Multiply the amount of pages by the amount of words per page:
There are about 287000 words remaining.
Courtney can read at a rate of 110 words per minute. Since we want to find the amount of hours she needs to finish the book, multiply this rate by 60 to convert into an hour:
Courtney reads at a rate of 6600 words per hour.
Divide the amount of words in the book by Courtney's reading speed in hours:
Courtney will need to set aside 43.48 hours to complete her assignment.
Answer:
The amount of money that Darcy and Jason have together is $124
Step-by-step explanation:
Let
x -----> amount of money that Darcy has
y -----> amount of money that Jason has
z ----> amount of money that Maria has
we know that
------> equation A
----->
-----> equation B
-----> equation C
substitute equation B and equation C in equation A and solve for y
Find the value of x
----->
so
The amount of money that Darcy has is $52
The amount of money that Jason has is $72
therefore
$52+$72=$124
The amount of money that Darcy and Jason have together is $124

According to the statement of the question, we have:
a/b = 3/4
<em>Note that according to the attached figure, </em><em>b > a</em><em>, then the correct proportion will be </em><em>a</em><em> to </em><em>3</em><em>, as well as </em><em>b</em><em> to </em><em>4</em><em>, because </em><em>b > a</em><em> and </em><em>4 > 3</em>
Isolating a and b:
a = 3b/4
b = 4a/3
From Pythagoras:
h² = a² + b² - as a = 3b/4 and b = 4a/3, so
<h3>b = 4h/5</h3><h3>a = 6h/5</h3>For Area:
A = b.a/2
as b = 4h/5 and a = 6h/5, so
<h3>A = 12h/25</h3>
