-A triangle has sides with the measure of 11m, 11m, and 25m. State if this is a triangle
or not.
is it a triangle?
Answer:
Nope
Step-by-step explanation:
According to the Triangle Inequality Theorem, any 2 sides of the triangle must always be more than the third. Here, we can see that the theorem is violated because 11 + 11 < 25. Therefore, it is not a legitimate Triangle.
please tell me the step process of this btw this is 7th-grade math its angle measurements I'm confused about the process pls help.
Answer:
Angle BDA is 90°
(2x + 3) + 55 = 90
2x + 3 + 55 = 90
2x + 58 = 90
2x = 90 - 58
2x = 32
x = 32/2
x = 16
Hence,
x=16
x=16Angle BDA is 90°.

Write an equation for:
The sum of the square of a number and a second number is eighteen.
Answer:
x^2 + y = 18
Step-by-step explanation:
The equation is
Let us assume the first number be x
And, the second number be y
Since in the question it is mentioned that the sum of square of a number and the second number is eighteen
That means
x^2 + y = 18
This represent the equation

Answer:
23.64
Step-by-step explanation:
By Pythagoras Theorem:
[tex] {x}^{2} = {28}^{2} - (25 - 10)^{2} \\ \\ {x}^{2} = {28}^{2} -15^{2} \\ \\ {x}^{2} = 784 - 225 \\ \\ {x}^{2} = 559 \\ \\ x = \sqrt{559} \\ \\ x = 23.6431808 \\ \\ x = 23.64[/tex]

Last night, 4 friends split the dinner bill evenly. Each friend paid $12.75 and left the same amount for a tip. The bills total was $61. What equation could describe the situation?
Answer: 4 * (12.75 + x) = 61
Step-by-step explanation:
Each of the 4 friends paid $12.75 so that is:
= 4 * 12.75
Assuming the tip is denoted as x it would be:
= 4x
Putting them together is:
4 * (12.75 + x) = 61
Solving the equation would give:
4 * (12.75 + x) = 61
51 + 4x = 61
4x = 61 - 51
x = 10/4
x = $2.50
y = -1
4x + 3y = -19

What is the measure of angle X, to the
nearest degree?
Answer:
56 degrees
Step-by-step explanation:
Assuming this is trigonometry, you use the tangent method. Which means in order to find the angle you put the adjacent side of what your finding and the opposite on top of it.
The equation is tan(angle)= 9/6
You multiply both sides by the arch of tangent and get
angle =tan^-1 (9/6)
I inserted it into my geometry calculator and got 56.30993247, I rounded to the nearest degree and got 56 degrees
Answer:
56°
Step-by-step explanation:
Solve for x in the figure below
33
2x + 30
41
Given:
An exterior angle of a triangle = 2x+30°
Two opposite interior angles are 33° and 41°.
To find:
The value of x.
Solution:
According to the exterior angle thereom, the exterior angle of a triangle is equal to the sum of opposite interior angles.
Using exterior angle theroem, we get
[tex](2x+30)^\circ=33^\circ+41^\circ[/tex]
[tex](2x+30)^\circ=74^\circ[/tex]
[tex](2x+30)=74[/tex]
On further simplification, we get
[tex]2x=74-30[/tex]
[tex]2x=44[/tex]
[tex]x=\dfrac{44}{2}[/tex]
[tex]x=22[/tex]
Therefore, the value of x is 22.

In a drawer, a dentist keeps 11 mint, 4 grape, and 5 orange flavored toothpastes, What is the theoretical probability of randomly selecting a grape toothpaste?
Answer:
The probability of randomly selecting a grape toothpaste is 4:20.
Step-by-step explanation:
I hope this helps and I hope u have an Amazing Day!
Answer:
The theoretical probability of selecting a grape toothpaste is 4/20.
Step-by-step explanation:
There are 20 toothpastes in total, you want to find out about the grape. The chances of you picking grape is out of 20, so it's 4/20 since there's only 4 grape.

9514 1404 393
Answer:
y = 5x +50y = 10x10 monthsStep-by-step explanation:
The equation for the charge (y) by Bethany's company for x months is ...
y = 5x +50
The equation for the charge (y) by Kami's company for x months is ...
y = 10x
The charges are equal when ...
y = y
5x +50 = 10x . . . . use the expressions for y
50 = 5x . . . . . . . . subtract 5x
10 = x . . . . . . . . . . divide by 5
The companies will charge the same for 10 months.

A sum of money is to be divided among three girls, Anna, Barbara and Chrissy in the ratio 5 : 3 : 2. If Barbara received $400 less than Anna, calculate the amount of money each girl received.
Answer:
Anna received $1000
Barbara received $600
Chrissy received $400
Step-by-step explanation:
Let us solve the problem
∵ The ratio of Anna, Barbara, and Chrissy is 5: 3: 2
∵ Barbara received $400 less than Anna
→ That means Anna - Barbara is 400, find the difference between their ratio
∵ The difference between their ratio = 5 - 3 = 2
→ By using the ratio method
→ Anna : Barbara : difference
→ 5 : 3 : 2
→ A : B : 400
→ By using the cross multiplication
∵ A × 2 = 5 × 400
∴ 2A = 2000
→ Divide both sides by 2
∴ A = 1000
∴ Anna received $1000
∵ B × 2 = 3 × 400
∴ 2B = 1200
→ Divide both sides by 2
∴ B = 600
∴ Barbara received $600
Let us use the ratio between Anna and Chrissy to find the amount of Chrissy
→ Anna : Chrissy
→ 5 : 2
→ 1000 : C
→ By using cross multiplication
∵ 5 × C = 2 × 1000
∴ 5C = 2000
→ Divide both sides by 5
∴ C = 400
∴ Chrissy received $400
