What is the mode of the data set shown below?
{10, 2, 8, 9, 5, 2, 6}
A. 42
B. 7
C. 6
D. 2
Answer:
d. 2
Step-by-step explanation:
a mode is the most frequently appeared value in a set of data. in other words, the most repeated number in a set of x, y, z.
example:
2, 3, 8, 7, 8, 7, 8
number of times 2 appeared: 1
number of times 3 appeared: 1
number of times 7 appeared: 2
number of times 8 appeared: 3
the mode here would be 8, since it is the most repeated number.

Name the theorem or postulate that can be used to prove that these triangles are similar
Answer:
SSS similarity.
Step-by-step explanation:
AA, SAS, and SSA similarities means the triangle must have an angle, which it doesn't, so by process of elimination it is SSS similarity.
By AA similarity criteria, the triangle AOB is similar to the triangle COD. Therefore, option A is the correct answer.
In the given figure, two lines AB and CD are parallel.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Consider, the triangle AOB and the triangle COD.
Here, AB║CD
∠BAO=∠CDO (Alternate interior angles)
∠ABO=∠DCO (Alternate interior angles)
By AA similarity criteria ΔAOB≈ΔCOD
By AA similarity criteria, the triangle AOB is similar to the triangle COD. Therefore, option A is the correct answer.

Answer:
x = 14.375
Step-by-step explanation:
Ok, so we know that a triangle has a total interior degree of 180°. And since we already have a 95° angle, we just need to subtract 95 from 180.
180° - 95° = 85°
Now, we already have indicators that two of the three sides are equal. And we already got the angle of the side that does not have a matching partner. So we just need to divide what we already have by 2.
85° / 2 = 42.5°
Now that we know each side is 42.5 degrees, we just need to grab our given equation and put and equal sign at the end with what we already know is the answer (since we are trying to solve for x).
(4x - 15) = 42.5
Now, let's just get rid of those useless parentheses.
4x - 15 = 42.5
Next, we just need to have the variable on its own side, all by itself. So, in order to do that, we just add 15 to both sides.
4x = 57.5
Now, for our final step, we just need to divide each side by our variables' factor (which is a positive 4). In which we get our final answer of:
x = 14.375
Answer:
x = 14.375
Step-by-step explanation:
Since 2 sides are congruent then the triangle is isosceles and the base angles are congruent, both (4x - 15)
The sum of the 3 angles in the triangle = 180°
sum the angles and equate to 180
4x - 15 + 4x - 15 + 95 = 180 , that is
8x + 65 = 180 ( subtract 65 from both sides )
8x = 115 ( divide both sides by 8 )
x = 14.375

What is the first step needed to solve 4 over 7 the whole multiplied by x minus 5 equal negative 13?
Subtract 13 from both sides
Divide both sides by 7
Add 5 to both sides
Multiply both sides by 4
Answer: Add 5 to both sides
What is the first step needed to solve 4 over 7 the whole multiplied by x minus 5 equal negative 13?
Answer- Add 5 to both sides
(4/7)x - 5 = -13
• As mentioned above, first step would be,
adding 5 to both sides
=> (4/7)x - 5 + 5 = -13 + 5
=> (4/7)x = -8
• Now, transporting 7 from L.H.S. to R.H.S
=> 4x = -8 × 7
=> 4x = -56
• Now in the same way, transporting 4 from L.H.S. to R.H.S
=> x = (-56/4)
=> x = -14
• And in this way, or taking (Add 5 to both sides) as our first step, we find that the value of x is -14.
∴ x = -14

Answer:
C
Step-by-step explanation:
To simplify this equation,
-x+10<2
-10 from both sides
-x<-8
Take out the negative
x<8
This means x is less than 8
For ≤ and ≥ , use a closed dot to indicate the number itself is part of the solution.
For < and >, use an open circle to indicate the number itself is not part of the solution.
In this case you use a open circle and becasue x is less than 8, the arrow pointing left is correct.

Which expression(s) is (are) equivalent to
5(x + 9) + 7(y + 2) - x?
Select ALL that apply.
A. 5x + 9 + 7y + 2 - x
B. 4x + 7y + 59
OC. 5x + 45 + 7y + 14 - X
D. 11xy + 11
OE. 4x + 7y + 11
OF. 11xy + 59
Answer:
OC. 5x + 45 + 7y + 14 - X, OE. 4x + 7y + 11
Step-by-step explanation:
Because, 5(x + 9) is 5x + 45 and 7(y + 2) is 7y + 14 and so you simplify by simplifying the like terms for example 5x - x = 4x 45 + 14 = 59 and 7y stays the same.
The expression 5(x + 9) + 7(y + 2) - x can be equivalent to 4x + 7y + 59 and 5x + 45 + 7y + 14 - x, so option B and C are correct.
What is expression?A mathematical expression is made up of a statement, at least two integers or variables, and one or more arithmetic operations.
Given expression:
5(x + 9) + 7(y + 2) - x
If you simplify, you will get,
5x + 45 + 7y + 14 - x,
And as further simplified we get,
4x + 7y + 59
Therefore, the expression 5(x + 9) + 7(y + 2) - x can be equivalent to 4x + 7y + 59 and 5x + 45 + 7y + 14 - x.

Two angles of a triangle measures 55° and 25° what is the measure of the third angle of the triangle
Answer:
100°
Step-by-step explanation:

Two brothers, Jim and John, had a straight log in their backyard. Jim wanted the log cut into 24 equal parts. He painted red lines on the log and called to a lumberjack to cut the log by the painted lines. John wanted the log cut too, but into 18 equal parts. He painted yellow lines on the log with some yellow lines painted over red lines. The lumberjack came and cut the log by the painted lines. How many cuts did the lumberjack make?
Answer:
432
Explanation:
If the lumberjack follows Jim's instruction and cuts the log of wood into 24 parts the first time, the log of wood has 24 parts
If the lumberjack follows John's instruction to further cut the log of wood already cut into 24 parts then we would have 24×18= 432 parts of the log of wood

What is the equation of the line in slope-intercept form?
Answer:
y = ⅗x
Step-by-step explanation:
The line passes through the point of origin, (0, 0). This implies that the graph represents a proportional relationship between x and y. Thus, in slope-intercept form, the line of a proportional graph can be represented as y = mx.
Where,
m = slope/constant of proportionality = y/x
To write an equation for the line, let's find the slope using any of the points on the line.
Using (50, 30):
Slope (m) = 30/50 = ⅗
Plug in the value of m into y = mx
Thus, equation of the line would be:
y = ⅗x

Step-by-step explanation:
Given the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AE}{AC}[/tex] = [tex]\frac{DE}{BC}[/tex], substitute values
[tex]\frac{x}{4}[/tex] = [tex]\frac{12.5}{5}[/tex] ( cross- multiply )
5x = 50 ( divide both sides by 5 )
x = 10
and
[tex]\frac{AD}{AB}[/tex] = [tex]\frac{DE}{BC}[/tex] , that is

does his ladder need to be in feet?
8.7 ft
o 3.6 ft
39.6 ft
O 12.2 ft
Answer:
The ladder has 39.6 feet
Step-by-step explanation:
Length Units Conversion
To convert from meters to feet we use the relation
1 m = 3.3 ft
The ladder that Nicholas needs to repair the roof of his grandmother's hours is 12 meter long.
Converting this length to feet we have
12 * 3.3 = 39.6 ft
The ladder has 39.6 feet
