Answer:
First take 0.23 as 0.23/1
Then Multiply the numerator and denominator by any number, Let us say 100
So it becomes,
0.23 x 100/100
=> 23/100
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

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).

The quotient of 31 and the product of a number and - 8?
Answer:
[tex]\frac{31}{-8n}[/tex]
Step-by-step explanation:
Overall, the expression is a quotient, and you're dividing 31 by whatever the product is of -8 and an unknown number (a variable). The product of -8 and a number means you multiply them together
f(x) = -4x2 + 19
Find f(-7)
Step-by-step explanation:
Solution,
f(x) = -4x2 + 19
f(x)=-8+19
f(x)=27
As it is a constant function, therefore
f(-7)=27

What would the sum of the interior angles of a 14 sided shape be?
Select one:
O a. 360°
O b. 180°
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

Answer:
x=2
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
Answer:

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%.
