The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x. step by step explanation.
1 answer:
Answer:
The area of the rectangle in terms of 'x' = 13x
Step-by-step explanation:
- Perimeter = 30 cm
- Length = x cm
Using the perimeter formula to find the width w.
Dividing both sides by 2
as P = 30 cm
cm
Using the formula of the rectangle area
substitute w = 13 and l = x in the formula
Therefore, the area of the rectangle in terms of 'x' = 13x

Step-by-step explanation:
Given : Human body temperatures are normally distributed with a mean of and a standard deviation of
A hospital uses as the lowest temperature considered to be a fever.
Let x be the random variable that represents the human body temperatures.
For x= 100.6,
Using normal distribution table for z-values for right-tailed area ,
P(x>100.6)=
Hence, the required probability = 0.00102%
The acceleration of the bookshelf is equal to 1.30
<u>Given the following data:</u>
- Mass of bookshelf = 51.5 kilogram
- Net force = 67 Newton
To determine the acceleration of the bookshelf, we would apply Newton's Second Law of Motion:
Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on the object while being inversely proportional to its mass.
Mathematically, Newton's Second Law of Motion is given by this formula;
Substituting the given parameters into the formula, we have;
Acceleration = 1.30
