ABC is equilateral, each angle has a measure of 9x-12
Answers
Answer:
x=8
Step-by-step explanation:
Angles in a Triangle always add up to 180
So, 3(9x-12)=180
27x-36=180
216=27x
x=8
The angle of the equilateral triangle is 60° and x is 8.
What is a Triangle?A triangle is a polygon with three sides and three vertices.
The triangle's total number of angles comes to 180°.
Given, measure of angle of an equilateral triangle 9x-12.
The sum of all the angles of the triangle is 180°.
That means,
3(9x-12) = 180°
27x = 180+36
x = 216 / 27
x =8
Therefore, the value of x is 8.

Find the GCF of 60, 96, and 156.
Answers
Answer:
GCF = 12
for the values 60, 96, 156
Step-by-step explanation:
Solution by Factorization:
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
The factors of 156 are: 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
Then the greatest common factor is 12.
A) Convert the exponential function, 12^3=x^4 y^3 z^6, to its corresponding logarithmic function.
B) Write the log form from Part A into the expanded log form. **expression must be fully expanded for full credit**
Answers
The logarithmic function is ㏒ 12³ = ㏒ x⁴ · y³ · z⁶. The equation into the expanded logarithmic form is 3 · ㏒ 12 = 4 · ㏒ x + 3 · ㏒ y + 6 · ㏒ z.
How to apply logarithms on a exponential function
Logarithms are the reciprocal of exponential functions. In this question we must apply logarithms and its properties to obtain a linear-like expression in the following lines. The logarithm properties are summarized below:
㏒ₐ (b/c) = ㏒ₐ b - ㏒ₐ c (1)
㏒ₐ (b · c) = ㏒ₐ b + ㏒ₐ c (2)
㏒ₐ bⁿ = n · ㏒ₐ b (3)
a) To obtain the corresponding logarithmic function we apply logarithms on both sides of the expression:
㏒ 12³ = ㏒ x⁴ · y³ · z⁶ (4)
The logarithmic function is ㏒ 12³ = ㏒ x⁴ · y³ · z⁶. [tex]\blacksquare[/tex]
b) The expanded logaritmic form of (4) consists in the addition and subtraction of logarithms of non-power numbers, whose formed could be found, if possible, by logarithm properties:
㏒ 12³ = ㏒ x⁴ · y³ · z⁶
㏒ 12³ = ㏒ x⁴ + ㏒ y³ + ㏒ z⁶
3 · ㏒ 12 = 4 · ㏒ x + 3 · ㏒ y + 6 · ㏒ z
The equation into the expanded logarithmic form is 3 · ㏒ 12 = 4 · ㏒ x + 3 · ㏒ y + 6 · ㏒ z. [tex]\blacksquare[/tex]

Step-by-step explanation:

When x = 4, y = -4 - 2 = -6.
To draw the graph plot the 3 points and you should be able to draw a straight line through them.
Answer:
The first y value with -3, is 1.
The second y value with 0, is -2.
The third y value with 4, is -6.
A graph is shown below.
Step-by-step explanation:
It states that the rule is y = -x-2. So all we do is plug in the values shown in the table.
y = -(-3)-2
y = 1
The first point of intersection is at (-3,1)
y = -(0)-2
y = -2
The second point of intersection is at (0,-2)
y = -(4)-2
y = -6
The third point of intersection is at (4,-6)
So now, we plot the points, and draw a line connecting them all.

Transformation involves changing the position of a shape through translation, dilation, rotation and reflection.Marcus's claim is correct.
What is transformation?A process by which one figure, expression, or function is converted into another one of similar value.
The triangles are given as: ΔTSR and ΔUSV
By comparison, we can see that point S is on both triangles, and this point on both triangles corresponds.
So, to map ΔTSR to ΔUSV, then ΔTSR must be rotated about point S to ΔUSV or rotate ΔUSV about point S to ΔTSR.
Hence, Marcus is correct, and Sam is not.

one over Two hundred and fifty
Step-by-step explanation:
As we can see the 4 is 2 zeros away from the decimal point. This means that 4 must be in the thousandths place.
Therefore our answer is four thousandths.
Remember that we it is behind the decimal point, it becomes ths at the end.
To change this into a fraction we should get 4/1000 by taking the words literally.
Dividing both sides by 4 gives us 1/250

32/21 miles in 1 3/5 hours
5/3 mikes in 1 9/10 hours
Answers
We want to find the mile per hour rate (mi/hr).
That is 2/3 divided by 7/10
Which is 2/3 times 10/7
Numerator is 20
Denominator is 21
So 20/21 miles per hour. .95238009…
Convert each answer (flipping the second fraction since it is division)
5/7 times 4/3 is 20/21
7/10 times 3/2 is 21/20
10/3 divided by 1.5 hours which is 3/2.
So 10/3 times 2/3 is 20/9
32/21 divided by 1 3/5 hours which is 5/5 plus 3/5 (add to get 8/5)
So 32/21 times 5/8 is 160/168
5/3 times 10/9 is 50/27
In order of answers
20/21
21/20
20/9
160/168
50/27
Original was 20/21 which is less than 1 (21/21)
So yes to 20/21
So no to 21/20, 20/9, 50/27
To see if 160/168 works simplify.
160/168 gives 80/84 gives 40/42 gives 20/21 when dividing by 2.
So 160/168 works.
So yes to
5/7 mile in 3/4 of an hour
32/21 miles in 1 3/5 hours
So no to
7/10 mile in 2/3 of an hour
10/3 miles in 1 1/2 hours
5/3 miles in 1 9/10 hours

Answers
So, s = 16.
One side is 15.
Let the second side be x.
So, the third side = 32 - 15 - x = 17 - x.
Area = 24 cm^2
So, 24^2 = s(s - 15)(s - x)(s - 17 + x)
So, 576 = 16(16 - 15)(16 - x)(16 - 17 + x)
So, 576 = 16*1(16 - x)( - 1 + x)
So, 576/16 = (16 - x)( - 1 + x)
So, 36 = - 16 + 17x - x^2
So, x^2 - 17x + 52 = 0
So, (x - 13)(x - 4) = 0
So, x = 13 or x = 4
So, the lengths of the remaining two sides are 4 cm and 13 cm.
