder = P(rain or thunder)
To find the probability of P(rain or thunder), we will apply the formula for the addition rule on any two events:
[tex]P(A\text{ or B\rparen = P\lparen A\rparen +}P(B)\text{ - P\lparen A and B\rparen}[/tex]Applying the formula in our question:

[tex]\begin{gathered} P(rain\text{ or thunder\rparen = }\frac{4}{5}\text{ + }\frac{3}{5}-\text{ }\frac{2}{5} \\ \\ P(rain\text{ or thunder\rparen = }\frac{4\text{ + 3 - 2}}{5} \\ P(rain\text{ or thunder\rparen = }\frac{5}{5} \\ \\ P(rain\text{ or thunder\rparen = 1} \end{gathered}[/tex]In percentage, the probability it will rain or thunder = 100%

a debt company wants to build a uniquely shaped decks how many square feet of wood will the company need to cover the deck designer below shaped like a regular pentagon a trapezoid the height of the trapezoid is 4.5 ft round your answer to one decimal place to find the area of the Pentagon divided into 5 similar triangles you see if I could the radius at the Pentagon the distance from each vertex Center is 4.25 ft
72.2 square feet of wood will the company need to cover the deck designer shaped like a regular pentagon and a trapezoid.
To find the total wood required we need to add the area of pentagon and area of trapezoid.
Firstly we will draw the 5 similar triangle in the pentagon as shown below:
Lets name one triangle as ABC.
Given, radius of pentagon = 4.25 ft. (Let x)
Now, in triangle ABC,
BD=DC=2.5 ft. (half of the BC)
By applying Pythagoras theorem,
[tex]AB^{2} =AD^{2} +BD^{2} \\AD=\sqrt{AB^{2} -BD^{2} } \\AD=\sqrt{11.81} \\AD=3.44 ft.[/tex]
We know that AD is the height of triangle ABC.
So, Height = AD = 3.44 ft.
Area of triangle ABC = [tex]\frac{1}{2}[/tex] * base * height
=[tex]\frac{1}{2}[/tex] * 5 ft. 3.44 ft. = 8.59 square feet.
Area of pentagon = area of 5 similar triangle
= 5 * area of triangle ABC
= 5 * 8.59 = 42.96 square feet
Area of trapezoid = [tex]\frac{1}{2}[/tex] * (sum of the parallel side) * height
= [tex]\frac{1}{2}[/tex] * (5+8) * 4.5
= [tex]\frac{1}{2}[/tex] * 13 * 4.5 = 29.25 square feet.
Total square feet of wood required = area of pentagon + area of trapezoid
= 42.96 + 29.25 = 72.21 square feet
Rounding to one decimal place 72.21 square feet ≈ 72.2 square feet.
Thus, 72.2 square feet of wood will the company need to cover the deck designer shaped like a regular pentagon and a trapezoid.

I need to make my birthday into a polynomial my birthday is 11/01/2005
EXPLANATION:
To express a number or value as a polynomial we must take into account some steps:
-The polynomial may or may not have grouping signs.
-The polynomial can have more than one variable, constants and exponents.
-A polynomial must be ordered, the monomials that form it must be written from highest to lowest degree.
Since a polynomial is an algebraic expression that shows the sum of monomials and we have 3 separate monomials, so we must do the following:
[tex]\begin{gathered} (11)\rightarrow a\text{ monomial} \\ (01)\rightarrow a\text{ monomial} \\ (2005)\rightarrow a\text{ monomial} \\ \text{Now }we\text{ add }the\text{ t}hree\text{ }monomials\colon \\ (2005+11+01);\text{ there }the\text{ poly}nomial\text{ }must\text{ be organized }from \\ highest\text{ }to\text{ lowe}st\text{ }coefficient; \\ \text{ANSWER: (2005+11+01)} \end{gathered}[/tex]the number of girls is 75% of the number of boys.There are 28 students altogether. how many are girls and how many are boys?use a tape diagram

Boys + girls = 28

how do you do how do you point plot on a graph
To point plots on a graph, take the following steps:
1. Identify the x-coordinates and y-coordinates from the variable/data you have. It should be written in this form: (x, y)
2. Label both axes on the graph(x-axis and y-axis). The x-axis is usually on the horizontal line while the y axis is the horizontal line.
3. Start plotting your first 2 points on both axes (usually the numbers on first row). Plot the x value and also plot the y value at the appropriate points
4. Finally, Continue plotting the numbers by pointing each point on the graph (take them in rows)

his heart would beat 432 times in 3 minutes
Explanation
we can easily solve this by using a rule of three,
then
Step 1
to do that we need the same measure unit for the time, let's use seconds
so, we need to convert 3 minutes into seconds,
the equivalence is
[tex]1\text{ minute = 60 seconds}[/tex]hence, to convert from minutes into seconds just mutlply by 60
then
[tex]3\text{ minutes}\Rightarrow3\cdot60\text{ seconds=180 seconds}[/tex]Step 2
now, let's make the proportion
let x represents the number of times his heart would be in 180 seconds( 3 minutes)
so
[tex]\begin{gathered} \text{if} \\ 24\text{ beats}\Rightarrow10\text{ s} \\ \text{then} \\ x\text{ beats}\Rightarrow180\text{ s} \end{gathered}[/tex]so, the proportion is
[tex]\begin{gathered} \frac{24\text{ beats}}{10\text{ s}}=\frac{x}{180\text{ s}} \\ \frac{24}{10}=\frac{x}{180} \\ \end{gathered}[/tex]finally, to solve for x multiply both sides by of the equation by 180 and reduce
[tex]\begin{gathered} \frac{24}{10}=\frac{x}{180} \\ \frac{24}{10}\cdot180=\frac{x}{180}\cdot180 \\ \frac{4320}{10}=x \\ 432=x \end{gathered}[/tex]therefore, his heart would beat 432 times in 3 minutes

95 packages must be delivered daily to make a profit of $33.
What is the meaning of profit?
Profit is the term used to describe the financial gain experienced when the revenue from a commercial activity exceeds the costs, costs, and taxes associated with maintaining that activity.
Given that the delivers cost per packets is $2.60 and the cost to run a truck is $252.
Assume that they need deliver x packs of cookies to make a profit of $33.
The total cost to deliver x packs of cookies is $(2.60x + 252).
Given that company charges $5.60 per pack.
The revenue is $5.60x.
The total profit is $(5.60x - (2.60x + 252)) = $(5.60x - 2.60x - 252) = $(3x - 252).
Given that the profit is $33.
Thus 3x - 252 = 33
Add 252 on both sides:
3x = 285
Divide both sides by 3:
x = 95.
