Answer:
x = 9
Step-by-step explanation:
2x - 9 = x
2x - x = 9
x = 9
Answer:
The correct answer is 9.
Step-by-step explanation:
2x – 9= x <----- Here is the original problem.
2(9) – 9 = 9 <----- Replace the variables.
18 - 9 = 9 <----- Simplify the multiplication.
9 = 9 <----- This is a true statement.
Therefore, the correct answer is 9.

George is standing at the end of a 72 ft shadow cast by a tall building. The angle of elevation to the top of the tall building is . What is the height of the building?
Answer:
Errm please where is the angle of elevation
I think there should be an angle before we can find the height of the building
The height of the building is 44.91 feet
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
Given that George is standing at the end of a 72 ft shadow cast by a tall building. The angle of elevation to the top of the tall building is 34.
Therefore we have;
tan ° A = opposite / adjacent
° A = 31;
The adjacent (height) = 72 ft
Now replacing;
tan 34 ° = x / 72
x = tan 34 ° ( 72)
x = 44.91
Therefore, the height of the building is 44.91 feet

If V2=200mL, C1=80%, C2=50%, what is V1?
Answer:
125 mL
Step-by-step explanation:
We are given:
V₁ = x mL
C₁ = 80%
V₂ = 200 mL
C₂ = 50%
Solving for x:
We know that:
V₁C₁ = V₂C₂ [Concentration formula]
replacing the values:
x(80) = (200)(50)
x = 125 mL [Dividing both sides by 80]

Answer:
1. KLP + PLM = 180 degrees (straight line)
2. 3x + angle PLM = 180 degrees
3. angle PLM = 180 - 3x
4. PMN = P + PLM (Exterior angle)
5. 2x + 72 = x + 180 - 3x
6. x = 27
Step-by-step explanation:
1. Notice that angle KLP + angle PLM is a straight line, so KLP + PLM = 180 degrees (straight line)
2. angle KLP = 3x, so
3x + angle PLM = 180 degrees
3. angle PLM = 180 - 3x
4. PMN = P + PLM (Exterior angle)
5. 2x + 72 = x + 180 - 3x
6. 5 gives 4x = 108, so x = 27
Answer:
1. KLP + PLM = 180 degrees (straight line)
2. 3x + angle PLM = 180 degrees
3. angle PLM = 180 - 3x
4. PMN = P + PLM (Exterior angle)
5. 2x + 72 = x + 180 - 3x
6. x = 27
Step-by-step explanation:
ngl i didnt really get this i i kinda have a some what idea on what this is
The exterior angles of the triangle added to their corresponding interior angles equal 180 degrees by virtue of the sum of angles on a straight line.
As such the interior angles are
1. 180 - (x+ 3)
2. 180 - (2x+ 1)
3. 180 - (3x - 4)
Given that the sum of angles in a triangle is 180 degrees
180 - (x+ 3) + 180 - (2x+ 1) + 180 - (3x - 4) = 180
540 - 6x = 180
6x = 540 - 180
6x = 360
x = 60
The exterior angles are
x + 3 = 60 + 3 = 63
2x + 1 = 2(60) + 1 = 121
and
3x - 4 = 3(60) - 4 = 180 - 4 = 176
An Olympic-sized swimming pool holds 2,500,000 liters of water. How many gallons of water does an Olympic-sized swimming pool hold? Round your answer to the nearest tenth.
Answer:
The Olympic sized swimming pool hold 660501.9 gallons of water.
Step-by-step explanation:
Given that:
Water hold by an Olympic sized swimming pool = 2500000 liters
We know that;
1 gallon = 3.785 liters
Therefore,
We will divide the total number of water in liters by 3.785 to find the number of gallons.
Gallons of water in pool = [tex]\frac{2500000}{3.785}[/tex]
Gallons of water in pool = [tex]660501.9[/tex] gallons
Hence,
The Olympic sized swimming pool hold 660501.9 gallons of water.
