Answer:
1980°
Step-by-step explanation:
The formula for the sum of interior angles of an n-gon is ...
angle sum = 180°(n -2)
For n=13, the angle sum is ...
angle sum = 180°(13 -2) = 180°×11
angle sum = 1980°

It due 30 mins
Answer:
95°
Step-by-step explanation:
Well first draw a parallel to p, let's say r
so we have that
[tex]\angle 2+\angle3=\angle1[/tex]
and
[tex]\angle y=148\\\\\angle x +63=180\\\\\angle x=117[/tex]
so now by internal angles of parallels we know that
[tex]\angle x +\angle 2 = 180\\\\\angle y +\angle 3 = 180[/tex]
which is
[tex]117+\angle 2 = 180\\\\\longrightarrow \angle 2 = 63\\\\148+\angle 3 = 180\\\\\longrightarrow \angle3=32[/tex]
so
[tex]\angle 1 = 63+32\\\\\angle 1 = 95[/tex]

Plsssss help??? Also do any of u know a graphing app that shows u the points and were to put them?
Answer:
See below
Step-by-step explanation:
There are two ways to graph an equation.
1st Way:
We can use a graphing calculator. (See the attached file)
2nd Way:
We can take the values of x as 0, 1 , 2 (Or anything).
Then, We have to put the values of x in the equation to get the value of y accordingly.
According to these values, Plot the graph.
Also,
Slope = 5 / 6
y-intercept = 1

What is a simplified eCarlotta thinks that 3y + 5y3 is the same as 8y4. Which statement shows that it is NOT the same?Xpression for (x + y) – (x – y)?
Questions:
(a) What is a simplified expression for (x + y) – (x – y)?
(b) Carlotta thinks that [tex]3y + 5y^3[/tex] is the same as [tex]8y^4[/tex]. Which statement shows that it is NOT the same?
Answer:
[tex](x + y) - (x - y) =2y[/tex]
[tex]3y + 5y^3 \ne 8y^4[/tex]
Step-by-step explanation:
Solving (a):
Given
[tex](x + y) - (x - y)[/tex]
Required
Simplify
[tex](x + y) - (x - y)[/tex]
Open brackets
[tex](x + y) - (x - y) = x + y - x + y[/tex]
Collect Like Terms
[tex](x + y) - (x - y) = x - x+ y + y[/tex]
[tex](x + y) - (x - y) = y + y[/tex]
[tex](x + y) - (x - y) =2y[/tex]
Solving (b):
Given
[tex]3y + 5y^3[/tex] and [tex]8y^4[/tex]
Required
Which expression shows they are not the same
The expression that shows this is:
[tex]3y + 5y^3 \ne 8y^4[/tex]
Take for instance; y=2
Substitute 2 for y in [tex]3y + 5y^3 \ne 8y^4[/tex]
[tex]3*2 + 5*2^3 \ne 8*2^4[/tex]
Evaluate all exponents
[tex]9 + 5*8 \ne 8*16[/tex]
[tex]9 + 40 \ne 128[/tex]
[tex]49 \ne 128[/tex]
The above expression supports [tex]3y + 5y^3 \ne 8y^4[/tex]

Taylor purchased 9 pints of ice cream for a party. If each guest will be served exactly 1 2 2 1 pint of ice cream, how many guests can Taylor serve?
Complete question :
Carly purchased 9 1/2 pints of ice cream for a party. If each guest will be served exactly 3/5 pint of ice cream, what is the greatest number of gusts that Carly can serve
Answer:
15 guests
Step-by-step explanation:
Given that:
Total pints of icecream = 9 1/2
Fraction of ice cream pints per guest = 3/5 pints
Number of guest that can be served :
Total pints / fraction per guest
9 1/2 ÷ 3/5
19/2 * 5/3
95 / 6
= 15.8 guest
Hence, greatest Number of guest that can be served = 15
