Answer:
Step-by-step explanation:
<h3>
The complete exercise is: "Twelve is no more than the sum of -1.5 times a number w and 4. Translate to number form"</h3>
You need to remember the meaning of the symbols of inequalities. These are:
means "Less than".
means "Greater than".
means "Less than or equal to".
means "Greater than or equal to".
By definition, the sum is the result of addition, then "The sum of -1.5 times a number w and 4" can be expressed as:
"Twelve is no more than..." indicates that the symbol of the inequality must be .
Therefore, you ca can write the following inequality:
Answer:
a = 9.849
b = 20.25
c = 491.03
Step-by-step explanation:
By using Pythagoras theorem in the right triangle BDC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
BC² = BD² + DC²
a² = 9² + 4²
a =
a =
a = 9.8489
a ≈ 9.849 units
By mean proportional theorem,
AD × DC = BD²
b × 4 = 9²
b =
b = 20.25 units
BY Pythagoras theorem in ΔADB,
AB² = AD² + BD²
c² = b² + 9²
c² = (20.25)² + 9²
c² = 410.0625 + 81
c = 491.0625
c = 491. 063 units
