Answer:
a) $432
b) (i) $8970
Step-by-step explanation:
Given that:
Ratio of Cost of Hansi and Megan is 7 : 4.
Hansi's holidays cost = $756
Hansi's earnings in 2008 = $7800
In 2009, there are 15% more earnings than in 2008.
To find:
Cost of Megan's holiday.
Earnings in 2009 ?
Solution:
As per given question statement,
Let the holiday cost of Hansi = 7
Let the holiday cost of Megan = 4
As per question statement:
We have to find the value of 4 now.
b)(i)
Earnings in 2009:
$7800 + 15% of $7800
We believe that the angles are in quadrant 1.
<span>sin(6m-8) = cos (2m)
</span>⇒ 6m-8 = 90 - 2m
<span>
6m + 2m = 90 + 8
8m = 98
m = 98 / 8 = 12.25

Answer:
a) (x/7)^1/9=y
Step-by-step explanation:
f(x) = 7x^9
x/7= 7y^9/7
(x/7)^1/9=(y^9)^1/9
(x/7)^1/9=y
f^-1(x) is a fuction because it passes the vl test
Answer:
the first part of the book has 659 pages and the second part has 723 pages
Step-by-step explanation:
First we have to raise 2 equations, one that shows us the relationship between one part of the book and the other, and another equation that shows us that together they give us the total of pages
x = second part
y = first part
x = y + 64
x + y = 1382
As the first equation tells us that x = y + 64 we will replace x in the second equation with (y + 64)
x + y = 1382
(y + 64) + y = 1382
y + y = 1382 - 64
2y = 1318
y = 1318/2
y = 659
now we replace in the first equation to y by its value
x = y + 64
x = 659 + 64
x = 723
so the first part of the book has 659 pages and the second part has 723
