The number that has a 4 in the hundred places.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
A 4 with a value ten times less than the 4 in the number 123,469.
First, the value of the 4 in the number 123,469 can be found by separating each digit as:
123,469 = 100,000 + 20,000 + 3,000 + 400 + 60 + 9
Then the value of the 4 is 400.
Now we want a number that has a 4 with a value then times less than 400. Then we have
400/10 = 40
Then we want a number that has a 4 in the hundred places.

Answer:
Part A
71°
Part B
The ladder is been used safely
Step-by-step explanation:
Part A
We solve the above question using Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = The distance between the house and the bottom of the ladder = 4 feet
Hypotenuse = Length of the ladder = 12 feet
x = Angle
Hence:
cos x = 4/12
cos x = 1/3
x = arc cos (1/3)
x = 70.528779366°
Approximately to the nearest degree
= 71°
Part B
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards. Is this ladder being used safely?
Angle x = 71°
Therefore, the ladder is been used safely
Width 2x-5 hope this helped
Equation:
16x = 20
**Solve the Equation**
16x/16 = 20/16
x = $1.25
