Answer:
72 degrees
Step-by-step explanation:
hi! the total angle measure of a triangle is 180 degrees. so, all three angle measures must add up to 180.
6x+6x+8x=180
20x=180
x=9
now, plug in x=9 for angle ABC.
8(9)= 72
m<ABC= 72 degrees

12. Factor completely: 64x^3 + 729
Answers
Answer:
(4 x + 9) (16 x^2 - 36 x + 81)
Step-by-step explanation:
Factor the following:
64 x^3 + 729
64 x^3 + 729 = (4 x)^3 + 9^3:
(4 x)^3 + 9^3
Factor the sum of two cubes. (4 x)^3 + 9^3 = (4 x + 9) ((4 x)^2 - (4 x) 9 + 9^2):
(4 x + 9) ((4 x)^2 - 4 9 x + 9^2)
4×9 = 36:
(4 x + 9) ((4 x)^2 - 36 x + 9^2)
Multiply each exponent in 4 x by 2:
(4 x + 9) (4^2 x^2 - 36 x + 9^2)
4^2 = 16:
(4 x + 9) (16 x^2 - 36 x + 9^2)
9^2 = 81:
Answer: (4 x + 9) (16 x^2 - 36 x + 81)
Answer:
(4x+9)(16x2−36x+81)
Step-by-step explanation:
Factor 64x3+729
64x3+729
=(4x+9)(16x2−36x+81)

if we have a geometric series with u1 = 2.1 and r= 1.06, what would the least value of n be such that Sn > 5543?
Answers
Answer:
88
Step-by-step explanation:
Write the expression for the sum in the relation you want.
Sn = u1(r^n -1)/(r -1) = 2.1(1.06^n -1)/(1.06 -1)
Sn = (2.1/0.06)(1.06^n -1) = 35(1.06^n -1)
The relation we want is ...
Sn > 5543
35(1.06^n -1) > 5543 . . . . substitute for Sn
1.06^n -1 > 5543/35 . . . . divide by 35
1.06^n > 5578/35 . . . . . . add 1
n·log(1.06) > log(5578/35) . . . take the log
n > 87.03 . . . . . . . . . . . . . . divide by the coefficient of n
The least value of n such that Sn > 5543 is 88.

A student did an experiment to test the hypothesis that brand name paper towels soak up water better than generic paper towels. What would be the independent variable in the student's experiment?
Answers
Answer: The independent variable is the brand and the dependant variable is the amount of water you use.
Step-by-step explanation:
The Independent variable is the condition that you change in an experiment.
The dependant variable is the condition that you measure in an experiment.
The independent variable in the student's experiment is the type of paper towel used.
In an experiment, there are three types of variables:
The independent variable : the experimenter can change or manipulate this variable in order to determine its effect on the dependent variable. The dependent variable : this is the variable whose value would be determined in the experiment.The extraneous variable : this is the variable that can affect the result of the experiment but it is not researched in the experiment.In this question the type of towel used would determine the amount of water that can be absorbed. This makes the type of towel used the independent variable. The dependent variable is the amount of water absorbed.

A square has an area of 200 square feet. Between what two consecutive integers would the
length of each side fall?
HELP ME PLEASE
Answers
Answer:
14 & 15
Step-by-step explanation:
The area of the square is given by the equation: [tex]A = s^2[/tex] so therefore the length of the side is: [tex]s = \sqrt{A}[/tex].
So we take [tex]s = \sqrt{200} = 14.14[/tex]
And this is between the integers 14 and 15.

Solve the following equation for a.
a-f=q
Answers
Answer:
a=q+f
Step-by-step explanation:
1. a-f=q
2. you need to do the opposite of -f which is +f to cancel it out
after that you need to do the +f to the q
Hope this helps
Using the literal equation a-f = q, the solution for a = p + q
What is literal equation?A literal equation are type of equations which have two or more unknown variables . A literal equation can be solved by adding or subtracting or multiplying or divide by same numbers to the both sides of the equation in order to solve the expression for the required variable.
For example if an given equation is x+ y =2 and we want to solve it for y
Then we will try to keep y on one side and take remaining terms to other side.⇒ y = x-2 is solution for y.
Given equation :
a- f = q
To solve for a, add f to both sides
⇒ a- f + f = q+ f
⇒ a = q + f
Solution for a is q +f.
