Answer:
No
Step-by-step explanation:
You use the formula a^2 + b^2= c^2. The biggest number is c.
So 8 ^2 + 10^2 has to equal 12^ 2
64 + 100= 144
164=144
That is not true.
Answer:
No, they are not
Step-by-step explanation:
If you simplify all 3 numbers, you get 4, 5, 6
If you graph the triangle on graph paper, it wouldn't work and there would be a gap.

Which is greater,-2 4/9 or -2.25
Answer: -2.25
Step-by-step explanation:
-2 4/9 or -2.25
Convert this to decimal
-2 4/9
4/9=0.4444
Add to the 2
-2.4444
-2.444 or -2.25
In negative rule,the lower the value,the greater the number
Therefore,
-2.25 is greater than -2.444

There are 100 applicants applying for three equal cosmetology positions. How many different groups of
three can be selected to fill the positions?
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The number of different groups of three people that can be selected to fill the positions is 970,200.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that there are 100 applicants applying for three equal cosmetology positions.
Now, if a person takes up a position the same person can not take the other position, therefore, only 99 people will be left for the second position.
The same will happen with the third position, therefore, there will be only 98 people that can take the third position.
Therefore, the number of different groups of three people that can be selected to fill the positions is,
Number of different groups
= Number of applications to feel the first position × Number of applications to feel the second position × Number of applications to feel the third position
= 100 × 99 × 98
= 970,200
Hence, the number of different groups of three people that can be selected to fill the positions is 970,200.

The height of a right circular cone is multiplied by 4, but its radius remains fixed. By what factor will the volume of the cone be multiplied?
A. 1/4
B. 4
C. 8
D. 16
Answer:
B
Step-by-step explanation:
Because the height is only used once (not squared) in the cone volume formula, the volume is only multiplied by 4.
The volume of the right circular cone must be multiplied by 4.
The correct answer is option (B). 4
What is the volume of the right circular cone?[tex]V=\frac{1}{3}\times \pi \times r^{2} \times h[/tex], where 'r' is the radius of circular base and 'h' is the height of the right circular cone.
For given example,
The height of the right circular cone is multiplied by 4, but its radius remains fixed.
From the formula of the volume of the right circular cone,
[tex]V\propto h[/tex]
This means, as height of the cone increases, the volume of the cone increases at the same rate.
As the height of a right circular cone is multiplied by 4, the volume of the cone must be multiplied by factor 4.
Therefore, the correct answer is option (B). 4

I don’t know how to find the value.
Answer:
x=20
Step-by-step explanation:
The angles are vertical angles, which means they are equal
2x+20 = 60
Subtract 20 from each side
2x+20-20 = 60-20
2x = 40
Divide each side by 2
2x/2 = 40/2
x =20
Answer:
x=20. C.
Step-by-step explanation:
You see, 2x plus 20 and 60 are vertical angles. They are angles that go head to head. Vertical angles are also congruent, so if they are congruent you can write an equation, 2x+20=60. Solve for x, minus both sides by 20, and you get 2x=40. Divide both sides by 2 and you get x=20. Hope this helps!

The left denominator is : 8
The right denominator is : 4

Factor Left

Denominator L.C.M = Max
{Left,Right}

Calculating Multipliers :
3.2 Calculate multipliers for the two fractions
Denote the Least Common Multiple by L.C.M
Denote the Left Multiplier by Left_M
Denote the Right Multiplier by Right_M
Denote the Left Deniminator by L_Deno
Denote the Right Multiplier by R_Deno
Left_M = L.C.M / L_Deno = 1
Right_M = L.C.M / R_Deno = 2
Making Equivalent Fractions :
3.3 Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. 5x
—————————————————— = ——
L.C.M 8
R. Mult. • R. Num. 2
—————————————————— = —

Adding fractions that have a common denominator :
3.4 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

Equation at the end of step 3 :

Step 4 :
When a fraction equals zero :
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
5x-2
———— • 8 = 0 • 8
8
Now, on the left hand side, the 8 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
5x-2 = 0
Solving a Single Variable Equation :
4.2 Solve : 5x-2 = 0
Add 2 to both sides of the equation :
5x = 2
Divide both sides of the equation by 5:
x = 2/5 = 0.400
One solution was found :
x = 2/5 = 0.400
