O c. 14°
O d. 2,160°
Answer:
the sum of interior angles of a 14 sided shape be 2160
Answer: D) 2160
Work Shown:
S = sum of the interior angles of a polygon with n sides
S = 180(n-2)
S = 180(14-2)
S = 180*12
S = 2160

Multiply. Write your answer as a fraction in simplest form. −1/4×(−4/3)=
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given
- [tex]\frac{1}{4}[/tex] × - [tex]\frac{4}{3}[/tex] ( negative times negative = positive )
= [tex]\frac{1}{4}[/tex] × [tex]\frac{4}{3}[/tex] ( cancel the 4 on the numerator and denominator )

Find type of angle and solve for x.Please help.
Step-by-step explanation:
72° and a° is the angle of a straight line so
a+72°=180
a=180-72
a=108°
By using alternate exterior angle definition:
7x+24=180
7x=108-24
7x=84
x=84/7
x=12

A jar contains 30 red marbles, 50 green marbles, and 20 blue marbles. What is the probability of getting a
marble that is not red when drawing one at random?
Answer:
P(not red marble)=8/11
Step-by-step explanation:
sample space is 110
subtract the red (30)
110-30=80
80/110=8/11

If two lines intersect, they intersect at two different points.
is this statement true or false
Answer: False
If two lines intersect, then they intersect at one point only, so it makes no sense to mention a second point. This is assuming that we're not talking about two lines intersecting infinitely many times (i.e. one line overlapping another perfectly).

there are 78.1 grams of carbon in a sample of 92.7 grams of octane. what is the percent of carbon within the sample of octane?
The percent of carbon within the sample of octane is 84.25%
A percentage is a fraction of a total amount divided into hundred parts
The percent of carbon within the sample of octane = (grams of carbon / grams of octane) x 100
(78.1 g / 92.7 g) x 100 = 84.25%
To learn more about percentages, please check : https://brainly.com/question/19179977?referrer=searchResults
The percent of carbon within the sample of octane in the exercise is:
84.25%Calculation of percentages using the rule of three.
To make a calculation of the percentage of a sample, a simple rule of three can be used, where it is identified:
92.7 g → 100% 78.1 g → x
The octane sample is used as 100% since it is the total sample, while carbon is only a part of it, now we proceed to calculate:
[tex]x=\frac{78.1*100}{92.7}[/tex][tex]x=\frac{7810}{92.7}[/tex]x = 84.25026969x ≅ 84.25%In this way, it can be identified that the percentage of carbon in the octane sample is approximately 84.25%.

Answer:
A) $49
Step-by-step explanation:
There are two ways to solve this problem. You could either calculate the net change by adding up the values in the table and then adding that to the initial amount, or you could individually add every change in price to the initial amount. I'm going to go with the first way, as I find it to be quicker, but both methods work equally well.
We know that the stock was worth $52 on Monday morning. From the table, the net (or overall) change in the stock over the course of the week is:
-2 + 1 + 3 - 1 - 4 = -3
Therefore, the stock's price decreased by $3 over the week, and because the stock's original price was $52, we know it is now worth 52 - 3 = $49. Hope this helps!

Step-by-step explanation:
let the unknown number be x
now we are to find x regarding the question as an equation, let's form the equation to solve for x
the interpretation of the question is:
(x² + x)/3 = x
by collecting the like terms:
(x²+ x) = 3x
x² + x = 3x
x² = 3x - x
x² = 2x
x = 2

a. Find the value of sin2A, cos2A, tan2A and cot2A when sinA = 4/5 , cosA =4/5, tanA= 3/4 and cotA = 12/13
Step-by-step explanation:
Given,
SinA = 4/5
CosA =4/5
TanA= 3/4
CotA = 12/13
Sin²A = SinA²
Cos²A = CosA²
Tan²A = TanA²
Cot²A = CotA²
Therefore,
Sin²A = (4/5)²
Cos²A = (4/5)²
Tan²A = (3/4)²
Cot²A = (12/13)²
Sin²A = 16/25
Cos²A = 16/25
Tan²A = 9/16
Cot²A = 144/169
