Answer:
l x - 9 l ≤ 0.3y
Step-by-step explanation:
Let x is the length of the pipe
Let y is the length of the diameter
Given that:
- A pipe is to be cut to a length of 9 accurate, we have : x - 9
- Within three tenths of its diameter : 0.3 y
So we have the inequality that model this situation is:
l x - 9 l ≤ 0.3y
Hope it will find you well.
Answer:
The population be after 15 years is 171376.
Step-by-step explanation:
Given : A population of 110,000 grows 3% per years 15 years.
To find : How much will the population be after 15 years?
Solution :
Exponential growth population model is given by,
Where,
P(t) is the population at time (t)
is the initial value of the population
r=3%=0.03 is the annual rate of growth
t=15 is the time in years.
Substitute the value,
Therefore, the population be after 15 years is 171376.

Solution:
Let us consider a rectangle as shown in the attached image in the answer area.
We are given the two adjacent sides of a rectangle and we have to find diagonal of the rectangle.
To find the diagonal, we can use the Pythagorean Theorem.
We are given the base and perpendicular of the right angled triangle and we have to find the hypotenuse.
According to Pythagorean theorem:

- Definition of a Line: A line is 180°
Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
(10y + 6)° + (8y - 6)° = 180°
<u>Step 2: Solve for </u><em><u>y</u></em>
- Combine like terms: 18y = 180
- Divide 18 on both sides: y = 10
