180 in² - the area
width × lenght - the area
length : width = 5 : 4 therefore length = 5x and width = 4x
(x - some unit of length)
The equation:
(5x)(4x) = 180
20x² = 180 <em>divide both sides by 20</em>
x² = 9 → x = √9 → x = 3 in.
The length = 5x, therefore your answer is:
<h3>5x = 5(3 in) = 15in</h3>
Answer:
Step-by-step explanation:
Given
Reader' Book Club
per book
Perfect Page
per book
Required
Write an inequality to represent the situation
<em>Represent the number of books with b</em>
First, we need to write an expression for Reader's book
This is:
= Membership + Books Read
For Perfect Page
This is
= Books Read
For Reader's club to be less than Perfect Page, we have:
Answer:
It’s C
Step-by-step explanation:
<span>Hello! Lets solve this step by step! :)
Okay so we are ganna use the Pythagorean theorem.
</span><span>Since we know that FG = 10 cm, BC = 8 cm, and AB = 9 cm, we can now plug those numbers into our equation. So we take 8 squared + 9 squared = c squared
</span>So thats 81+64=c^2
<span>145=c^2
and √145 =</span><span><span>12.0415945788
Now we round it</span> to the nearest tenth of a centimeter and that gives us 12.04 So thats our answer! :)
Hope this helped if you have any other questions or would like further explanation just let me know!! :)
