The ratio of the measures of the three angles in a triangle are 3:4:6. Determine the measures of each angle of the triangle.
Answers
Given:
The ratio of the angles is 3:4:6.
Required:
We need to find the measure of each angle of the triangle.
Explanation:
Let the angles of the triangle be 3x, 4x and 6x.
We know that the sum of the angles is equal to 180 degrees.
[tex]3x+4x+6x=180\degree[/tex][tex]13x=180\degree[/tex]Divide both sides by 13.
[tex]\frac{13x}{13}=\frac{180\degree}{13}[/tex][tex]x=13.85[/tex]Substitute x values in 3x, 4x and 6x.
[tex]3x=3\times13.85=41.55[/tex][tex]4x=4\times13.85=55.4[/tex][tex]41.55+55.4+6x=180[/tex][tex]6x=83.05[/tex]Final answer:
The angles are 41.55, 55.40 and 83.05.

Fibonacci, Pythagoras and Descartes went out for breakfast. The total bill was $38.50. The tax rate was 7% and they left a 20% tip. Determine the total bill. Round to the nearest hundredth.so how much will each person pay if the bill was equally divided?
Answers
Given:
• Total bill = $38.50
,• Tax rate = 7% = 0.07
,• Tip = 20% = 0.20
Let's find the total bill after tax and tip.
Now, to find the total bill we have:
Total bill = bill + tax amount + tip amount
Where:
[tex]\begin{gathered} \text{ tax amount = 0.07}\times38.50=2.695 \\ \\ Tip\text{ amount = 0.20 }\times38.50=7.7 \end{gathered}[/tex]The tax amount is $2.695
The tip amount is $7.70
Now, to find the total bill, we have:
Total bill = $38.50 + $2.695 + $7.7 = $48.895 ≈ $48.90
Therefore, the total bill rounded to the nearest hundredth is $48.90
Part B.
To find the amount each person will pay if the bill was equally divided, let's divide the total bill by the number of people.
Where:
Number of people = 3
Hence, we have:
[tex]\frac{48.90}{3}=\text{ 16.30}[/tex]Therefore, the amount each person will pay is $16.30
ANSWER:
(a). $48.90
(b). $16.30
solve for C -3 (C + 5)- (c-3)=32
Answers
Given the equation:
[tex]-3(c+5)-(c-3)=32[/tex]To find the value of 'c', the first step to do is to get rid of the parenthesis. We can do this using the distributive property on both cases:
[tex]\begin{gathered} -3(c+5)-(c-3)=32 \\ \Rightarrow-3\cdot c+(-3)\cdot5-c-(-3)=32 \\ \Rightarrow-3c-15-c+3=32 \end{gathered}[/tex]Now that we don't have any parenthesis in our equation, we start moving similar terms: we leave on the left the terms with the variable 'c' and we move the rest of the terms to the right side with it's sign changed:
[tex]\begin{gathered} -3c-15-c+3=32 \\ \Rightarrow-3c-c=32+15-3 \end{gathered}[/tex]We can make the operations on each side since now we have the similar terms apart:
[tex]\begin{gathered} -3c-c=32+15-3 \\ \Rightarrow-4c=47-3=44 \\ -4c=44 \end{gathered}[/tex]Finally, we move the -4 that is multiplying the 'c' to the other side doing its opposite operation:
[tex]\begin{gathered} -4c=44 \\ \Rightarrow c=\frac{44}{-4}=-11 \\ c=-11 \end{gathered}[/tex]therefore, c=-11

Thend the card is returned to the deck and New card is cosen. the table below shows the results of choosing 14 cards. for which color of card is the experimental probability the same as the theoretical probabicaras.Results red= 10 black=2 blue=1green=1
Answers
From the question, we can find that we have 7 red cards
so, the probability of chosen at random a card is
p(red)= 7/28
p(black)= 12/28
p(blue) = 7/28
p(green)=2/28
As after picking a card we return the card to the deck, and given that we chose 14 cards, our theoretical number of chosen cards should be around
p(red) = (7/28)x14 = 3.5
p(black) = (12/28)x14 = 6
p(blue) = (7/28)x14 = 3.5
p(green)= (2/28)x14=1
so the color that the experimental probability is the same as the theoretical probability is green

An exponential decay function can be generically written as:
[tex]y=a\cdot b^x[/tex]The conditions for this function are:
1) The y-intercept is 4.
2) The values of y decrease by a factor of one half as x increases by 1.
The y-intercept corresponds to the value of y when x = 0, so we can express it as:
[tex]\begin{gathered} y=a\cdot b^x \\ 4=a\cdot b^0 \\ 4=a\cdot1 \\ a=4 \end{gathered}[/tex]This condition let us find the value of a.
The next condition will be used to find the value of b.
As x increases by 1, y decreases by one half.
We can write this as a quotient between consecutive values of y:
[tex]\begin{gathered} \frac{y(x+1)}{y(x)}=\frac{1}{2} \\ \frac{4\cdot b^{x+1}}{4\cdot b^x}=\frac{1}{2} \\ b^{x+1-x}=\frac{1}{2} \\ b^1=\frac{1}{2} \\ b=\frac{1}{2} \end{gathered}[/tex]Then, we can write the function as:

use the functions f (×) and g (×) to complete the comparison statements using <,>,or =.F(x)= -×-5
Answers
First Question:
f(3) = (-3)-5 (Replacing x in the equation)
f(3) = -8 (Operating integers)
From the table we see that g(3) = 8, therefore, f(3)< g(3)
Second Question:
The slope of f is the coefficient of x in the equation, so, the slope of f is -1.
Using the slope formula for g(x) with points (0,2) and (3,8) we find that:
[tex]m=\frac{y2-y1}{x2-x1}=\frac{8-2}{3-0}=\frac{6}{3}=2[/tex]The slope of g is 2.
Therefore, the slope of f is less (<) than the slope of g
Third Question:
The y-intercept of f is the value next to the term -x, so, it is equal to -5
The y-intercept of g can be found with the point (0,2), when x=0, y is equal to 2, then the y-intercept is 2.
Therefore, the y-intercept of f is less(<) than the y-intercept of g.

Answers
Answer
Option B is correct.
64x³ + 27 = (4x + 3) (16x² - 12x + 9)
Explanation
We are told to factorize
64x³ + 27
To do this, we use the factorization of (x³ + y³) as a guide. First of,
(x + y)³ = (x + y) (x + y)² = (x + y) (x² + 2xy + y²)
(x + y)³ = x³ + y³ + 3x²y + 3xy²
So, we can write
x³ + y³ = (x + y)³ - 3x²y - 3xy² = (x + y)³ - 3xy(x + y)
= (x + y) [(x + y)² - 3xy]
= (x + y) (x² + y² + 2xy - 3xy)
= (x + y) (x² - xy + y²)
So, comparing (64x³ + 27) with (x³ + y³), we can see that
64x³ = (4x)³
27 = (3)³
(64x³ + 27) = (4x)³ + 3³
x³ + y³ = (x + y) (x² - xy + y²)
(4x)³ + 3³ = (4x + 3) [(4x)² - (4x × 3) + 3²]
= (4x + 3) (16x² - 12x + 9)
Hope this Helps!!!

indicate whether (2, 7) is a solution of the given system.y is greater than or = -x+1Y is less than 4x+2
Answers
In order to determine if the point (2, 7) is a solution to the given system of inequalities we just have to replace 7 for y and 2 for x and see if the two inequalities are met, like this:
For y ≥ -x + 17 ≥ -2 + 1
7 ≥ -1
As you can see, 7 is greater than -1 then the first inequality is met.
For y < 4x + 27 < 4(2) + 2
7 < 8 + 2
7 < 10
As you can see, the second inequality is also met, then (2, 7) is a solution for the system of inequalities.

In other words, the circumference would be the length of the circle's arc if it were opened out and straightened out to a line segment. Any great circle's circumference, or the distance between any two planes that cross a sphere's center, is measured in meters. Any large circle that traverses a pole-designated point is known as a meridian. The shortest path between any two locations on a sphere is referred to as a geodesic.
